0001This patent application claims the benefit of U.S. Provisional Patent Application No. 60/534,795 file January 7, 2004.

FIELD OF THE INVENTION

0002This invention pertains generally to the field of computer networks and more particularly to a schema for simplifying the process of configuring nodes in computer networks.

BACKGROUND OF THE INVENTION

0003The use of data communication networks continues to grow. In small as well as large corporate settings, wired local area networks (LANs) and wide area networks (WANs) have become an established feature of conducting business, and wireless networks are being increasingly employed. The use of network technology in the home, both wired and wireless, is a more recent phenomenon and has been slower to develop. In addition to facilitating Internet connectivity, home networking permits personal computing devices and various consumer electronic devices and appliances within the home to communicate with each other. Wireless technology, such as IEEE 802.11 wireless networks and networks of Bluetooth-enabled devices, is attractive in home as well as corporate environments for reasons of convenience, mobility and flexibility.

0004A principal impediment to the wider adoption of networking technology in the home and other non-corporate environments has been the difficulty experienced by non-expert users in configuring network devices. For example, it can be troublesome for such users to configure a device to function as a wireless access point (WAP). Setting up an ad hoc wireless network of peer devices (such as wireless PCs, wireless printers, and PDAs) is also typically a complex task. Each peer device must have the same network settings, and a secure ad hoc network typically requires each peer device to have a common WEP key, which must be communicated to the user of the peer device and entered manually. Thin client devices, such as digital audio receivers and wireless printers, which comprise an increasing number of home network devices, are particularly laborious to configure for network connectivity because they lack the convenient and intuitive I/O capabilities of conventional personal computers.

BRIEF SUMMARY OF THE INVENTION

0005In accordance with the invention, an Extensible Markup Language (XML) schema is used to generate XML files that are used to configure network devices to allow network functionality and connectivity. In an embodiment of the invention, an XML schema for wireless device configuration includes a network identifier element and a network encryption key element. In keeping with the features ofthe invention, the wireless device configuration schema further includes a connection type element, an authentication type element, an encryption type element, and a device mode indicator element. An automatic key element indicates whether a network key is provided automatically, and an 802.1x element indicates whether a device supports IEEE 802.1 x protocol. A frequency indicator element may also be used to indicate an operating frequency. A time-to-live element is used to define a time for which an instance of the schema is valid.

0006In another embodiment of the invention, an XML schema for wide area network (WAN) device configuration includes a DNS automatic element for indicating whether a DNS internet protocol (IP) address is provided automatically, a clone media access control (MAC) address element for indicating whether a MAC should be cloned, and a MAC address element. In keeping with the features of the present invention, the WAN device configuration schema further includes a DNS IP address element, a connection type element, and a WAN type element. The connection type element may include one of a point-to-point protocol (PPP) over Ethernet subelement and an IP subelement. The WAN type element may include one of a dynamic host configuration protocol (DHCP) subelement and a static IP subelement.

0007In yet another embodiment of the invention, an XML schema for local area network (LAN) device configuration includes a device name element, a device description element, and a LAN configuration element. The LAN configuration element may include one of a workgroup name subelement and a domain name subelement. The schema may further include a castle element.

0008In a further embodiment of the invention, an XML schema for broadband modem device configuration includes a session instance identifier element, a DHCP element for indicating whether DHCP is supported and a link modulation element for indicating a type of broadband connection. The broadband modem device configuration schema may further include a user name element, a password element, and an asynchronous transfer mode (ATM) encapsulation element for indicating a type of ATM encapsulation.

0009In still another embodiment of the invention, an XML schema for generating a device configuration report includes a manufacturer element, a model name element, and a serial number element. The schema may further include a manufacturer's uniform resource locator (URL) element, a device status element, a device type element, a network settings element, a wireless authentication element for indicating supported wireless authentication protocols, and a wireless encryption element for indicating supported wireless encryption protocols. In keeping with the features of the invention, the schema may also include a wireless configuration element for a wireless client device, a wireless infrastructure device, or a wireless access point device.

DETAILED DESCRIPTION OF THE INVENTION

0027Methods and systems for configuring network devices with a portable media device will now be described with respect to certain embodiments. The skilled artisan will readily appreciate that the methods and systems described herein are merely exemplary and that variations can be made without departing from the spirit and scope of the invention.

0028The present invention will be more completely understood through the following detailed description, which should be read in conjunction with the attached drawings. In this description, like numbers refer to similar elements within various embodiments of the present invention. The invention is illustrated as being implemented in a suitable computing environment. Although not required, the invention will be described in the general context of computer-executable instructions, such as procedures, being executed by a personal computer. Generally, procedures include program modules, routines, functions, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the invention may be practiced with other computer system configurations, including hand-held devices, multi-processor systems, and microprocessor-based or programmable consumer electronics devices. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices. The term computer system may be used to refer to a system of computers such as may be found in a distributed computing environment.

0029<b>Figure 1</b> illustrates an example of a suitable computing system environment 100 in which the invention may be implemented. The computing system environment 100 is only one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of the invention. Neither should the computing environment 100 be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in the exemplary operating environment 100. Although at least one embodiment of the invention does include each component illustrated in the exemplary operating environment 100, another more typical embodiment of the invention excludes some or all non-essential components, for example, input/output devices other than those required for network communications.

0030With reference to <b>Figure 1</b>, an exemplary system for implementing the invention includes a general purpose computing device in the form of a computer 110. Components of the computer 110 may include, but are not limited to, a processing unit 120, a system memory 130, and a system bus 121 that couples various system components including the system memory to the processing unit 120. The system bus 121 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures.

0031The computer 110 typically includes a variety of computer-readable media. Computer-readable media can be any available media that can be accessed by the computer 110 and includes both volatile and nonvolatile media, and removable and nonremovable media. By way of example, and not limitation, computer-readable media may comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and nonremovable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computer 110. Communication media typically embodies computer-readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above are included within the scope of computer-readable media.

0032The system memory 130 includes computer storage media in the form of volatile and/or nonvolatile memory such as read only memory (ROM) 131 and random access memory (RAM) 132. By way of example, and not limitation, <b>Figure 1</b> illustrates operating system 134, application programs 135, other program modules 136 and program data 137.

0033The computer 110 may also include other removable and nonremovable, volatile and nonvolatile computer storage media. By way of example only, <b>Figure 1</b> illustrates a hard disk drive 141 that reads from or writes to nonremovable, nonvolatile magnetic media, a magnetic disk drive 151 that reads from or writes to a removable, nonvolatile magnetic disk 152, and an optical disk drive 155 that reads from or writes to a removable, nonvolatile optical disk 156 such as a CDROM. Other computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, DVDs, digital video tape, solid state RAM, solid state ROM, and the like. The hard disk drive 141 is typically connected to the system bus 121 through a nonremovable memory interface such as interface 140, and magnetic disk drive 151 and optical disk drive 155 are typically connected to the system bus 121 by a removable memory interface, such as interface 150.

0034The drives and their associated computer storage media, discussed above and illustrated in <b>Figure 1,</b> provide storage of computer-readable instructions, data structures, program modules and other data for the computer 110. In <b>Figure 1,</b> for example, hard disk drive 141 is illustrated as storing operating system 144, application programs 145, other program modules 146 and program data 147. Note that these components can either be the same as or different from operating system 134, application programs 135, other program modules 136, and program data 137. Operating system 144, application programs 145, other program modules 146, and program data 147 are given different numbers herein to illustrate that, at a minimum, they are different copies. A user may enter commands and information into the computer 110 through input devices such as a tablet, or electronic digitizer, 164, a microphone 163, a keyboard 162 and pointing device 161, commonly referred to as a mouse, trackball or touch pad. These and other input devices are often connected to the processing unit 120 through a user input interface 160 that is coupled to the system bus, but may be connected by other interface and bus structures, such as a parallel port, game port or a universal serial bus (USB). A monitor 191 or other type of display device is also connected to the system bus 121 by way of an interface, such as a video interface 190. The monitor 191 may also be integrated with a touch-screen panel or the like. Note that the monitor and/or touch screen panel can be physically coupled to a housing in which the computing device 110 is incorporated, such as in a tablet-type personal computer. In addition, computers such as the computing device 110 may also include other peripheral output devices such as speakers 197 and printer 196, which may be connected through an output peripheral interface 194 or the like.

0035The computer 110 preferably operates or is adaptable to operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 180. The remote computer 180 may be a personal computer, a server, a router, a peer device or other network node, and typically includes some or all of the elements described above relative to the computer 110, although only a memory storage device 181 has been illustrated in <b>Figure 1</b>. The logical connections depicted in <b>Figure 1</b> include a LAN 171 and a WAN 173, but may also include other networks. For example, in the present invention, the computer 110 may comprise the source machine from which data is being migrated, and the remote computer 180 may comprise the destination machine. Note however that source and destination machines need not be initially connected by a network or otherwise, but instead, data may be migrated by way of any media capable of being written by the source platform and read by the destination platform or platforms. For example, one non-limiting instance of such a medium is a portable flash memory medium, sometimes referred to as a memory "key" or memory "stick." Other non-limiting examples will be given below.

0036When used in a LAN environment, the computer 110 is connectable to the LAN 171 through a network interface or adapter 170. The computer 110 may also include a modem 172 or other means for establishing communications over the WAN 173. The modem 172, which may be internal or external, may be connected to the system bus 121 by way of the user input interface 160 or other appropriate mechanism. In a networked environment, program modules depicted relative to the computer 110, or portions thereof, may be stored in the remote memory storage device. By way of example, and not limitation, <b>Figure 1</b> illustrates remote application programs 185 as residing on memory device 181. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers may be used.

0037Turning to <b>Figure 2</b>, a simple example of a computing environment usable in implementing an embodiment of the invention is depicted. In the example shown in <b>Figure 2</b>, a computer 200 communicates with a LAN 202 by way of a physical connection. Alternatively, the computer 200 communicates with the LAN 202 by way of WAN or other communications media. In an embodiment of the invention, the computer 200 is not initially in communications with any other device or network at all. In an embodiment of the invention, the computer 200 executes a program that generates network configuration settings in accordance with an XML schema. These settings are stored on a portable media device (PM) 204, such as a USB flash drive, Memory Stick, CompactFlash card, SmartMedia card, or other storage device. The computer 200 may directly accept the PM 204 by way of a built-in USB port, but alternatively is connected to a peripheral device, such as a card reader, that accepts the PM 204. In one embodiment, the PM 204 is a Bluetooth device that communicates wirelessly with the computer 200.

0038Once settings have been generated and stored on the PM, then, by attaching the PM 204 to various networkable devices, the appropriate network configuration settings are transferred to those devices, enabling network communications over a LAN 202, WAN 206, WLAN 208 or other types of computer networks. Exemplary networkable devices accepting the PM 204 include other computers 210 physically connected to the LAN 202. Although the other computers 210 are physically connected to the same LAN 202, they generally cannot communicate with one another until their network settings are appropriately configured. By attaching the PM 204, the appropriate network settings are transferred to the other computers 210, allowing for network communication between them. Similarly, a printer 212 accepting the PM 204 is configured for communications on the LAN 202, and/or on a wireless network 203, making the printer 212 accessible to the computer 200 and other devices on the LAN 202 and/or wireless network 203. A networkable television 214 and networkable telephone 216 also accept the PM 204 and are thereby configured for communications on the LAN 202 and/or wireless network 203. In an exemplary embodiment, wireless network 203 is an IEEE 802.11 standard wireless network. In an alternative embodiment, wireless network 203 is a WiMAX standard wireless network. However, those skilled in the art will appreciate that the wireless network 203 may be in accordance with any past, present or future wireless network protocol.

0039Other network hardware is likewise configured for network communication by attaching the PM 204. A wireless access point 218 accepts the PM 204 and is thus configured to allow communications between devices on the LAN 202 and other appropriately configured wireless devices. For example, if the computer 200 was equipped with wireless networking hardware, then it could connect to the LAN 202 by communicating wirelessly with the wireless access point 218. A modem 220 and router 222 also accept the PM 204 and are thereby configured to allow communication between devices on the LAN 202 and devices connected to a WAN 206 or the Internet 224. Notably, attaching the PM 204 allows for network configuration on devices such as modems 220 and routers 222 that typically do not contain input and output mechanisms such as keyboards and monitors.

0040The PM 204 is also used to configure wireless networks. For example, a notebook computer 230 and a tablet computer 232 each accept the PM 204 and are thus appropriately configured for wireless communications over wireless network203. Without the PM 204, a user would have to enter configuration settings ― including the network name and any security keys ― in order to access the wireless network 203. By attaching the PM 204, a computer is granted access to the wireless network 203 quickly and transparently. The computer networks configured by the PM 204 can be peer-to-peer networks (e.g., unmanaged "workgroups" that do not require a dedicated server) or domain-based networks such as client-server networks.

0041Turning attention to <b>Figure 3,</b> a software architecture for generating and storing network configuration settings is now described, in accordance with an embodiment of the invention. A Flash Config Wizard 302 is executed on a computer 300 and communicates with the computer through a wireless configuration application programming interface (API) 304 to generate wireless network configuration settings. In the Windows operating system environment, for example, the WZCDLG.DLL library can be used. In one embodiment, the Flash Config Wizard 302 is a standalone application. In another embodiment, the Flash Config Wizard 302 is integrated into a general network setup application. The Flash Config Wizard 302 generates XML files in accordance with a schema and outputs the XML files to the computer through a wireless provisioning API 306. The Flash Config Wizard 302 further outputs the XML files to an attached portable media device, such as a USB flash drive 308. The USB flash drive 308 stores files and applications for use in the network configuration process. An embodiment of the invention includes a network setup application 310 stored in the root of the USB Flash Drive 308 in order to facilitate the configuring of network settings on other devices. The network setup application is stored on the USB flash drive 308 by the Flash Config Wizard 302. When the USB flash drive 308 is attached to another device, that device can run the network setup application 310 to load the relevant network settings from the USB flash drive 308 to the other device.

0042The USB flash drive 308 further stores an autorun file 318. When the USB flash drive 308 is attached to a compatible device that recognizes the autorun file, the detection of the autorun file 318 automatically triggers the device to execute the network setup program 310. In this way, no user intervention is required to transfer the network settings to the device after the USB flash drive 308 has been attached. The USB flash drive 308 also stores a Flash Config Wizard copy 320. When the USB flash drive 308 is attached to another computer, the Flash Config Wizard 320 is executed by the computer to allow for manual guidance in transferring and modifying the network configuration settings.

0043Also stored on the USB flash drive 308 are several XML files representing the network configuration settings generated in accordance with a schema. These files are stored in a folder named SMRTNKEY on the USB flash drive 308. An LSETTING.XML file 312 contains settings for a LAN, and is generated using a LAN configuration schema. An NSETTING.XML file 314 contains settings for a WAN, and is generated using a WAN configuration schema. A WSETTING.XML file 316 contains settings for a wireless LAN, and is generated using a wireless configuration schema. An MSETTINGS.XML file 313 contains settings for a broadband modem, and is generated using a broadband modem configuration schema. By storing these network configuration settings, a single USB flash drive 308 can be used to configure a variety of devices (such as personal computers, routers, printers, PDAs, and WAPs) to communicate over a variety of types of networks.

0044After the network settings configuration files have been transferred to the USB flash drive 308, the USB flash drive 308 is installed in a configurable device 330. Configurable device 330 must provide support for USB Host Port, USB Mass Storage Devices, file allocation table (FAT) 16/32 file systems, and must include an XML Parser. Additionally access points must support 104 bit wireless encryption protocol (WEP), Infrastructure mode, and IEEE 802.11b protocol. The configurable device 330 includes a light emitting diode (LED) 334 that blinks three times after the network configuration files are downloaded from the USB flash drive 308.

0045The USB flash drive 308 is also used to store a device configuration file 311 for describing the configuration of a device to which the USB flash drive 308 has been attached. Configurable device 330 further includes a device configuration reporter 332 for generating the device configuration file 311 in accordance with an XML schema. Each device that is configured using the USB flash drive 308 generates an XML file describing the configuration of that device, and reports any fault conditions. The device then writes the device configuration file 311 to the USB flash drive 308, which is next attached to a PC that uploads the device configuration file 311. The PC uses the device configuration file, for example, in a diagnostic tool to determine why network configuration failed. In another example, the PC obtains a uniform resource locator (URL) of the device manufacturer from the device configuration file 311, and uses the URL to download, through hyper text transfer protocol over secure socket layers (HHTPS), an encryption key to access the device. The device configuration file 311 is stored in the SMRTNKY folder in a subfolder having the same name as the device. The device configuration file 311 is named using the last eight bytes of the media access control (MAC) address of the device.

0046<b>Figure 4</b> illustrates the operation of the Flash Config Wizard in generating the wireless, WAN, LAN, and broadband modem settings files. At step 410, the Flash Config Wizard reads in a schema, for example, a wireless configuration schema. At step 420, the Flash Config Wizard reads in wireless configuration settings, either through an API or user imputer. At step 430, the Flash Config Wizard generates a wireless configuration settings XML file in accordance with the wireless configuration schema, i.e. an instance of the wireless configuration schema. The wireless configuration settings XML file can then be copied to a portable media device and used to configure other devices.

0047In accordance with one embodiment of the invention, <b>Figure 5</b> illustrates a conceptualization of the wireless network settings schema 500. Schema 500 includes a wireless profile element 510, which defines the wireless configuration settings. Wireless profile element 510 includes a config subelement 520 for identifying the configuration and the author of the configuration. Config 520 includes subelements config ID 521, config hash 522, config author ID 523, and config author 524. Config ID 521 is a 36 character string for uniquely identifying the configuration, and must occur the wireless settings file once and only once. Config hash 522 is 20 digit hexadecimal number that may be optionally included to test the integrity of the wireless settings file. Config author ID 523 is a 36 character string for uniquely identifying the author of the configuration, and must occur in the wireless settings file once and only once.

0049The wireless profile element 510 includes a primary profile subelement 516, which must occur in the wireless settings file once and only once. The primary profile element defines the primary wireless configuration that will be used by the device. However, wireless profile 510 may also include an unlimited number of optional profiles 517. The optional profile 517 may define an alternative or additional wireless configuration that may be used if supported by the device. Both the primary profile 516 and the optional profile 517 are an instance of the type profile instance 530, which is also defined in wireless settings schema 500.

0050Profile instance type 530 includes an authentication type subelement 531. Authentication Type 531 is a string indicating the authentication protocol used by the wireless network, and may take a range of possible values including open, shared, WiFi Protected Access (WPA), WPA Pre-Shared Key (PSK), WPA-none, WPA2, or WPA2 PSK. Authentication type must occur in the profile instance once and only once. Encryption type 532 is a string indicating the encryption protocol used by the wireless network, and may take a range of possible values including none, Wireless Encryption Protocol (WEP), Temporal Key Integrity Protocol (TKIP), and Advanced Encryption Standard (AES). Authentication type 531 and encryption type 532 must occur in the profile instance once and only once.

0051Profile instance 530 further includes a network key subelement 533, which is a string that the PC will automatically generate, or alternatively, receive from the PC user. The network key 533 is used for encryption on the wireless network. In one embodiment of the invention, the network key 533 must occur in the profile instance once and only once, but may be blank. In an alternative embodiment, the network key 533 does not have to be included in the wireless settings file. Key index 534 is an optional integer for indicating the location of the specific key used to encrypt messages, and is used with WEP. Key provided auto 535 is a boolean subelement for indicating whether a network key is provided automatically, and can have a value of either 0 or 1. 802.1x 536 is a boolean subelement for indicating whether IEEE 802.1x protocol is used on the network, and can have a value of either 0 or 1. Key provided auto 535 and 802.1x 536 must occur in the profile instance once and only once. EAP Method 537 is a string for indicating the Extensible Authentication Protocol used, and may have a value of EAP-TLS, PEAP-EAP-MSCHAPv2, or PEAP-EAP-TLS. This setting is used for 802.1x authentication only. TTL 538 is an optional integer for indicating a time-to-live that specifies the length of time a network key is valid.

0052An exemplary implementation of the wireless network settings schema 500 is included in Appendix A following this description. An example instance of a wireless network settings file generated in conformance with the schema in Appendix A is included in Appendix B following this description.

0053In accordance with another embodiment of the invention, <b>Figure 6</b> illustrates a conceptualization of the WAN network settings schema 600. Schema 600 includes a WAN profile element 610, which defines the WAN configuration settings. WAN profile element 610 includes a config subelement 620 for identifying the configuration and the author of the configuration. Config 620 includes subelements config ID 621, config hash 622, config author ID 623, and config author 624. Config ID 621 is a 36 character string for uniquely identifying the configuration, and must occur the WAN settings file once and only once. Config hash 622 is 20 digit hexadecimal number that may be optionally included to test the integrity of the WAN settings file. Config author ID 623 is a 36 character string for uniquely identifying the author of the configuration, and must occur in the WAN settings file once and only once. Config author 624 is a string with a maximum length of 128 indicating the name of the WAN settings file, and must occur in the WAN settings file once and only once.

0054WAN profile element 610 further includes subelements for defining each of the WAN configuration settings. The WAN profile 610 includes the subelement clone MAC address 611, which is a boolean that indicates whether the MAC address of the client should be cloned for use in the WAN. Clone MAC address 611 must occur in the WAN settings file, and takes a value of 0 or 1. MAC address 612 is an 8 character hexadecimal number that defines the MAC address of the client. DNS IP auto pushed 613 is a boolean that indicates whether a domain name service IP address is automatically pushed to the DHCP client.
