Method and system for a set of network appliances which can be connected to provide enhanced collaboration, scalability, and reliability

The present invention relates to the equipment in which network use is possible. This equipment can support remote monitoring of measured various data. This equipment can monitor the set of a variable or a variable, and outputs data according to a request. Furthermore, equipment can publish alarm, watch, warning, and/or other notices, when a variable consistents with a set point or it consistents with a characteristic change, a deviation, and/or change. Furthermore, this equipment can operate so that it may communicate with other equipment, and it is obtained. This communication may contain periodic Pingu of peer equipment. Thus, peer equipment can detect failure of the equipment in which other network use is possible, when expected Pingu is not received. Furthermore, this communication can enable establishment of the directory of the capability of various pieces of equipment. Thus, the group of equipment can perform many complicated actions more by carrying out grouping of the resource. [Selection figure] Fig. 2
