Vlan table management system for memory efficient lookups and inserts in hardware-based packet switches

Here describes in hardware's packet switching-based and device for a bellows fast VLAN method and device for searching. The switch introduces of control cabinet (TME), which data search and method. The TME is divided to form two memory, comprising a data entry ('data entry hole( 203), comprising a power and effective blade ('indicating hole( 205). The TME/hash (206), and operating shaft (208), tabulates the chassis a reader freely (210) and control element (214). Reader/hash obtaining content from the key; the key can be a square VLAN. The indicator of the operating formed by the key for addressing memory, retrieve data. The operating and host is further takes for reading a/deletes the data the memory, and is provided with a power management.
