Title:
MULTIPORT LAN BRIDGE
Document Type and Number:
Japanese Patent JP2537017
Kind Code:
B2
Abstract:
PURPOSE: To obtain an efficient interconnecting device by providing a heterogeneous multiport bridge which performs frame filtering, copying, transfer, and header conversion at relatively short time intervals.
CONSTITUTION: Respective LANs 1 to N are connected through front-end modules 1' to N' of a LAN controller 1. A microcontroller is connected to a high-speed system control/address/data bus 10 through a microprocessor glue logic mechanism 21. The microcontroller administers the interconnecting device. A transparent bridge bus 22 is coupled with bridge port frame handlers 1" to N" through independent isolator(ISO) circuit means 24 to 24N. A delay bridge control/supervision unit 26 is connected to the bus 22. The bus 22 transmits header information and signature information between the unit 26 and respective handlers 1" to N".
