Modular and scalable switch and method for the distribution of fast ethernet data frames

摘要

For fast ethernet switches, a modular and scalable structure using programmable one-port communication modules is disclosed. The forwarding process is sequential and operates in a store-and-forward mode. The design follows a strictly predictable scheme. The forwarding process, the distribution logic, maximum latency and programmable functions, i.e. traffic monitoring capabilities, traffic filtering/policing capabilities and network management function capabilities are described and explained with reference to typical examples.
