Transparent Bridging Support In High Speed Interworking Units

摘要

The emerging data rates in high speed networks impose increasingly high performance requirements on interworking units.Novel architectural coneepts providing a high degree of parallelism are needed for the implementation of multiport transparent bridges interconnecting gigabit speed networks.The modular architecture of the High Performance Transparent Bridge(HPTB) is based on an internal switching component interconnecting various concurrently operating network attachment units.The bridge protocol entities are property partitioned and performance critical tasks,such as management of the filtering data base and buffer management,are provided with special hardware support.The HPTB is capable of concurrently bridging asynchronous,synchronous and isochronous traffic among heterogeneous networks,including traditional frame-based networks,such as LANs,and cellbased networks using ATM technology.
