General Description
The XpressFlow Engine contains the switching data base interface and buffer management logic in order to do the switching decision making for unicast, multicast, and broadcast frames. Hardware assisted queue manager is incorporated to facilitate buffer management. It also provides a generic Management Bus interface to allow external processor to do initialization, learning, VLAN, and RMON support, etc. In addition, a XpressFlow Bus interface block is responsible for communicating with the Network Access Controllers through the XpressFlow message passing protocol.
