Shared memory based network switch and the network constructed with the same

摘要

A shared memory based network having a transferring network switch and a receiving network switch. In this network, each network switch has a stack, queues corresponding to output ports and a dared control port. The stack stores available buffer addresses of the shared memory. Each of the queues stores to-be-accessed buffer addresses of the corresponding output port. The shared control port is driven to indicate states of the shared memory based network, so that th stack of the transferring network switch is identical with the stack of the receiving network switch. The shared memory can be read by all output ports of both the transferring network switch and the receiving network switch according to their corresponding queues.
