초록 ▼

A novel switch architecture maintains the sequence of packet cells, received at one port of a multicast port group, during subsequent transfer of the cells to the remaining ports of the group. The novel architecture includes a 2-stage buffering arrangement whereby the first stage comprises a plurality of local buffers, each associated with a port of the switch, and the second stage comprises a single, global buffer. Each local buffer services its associated port of the multicast port group by temporarily storing incoming packet cells until a complete packet is received at that port, at which time the packet cells may be passed to the global buffer as outgoing cells. The global buffer services the remaining ports of the multicast port group by forwarding copies of the outgoing cells, in sequence, to those ports.

Apparatus in a cell-switched network, said apparatus having a multicast port group comprising a plurality of ports, said apparatus comprising: a plurality of local buffers, each associated with a respective one of said plurality of ports and configured to receive a plurality of packet cells at an incoming port of said multicast port group; a global buffer having inputs coupled to each of said plurality of local buffers and outputs coupled to each of said plurality of ports, said global buffer configured to store, in sequence, said plurality of packet cells from said plurality of local buffers and further configured to forward said plurality of packet cells, in sequence, to outgoing ports of said multicast port group; control means, coupled to said plurality of local buffers and said global buffer, for maintaining the integrity of each packet of said plurality of packet cells and for controlling the transfer of said plurality of packet cells from said each of said plurality of local buffers to said global buffer once said each of said plurality of local buffers has received an entire packet of said plurality of packet cells, and for controlling the transfer of said packet cells from said global buffer to said outgoing ports, through a multicast virtual circuit.
