Abstract

A method and apparatus for virtual channel flow control at the link level, in which the virtual channel allocation is based on DestinationID. At each hop, cells destined for a particular destination are only allowed to occupy a part of the total available receiver buffer space. This flow control enables receiver cell buffer sharing, while maintaining per channel (per connection) bandwidth and loss-less cell transmission. A higher and more efficient utilization of receiver is achieved. In addition the virtual channel flow control method and apparatus described improve latency characteristics by making the virtual channel flow control more predictable, and thus provide a method for congestion control. At last the present invention implicitly addresses: Injection rate control; Failured network components (e.g. Host Adapters/IO-subsystems/Bridges/Switches/Routers/etc.). Both the above problems cause network buffers to be filled up and may lead to watchdog time-out at the transmitter. Watchdog time-out leads to retransmission, which causes performance degradation of the network.
