A system and method for credit-based link level flow control. In one embodiment, a byte-based flow control mechanism is based on a sender effectively maintaining a buffer state at the receiver. In maintaining a buffer state at the receiver, the sender is provided with information regarding byte expansion at the receiver. This byte-expansion information can be used by the sender to identify the amount of additional storage needed by the receiver when storing a packet transmitted by the sender in the receiver's packet buffer.

System and method for credit-based link level flow control

Methods, systems, and devices are provided for managing flow of datagram traffic, generally across networks. According to some of these methods, a flow control mechanism is used to avoid over-subscription of some ports without pausing extended areas of a network. According to other methods, a congestion control mechanism is used to minimize datagram traffic between a port sending datagrams to an over-subscribed port and the over-subscribed port itself.
