BACKWARD CONGESTION NOTIFICATION

摘要

In one embodiment, an apparatus comprises a network interface system having at least one input port configured for receiving frames and a logic system comprising at least one logic device. The logic system may be configured to perform the following functions: determining a source address and a destination address of a frame received at an ingress port; calculating a flow hash based at least upon the source address and the destination address; forming a congestion management (“CM”) tag that includes the flow hash; inserting the CM tag in the frame; and forwarding the frame to the destination address.

主权项

1. An apparatus, comprising:
a memory; and a processor coupled to the memory, at least one of the processor or the memory being adapted for: receiving a first frame at a first ingress port of a first network device; calculating a flow hash based at least upon a source address of the first frame and a destination address of the first frame; inserting a congestion management (“CM”) tag in the first frame, wherein the CM tag comprises the flow hash and an indication for a second ingress port of a second network device to add a backwards congestion notification (“BCN”) address in the CM tag; and forwarding the first frame to the destination address.
