Facilitating network flows

摘要

In various embodiments, a system includes a switch comprising a resource that is shared between multiple objects. The switch comprises circuitry that determines a congestion metric for the switch in response to an amount of used of the resource by the objects. The circuitry determines a feedback parameter that is responsive to the congestion metric. The circuitry generates a congestion notification message that comprises a congestion feedback value responsive to the feedback parameter.;In further embodiments, a system includes a switch that processes data for a first data link layer access network. The switch includes circuitry that identifies whether a received packet originated from a source device that shares the same network layer access layer as the switch. If the source device shares the same network layer access network as the switch, the circuitry generates a congestion notification message comprising a congestion feedback value for the switch.
