Network proxy for high-performance, low-power data center interconnect fabric

摘要

A system and method are provided for network proxying. The network proxying may occur in a node of a fabric or across nodes in the fabric. In the network proxying, the node has a processor with a low power mode and the system remaps, by a management processor of the node, a port identifier for a processor that is in a low power mode to the management processor. The management processor then processes a plurality of packets that contain the port identifier for the processor that is in the low power mode to maintain a network presence of the node.

1. A node, comprising:
at least one processor associated with at least one first internal port, wherein the at least one first internal port has a first address; a management processor associated with a second internal port, wherein the second internal port has a second address; and a port remapping component configured to indicate that the first address is remapped to the second address, wherein the port remapping component is configured to activate a port remapping enable field, and wherein the port remapping enable field is specific to a given channel; wherein the management processor is configured to disable a first-in first-out buffer of the at least one processor and to receive traffic destined for the at least one processor as a proxy of the at least one processor via the port remapping component and in response to the at least one processor being in a low power state.
