US 2014/0156867 A1 · OFFLOAD PROCESSING INTERFACE

Abstract

Disclosed are various embodiments providing offload processing circuitry of a network switch. The offload processing circuitry receives an administrative packet from a network switch, the offload processing circuitry being communicatively coupled to a network switch via an Ethernet interface. The offload processing circuitry identifies a receive offload header associated with the administrative packet, the receive offload header comprising a media access control (MAC) address associated with the offload processing circuitry. The offload processing circuitry updates a state machine based at least upon the administrative packet. The offload processing circuitry transmits packets to a network switch by encapsulating it in offload header. The network switch uses the offload header to forward the packet to a proper port.

Dependent claims

A system comprising:

a plurality of ports, each port being configured to receive packets;
and
a receive module, the receive module being configured to:
determine whether a received packet is an administrative packet that requires processing;
encapsulate the administrative packet with an offload header, the offload header comprising a port identifier that specifies one of the plurality of ports;
and
route the administrative packet to the one of the plurality of ports to facilitate an offload processing of the administrative packet.
