In one embodiment, the present invention includes a method for receiving incoming data in a processor and performing a checksum operation on the incoming data in the processor pursuant to a user-level instruction for the checksum operation. For example, a cyclic redundancy checksum may be computed in the processor itself responsive to the user-level instruction. Other embodiments are described and claimed.

Performing a cyclic redundancy checksum operation responsive to a user-level instruction

In an embodiment, an apparatus is provided that may include an integrated circuit including switch circuitry to determine, at least in part, an action to be executed3 involving a packet. This determination may be based, at least in part, upon flow information determined, at least in part, from the packet, and packet processing policy information. The circuitry may examine the policy information to determine whether a previously-established packet processing policy has been established that corresponds, at least in part, to the flow information. If the circuitry determines, at least in part, that the policy has not been established and the packet is a first packet in a flow corresponding at least in part to the flow information, the switch circuitry may request that at least one switch control program module establish, at least in part, a new packet processing policy corresponding, at least in part, to the flow information.
