Packet switching
First Claim
1. An apparatus comprising:
- at least one processor to execute switch control instructions;
a plurality of queues to store packets; and
switch circuitry to;
determine flow information from a received packet;
access packet processing policy information associated with the flow information;
determine whether to block the received packet based on at least a portion of the flow information, at least a portion of the packet processing policy information, and a mask stored in a content addressable memory;
when the received packet is not blocked, select a queue from among the plurality of queues based at least in part on an indication of a traffic priority class parsed from the received packet; and
place the received packet in the selected queue.

Abstract
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.
