摘要： An arbiter is provided for resolving contention on synchronous packet switched busses, including busses composed of a plurality of pipelined segments, to ensure that all devices serviced by such a bus are given fair, bounded time access to the bus and to permit such devices to fill all available bus cycles with packets. Flow control for shared memory multiprocessors is readily implemented with this arbiter because the arbiter supports different types of arbitration requests and the prioritization of such arbitration requests by type.

摘要： In some embodiments, a non-transitory processor-readable medium stores code representing instructions to be executed by a processor. The code causes the processor to receive, from a source peripheral processing device, a portion of a data packet having a destination address associated with a destination peripheral processing device. The code causes the processor to identify, based on the destination address, a service to be performed on the portion of the data packet. The code causes the processor to select, based on the service, an identifier of a service module associated with the service. The code further causes the processor to send the portion of the data packet to the service module via a distributed switch fabric such that the service module performs the service on the portion of the data packet and sends the portion of the data packet to the destination peripheral processing device via the distributed switch fabric.

摘要： A multicast-capable firewall allows firewall security policies to be applied to multicast traffic. The multicast-capable firewall may be integrated within a routing device, thus allowing a single device to provide both routing functionality, including multicast support, as well as firewall services. The routing device provides a user interface by which a user specifies one or more zones to be recognized by the integrated firewall when applying stateful firewall services to multicast packets. The user interface supports a syntax that allows the user to define subsets of the plurality of interfaces associated with the zones, and define a single multicast policy to be applied to multicast sessions associated with a multicast group. The multicast policy identifies common services to be applied pre-replication, and exceptions specifying additional services to be applied post-replication to copies of the multicast packets for the one or more zones.
