    摘要： Systems and methods for IP multicast packet burst absorption and multithreaded replication architecture are disclosed. Replications of IP multicast packets are performed in a control plane of a network device. The network device may include a data plane for transmitting data between ingress and egress ports and a control plane including a shared transmit/receive queue infrastructure configured to queue incoming multicast packets to be replicated on a per ingress port basis and to queue transmit packets, and a multicast processing engine in communication with the shared queue infrastructure and including a circular replication buffer to facilitate multithreaded replication of multicast packets on a per egress virtual local area network (VLAN) replication basis. The shared transmit/receive queue infrastructure may dynamically allocate memory between the transmit and receive multicast queues.

    摘要： Either vehicle traffic or financial markets data is regularly broadcast in a fixed size packet over a wireless network in a push manner to one or more wireless receiver devices located within a particular service coverage region. A data center stores information specific to the particular region including drive-times strings metadata, drive-times data, drive-times route metadata, traffic incident data and financial markets indicators data. The data center decides upon a particular type of information to be placed into a payload of a next packet to be broadcast and pre-formats this information accordingly without receiving any information from the receiver devices. Data structures are provided which contain data representing the drive-times strings metadata, drive-times data, drive-times route metadata, traffic incident data and financial markets indicators data.

    摘要： A method and apparatus to perform a multi-field matching search. A search unit groups single fields of a multiple-field source into a search target having multiple-field keys (MFKs) whose single fields correspond to the single fields in multiple-field vectors (MFVs) of entries in a data structure. The search unit generates a set of queries based, at least in part, on the MFKs, where each query has a different MFK as a lead MFK. The search unit determines, based, at least in part, on a query, whether the non-wildcard values in the MFVs of an entry match the non-wildcard values in corresponding MFKs of the search target. If no entry has non-wildcard values in the MFVs that match the corresponding non-wildcard values in the MFKs, the search unit searches for, based, at least in part, on the set of queries, the entry having non-wildcard values in a MFV that match the non-wildcard values in a corresponding lead MFK, plus remaining MFVs that match corresponding remaining MFKs based on matching the non-wildcard values and wildcard values.

    摘要： A method according to one embodiment may include transmitting a plurality of packets through control pipeline circuitry of an integrated circuit of a switch. The control pipeline circuitry may be capable of making a plurality of memory requests to memory of the switch in response to the plurality of packets. The method may further comprise staggering the plurality of memory requests so that each of the plurality of memory requests occurs during a different one of a plurality of time slots. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
