摘要： A method includes storing, at a first network device configured to communicate with at least one set top box (STB) and at least one digital video recorder (DVR), information identifying parameters associated with bandwidth in a home network. The method may also include receiving, at a first network device in the home network, a request having a corresponding first bandwidth and identifying a class of traffic associated with the request. The method may further include determining whether the first bandwidth is less than an available bandwidth associated with the identified class of traffic, approving the request when the first bandwidth is less than the available bandwidth, and modifying the available bandwidth associated with the identified class of traffic in response to approving the request.

摘要： The present invention provides improved work schedulers for computer systems and communication processors. A preferred embodiment of the present invention includes systems with buffer memory for storing one or more communication packets or work requests arranged on a plurality of scheduling queues and information for controlling the scheduling of the queues, with output processors for outputting packets from the buffer memory; and with control processors for performing the scheduling methods of this invention. The scheduling methods repetitively initialize each queue's service credits, repetitively process each queue in a round-robin order by granting each queue with remaining service credits no more than one quantum of service and updating that queue's service credits to reflect the service actually used and the service available for use but not actually used.

摘要： The present invention provides switches and routers, preferably with fully-connected mesh fabrics, that transmit data through the switch fabric in variable-size data units. Variable-size data units allow switches and routers to provide throughputs close to hardware capabilities, eliminating the need for over-capacity hardware in the switch fabric and other components. Along with variably-size data units, preferred embodiments of this invention include scheduling methods that provide fair allocation of pre-determined bandwidths to different protocols, to different classes of service within protocols, and to different resources within the switch by use of certain weighted, fair scheduling methods. The switches and routers of this invention are particularly directed to multi-protocol, high-throughput communication applications, but may have wide applicability in systems generally where data packets are switched or routed.

摘要： The present invention relates to communications networks, and more particularly to packet switching and routing devices used in communication networks that provide efficient multicast services. The invention provides methods and systems for switching and routing of multicast data packets in two stages. In particular, in the first stage a received multicast data packet is in an internal multicast operation by an ingress line card across a switching fabric to a plurality of egress line cards through which multicast destinations of the packet are reachable. In a second stage each egress line card further replicates the data packet to the actual transmission links across which the multicast group are reachable. This invention also includes system performing this method. The invention reduces the service time for the multicast packets making it the same as for the unicast packets, and provides for better system throughput in comparison to traditional systems.

摘要： The present invention provides hierarchical structures of queues and schedulers for switches and routers with, preferably fully-connected, mesh fabrics, for efficiently and properly handling the quality or service requirements of multiple network services, such as ATM and IP, in switch or router. The switches of this invention provide, for example, fair allocation of bandwidths to different network services, to different QoS classes within network services, and to different resources within the switch by use of, preferably, weighted, fair scheduling methods. The switches and routers of this invention are particularly directed to multi-protocol, high-throughput communication application, but may have wide applicability in systems generally where data packets are switched or routed.
