Abstract: 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.

Abstract: A mobile architecture system includes a plurality of connection nodes each comprising an access interface and at least one network interface. A plurality of aggregation layer devices are each coupled to respective sets of connection nodes to form aggregation regions. A backhaul network is coupled to each of the aggregation layer devices, and a mobility entity is coupled to the backhaul network, wherein each of the connection nodes is configured to receive attachment requests from at least one user device. The aggregation layer devices are configured to assign IP addresses to user devices connected to connection nodes coupled to the respective aggregation layer devices. The aggregation layer devices are configured to determine IP routes from the backhaul network to the connection nodes based on the assigned IP addresses. The aggregation layer devices are further configured to notify respective connection nodes regarding the IP addresses assigned to connected user devices.

Abstract: 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.

Abstract: A network device receives a label-switched-path (LSP) labeled data packet, maps the LSP labeled data packet to an input queue, maps a data packet in the input queue to an output queue based on a received LSP label value and a received exp label value, and transmits the LSP labeled data packet from the output queue.

Abstract: A device may assign a virtual local area network (VLAN) to one or more specific links in a link aggregation group (LAG), and send traffic from the VLAN on the assigned one or more specific LAG links. Traffic from the same VLAN may be sent on one link in the LAG by selecting a hashing criterion or by pinning the VLAN to a primary link in the LAG and another link for redundancy purposes.

Abstract: A device may receive a bandwidth (B) available on each link of a link aggregation group (LAG) that includes a number (N) of links, assign a primary LAG link and a redundant LAG link to a virtual local area network (VLAN), set an available bandwidth for primary link booking to (B?B/N), and set an available bandwidth for redundant link booking to (B/N).

Abstract: 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.

Abstract: A device generates a service protection factor (SPFi) for links (N) on a link aggregation group (LAG), determines a traffic allocation bandwidth on the LAG for a service class based on the service protection factor (SPFi) and a congestion guard factor (CGFi), and restricts the traffic allocation bandwidth on the LAG. The service protection factor (SPFi) may guarantee a service availability target in the presence of link failure, and the congestion guard factor (CGFi) may protect against link overload that may arise from imperfectness in traffic load balancing across links in the LAG.
