A network device executes a method to forward a packet that is encoded using an explicit list encoding of sparse multicast group membership information with Bit Index Explicit Replication. The method includes receiving a packet that includes a bitstring having a list of Bit Forwarding Router IDs (BFR-ids). The method further includes selecting a BFR-id identifying a destination Bit Forwarding Router (BFR) from the list for processing, looking up a forwarding bitmask for the destination BFR and a next-hop to reach the destination BFR in a bit index forwarding table, creating a copy of the packet, clearing the selected BFR-id from the packet, clearing BFR-ids from the packet and the copy of the packet based on the forwarding bitmask, and forwarding the copy of the packet to the next-hop neighbor.

A mobile telecommunications network includes a plurality of nodes for wireless communication with a mobile telecommunications device and a respective server associated with each of said nodes, each server having processing functions, wherein a processing function of a first one of the servers associated with a first one of the nodes is operable to support a communication session with the mobile telecommunications device to provide a service thereto. The processing function of the first one of the servers is operable to send data relating to the communication session to a second one of the servers associated with a second one of the nodes for use by a processing function of the second one of the servers to enable the processing function of the second one of the servers to support the communication session and provide continuity of the communication session if the mobile telecommunications device moves from registration with the first one of the nodes to the second one of the nodes.

An example system in accordance with an aspect of the present disclosure includes an inspection engine and a forwarding engine. The inspection engine is to identify whether a tunneled network packet is associated with the multicast group address and a VNI that is contained in the mapping table. The forwarding engine is to forward or discard the packet in response to whether the VNI is contained in the mapping table.

Methods and systems may be provided for installing a route entry associated with multicast traffic to a memory. Client devices may be notified of the route entry for advertisement by an active source device. The delivery group and delivery source may be retrieved from the information for the route entry. Multicast data trees may maintain delivery group and delivery source information for access.

A method performed by a network node. The method includes detecting a loss of connection at an incoming interface to an upstream neighbor of the network node, where the network node is in a multicast communication network that includes a multicast tree to provide connectivity from a common source node to one or more multicast recipient nodes. The multicast communication network further includes a set of one or more secondary paths to provide redundancy to the multicast tree, and sending a notification packet downstream toward the one or more multicast recipient nodes when the network node cannot re-route the multicast data traffic to allow the multicast data traffic to be received by the multicast recipient nodes, wherein the notification packet causes one or more downstream nodes to switch multicast reception to one or more of the set of one or more secondary paths to re-route the multicast data traffic.

A controller transmits a data packet to a node in a source routed forwarding network having a plurality of nodes configured to transfer data packets to one another via a plurality of links. The data packet includes a header. The header includes a source routed hop list defining a path of the data packet. The data packet is associated with a flow of data packets from a source to one or more destinations. The hop list includes a sub-tree identifier indicative of a multicast sub-tree.

A method of parallel processing by networked devices, in which distributed data in a network is accessed in parallel to provide results. Commands and queries by a user station define a set of such distributed data. The networked devices access the distributed data in portions, individually process each portion, conduct peer-to-peer communication to aggregate results from processing each portion, and individually determine whether and when to report results. Making effective use of network assets (such as processing and storage at each node), making effective use of concurrency of network assets, limiting bandwidth use between network assets and user stations, and limiting use of assets (such as processing and storage) at user stations.

A system, device, and method are provided to control dense-mode multicast traffic across a multilayer system containing an upper network and a tunnel across a lower network. An upstream multicast tunneling edge device (MTED) may indicate to downstream MTEDs, via control messages, the presence of a multicast source, group (SG) pair. The MTEDs may serve as routers or as intelligent bridges in the upper network. Each downstream MTED may create a forwarding state for the SG pair, determine tunnels for which the downstream MTED is to serve as an exit device and configure the tunnels to deliver the traffic. Lower network MTEDs of a tunnel may determine whether to transport multicast data for each SG pair such that multicast traffic routed by a corresponding MTED is carried. An MTED may be able to receive, through the tunnel, multicast traffic for one SG pair even after pruning itself for another SG pair.

A method and an apparatus for routing data packets. The solution in a communication network including a set of nodes, storing information regarding nodes of the network; and when transmitting a data packet to a destination node in the network, determining and including in the data packet the recipient identification; determining and including in the data packet the direction of the destination node in the network; determining and including in the data packet a hop count indicator indicating the number of node-to-node hops to the destination node; setting in the data packet the transmission direction indicator equal to a value corresponding to direction down and transmitting the packet.

Multiplex modules for use in carrier aggregation receivers are disclosed. In an exemplary embodiment, an apparatus includes an LNA multiplexer configured to receive a plurality of RF signals at a plurality of input terminals and to combine the RF signals into a combined RF signal that is output from an output terminal. The apparatus also includes an LNA demultiplexer configured to receive the combined RF signal at an input port that is connected to the output terminal and to distribute the combined RF signal to a plurality of output ports.
