摘要： In one embodiment, a packet switching device includes one or more host devices and a cascade of aggregation nodes. The aggregation nodes aggregate customer traffic and communicate it with the host device. Typically the aggregation nodes are remotely located from the host device. The host device may be connected to one or both ends of the cascaded topology of aggregation nodes. In one embodiment, the cascaded topology of aggregation nodes automatically configures itself using initiation packets. In one embodiment, the cascaded topology of aggregation nodes reacts to detected faults, such as by changing direction packet traffic is sent through the cascaded topology. By cascading aggregation nodes, in contrast to having each aggregation node connected to the host device via one or more point-to-point links, communications costs are decreased in one embodiment.

摘要： Techniques for load balancing network traffic over virtual point-to-point data links at a data-link layer include determining a particular group of virtual point-to-point data links that reach a particular local area network of one or more network nodes. A particular data-link address for a particular node of the particular local area network is associated with each virtual point-to-point data link of the particular group. When a data packet is received that includes data that indicates the particular data-link address as a destination; one virtual point-to-point data link of the group is determined to balance traffic among the group. The data packet is sent only over the one virtual point-to-point data link. These techniques enable virtual point-to-point data links through two or more intermediate network nodes, such as a pair of provider edge nodes, to be bundled for load balancing purposes.

摘要： In one example embodiment, a method may include receiving a service advertisement message from an advertising node via a ring-based network, determining a service map based on the received service advertisement message, and transmitting data to the advertising node. The service advertisement message may include an address of the advertising node and a service ID for one or more services. The service map may indicate an association between the address of the advertising node and the one or more service IDs. The transmitting data to the advertising node may include transmitting data for at least one of the services to the advertising node based on the service map via the ring-based network.

摘要： A method for providing inter-ring protection in shared packet rings includes identifying an active node which is connected to a ring interconnect node on the same ring as the active node and connected to a peer node on a different ring with a ring interconnecting link. When the active node is in active mode and receives notification of a failure of the ring interconnecting link or peer node, the active node sends a message to the ring interconnect node so that the ring interconnect node switches from standby mode to active mode. The active node is then changed to standby mode.

摘要： A method for preventing loops in a ring topology of a computer network is disclosed. The method includes receiving a packet at a node on a shared packet ring and inserting a header containing an ID identifying the node at which the packet was received on the ring as an originating node. The packet is forwarded onto the ring and the ID is checked when received on a node. The packet is dropped if the ID identifies the node as the originating node.
