摘要： A system for controlling packet forwarding through a dual-homed connection between first and second network domains, the dual-homed connection including two peer nodes connected to the first and second network domains. A sub-ring network is instantiated in the first network domain, and includes at least two nodes connected in a linear topology between a pair of end-nodes. Each end-node corresponds with a respective one of the peer nodes. A virtual link through the second network domain for conveys traffic of the sub-ring network between the peer nodes, and closes the sub-ring network to define a ring topology. Each of the nodes of the sub-ring network is controlled to forward packets of the sub-ring network in accordance with a ring network routing scheme.

摘要： A method of routing traffic through a packet network having a mesh physical topography. At least two types of network primitive are defined, each type of network primitive providing a respective model of traffic forwarding through at least two neighbor nodes of the network. A network model encompassing at least a portion of the network is constructed using a set of two or more interconnected network primitives. The network model has nodes and links corresponding to respective nodes and lines of the network. Respective forwarding information is computed for each node of the network model. For each node of the network model, the respective computed forwarding information is installed in a forwarding database of the corresponding node of the network, such that traffic is forwarded by each node of the network in accordance with the respective computed forwarding information.

摘要： A system for controlling packet forwarding through a point-to-point (p2p) connection between first and second end nodes of a packet network domain having a mesh topology. The system comprises a sub-ring network instantiated in the network domain, the sub-ring network comprising a pair of topologically diverse ring spans extending between the first and second end nodes. Each of the end nodes is controlled to forward packets of the p2p connection through the sub-ring network in accordance with a ring network routing scheme, and an intermediate node traversed by one of the ring spans is controlled to forward packets of the p2p connection through the ring span in accordance with a linear path routing scheme.

摘要： A method automatically discovers a topology of a communication network ring. The ring includes a plurality of nodes. Each node includes a first port and a second port. A ring topology request or a response to the ring topology request is received from at least one node on the ring. The ring topology request or the response to the ring topology request includes an identification of the at least one node and an indication of a hop count needed to reach the at least one node. The ring topology request or the response to the ring topology request is forwarded to at least one neighboring node on the ring through the first port. The topology is determined based on the identification of the at least one node, the hop count, and an identification of the first port.

摘要： An edge device is used to support a backbone provider bridging network to facilitate interconnection of a plurality of networks. The edge device is coupled between the backbone and a first one of the networks, and is operable to encapsulate data units received from the first network with a header, and to forward the encapsulated data unit to the backbone. The header is indicative of a tunnel that is used to support traffic from the first network to a second network over the backbone. The edge device also de-encapsulates data units received from the backbone that are destined for the first network.

摘要： Systems and methods for ring protection switching in a network based on selectively blocking and unblocking a port include forwarding traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop; and selectively blocking and unblocking traffic on the port to provide the ring protection switching over the closed loop, wherein the selectively blocking and unblocking is performed based on a management channel that utilizes a second service identifier that is a different type from the first service identifier.

摘要： A method, a network, and a network element use dynamic packet traffic performance adjustment techniques. In an exemplary embodiment, the dynamic resizing techniques utilize different packet connections providing connectivity to same sites between which bandwidth resizing is needed. Each of the packet connections has a separate and independent bandwidth profile that governs an amount of traffic that is dispatched over each packet connection. A network element sourcing traffic into the packet connections uses bridge functionality that dispatches client traffic onto all of the packet connections or an individual packet connection. This effectively means that the transport network bandwidth utilization is only consumed by a single packet connection, i.e., the packet connection-A (even through there are multiple configured). The network element sinking the traffic selects from a single active packet connection.
