  • Link failure recovery method and apparatus
    Patent number: 8804501
    Abstract: A method of routing packets across a packet switched network domain, comprising a multiplicity of nodes. Each node comprises an ingress interface and an egress interface. For each destination node a default and a detour branching are defined, each specifying a route to the destination node. For each two-edge connected node the default and detour branchings do not share a common ingress interface.

  • System and method of implementing lightweight not-via IP fast reroutes in a telecommunications network
    Patent number: 8780696
    Abstract: A system, method, and node for implementing lightweight Not-via Internet Protocol fast reroutes of a packet in a telecommunications network between a first node and a destination node. The method determines a shortest path between the first node and the destination node and two redundant trees between the first node and the destination node. Each redundant tree provides an alternate path from the first node and the destination node. When a failure in a link between the first node and the destination node is detected, the packet is forwarded to the destination node via a first redundant tree, and if not available, via a second redundant tree. If the second redundant tree is not available, the packet is dropped. If no failure in the link between the first node and the destination node is detected, the packet is sent via the determined shortest path to the destination node.
