    Abstract: A method, apparatus, and computer-readable storage medium are disclosed for processing shared risk group (SRG) information in communications networks. The method includes processing, at a domain in a network, first network information comprising a plurality of SRG identifiers. The processing includes producing second network information comprising a smaller number of SRG identifiers than that of the plurality of SRG identifiers. The method further includes sending at least a portion of the second network information to a second domain in the network. The apparatus includes a network interface adapted to send network information comprising SRG information, a processor coupled to the network interface, and a memory coupled to the processor and adapted to store program instructions operable to carry out steps of the method. The storage medium is configured to store program instructions that when executed are configured to cause a processor to carry out steps of the method.

    Abstract: A method, apparatus, and computer-readable storage medium are disclosed for processing shared risk group (SRG) information in communications networks. The method includes processing, at a first network layer, first network information comprising a plurality of SRG identifiers. The processing includes producing second network information comprising a smaller number of SRG identifiers than that of the plurality of SRG identifiers. The method further includes sending at least a portion of the second network information to the second network layer. The apparatus includes a network interface adapted to send network information comprising SRG information, a processor coupled to the network interface, and a memory coupled to the processor and adapted to store program instructions operable when executed to carry out steps of the method. The storage medium is configured to store program instructions that when executed are configured to cause a processor to carry out steps of the method.

    Abstract: A method is provided in one example embodiment and includes receiving a request to create a path through a network, wherein the path originates on a first network device and terminates on the second network device; identifying a first controller associated with the first network device, wherein the first controller proxies control plane functions for the first network device; identifying a second controller associated with the second network device, wherein the second controller proxies control plane functions for the second network device; and computing the path using the first controller as a source and the second controller as a destination. The first controller installs the computed path on the first network device and the second controller installs the computed path on the second network device.

    Abstract: A method and apparatus for forwarding packets through a network domain that contains nodes that are label distribution protocol (LDP) enabled and nodes that are segment routing (SR) enabled. In one embodiment, the method may include a network node receiving a packet with a label attached thereto. The node swaps the label with a segment identifier (ID). The node then forwards the packet to an SR node. In another embodiment, the method may include a network node receiving a packet with a segment ID attached thereto. The node swaps the segment ID with a label. The node then forwards the packet to an LDP enabled node.

    Abstract: An apparatus and method are disclosed for fast reroute (FRR) for native segment routing (SR) traffic. In one embodiment, a node receives a packet that includes a segment routing (SR) segment identifier (ID) stack. The node determines what type of segment is designated as the active segment in the segment ID stack. Based, at least in part on the type of active segment, the node selects an update routine out of several possible update routines and performs the selected update routine. The update routine modifies the segment ID stack.

    Abstract: Bandwidth usage for an existing communication tunnel between a first device and second device is monitored. A determination is made that additional bandwidth is required for communication between the first network device and the second network device. A determination is made that for the addition of the additional bandwidth would exceed available bandwidth for the existing tunnel. Additional bandwidth is established between the first network device and the second network device.
