As such, the controller device may then instruct the given routing device to segment route the selected flow via the particular egress peering segment. In another embodiment, an egress border router shares its BGP egress peering segments, and receives a flow to segment route. The egress border router may determine, from a segment route contained within the flow, to which particular egress peering segment of the border router to segment route the flow, and forwards the flow out of the domain via the particular egress peering segment. | 2015-10-22 |
20150304207 | Route Determination in a Multi-Hop Network Using Multiple Routing Metrics - The proposed technology provides a computationally efficient way to find suitable routes under consideration of multiple metrics. The considered multi-hop network is represented by a connected graph having nodes and links interconnecting the nodes. The method comprises the step (S | 2015-10-22 |
20150304208 | TOPOLOGY-AWARE PACKET FORWARDING IN A COMMUNICATION NETWORK - A method includes forwarding one or more packets from a first addressable computing element to at least a second addressable computing element based on a topology-aware address assigned to the second addressable computing element. The topology-aware address includes a set of identifiers representing one or more topology attributes associated with the second addressable computing element. | 2015-10-22 |
20150304209 | DYNAMIC CONTROL CHANNEL ESTABLISHMENT FOR SOFTWARE-DEFINED NETWORKS HAVING CENTRALIZED CONTROL - Dynamic control channel establishment for an access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a network to access nodes. For example, a method includes receiving, by the centralized controller, a discover message originating from a network node, which includes an intermediate node list that specifies a plurality of network nodes the discover message traversed from the network node to an edge node, determining, based on the plurality of nodes specified by the discover message, a path from the edge node to the network node, allocating each of a plurality of Multi-protocol Label Switching (MPLS) labels to a respective outgoing interface of each of the plurality of network nodes, and outputting one or more control messages for configuring the network node, wherein the control messages are encapsulated within a label stack comprising the allocated plurality of labels. | 2015-10-22 |
