  • Encoding explicit paths as segment routing segment lists
    Patent number: 9979601
    Abstract: A system and method are disclosed for generating segment routing (SR) segment lists. In one embodiment, a node receives information that identifies a path from a first node to a second node. Based on the received path, a set of segment identifiers that encodes the path is generated. A packet that is forwarded along the set of segment identifiers travels the received path.
    Type: Grant

  • Segment routing based wide area network orchestration in a network environment
    Patent number: 9647944
    Abstract: An example method for segment routing based wide area network (WAN) orchestration in a network environment is provided and includes monitoring a segment routing (SR) enabled WAN environment in at least near real-time by a path computation element (PCE) located outside the WAN, receiving an event notification at the PCE, and performing traffic engineering using SR to reroute traffic off shortest paths. In one embodiment, where a current state of the WAN is not pre-computed, performing traffic engineering comprises optimizing routes to remove violation of any utilization policies, deploying the optimized routes in the WAN, re-optimizing routes for other parameters, and further deploying the re-optimized routes in the WAN. In another embodiment, performing traffic engineering comprises optimizing routes to remove violation of any utilization policies and for other parameters, and deploying the optimized routes in the WAN.
