  • Patent number: 11757776
    Abstract: A dynamic SRMS (DSRMS) in a MPLS network generates unique segment identifiers for nodes of the network lacking segment identifiers (SIDs). The DSRMS receives network information from other nodes of the network that may include, for example, Internal Gateway Protocol (IGP) routing information, advertised prefix values for the nodes, and label values used in MPLS routing. The DSRMS analyzes the information and identifies nodes of the network that are not associated with a SID. For each identified node, the DSRMS generates a unique SID and then announces the SID to other nodes within the network. Generating the unique SID may include executing a hashing function using the IP address of the identified node as an input.
