SR (Segment Routing)

An IP routing scheme that forwards  packets on the network based on a path dynamically  defined at the source node. Packet headers contain a list of

segments—an ordered list of nodes—that provide instructions  to be executed on subsequent network nodes. A key tool for  implementing soft Network Slicing, this routing framework  works over Multi-Protocol Label Switching (MPLS) or IP version  6 (IPv6) networks. It allows network operators to dynamically  adapt service-specific routing to avoid traffic congestion by  steering packets over different paths based on service level  requirements and the current state of the network.
