What is Segment Routing?

Segment routing is a routing paradigm that encodes a packet’s forwarding path as an ordered list of instructions, called segments, in the packet header, enabling source-based path control without per-flow state in transit routers. Expanded Explanation 1. Technical Function and Core Characteristics Segment routing uses a source-routed approach in which the ingress node attaches a segment list that represents the packet’s path or required functions. Network nodes forward packets by processing
