Segment Routing

What Does Segment Routing Mean?

Segment routing is a specific type of engineering for packet delivery that combines multiple packets in ordered lists for specific trajectory delivery. Segment routing provides an alternative to source routing and works with IPv6 network infrastructure.


Techopedia Explains Segment Routing

Essentially, in network segment routing, packets are assigned to a group of packets that can be labeled as a segment and transmitted over a data plane in the network. Segment routing represents a kind of SDN or software defined networking approach to packet routing and management. Generally, different segments are directed by analysis of system needs for a dynamic delivery process. For example, the system can identify the shortest path to a destination for separate segments.

In a way, segment routing is intended to complement multiprotocol label switching, a prior resource protocol, and can be built on top of MLPS.
