segment routing in ipv6

Segment Routing is a new routing paradigm that aims to optimize, simplify, and improve the scalability of IP/MPLS based networks. Segment Routing utilizes source-based routing scheme where a network node steers a packet based on a list of instructions carried in the packet header

Segment Routing (SR) is a new traffic-engineering technology being developed by the IETF’s SPRING Working Group. Two forwarding plane encapsulations are being defined for SR: Multiprotocol Label Switching (MPLS) and IPv6 with a Segment Routing Extension Header

Reaping the benefits of ipv6 segment routing

Computer networks connect terminal nodes, or endhosts, and enable them to communicate by exchanging data. In IP networks, network nodes are assigned a unique, network-wide identifier. This identifier is called an IP address. The information transiting on IP networks is
