Segment Routing 101 and the Future of MPLS

Segment Routing 101 and the Future of MPLS

By Said Jilani, Sr Customer Solutions Architect

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 (called “segments”). The list of segments carried in the packet header provide a strict or a loose specification of the required network path or tunnel eliminating the need for transit nodes to hold and maintain that path/tunnel information.

Simplifying MPLS Transport Networks with Segment Routing

Simplifying MPLS Transport Networks with Segment Routing

By Said Jilani, Sr. Customer Solutions Architect

MPLS is a mature technology that has been deployed by service providers and private networks for many years. In a time of building pressure for organizations to modernize transport infrastructure to support new applications, MPLS enhances the performance, reliability, and scalability of IP based networks. Successful implementation has demonstrated a reduction of costs associated with maintaining complex expensive legacy TDM based transport network, improved scalability, and higher efficiency.
