ISIS-SR with TI-LFA in OcNOS
Topology-Independent Loop-Free Alternate (TI-LFA) is a key Fast Reroute (FRR) mechanism used in network routing. It provides robust backup path options that are pre-computed and topology-independent, enhancing network resiliency. TI-LFA plays a critical role in minimizing downtime and ensuring rapid convergence in the face of link or node failures, thereby improving overall network reliability and […]

Segment Routing Extension with IGP (IS-IS) in OcNOS
IS-IS Protocol Basics: IS-IS is an Interior Gateway Protocol (IGP) used for routing within Autonomous Systems (AS) in IP networks. It operates on the link-state routing algorithm where routers exchange link-state information to build a complete topology of the network. Integration of IS-IS with Segment Routing: IS-IS Segment Routing extends the IS-IS protocol to support […]

Segment Routing (SR): Understanding the WHY, WHAT, and HOW
In the world of networking, evolution is constant, driven by the ever-growing demands for simplicity, scalability, and operational efficiency. Segment Routing (SR) emerges as a promising solution to address the shortcomings of traditional MPLS protocols like LDP/RSVP-TE. But the question here is why the shift? And what exactly is Segment Routing? Why Segment Routing? Traditional […]
