OSPF

OSPF is like a traffic director for the internet. Imagine a city with many roads - OSPF helps routers (the traffic directors) figure out the best paths for data to travel from one place to another. It’s like a smart GPS for computers, making sure information takes the shortest and fastest routes. OSPF routers talk to each other, share maps of the internet, and decide the best ways to send data. It’s a cool system that keeps the internet running smoothly!

SR-MPLS

Segment Routing with MPLS Labels (SR-MPLS) is a major improvement over the traditional MPLS control plane (LDP or RSVP-TE). Instead of running two protocols (a routing protocol and a signaling protocol), SR-MPLS adds segment information to the IS-IS or OSPF topology database, avoiding the pesky IGP/LDP synchronization issues we’ve been fighting for decades.

The MPLS labels (Segment Identifiers) assigned to nodes, adjacencies, or prefixes can be used to transport data across the network (similar to traditional MPLS core), to establish traffic engineering tunnels, or to implement topology-independent loop-free alternate paths for fast failover.

AI

Artificial Intelligence (AI) and Machine Learning (ML) are the next big hype in networking following Software-Defined Everything and Intent-Based Everything. Like with the previous hype bubbles it’s worth figuring out

  • How much of the hype is real (TL&DR: not much)?
  • Whether the technology is ready to be used in production networks (TL&DR: some of it)
  • How you could use the technology to make your life easier

How Real Is It?

Like with the previous hype tsunamis, I’ll do my best to help you figure out the answers to the above questions with a hefty dose of skepticism and snark1, starting with:
