Technical Networking Army

  Preface: When two big ISPs merge like Vodafone and Idea in India, ensuring global Internet reachability is a technical must. Both operators have separate Autonomous Systems (ASNs), IP address blocks, backbones, peering and transit agreements. Before the merge, engineers need to plan the consolidation of ASNs, harmonize BGP routing policies and integrate IP address resources to avoid route leaks and blackholes. All upstream and peering relationships need to be reviewed and updated to ensure customer prefixes from both legacy networks are globally reachable. In the Vodafone Idea merger scenario this means merging their routing domains, advertising prefixes consistently across international exchanges and validating end to end connectivity to ensure seamless Internet services to millions of customers during and after the merge. Prerequisite taken before ISP merger: Kindly follow below steps as a prerequisite before ISP merger -- AS strategy Do: Keep both ASNs for now ...

  Preface: As streaming becomes a part of our daily lives, the tech behind delivering high-quality content to millions of people worldwide has gotten incredibly advanced — and invisible. One of the most innovative architectures powering this seamless experience is the Cloud-Based Headend (CBH) system, a modern evolution that moves traditional content processing and distribution workflows to the cloud. Companies like Netflix have taken this to the next level using CBH-like architectures combined with edge caching to ensure their massive libraries of shows and movies are always just a click away, no matter where you are. But even this cutting-edge system can have issues, especially when it comes to network latency — the hidden villain that can turn a perfectly planned movie night into a buffering wheel and pixelated scene fest. Imagine a user in Virginia trying to watch a new series on Netflix and getting long loading times and constant interruptions because the local edge cache ...
