How does the Border Gateway Protocol (BGP) work, and what is its role in internet routing and network connectivity?
In the intricate web of the modern internet, where data flows seamlessly across the globe, a hidden but vital player ensures that digital packets reach their intended destinations efficiently. This unsung hero is the Border Gateway Protocol, or BGP. BGP is the linchpin of internet routing, responsible for determining the paths data takes as it traverses the vast network of interconnected routers and networks. In this exploration, we will delve into the inner workings of BGP, understanding how it functions both as an inter-domain routing protocol and a path vector routing algorithm. Furthermore, we will uncover the pivotal role BGP plays in shaping the landscape of internet connectivity, from its role in routing data between Autonomous Systems (ASes) to its ability to facilitate traffic engineering, policy-based routing, and network redundancy. So, let's embark on a journey to demystify the world of BGP and unveil its significance in the digital age.
