Routing Protocols and Internet Architecture
The module on Routing Protocols and Internet Architecture delves into the essential components and operations of network routing as a critical aspect of modern networking. It systematically outlines Link-State and Distance-Vector routing protocols, highlighting their respective mechanisms, benefits, and challenges. Furthermore, it explores the internet's hierarchical structure, clarifying the distinct roles of end-user organizations, Internet Service Providers (ISPs), and the need for inter-domain and intra-domain routing protocols like OSPF and BGP for effective traffic management.

What we have learnt
- Routing protocols are critical for directing data packets from source to destination across interconnected networks.
- Link-State protocols provide routers with a complete view of the network topology, enabling efficient and rapid path calculation.
- Distance-Vector protocols rely on neighboring routers to make routing decisions, which can lead to slower convergence and potential routing loops.
Key Concepts
- -- Routing Protocols
- Protocols that determine the paths for data packets across networks, facilitating the discovery of optimal routing paths and the sharing of connectivity information.
- -- LinkState Routing
- A routing protocol paradigm where each router maintains a complete map of the network topology, allowing for independent calculation of optimal paths.
- -- DistanceVector Routing
- A routing protocol where routers share routing information with direct neighbors, relying on periodic updates to maintain routing tables.
- -- OSPF (Open Shortest Path First)
- A widely used Link-State routing protocol for intra-domain routing that supports hierarchical routing and rapid convergence.
- -- BGP (Border Gateway Protocol)
- The primary routing protocol used for inter-domain routing across the internet, focusing on policy enforcement and path vector exchange.
