Comparative Analysis of Bellman-Ford and Dijkstra Algorithms in Software Defined Networking

One of the key functions of the internet is packet routing of data. A routing protocol outlines the channel of communication between routers that is utilized to connect networks. Numerous routing protocols, including OSPF and RIP are used on the internet. Each protocol has a unique packet routing function. Bellman-Ford and Dijkstra are SDN routing algorithms; the former accommodates negative weights, suiting more complex network topologies, while the latter works efficiently for non-negative weights, ensuring faster convergence. RIP’s reliance on the Bellman-Ford algorithm leads to slower convergence and potential routing cycles in bigger networks. OSPF, while stronger with Dijkstra’s algorithm, can introduce high communication overhead due to maintaining complete network topology data. Bellman-Ford employs a dynamic programming approach, handling diverse network conditions, whereas Dijkstra’s greedy strategy excels in finding the shortest path in positively weighted networks. respectively.
