Mitigating Broadcast Propagation in Redundant BMA Networks Using Layer 3 Uplinks

The purpose of redundancy in computer networks is to increase the robustness and resilience of the network. Deploying multiple paths to network devices or redundant devices could accomplish this purpose. It would also increase the complexity and chances of having a broadcast storm within the network due to potential loops from multiple paths. The Spanning-Tree Protocol was developed to uphold these desired network features and solve the loop problem. Layer 3 switches have facilitated the deployment of layer 3 links between specific switches which was only possible with layer 2 links. This paper explores alter-native layer 3 (Open Shortest Path First and Enhanced Interior Gateway Protocol) protocols that could efficiently replace the spanning-tree protocol in Broadcast Multi-Access Networks. An analysis of the performance of these protocols was made in com-parison to spanning-tree in their ability to uphold redundancy, resilience and robustness. Experimental tests were implemented for User Datagram Protocol and Transmission Control Protocol transmissions. The results showed that both layer 3 protocols can efficiently replace spanning-tree in Broadcast Multi-Access Networks.
