    Nt1310 Unit 3 Assignment 1 Data Analysis

    The two source nodes, 1 and 2, have messages A and B that need to be transmitted to the two destination/sink nodes, 5 and 6, which need both A and B to be delivered. Each edge in this network can only carry a single value. If nodes could only route/retransmit, then the central link would only be able to carry message A or message B, but not both of them at the same time. Assuming we sent message A through the center, then node 5 would receive message A twice and would never receive message B. The same problem would occur at node 6 if we sent message B through the center node, with node 6 never being able to receive message A. We can immediately see here that routing would be insufficient since no routing scheme can simultaneously transmit A and B to both sink nodes.…
