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.…

ending of net neutrality. Net neutrality is currently in place and denies internet providers from being able to change the speed of service for the internet, overall it allows for a very free and open internet where all websites, big or small, gain access to the same speeds for providing content to users.
