In this exercise, you will design a protocol which determines how a packet of data will be sent from one node in a network to another. Your protocol will consist of a set of rules which each node will apply when it receives the data packet. The aim is to get the data packet from its starting node in the network to its intended endpoint. There are two main criteria your protocol must adhere to:

Each node must have all of the instructions equally applicable to it.
No node can know anything other than who they directly interface with. In other words, nodes can only know about the nodes that are connected to them.
