Question: "Construct a map of the configuration of gateways and routers linking the universities in Australia. The map should include nodes with the domain names of the gateways/routers as well as their IP address. The lines linking the nodes should indicate the round trip time required to traverse them."
Here is a schematic map from http://www.parnet.edu.au showing the schematic route of all the lines connecting all the universities of Western Australia Australia. It shows all the nodes on each state that acts as a gateway to the next node.
Here is the schematic map from http://www.parnet.edu.aushowing the routes of all lines connecting to a optus backbone of all the universities in Australia.
Here are some examples of schematic diagrams of how a packet reaches its destination from all the different parts of the networks it has to access.
The following maps below are shows selected Universities in Australia in detail with the main routers that a packet trace route goes through and the IP address and round trip times it takes to go from source Murdoch to destination Universities. group by each states.
