Example 4 is the same OTcl script as the one in the "Simple Simulation Example" section with a few lines added to open a trace file and write traces to it. If you can imagine a network in which there are only two nodes (say, two computers, for instance), you can easily picture a point-to-point network. It is clearly evident from the diagram that this Type of Topology works by using a central device to which all other Nodes like Clients, Servers and other Network Nodes are connected. The duplex links between n0 and n2, and n1 and n2 have 2 Mbps of bandwidth and 10 ms of delay. each node has not more than 2 children? - what kind of data is stored in the tree? - is yours a search tree, i. In the world of networking, you'll often hear the word "topology.
