Good Questions about Network Simulation.. and Trace File

This is a comment from my old blog, which I seldom update now.. its a good question..  I dont answer the question though...   :( 


1.How to find out the number of nodes in the network from the trace file? Also can u give any examples that would help please??

2.How to discover the “visible network topology” from the trace file? Give examples pleeeeeeeease.

3.Which parameters of the event descriptor in the trace file can be used for calculation of the throughput on the link? examples would really help

4. Which parameters of the event descriptor in the trace file can be used for calculation of the throughput on the end-to-end route? any examples??.

5.What typical functions are needed in order to extract useful data from trace files (think in terms of getting values from some text columns, sorting of strings, etc.)? Can u please make a pseudo-code for the postprocessing algorithm. Aslo do u know Which standard Unix utilities may help to extract necessary data from the trace files and process them? Give examples of sequences pleaseeeeeeeee (i.e. which to run first, which is next, etc.).


Good questions..  but what are the answers.....
