Networks, and the Internet in particular, have experienced exponential growth , becoming one of the largest engineering systems ever constructed. Management of this large system is of critical importance, and challenging at the same time. Measurements and models based on these measurements are integral components to understand network behavior and provide basis for better management.

Syllabus
  • Internet Traffic Analysis: self-similarity and long-range dependency
  • Packet Loss/Delay Characterization: statistical models
  • Packet Size/File size: statistical models
  • implement our TCP algorithm in ns2 simulator and compare with e.g: vegas algorithm
Assignments
  • Assume a conntected graph and write adjacency matrix and adjacency list for it , then show BFS,DFS,DijKstra algorithm on it. Show the Strong and Weak tie and a Bridge on the graph. Find Time and Space order for finding an edge.
  • Prove Long Range Dependence(LRD) in network traffic(Problem1)
  • Download a (Traffic Data Files), Model distribution of arrival Packets by pareto distribution and generate your own data dump file and compare with orginal traffic data file.
  • Run three os in virtual machine, Bulid a lan between two pair of them, connect two Lans by a router , config it , and generate a data flow from one client to another one. and capture the traffic.
  • Run three os in virtual machine,(one unix base, and the others be XP), set linux as a router , between the other machines , Implement your tcp algorithm and transfer a file from one to another machine and compare your algorithm with real tcp algorithm.
  • Implement your tcp algorithm using c++ and use your own tcp algorithm in ns2
  • Implement a traffic generator which generate traffic packets from a real traffic dump file. Calculate File size distribution and offer a distribution function to simulate a real traffic file size
