1. Background

  To help others to understand protocols, showing the operations of each protocol and comparisons between them in several situations were necessary. For stop-n-wait protocol, I could simulate it by changing some parameters of TCP. For the slow start, I used TCP itself, but sliding window was different. It was not possible to simulate it using TCP. However, I changed a little C++ codes in TCP and could simulate sliding window protocols. Followings are the changed codes and added codes.

2. Changes of existing library :

    1) tcp.h
    2) tcp-sink.h

3. Added file.

    1) sliding.cc
    2) sliding-sink.cc

4. Added files for Validation Test.

    1) test-all-sliding-window
    2) test-suite-sliding-window.tcl
    3) sliding-normal.Z  : under "test-output-sliding-window" directory
    4) sliding-loss.Z       : under "test-output-sliding-window" directory

5. Original TCP and TCP-SINK files.

    1) tcp.cc
    2) tcp-sink.cc

All of the examples written in tcl exist in /usr/src/mash/repository/vint/nam-1/edu
