Reliable Data Transfer Protocol implementation in C++ using modified ALTERNATING BIT AND GO-BACK-N NETWORK EMULATOR FROM VERSION 1.1 of J.F.Kurose as an assignment of Computer Networking Lab in Level-3, Term-2 of BUET.

In this assignment sender and receiver implemented for two versions of RDT3.0 are implemented for only simplex data transfer:

  • Alternating-bit protocol (ABP)
  • Go-Back-N (GBN) with finite sequence numbers [0,7].

Additional Implementation:

  • separate timers used for each packet in sender's window.
  • another modified version of go-back-n is implemented which sends cumulative ack after certain timeout unlike normal gbn.

Detailed specifications can be found at "offline_specification.pdf" in folder "Assignment-Specifications".

Simulation:

  • compile and run rdt_abp.cpp to simulate Alternating-bit protocol.
  • compile and run rdt_gbn.cpp to simulate Go-Back-N protocol.
  • compile and run rdt_gbn_cumulative_ack.cpp to simulate Go-Back-N protocol with modified receiver.

This repo has been worked in CLion project and that's why CMakeLists.txt exists here.
