Validate the ns-3 implementation of TCP Low Priority in DCE

TITLE:

Validate the ns-3 implementation of TCP Low Priority in DCE

This Validating-the-TCP-LP-implementation-in-ns-3 repository is a joint Computer Networks project.

Description

TCP Low Priority (TCP-LP) is a Less than Best Effort TCP. This category of TCPs are used to ensure that bandwidth hungry large flows do not saturate the bandwidth and starve small delay sensitive flows. In this project, the aim is to validate ns-3 TCP-LP implementation by comparing the results obtained from it to those obtained by simulating Linux TCP-LP.

Getting queue size zero for router-1 on ns3 stack.

After running dumbbell topology on ns3 stack for TCP-LP, getting queue size as 0. PRR is also set. Here is the graph.

Problem in running dce code in linux stack.

I am trying to run dce on linux stack using this command.
./waf --run "dce-iperf --stack=linux"

But I am getting this error. How to solve this error.

Command ['/Desktop/dce/dce-linux-dev/source/ns-3-dce/build/bin/dce-iperf', '--stack=linux'] terminated with signal SIGSEGV. Run it under a debugger to get more information (./waf --run --command-template="gdb --args %s ").
