I am trying to implement the above multicast protocol using ns2, but i am unable to find correct source on how to build the protocol.

I read through the documentation, all they said about was Centralised Multicast, Dense Mode, Shared Tree Mode and Bidirectional Shared Mode, but i have no idea as to how to implement DVMRP.

  • DV : ns2 is old, not much saved, e.g. NSBench0.9.jar http://www.cas.mcmaster.ca/~cs4cc3/labs/4cc04lb2.pdf .... Edited "test.tcl" / DVMRP_test.tcl → https://drive.google.com/file/d/1GE_60q_8yvr91qG_UmrrgV1FKVBAUaoz/view?usp=share_link → not working! ......... **DV+mcast-ex-7.tar.xz** https://drive.google.com/file/d/199Z1q-jFYRC1yQPjeEHT-IGqKT0AY0H-/view?usp=share_link .......

  • @KnudLarsen thank you, but how can i use the patch file ?? I want to compare these two protocols, how can i do that? on what basis should i compare – Santosh Kumar Doodala Nov 14 '22 at 03:09
  • @KnudLarsen i went through a video https://www.youtube.com/watch?v=st50WO2hTQA&t=1330s , in this he has talked about 5 files,, and then i saw cas.mcmaster.ca/~cs4cc3/labs/4cc04lb2.pdf , this has the code for dvmrp. I mean what is the difference netween them? What is happening in these two? I am really sorry if my doubts seems silly, but is really bugging me – Santosh Kumar Doodala Nov 14 '22 at 04:16
  • @KnudLarsen I have one more doubt I read through the documentation, in that Centralised Multicast, Dense Mode, Shared Tree Mode and Bidirectional Shared Mode were present. what are they ?? protocol or something else? – Santosh Kumar Doodala Nov 14 '22 at 04:19
  • About http://www.cas.mcmaster.ca/~cs4cc3/labs/4cc04lb2.pdf : The files are no more, ns2 officially unsupported for 7 years. ..... About "two patches" : I mentioned **one** patch : `cd ns-allinone-2.35/ && patch -p0 < ospf_ns235.patch` ........ ns2 INFO https://docs.google.com/document/d/1dbrFE8CDMNbE5Kmq4duZl6bUTP7PXdVps9AGvzVi0gM/edit?usp=sharing – Knud Larsen Nov 14 '22 at 08:32
  • @KnudLarsen how to use the patch and what is the use of using the patch file?? – Santosh Kumar Doodala Nov 15 '22 at 02:48
  • Please read (again) https://docs.google.com/document/d/1dbrFE8CDMNbE5Kmq4duZl6bUTP7PXdVps9AGvzVi0gM/edit?usp=sharing , page 1-2 to watch "ns-allinone-2.35/ → patch -p0 < ospf_ns235.patch" .... Requirements: `sudo apt update && sudo apt install g++ g++-4.8 autoconf libtool libxmu-dev` ......... The patch is a readable text file ... all "added items" are marked + . – Knud Larsen Nov 15 '22 at 20:27
