Hi all, I'm new to NS now. My group tries to simulate the Narada protocol - an End system multicast protocol which works on the application layer. I wonder where I could begin? I think that with End system multicast architecture, we need not to develop a new underlying protocol, we just need to implement the overlay network and its application-level communication protocol only, with the underlying network protocol (TCP/IP) support. I think that we should derive a new Application in the ns class hierarchy. I'm not sure whether this is an accurate start point. Anyone can help? Thanks.
