Re: [ns] question on installation NS-2.29 on Linux Ubuntu

2007-04-13 Thread Arturo Servin
I had the same problems in Ubuntu 6.10 and ns-2-31. I had to compile with gcc and g++ 4.0 instead of 4.1 (default in my distro). There are a couple of urls documenting this and how to install ns in ubuntu. http://thesandeep.wordpress.com/2006/12/02/installing-ns2-on-ubuntu-dapper-lts/

Hi, Some time ago somebody sent this post to ns-users. I am trying to build a flow table. Each node send data (UDP or TCP) to other nodes. The simulation now is very small, just 5 or 6 nodes and I want to make a file with the information of flows over time. Basically what it is said in the

I do not know if carrying a bandwidth value inside the flow is the best solution. Bandwidth as I see is data_transmitted/time. And time is relative, are you going to measure the bandwidth in the last second, the last minute, the last hour? So that why I think is not the best way. I would

It would depend of what you want to do. I am using UDP and CBR in a manual topology that I generated. There are some tools to automatic generate a big number of nodes but I have not tested yet. Now my attacks are confined to a small network. -as brij wrote: Dear all please guide me to

I remember something similar with Frame Relay and mostly with ATM, which in deed had its own routing protocol PNNI. I do not know about IEEE 802.11s but with ATM you need to switch the cells independently from the L3 protocol (then it came MPLS and we forgot about ATM), I imagine that

If you are working with your code in TCL may be you can make a map Node_ID (from ns) to an IP address in your TCL script. If you are working in C++ you can do what Sidney proposes. Either way you have a way to do it, may be not trivial but definitely possible. -as

You have to include your code (I am not sure but I think that you should do it in the same path were the rest of the ns code is) and to modify the make files in order to compile your code. Check the own ns makefiles as an example, they will give you a hint of what to include. -as
