Hello everybody, sorry if I come again with the same question, but I am in fact stuck. Let's suppose we want to multiplex N small packets (each one with a certAin UDP header and its corresponding data) into a UDP bigger one. Is any agent of this kind already available in ns2? Any tip would be greatly appreciated. Thank you very much in advance for your help. _________________________________________________________________ Busca desde cualquier página Web con una protección excepcional.
