I have a problem of simulating multiple priority queues. In Linux, normally, there is a socket buffer corresponding to each connection. Data streaming into each socket buffer is encapsulated into packets which obtain TCP headers and IP headers. Throughout this processing, the packet streams corresponding to each connection is kept separate. Finally, there is a single ??priority queue?, into which all streams feed. All streams that have data ready to send take equal turns draining into the priority queue. (FAIR) There is another possible approach. Instead of a single priority queue (transmit queue), there are 16 priority queues. These are called bands and they range in number from 0 to 15, where band 15 has lowest priority and band 0 has highest priority. All the connections of i priority feed fairly into the i th priority queue. (SPRT). I have attached a figure describing these two approaches. My question is, is it possible to simulate both FAIR and SPRT in ns-2. Could you guys give me some hints how to do that? I really appreciate any suggestion.

[ns] Packet dropping with multiple agents
Hi all, I have two nodes with different source agents for UDP but sink is same for the two. In the simulation most of the packets get dropped. I have tried changing the node positions making them sufficiently close so that transmission range couldn't be problem but still getting most of packets dropped. Please let me know if anybody has the solution. Thanks Arslan
[ns] installing ns in linux
hi i worked with ns-2 under cygwin and now decide to installing linux an after that ns-2 under linux. because xgraph and nam didnt work under cygwin. now i need help for installing linux which version is good for ns?

[ns] Ns2 error : Makefile errors
Hi, I am new to the ns2 community. I was implementing the Mark Greis implemetation of the new ping protocol for my ns-2.33 on Ubuntu 8.04. Everything from creating a new header file, C++ code and relevant changes to the ns source files have been done. The tutorial says *Remember that you have to do a 'make depend' before you do the 'make', otherwise these two files might not be recompiled *where we have added new packet information to the packet.h file. Now I want to ask that whether I should run a makedepend for packet.h to recompile it ( in that case it is giving me an error that no Makefile present) , or to run a makedepend on ping.h and ping.cc ( in case of that it gives me warning like this for all header files included : *makedepend: warning: ping.cc (reading ping.h, line 51): cannot find include file packet.h not in packet.h not in packet.h not in /usr/include/packet.h *) Ignoring this warning, when I type in make it says : *Makefile:361: *** missing separator. Stop.* I am stuck . Kindly help Regards, Mayank Sharma
