[ns] TCP's packet size does not vary with the FTP's packetsize.

Dear all, I am using simple FTP over TCP. In ns, from the application layer (ftp) Though I send small packets, (eg. 100 bytes using '$ftp_($i) send 100' ), TCP's packet size remains fixed equal to 1000. What is the reason? How to change it. I tried to study the tcp.cc's send and sendmsg()

Re: [ns] Problem with Scheduler

Hi all, I have a little problem with the Scheduler. I schedule some packets in my program Scheduler::instance().schedule(target_, p, (100/tcf_time)); but when i try to cancel some of them from the queue not to be sent Scheduler::instance().cancel(p); drop(p); It doesn't work. I read

Re: [ns] TCP's packet size does not vary with the FTP's packetsize.

Hi! It is a fundamental property of TCP to set the packet (segment) size of its own. This is set with respect to path MTU, and various buffers. Thus, the size of the incoming FTP packets will not impact the outgoing segment size, since TCP is a byte-oriented protocol. However, ns-2 is not a
