Help!!!: TCP code size/memory usage / footprint

bichettelinux · 07-13-2003, 05:04 PM

Hi all,

I need your help.

Do you have an idea about how much the TCP footprint ( memory usage and code size ) is for typical linix operating systems?

If you have any ballpark figure, it would be great!!!
If you know of any specific reference, that will be the best!!!

Thanks in advance.

How big is TCP's overhead? I don't understand what you're asking, please rephrase + more info.

I would like to know how much memory is neccessary for executing tcp stack. If we measure how much system resources are used for this connection, then we can identify how efficient this protocol is especially for memory usage perspective.

And also, a code size can be another criteria to measure this efficiency. Currently, ipv4.o file contains various protocol stacks such as udp, tcp, icmp, ip. I would like to extract the size of only tcp so that I can evaluate their occupancy in memory.

Thank you for your reply.

ah, I understand. Since you're asking this question, I'd assume you're a programmer of some sort. There probably aren't very many people that could answer this question for you, but here's how you would find out on your own..

Get a copy of the Kernel source from ftp.us.kernel.org. The directory you'll concern yourself with is linux/net/ipv4 . In that directory you'll find tcp.o and all the other files nessicary for ipv4 to function including the source code (which is in C).

Hope this helps.
