Very Computer

Guys,

I'm new to programming and I have a few questions. The reason I'm learning C
is that I'm interested in network programming. I have a network engineering
background with some Unix administration. I've had a chance to look at at
several implementations of the TCP/IP stack.

Where do programmers get the source code for network protocols? TCP/IP ,
OSPF, BGP?

There is an IBM red book on it. There you can get detailled information.
Look into kernel sources for implementation.

Adib.

"Source code"?

Programmers get the specifications for the various protocols from the
IETF's RFC database. There are RFCs defining each of the protocols, in
detail; the RFCs are _the_ definition of the protocol.

Programmers _write_ the source code to implement the protocols.
Frequently, they use reference manuals for guidance wrt the building of
interfaces, etc. As one poster suggested, the IBM RedBook collection
contains one such reference manual. However it isn't the _only_
referencec manual; there are many manuals available, from Stevens
"TCP/IP Illustrated" and "Unix Network Programming" on to manuals
documenting the MSWindows "WINSOCK" API.

Where can _you_ get the source code? /usr/src/linux/net/ipv4/*.c and
other places in the Linux source code tree.

Most programmers don't bother with source code for network
protocols. They just use the stacks provided by the OS.
