Re: [lwip-users] Need to Know more about tcp and it's concepts

[Sergio R. Caprile]

You should start by learning communications and networking, there are
several books outthere, I'm fond of Mr. Tanenbaum, get a copy of
Computer Networks.
For TCP/IP itself, read Douglas Comer or Stallings.

However, what you mention in your mail are lwIP functions.
Apples and oranges
Once you know what a connection oriented protocol is, and get an idea of
what a machine to serve that protocol should do, try to think how to
make it work in an event driven framework with a small overhead. That is
the lwIP raw api.
You can read an intro to how to use these functions in the wiki.
However, the text assumes you know TCP (it is qiute difficult to do
rocket science without knowing about rockets or science, the same
applies to networking with microcontrollers).
