Hi Rajya,
You really must provide more information about what you need and what you are trying to achieve.
What network protocols in particular? What programming language are you using, and what are your skills like in this language?
Have you tried Google? There are also many, many textbooks for this kind of thing. An example is Unix Network Programming by Stevens (
