That is a pretty big task for a student project, at least if you
are aiming at a working HSS - or is the goal to write an _entire_
Fortunately, you don't also have to write a TCP stack. :)
The gen_tcp module will do quite nicely. However, if you want to be
true to the IMS specification, it is really SCTP you should be
looking at. The SCTP support in OTP is not quite ready for this
sort of thing, unless I've missed some important development, but
given that you're in a student project, it might be good enough
for your purposes.
You may want to take a sneak peek at this:
It doesn't have Diameter support.
