I notice we don't have a buffer concept in any of our net/socket writeups on the wiki. I think that's a big omission. I also wonder if the abstraction doesn't already exist --> std::basic_streambuf. Let the socket class write into the streambuf and then you can trivially wrap a stream around it to do sophisticated i/o if you wish -- or simply pull out the raw chars....
A buffer concept is absolutely essential for TCP. Without it you will run into delays with Nagle, delayed ack and slow start all combine-ing. Yuk! Streambuf makes sense for the iostream concept. For lower layers the buffer concept needs to be a model of contiguous container. Iterator type can only be guessed at because I don't know what goes on inside the 'C' socket lib or the kernel but first guess would be forward iterator. /ikh
