You might find the books "C++ Network Programming, Volume I: Mastering Complexity with ACE and Patterns"[0] and "C++ Network Programming, Volume 2: Systematic Reuse with ACE and Frameworks"[1] useful. They talk about implementation of the "Adaptive Communication Environment" [2] which is an open-source project for network programming. Also, as nextos mentioned below, the "Pattern-Oriented Software Architecture" series.
