ACE Programmer’s Guide, The [PDF ebook] 
Practical Design Patterns for Network and Systems Programming, Portable Documents

The ADAPTIVE Communication Environment (ACE) is an open-source software toolkit created to solve network programming challenges. Written in C++, with the help of 30 core developers and 1, 700 contributors, this portable middleware has evolved to encapsulate and augment a wide range of native OS capabilities essential to support performance-driven software systems. The ACE Programmer’s Guide is a practical, hands-on guide to ACE for C++ programmers building networked applications and next-generation middleware. The book first introduces ACE to beginners. It then explains how you can tap design patterns, frameworks, and ACE to produce effective, easily maintained software systems with less time and effort. The book features discussions of programming aids, interprocess communication (IPC) issues, process and thread management, shared memory, the ACE Service Configurator framework, timer management classes, the ACE Naming Service, and more.
