Sockets tcp/ip communication library
C++ Sockets Library
This is a GPL licensed C++ class library wrapping the berkeley sockets C API, and therefore works on most unixes and also win32. The library is in use in a number of real world applications, both commercial and open source.
Features include, but are not limited to,SSL support,IPv6 support,tcp and udp sockets, sctp sockets, http protocol, highly customizable error handling. Testing has been done on Linux and Windows 2000, and to some part on Solaris and Mac OS X.

ACE
TheADAPTIVE Communication Environment (ACE) is a freely available, open-source object-oriented (OO) framework that implements many core patterns forconcurrent communication software. ACE provides a rich set of reusable C++ wrapper facades and framework components that perform common communication software tasksacross a range of OS platforms. The communication software tasks provided by ACE include event demultiplexing and event handler dispatching, signal handling, service initialization, interprocess communication, shared memory management, message routing, dynamic (re)configuration of distributed services, concurrent execution and synchronization.
ACE is targeted for developers of high-performance andreal-time communication services and applications. It simplifies the development of OO network applications and services that utilize interprocess communication, event demultiplexing, explicit dynamic linking, and concurrency. In addition, ACEautomates system configuration and reconfiguration by dynamically linking services into applications at run-time and executing these services in one or more processes or threads.

libevent – an event notification library
The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts.
libevent is meant toreplace the event loop found in event driven network servers. An application just needs to call event_dispatch() and then add or remove events dynamically without having to change the event loop.
Libevent allows for portable application development and provides the most scalable event notification mechanism available on an operating system. Libevent can also be used formulti-threaded applications, either by isolating each event_base so that only a single thread accesses it, or by locked access to a single shared event_base. Libevent should compile on Linux, *BSD, Mac OS X, Solaris, Windows, and more.
Libevent additionally provides a sophisticated framework for buffered network IO, with support for sockets, filters, rate-limiting, SSL, zero-copy file transmission, and IOCP. Libevent includes support for several useful protocols, including DNS, HTTP, and a minimal RPC framework.

Web Server Framework
light WebServer
lighttpd
Security, speed, compliance, andflexibility — all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized forhigh performance environments. With asmall memory footprint compared to other web-servers,effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems.
mongoose(shttpd)
Mongoose is an easy to use web server. It can be embedded into existing application to provide a web interface to it.
Features：
l Crossplatform – works on Windows, MacOS and most flavors of UNIX
l CGI, SSL, SSI, Digest (MD5) authorization, resumed download, aliases
l IP-based ACL, Windows service, GET, POST, HEAD, PUT, DELETE methods
l Small footprint: executable size is 40 kB on Linux 2.6 i386 system, 60 kB on Windows system
l Embeddable with simple and clean API. Source is in single .c file to make things easy
thttpd
thttpd is a simple, small, portable, fast, and secure HTTP server.
Simple:
It handles only the minimum necessary to implement HTTP/1.1. Well, maybe a little more than the minimum.
Small:
See the comparison chart. It also has a very small run-time size, since it does not fork and is very careful about memory allocation.
Portable:
It compiles cleanly on most any Unix-like OS, specifically including FreeBSD, SunOS 4, Solaris 2, BSD/OS, Linux, OSF.
Fast:
In typical use it’s about as fast as the best full-featured servers (Apache, NCSA, Netscape). Under extreme load it’s much faster.
Secure:
It goes to great lengths to protect the web server machine against attacks and breakins from other sites.
It also has one extremely useful feature (URL-traffic-based throttling) that no other server currently has. Plus, it supports IPv6 out of the box, no patching required.

IM WebServer
Jabber
Jabber isInstant Messaging(IM) server written in pure C language,which is theorigin ofXMPP. It is based on XMPP(eXtensible Messaging and Presence Protocol) expressed in XML.With Jabber/XMPP, differences between the IM are overcomed. It allows you to communicate between MSN,Yahoo, and etc.
Instant messaging between theGoogle Talk servers and its clients uses an open protocol,XMPP, allowing users of other XMPP/Jabber clients to communicate with Google Talk users. That is any client that supports Jabber/XMPP can connect to the Google Talk service.Refer toGoogle Talk and MSN via Jabber together in iChat.
