spdylay is an experimental implementation of Google's SPDY protocol in C. It provides a SPDY framing layer implementation. It does not perform any I/O operations. When the library needs them, it calls the callback functions provided by the application. It also does not include any event polling mechanism, so the application can freely choose the way of handling events. This library code does not depend on any particular SSL library (except for example programs that depend on OpenSSL 1.0.1 or later).
The ROHC library provides an easy and robust way for applications to reduce their bandwidth usage on network links with limited capacity or expensive costs. Headers of network packets are compressed with the ROHC protocol and algorithms. The ROHC protocol is very efficient for compressing VoIP streams which use RTP as a transport protocol. ROHC is also suitable for compressing IP-only (IPv4 or IPv6) flows, UDP flows, and many others.
Libporty provides a higher level API for some commonly used library functions such as sockets, date/time, file system access, background processes, and asynchronous DNS resolving. Libporty is configured using scconfig and the API is guaranteed to work the same way on all supported systems. An application that exclusively uses the libporty API will not require autotools/scconfig for porting. Libporty has been tested on Linux, Windows, Mac OS X, multiple BSD variants, Minix, OpenSolaris, and some ancient Unix systems.
