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.
TIXI is a fast and simple XML interface library for applications written in C, C++, Fortran, Java, and Python. Although simplified and somewhat restricted compared to a fully-fledged XML processing library, it can create documents, create and delete nodes, and add and remove element attributes. Routines for reading and writing text nodes and nodes holding integer and floating point numbers are included, along with routines that process aggregates of these simple types for the processing of geometric data, multidimensional arrays, or arrays of vectors.
The Mirror C++ reflection library provides both compile-time and run-time meta-data describing common C++ program constructs like namespaces, types, enumerations, classes, their base classes and member variables, constructors, etc. and provides generic interfaces for their introspection. It also provides several high-level utilities based on the reflected meta-data like a factory generator, which generates, at compile-time, implementations of object factories which can create instances of arbitrary 'reflectable' type.
