Zoidcom
From GDWiki
Zoidcom is a high-level, UDP based networking library for the C++ language providing features for automatic replication of gameobjects and synchronization of their states over a network connection in a highly bandwidth efficient manner. This is achieved by multiplexing and demultiplexing object information from and into bitstreams, which make it easily possible to avoid sending redundant data. Bools only take one single bit, integers and floats are stripped down to as many bits as needed.
A great deal of the tedious work that appears when attempting to develop an efficient network protocol is handled by Zoidcom, e.g. deciding when to send which data to which client, how to get it efficiently and reliably through the line, what to do when data gets lost and a lot more.
