The NeEM library provides an implementation of epidemic multicast (also called probabilistic or gossip-based) in wide-area networks by using multiple TCP/IP connections in a non-blocking fashion. Epidemic multicast protocols achieve stable high throughput regardless of node and network faults and scale to very large numbers of participants. Implementation is based on Java 5 and takes advantage of NIO. The goal of this implementation is to be small, self-contained, and practical.


This release introduces logging and the ability to bind to and advertise specific addresses. Some dead code was removed in the network layer. A UPnP-based NAT traversal sample application was added.
