JS-Collider is an event-driven Java network NIO framework. It is designed to provide maximum performance and scalability for applications having not too many connections but significant amounts of network traffic (both incoming and outgoing). Performance and scalability are achieved via lock free algorithms and atomic states usage. It supports UDP (with multicast) as well. One of the implementation points is to avoid unsafe cheating; it should work the same way on all JVMs (Java 1.7). It supports shared memory IPC.
