thin network communication layer on top of UDP
ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol). The primary feature it provides is optional reliable, in-order delivery of packets.
ENet is NOT intended to be a general purpose high level networking library that handles authentication, lobbying, server discovery, compression, encryption and other high level, often application level or dependent tasks.
