The Fast Local Internet Protocol (FLIP) is a communication protocol for LAN and WAN, conceived for distributed applications. FLIP was designed at the Vrije Universiteit Amsterdam to support remote procedure call (RPC) in the Amoeba distributed operating system.
Comparison to TCP/IP
In the OSI model, FLIP occupies the network layer (3), thus replacing IP, but it also obviates the need for a transport layer (4) protocol like TCP.
