The '''Fast Local Internet Protocol''' ('''FLIP''') is a suite of [[Internet protocol suite|internet protocols]], conceived for [[distributed computing |distributed applications]]. FLIP was designed at the [[Vrije Universiteit Amsterdam]] to support [[remote procedure call]]ing in the [[Amoeba (operating system)|Amoeba]] [[distributed operating system]].<ref name="FLIP">[[M.

Syst. 11, 1 (Feb. 1993), 73–106. https://doi.org/10.1145/151250.151253</ref>

In the [[OSI model]], FLIP occupies [[Network layer|layer 3]], thus replacing [[Internet Protocol|IP]], but it also obviates the need for a transport-level protocol like [[Transmission Control Protocol|TCP]].

FLIP is a connectionless protocol designed to support transparency (with respect to the underlying network layers of the OSI model: 2. data link and 1. physical), group communication, secure communication and easy network management. The following FLIP properties helps to achieve the efficiency requirements:

*FLIP identifies entities called network service access points (NSAPs).
