Fast Local Internet Protocol

The Fast Local Internet Protocol (FLIP) is a suite of internet protocols, which provide Security transparency, security and network management. FLIP was designed at the Vrije Universiteit Amsterdam to support remote procedure calling in the Amoeba distributed operating system.[1] In the OSI model, FLIP occupies layer 3, thus replacing IP, but it also obviates the need for a transport-level protocol like TCP.

FLIP is a connectionless protocol designed to support transparency, 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).
  • FLIP uses a one way mapping between the “private” address, used to register an endpoint of a network connection, and the “public” address used to advertise the endpoint.
  • FLIP routes messages based on NSAP.
  • FLIP uses a bit in the message header to request transmission of sensitive messages across trusted networks.
