    MSRP syntax is similar to other IETF text based protocols such as SIP, HTTP and RTSP. MSRP requires a reliable transport layer, like TCP.Each message is either a request or a response and uses URIs; a message contains headers and a body that can carry any type of data, including binary information.

    In computer networking, cell relay refers to a method of statistically multiplexing small fixed-length packets, called "cells", to transport data between computers or kinds of network equipment. It is a reliable , connection-oriented packet switched data communications protocol .

  7. Frame Relay - Wikipedia

    en.wikipedia.org/wiki/Frame_Relay

    The Frame Relay network handles the transmission over a frequently changing path transparent to all end-user extensively used WAN protocols. It is less expensive than leased lines and that is one reason for its popularity. The extreme simplicity of configuring user equipment in a Frame Relay network offers another reason for Frame Relay's ...

    ITU used SDLC as a basis to develop LAPF for the Frame Relay environment, along with other equivalents: LAPB for the X.25 protocol stack, LAPM for the V.42 protocol, and LAPD for the ISDN protocol stack. In Frame Relay Local Management Interface (LMI) messages are carried in a variant of LAPF frames. LAPF corresponds to the OSI model Data Link ...
