Application-layer framing

Application-layer framing or application-level framing (ALF) is a method of allowing an application to use its semantics for the design of its network protocols.

This procedure was first proposed by D. D. Clark and D. L. Tennenhouse.[1] It works as follows:

This procedure simplifies the quality of service negotiation and provides a simpler method of error checking.

The real-time protocol (RTP) is an example of where the semantics of the real-time application are used to segment the data.
