Title : Transaction UDP plus Timers (TUDP) for MEGACO Author(s) : F. Cuervo, A. Rayhan, J. S. Mayer Filename : draft-cuervo-megaco-tudp-00.txt Pages : 22 Date : 15-Jun-99

This document describes transaction-oriented reliable UDP with timers (TUDP). It can be used to provide reliable delivery of transactions for MEGACO [1] applications. The objective of the protocol is to deliver transactions and messages within the time constraints of the application, i.e., the application timer. Transaction sequences are ordered perstream, and superseding of transactions is allowed.

MEGACO implementations may choose to use TUDP for applications that require high fan-out, reliable and ordered delivery. Other transports such as TCP, UDP or SIGTRAN may be useful in other situations.
