Why Not RSVP over DTM ?

Abstract

This paper suggests the use of the DTM technology as a solution to the transmission of applications with strict need of bandwidth, instead of the use of the traditional ATM technology. The DTM is a broadband network architecture based on synchronous fast circuit switching solution with a constant delay, perfect to the telephony network which is optimized for the characteristics of voice communication, that is, fixed-sized channels and provision of QoS real-time guarantees. Furthermore, the users require access to new services like audio, video and data which is discussed in this paper by proposing the IETF IntServ and the DTM integration supporting dynamic allocation of resources in a circuit switching network. An overview of the integration of the IntServ guaranteed service/RSVP protocol with the DTM technology on the signalling, reservation and management of the allocated bandwidth before the DTM channel establishment is presented.
