In this paper we discuss the need for resource reservation in the Internet and examine some of the strengths and weaknesses of RSVP, which is currently the most popular of Internet reservation protocols that have been developed. We also discuss some alternative reservation protocols for packet networks, in particular the ATM Block Transfer(ABT) reservation(More)
User demand for more bandwidth and QoS support has fuelled interest in the use of ATM as an underlying link-layer technology in the Internet. The challenge is how best to exploit the potential benefits of ATM while maintaining the inherent strengths of the IP layer that have made the Internet so successful. The suitability of various schemes with regard to(More)
In this paper we present a new technique called Optimised Batch Patching with Classes of Service(OBP with CoS) which can be used to leverage the benefits of multicast within the context of 'near' video-on-demand systems in IP networks. OBP with CoS builds on an earlier scheme, known as Optimised Patching, but is different in two respects. Firstly, in OBP(More)

The growing use of multimedia communication applications with specific bandwidth and real-time delivery requirements has created the need for an Integrated Services Internet in which traditional best-effort datagram delivery can coexist with additional enhanced Quality Of Service(QOS) delivery classes. Such classes provide data flows with QOS commitments(More)
