Quality of service based routing: A performance perspective
- …Recent studies provide evidence that Quality of Service (QoS) routing can provide increased network utilization compared to routing that is not sensitive to QoS requirements of tra c. However, there are still strong concerns about the increased cost of QoS routing, both in terms of more complex and …

Efficient Support for Interactive Scanning Operations in MPEG-Based Video-On-Demand Systems
- …In this paper, we present an efficient approach for supporting fast-scanning (FS) operations in MPEG-based video-on-demand (VOD) systems. This approach is based on storing multiple, differently encoded versions of the same movie at the server. A normal version is used for normal playback, while seve…

Roadrunner
- …Introduction On-demand multimedia applications can impose Quality-of-Service (QoS) parameters on streaming data transfers performed by operating systems. For multimedia servers, high performance in the form of low latency and high throughput are also necessary. This work seeks to improve the perfor…

On the Effectiveness of Path Pre-Computation in Reducing the Processing Cost of On-Demand QoS Path Computation
- …Quality of Service (QoS) routing algorithms have become the focus of recent research due to their potential for increasing the utilization of an Integrated Services Packet Network (ISPN) that handles requests with QoS requirements. While heuristics for determining paths for such requests have been f…

Design and Implementation of QoS Routing Extensions to Gated OSPF with Interface to RSVP
- …This document describes the design and some details of a reference implementation of the QoS routing extensions to the OSPF routing protocol [10] proposed in [1]. This reference implementation is based on the version 4 of the Gated Daemon (gated) [5] uni-cast distribution. It has undergone limited t…
