This paper proposes a new method of bandwidth allocation during congestion, called the proportional allocation of bandwidth. Traditionally, max-min fairness has been proposed to allocate bandwidth under congestion. Our allocation scheme considers the situation where flows might have different subscribed information rates, based on their origin. In proportional allocation of bandwidth, during co...

This document was originally submitted as an internet draft in November of 1997. As one of the documents predating the formation of the IETF’s Differentiated Services Working Group, many of the ideas presented here, in concert with Dave Clark’s subsequent presentation to the December 1997 meeting of the IETF Integrated Services Working Group, were key to the work which led to RFCs 2474 and 2475...

This document contains a tutorial on the recent work in the area of offering services in the Internet. We cover the principles and some of the details of Integrated Services and Differentiated Services. We also explain the relationship to RSVP of each of these architectures. Finally, we draw some conclusions about the relationship of these architectures to SURFnet.

Overlay multicasting technology is now considered as a promising alternative to the native IP multicasting. While many studies are currently focused on how to build an overlay tree/mesh on top of conventional networks in a self-organized fashion, only limited attention has been directed toward QoS provisioning. QoS can be provisioned by leveraging the implementation of differentiated services i...

It is now quite agreed that the IP layer should provide more sophisticated services than the simple best-effort service to meet the application’s quality of service requirements. Different proposals for improving the IP stack have been proposed but their deployment on experimental network shows different scaling problems. In this paper we present a new differentiated service scheme called “Equi...

The integration of renewable sources poses challenges at the operational and economic levels of the power grid. In terms of keeping the balance between supply and demand, the usual scheme of supply following load may not be appropriate for large penetration levels of uncertain and intermittent renewable supply. In this paper, we focus on an alternative scheme in which the load follows the suppl...

In paper we present an overview of recent work on resource pricing for differentiated services in the Internet. This approach is based upon encouraging cooperation between the end-systems and the network by use of the correct feedback signals. These signals reflect the congestion shadow prices at a resource, and their use means then even ‘selfish’ end-systems, acting in their own best interests...

Architectures for Internet quality of service (QoS) have been under discussion for over a decade and, with the commercialization of the Internet, the topic has become increasingly important. This paper gives a brief background and history of QoS for the Internet, then introduces and motivates the Differentiated Services (Diffserv) approach. The major advantages of the Diffserv approach are that...

In order to support emerging network businesses, such as Voice-over-IP (VoIP), virtual learning, video conferencing, and telemedicine, the Internet has to provide classes of service that are better than traditional ‘best-effort’ service. In computer networks, Quality of Service (QoS) is defined as the mechanisms that allow differentiation of network services based on their unique service requir...
