This paper describes the proposed Differentiated Services schemes, makes comparison between proposals, and matches them against the proposed Differentiated Services (DS) byte and the DS architecture proposed by the Differentiated Services Working Group (DSWG). In addition an application feedback is introduced as a new DS service. This method enables applications to prioritize packets within an ...

The paper discusses several approaches to use the Differentiated Services Architecture for providing better services to the users of the World Wide Web. In the future Internet a user wants to have the possibility to select between different service levels to get specific web-contents. The sender orientation of the Differentiated Services Architecture imposes some difficulties in providing the u...

The Differentiated services architecture (diffserv) proposed by the Internet Engineering Task Force (IETF) [1] provides service differentiation in the Internet in an efficient and scalable manner. The central idea of diffserv is that the Type Of Service field (TOS) in the IPv4 header can be used to prioritize traffic in an aggregated manner. In this paper we work on the resource management impl...

The Differentiated Services (DiffServ) approach will also bring benefits for multicast applications which need quality of service support. For instance, a highly reliable multicast service can be provided based on the proposed Expedited Forwarding behavior [8]. Such a service may also be used advantageously in a global computing cluster infrastructure, e.g., for distribution of synchronization ...

Even though broadband high speed Internet service has been always attractive choice to Internet users, its deployment has not been very successful. Until very recently most broadband access providers offer a single quality level and price. We propose a definition of Quality of Service (QoS) in a broadband network, present a measurement of the proposed QoS, and discuss its implementability. Furt...

This draft presents a Feedback Control extension to Differentiated Services. Differentiated Services have been designed for scalability through handling aggregates of traffic instead of individual flows as in the Integrated Services. However, it has been observed that the DS mechanism in some situations can hardly achieve the desired quality of service and may result in unfair conditions. To re...

This paper describes a hierarchical architecture of active policies [1] that performs the management of a differentiated services (DiffServ) network. These policies monitor quality of service (QoS) parameters and dynamically optimize some aspects of the existing equipment and services to provide the best possible QoS to users. This helps the enforcement of Service Level Agreements (SLA) between...

This work presents and evaluates a functional architecture and a framework for mapping service management policies and constraints into differentiated services (DiffServ) mechanisms. Several simulation scenarios described through the use of service policies are introduced and analyzed. It is shown that the use of service level management allows for efficient dynamic traffic engineering of DiffS...

This paper explains how DiffServ has been implemented in an IP network simulator using an asynchronous conservative parallel discrete event simulation (PDES) kernel. DiffServ provides Quality of Service (QoS) functionality for IP networks and is designed to provide greater scalability and lower overhead than previous IP based QoS schemes. The paper explains the DiffServ components that have bee...
