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...

The increasing diversity of Internet appliances calls for an architecture f o r performance differentiation on inforniatiori access. The World Wide Web is the dominant interface f o r inforniation access toduy. Web proxy caching is the key performance accelerator in the web infrastructure. While many research efforts addressed pegorniance differentiation in the network and on web servers, provi...

Remote Monitoring MIB Extensions for Differentiated Services Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this...

Internet is moving towards the time of Quality of Service (QoS) networking. This move is taking place through the application of Differentiated Services (DiffServ) architecture. DiffServ offers low overhead tools to implement class based differentiation for the traffic. Decision of differentiation is, however, left as an open matter, to be settled between service provider and customer. Majority...

To support Quality-of-Service (QoS) provisioning in highly dynamic mobile environments, we propose a signaling protocol allowing mobile users to contact a Differentiated Services bandwidth broker for QoS negotiation. The protocol can also be used for QoS negotiations between bandwidth brokers.

The paper describes the concept and the implementation of Differentiated Services over ATM. ATM components are being used in order to implement DiffServ traffic conditioning components such as shaping and policing. The implementation architecture based on a Linux router platform and some initial performance measurement results are presented.

UMTS networks will be based on the Internet Protocol (IP) to provide an efficient support for applications with bursty traffic characteristics, e.g., WWW browsers. Such IP-based networks must include Quality of Service (QoS) mechanisms to enable the usage of real-time applications, such as mobile telephony. Different network services are necessary to satisfy the different needs of applications ...
