Delay Bounds in a Network with Aggregate Schedulingopment. With the rapid increase in the demand for reliable end-to-end QoS solutions, it becomes increasingly important to understand the implications of aggregate scheduling on the resulting QoS capabilities. This paper studies the bounds on the worst case delay in a network implementing aggregate s

A Queue Management System for Differentiated-Services IP Routersn conjunction with scheduling mechanisms, is able to support class differentiation. The general principles and the architecture of the queue management system are presented. The proposal is supported by a prototype that was subject to several tests, in terms of packet drops and burst tolerance. The

Random Early Markingsource rate to observed marking.The marking probability is exponential in a link congestion measure, so that the end- to-end marking probability is exponential in a path congestion measure. Marking allows a source to estimate its path congestion measure and adjusts its rate in a way that aligns indi

In this study, we present a scheme for adapting the transmission rate of multimedia applications to the congestion

On ACK Filtering on a Slow Reverse Channele-ACK per connection at a time in the buffer at the input of a slow channel has been studied. In this paper we show that this is too aggressive for short transfers. We study first static filtering where a certain ACK queue length is allowed. We show analytically how this length needs to be chosen. W

Design, Implementation and Test of a RSVP Agent Based on a Generic QoS API1nt. However, QoS is difficult to implement in a best-effort network as Internet. For IP QoS, the Internet Engineering Task Force (IETF) developed two models: the Integrated Services architecture (IntServ) and the Differentiated Services (DiffServ). The IntServ architecture uses RSVP as a protocol fo

On the Feasibility of RSVP as General Signalling Interfacegreement exists, how such signalling has to be carried out. In this paper, we adopt the point of view that signalling of Quality of Service (QoS) requests must not be abandoned, given the high level of uncertainty about the future traffic mix in an integrated communication network. We present a flex

Field-Trial of Dynamic SLA in Diffserv-Capable Networked to meet such requirements. Currently, it is assumed that Diffserv is used under static Service Level Agreement (SLA). Under static SLA, the agreement between the service provider and the service subscribers are made as a result of negotiation between human agents. However, the service subscribers
