Abstract

Traffic engineering encompasses a set of techniques that can be used to control the flow of traffic in data networks. We discuss several of those techniques that have been developed during the last few years. Some techniques are focused on pure IP networks while others have been designed [...]

Abstract

Constraint-based routing (CR-LDP) extends the features of MPLS Label Distribution Protocol (LDP) working in conjunction with a wide variety of QoS scenarios and services including IP differentiated services, integrated services, traffic engineering, Asynchronous Transfer Mode (ATM) [...]

Abstract

This paper describes two traffic engineering techniques for implementing proportional differentiated services based on Multiprotocol Label Switching constraint based routing. Both use a dynamic bandwidth allocation scheme to modify the bandwidth reserved by each traffic class according [...]

Abstract

The provision of services and the production of wares and services nowadays often require the cooperation of partners from different sectors. These cooperations can comprise public and private organizations, companies, universities, NGOs, and other groupings as well as individuals. [...]

Abstract

Quality of Service (QoS) is a basic functionality that the Internet needs to be able to cope with when the applications increased in number and varied in use. Internet QoS issues concerning the Internet involves many different areas: end user QoS, ISP network QoS, backbone QoS. Backbone [...]

Abstract

The evolution of Internet and its successful technologies has brought a tremendous growth in business, education, research etc. over the last four decades. With the dramatic advances in multimedia technologies and the increasing popularity of real-time applications, recently Quality [...]

Abstract

O surgimento de novas aplicações na Internet, tais como voz sobre IP (VoIP), ensino a distância interativo, realidade virtual, videoconferência, etc, impõe a necessidade de garantias de qualidade de serviço (QoS - Quality of Service) fim-a-fim. Tais aplicações exigem limites [...]

Abstract

Tato práce se zabývá technologií Multiprotocol Label Switching a to zejména moderními metodami, které je možné použít v rámci této technolologie. Jako příklad lze uvést využití podpory kvality služeb při směrování. V práci jsou navrhnuty a simulovány různé [...]
