چکیده

Next generation multi-service networks must meet basically two fundamental requirements: Quality of Service (QoS) in an Internet-based context and Traffic Engineering (TE) functionalities. DiffServ-over-MPLS stands for the most reliable solution to fulfill them in a flexible way. Anyway, even if both Diffserv and MPLS technologies have been the subjects of several works, the design and the implementation of the integrated DiffServ-over-MPLS solution, still presents unsolved nuts. This paper attempts to highlight the open issues of the integrated solution, giving an overview of the involved technologies and the possible solutions that can be implemented in such a scenario. Then a simulation tool designed to investigate such open issues is proposed. The aim is to realize a tool able to simulate different DiffServ-over-MPLS solutions so as to provide some guidelines for the analysis and the design of different network scenarios.

Effect of Packet Delay Variation on Video-Voice over DiffServ-MPLS in IPv4-IPv6 Networks

Over the last years, we have witnessed a rapid deployment of real-time applications on the Internet as well as many research works about Quality of Service (QoS), in particular IPv4 (Internet Protocol version 4). The inevitable exhaustion of the remaining IPv4 address pool has become progressively evident. As the evolution of Internet Protocol (IP) continues, the deployment of IPv6 QoS is under...

Traffic Engineering and Network Management System for QoS-Guaranteed DiffServ Provisioning

This paper proposes an integrated traffic engineering and management system for DiffServ-over-MPLS services in Next Generation Internet (NGI). Using the proposed traffic engineering functions for DiffServover-MPLS network, the Internet service provider (ISP) can easily configure Diffserv-over-MPLS traffic flows among customer’s distributed sites, and can provide guaranteed end-to-end QoS by con...

Design and Implementation of Performance Management for the DiffServ-aware-MPLS Network

MPLS has been developed to provide efficient traffic engineering capability for the massive high-speed Internet traffic. The major advantages of the MPLS are (i) fast label switching mechanism to increase the packet forwarding capability, and (ii) the connection oriented traffic engineering to provide flexible load balancing in the transit network. DiffServ-over-MPLS architecture provides diffe...

Discrete Event Simulation of the DiffServ-over-MPLS with NIST GMPLS Lightwave Agile Switching Simulator (GLASS)

In this paper, we explain the discrete event network simulation for DiffServ-aware-MPLS on the GMPLS-based WDM Optical Network. The simulation has been performed on the NIST GMPLS Lightpath Agile Switching Simulator (GLASS). We also briefly explain the design and implementation of the GLASS, and report the current implementation status and experimental results. The NIST GLASS has been developed...

Management of DiffServ-over-MPLS Transit Networks with BFD/OAM in ForCES Architecture

This paper proposes a management of DiffServ-over-MPLS transit network with BFD(Bidirectional Forwarding Detection)/OAM (operation, administration and maintenance) in ForCES (Forwarding and Control Element Separation) architecture for QoS-guaranteed DiffServ-over-MPLS traffic engineering. The proposed BFD and ForCES functions are implemented on Intel 2400 network processor, where BFD/OAM packet...
