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...

Our aim in this paper is to apply the technique of parametric ‘bootstrapping’ (or ‘resampling’) to determine what sampling frequency of traffic measurements is necessary for the proper engineering of high-speed data networks. Recent studies have shown that Fractional Brownian Motion (FBM) is a good model for the traffic observed in high-speed data networks, capturing both self-similarity and lo...

Traffic Engineering (TE) is an important aspect of contemporary network management. Offline traffic engineering approaches aim to optimize network resources in a static manner, but require accurate estimation of traffic matrices in order to produce optimized network configurations for long-term operation. In order to avoid network congestion and subsequent service disruptions, handling traffic ...
