In this paper, we attempt to understand the benefits of MPLS traffic engineering through a case study. Specifically, we do a comparative study of MPLS traffic engineering in the presence of dynamic constraint-based routing compared to destination-based routing. For this case study, we use a model derived from an actual service provider network. Different control schemes that can be deployable f...

This paper discusses Traffic Engineering with Multi-Protocol Label Switching (MPLS) in an Internet Service Provider’s (ISP) network. In this paper, we first briefly review MPLS, Constraint-based Routing and enhanced link state Interior Gateway Protocols (IGPs) to provide a background for Traffic Engineering. We then discuss the general issues of designing an MPLS system for Traffic Engineering....

With the rising popularity of the Internet there have arisen corresponding requirements for network reliability, efficiency, and service quality. Internet service providers are responding to these developments by critically examining every aspect of their operational environment, looking for opportunities to scale their networks and optimize performance. In this context, traffic engineering has...

In modern backbone networks with heterogeneous traffic, providing connectivity is taken for granted. The MPLS technology is a de-facto standard in modern backbone networks because of the applications it enables, in particular L2/L3 VPNs and traffic engineering. This paper deals with traffic engineering in MPLS backbone networks. We propose a method of gathering network performance parameters an...

car-following models are among the most important components of micro traffic flow simulation which is studiedby transportation experts to evaluate new applications of intelligent transportation systems. until now, several carfollowingmodels have been proposed. an obvious disadvantage of the former models is the great number of parameterswhich are difficult to calibrate. in this paper, a car-fo...

The TEFID framework for Traffic Engineering in Future Internet Domains is outlined. The framework provides QoS and GoS by a set of inter-dependent traffic control and resource allocation functions. Traffic engineering relies on a relationship between three models: traffic model, network model, and performance model. The objective is to achieve fair and efficient sharing of resources among the n...

We present an application of multiple-objectives evolutionary optimization to the problem of engineering the distribution of the interdomain traffic in the Internet. We show that this practical problem requires such a heuristic due to the potential conflicting nature of the traffic engineering objectives. Furthermore, having to work on the parameter’s space of the real problem makes such techni...

Traffic engineering broadly relates to optimization of the operational performance of a network. This survey discusses techniques like multi-path routing using traffic splitting, constraint-based routing, pathprotection etc. that are used for traffic engineering. Multipath routing can be effectively used for maximum utilization of network reso urces. It gives the node a choice of next hops for ...
