Multipath traffic engineering utilizes several multiple paths for transporting the traffic demand between source LSR and destination LSR. Using the multipath, we can effectively control the network resource utilization. If maximally disjoint multiple LSPs are found, the multipath traffic engineering can provide appropriate fault-tolerant routing. In this paper, we propose the fault-tolerant mul...

Current intra-domain Traffic Engineering (TE) relies on offline methods, which use long term average traffic demands. It cannot react to realtime traffic changes caused by BGP reroutes, diurnal traffic variations, attacks, or flash crowds. Further, current TE deals with network failures by pre-computing alternative routings for a limited set of failures. It may fail to prevent congestion when u...

Intra-domain Traffic Engineering (TE) aims to route around failures and congestion, and balance load in an ISP’s network. Current TE relies on offline methods which use long term average traffic demands. It cannot react to traffic changes caused by BGP reroutes, diurnal traffic variations, attacks, or flash crowds. Further, current TE deals with network failures by pre-computing alternate routi...

This one-day class introduces the importance of traffic analysis in the provisioning of optimum wireless networks. The course is divided into four general areas that cover terminology and background knowledge, traffic models for voice applications, traffic models for data applications, and engineering applications and techniques. The goal is to provide the trainee with sound engineering and sta...

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...
