Traffic engineering with traditional IP routing protocols

Traffic Engineering With Traditional IP Routing Protocols

Traffic engineering involves adapting the routing of traffic to the network conditions, with the joint goals of good user performance and efficient use of network resources. In this paper, we describe an approach to intradomain traffic engineering that works within the existing deployed base of Interior Gateway Protocols (IGPs), such as Open Shortest Path First (OSPF) and Intermediate System-In...

IP Traffic Engineering with Weighted Distributed Routing

In this paper an introduction to QoS traffic engineering is presented. Particular emphasis is given to the scalability issues arising from state information that has to be stored in routers. It is found that while an MPLS based solution could potentially provide a more optimal results to QoS TE, it is quite unscalable as well as inflexible in case of failure. An IP based solution should be pref...

A Flow-Based Approach for IP Traffic Engineering Utilizing Routing Protocols With Multiple Metric Types

Traffic Engineering and Routing in IP Networks with Centralized Control

There have been research initiatives in centralized control recently, which advocate that the control of an autonomous system (AS) should be performed in a centralized fashion. In this paper, we propose an approach to perform traffic engineering and routing in networks with centralized control, named LP-redirect. LP-redirect is based on an efficient formulation of linear programming (LP) that r...

Energy-aware IP traffic engineering with shortest path routing

Internet energy consumption is rapidly becoming an issue due to the exponential traffic growth and the rapid expansion of communication infrastructures worldwide. We address the problem of energy-aware intra-domain traffic engineering in networks operated with a shortest path routing protocol. We consider the problem of switching off (putting in sleep mode) network elements (links and routers) ...
