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...

This article discusses a novel approach for realizing traffic engineering in the framework of new-generation multilayer networks based on the GMPLS paradigm. In particular, the proposed traffic engineering system is able to dynamically react to traffic changes while at the same time fulfilling QoS requirements for different classes of service. The proposed solution consists of a hybrid routing ...

Keywords: Internet routing Traffic engineering Transit-edge routing LISP Game theory a b s t r a c t The relentless growth of Internet, which has resulted in the increase of routing table sizes, requires consideration and new direction to address Internet scalability and resiliency. A possible direction is to move away from the flat legacy Internet routing to hierarchical routing, and introduce...

Traffic measurement plays an important role in data centers. Many data center management tasks ranging from performance diagnosis, anomaly detection to traffic accounting and engineering all rely on accurate and on-time measurement of the traffic from different tenants and applications. For example, to perform traffic engineering, we need to correctly detect large flow aggregates and pick bette...

T urning left across opposing traffic at a signalized intersection could result in a traffic accident, as well as create motorist delay. A solution to the left-turn problem may be the addition of a left-turn phase when certain guidelines are met.’ After a decision has been made to add a left-turn phase, one of two basic alternative phasing methods is commonly used. In Kentucky, the predominant ...

This paper describes multi-layer traffic engineering and signaling technologies in photonic-GMPLS-router networks. Multi-layer traffic engineering, which yields the dynamic cooperation of IP and photonic layers for providing IP services cost-effectively, is described. To realize multi-layer traffic engineering, we propose an OSPF extension that advertises both the number of total wavelengths an...

The Internet is a collection of packet based, hop-by-hop routed networks. Internet traffic engineering is the process of allocating resources to meet the performance requirements of users and operators for their traffic. Current mechanisms for doing so, exemplified by TCP’s congestion control, or the variety of packet marking disciplines, concentrate on allocating resources on a per-packet basi...

Network operators control the flow of traffic in today’s IP networks by manipulating the configuration of the routing protocols running on their routers. Although intradomain traffic engineering is largely isolated to individual Autonomous Systems (ASes), changes to interdomain routing policies affect the traffic load in other domains. In this paper, we argue that neighboring ASes should cooper...

This document defines the purpose of the Hybrid Network Traffic Engineering Software (HNTES) system, lists its functional requirements, and describes its high-level architecture. This is a revised version of the HYbrid Network Engineering Software (HYNES) document, dated Dec. 30, 2010. The software has been renamed to better reflect its purpose as a traffic engineering solution.
