The evolution of data communication technology has increased Internet traffic with negative effects on the user’s response time. An existing mechanism to combat such effect is Web caching, in which intermediary systems are used to temporarily store information that may be retrieved by multiple users or by a same user multiple times. Software engineers, designing applications for this new enviro...

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.

This document specifies Multiprotocol Label Switching (MPLS) Traffic Engineering Soft Preemption, a suite of protocol modifications extending the concept of preemption with the goal of reducing or eliminating traffic disruption of preempted Traffic Engineering Label Switched Paths (TE LSPs). Initially, MPLS RSVP-TE was defined with support for only immediate TE LSP displacement upon preemption....

We argue that today’s ad hoc inter-domain traffic engineering techniques be replaced with an architecture that is based on explicit coordination between ISPs. With explicit coordination, ISPs exchange information about their traffic and routing options, and all ISPs impacted by a potential routing change negotiate the actual change. This increases efficiency because it allows ISPs to find “win-...

Preamble In a few years, the Internet has rapidly evolved from a research network serving a handful of users to a huge interconnection of about 350 million hosts (June 2005 [ISC05]). In this way, the Internet is the largest distributed system ever built. The Internet is organized in a multitude of administratively independent networks called domains or Autonomous Systems (AS). For example, an A...

This paper presents an outlook on the perspectives of applying fuzzy logic techniques in traffic and transportation systems analysis and control. To this end, the theoretical and methodological principles of the fuzzy logic approach are outlined. An overview is given of the fuzzy logic applications in the transportation and traffic-engineering field, especially in the areas of estimation and pr...

Destination-based forwarding in traditional IP routers has not been able to take full advantage of multiple paths that frequently exist in Internet Service Provider Networks. As a result, the networks may not operate efficiently, especially when the traffic patterns are dynamic. This paper describes a multipath adaptive traffic engineering mechanism, called MATE, which is targeted for switched ...
