Description of Working Group:

Note: Rob Coltun (rcoltun@siara.com) is technical advisor

The Internet Traffic Engineering working group is chartered to define, develop, specify, and recommend principles, techniques, and mechanisms for traffic engineering in the Internet. The working group will also serve as a general forum for discussing possible improvements to IETF protocols to advance the Traffic Engineering function.

Internet Traffic Engineering is defined as that aspect of Internet network engineering which is concerned with the performance optimization of operational networks. It encompasses the application of technology and scientific principles to the measurement, modeling, characterization, and control of Internet traffic, and the application of such knowledge and techniques to achieve specific performance objectives, including the reliable and expeditious movement of traffic through the network, the efficient utilization of network resources, and the planning of network capacity.

The primary focus of the TE WG concerns the control aspects of intra-domain Internet traffic engineering. This includes control aspects pertaining to intra-domain routing and control aspects pertaining to intra-domain network resource allocation. Techniques already in use or in advanced development for Internet TE include ATM and Frame Relay overlay models, MPLS based approaches, constraint-based routing, and TE methodologies in Diffserv environments. The WG will describe and characterize these and other techniques, document how they fit together, and identify scenarios in which they are useful.

The working group may also consider solutions to the problem of traffic engineering across autonomous systems boundaries.

As part of its deliverables, the TE WG will produce a comprehensive framework document that articulates the general principles and requirements for Internet traffic engineering, with emphasis on techniques in use or in advanced development. The working group may also produce documents that suggest possible improvements to IETF protocols to support the traffic engineering function. Additionally, the WG may produce specialized requirements documents that focus on specific aspects of Internet traffic engineering. Other informational documents may be produced as necessary.

The TE WG will interact with other areas of IETF activity whose scope intersect with the definition of traffic engineering. These include various working groups in the Routing Area (e.g. MPLS, IS-IS, OSPF, etc), the Transport Area (e.g. Diffserv, IPPM, RAP, RTFM,), and the Operations and Management Area (e.g. POLICY, RMONMIB, DISMAN, etc).
