This working group is chartered to define a framework and techniques for Quality of Service (QoS) Routing in the Internet. QoS Routing allows the network to determine a path that supports the QoS needs of one or more flows in the network. The path chosen may not be the "traditional shortest path" that is typically computed based on current metrics and policies. The group's work will focus on how to select and maintain packet forwarding paths capable of meeting specific service class objectives. In particular, the techniques will specify what extensions and adaptations to routing and QoS setup protocols are required to support QoS routing and new packet handling techniques that may be needed to avoid packet loops for QoS flows. While it is not intended, this may also spawn the development of new routing protocols that can specifically address QoS routing. The WG will identify topics and issues in QOS routing which require additional research. The WG needs to work closely with other routing protocol working groups such as OSPF, IDR, BGP, and IDMR. A close relationship with the RSVP,IntServ, and ISSLL working groups is also needed to understand the QoS signalling and specification.
