Abstract
Diffserv (RFC 2474, 2475, and 3086) made explicit that IP QoS can be separated into the differentiated treatment given to packets in the forwarding path and the task of configuring these forwarding path components to allocate QoS according to policy and availability. The IETF Diffserv WG described the forwarding path architecture in detail and specified some specific forwarding path elements. This draft attempts a similar approach of specifying the elements of a diffserv control plane, gives a general architecture and example solution that fits into this architecture, and lays out some issues. An example of a diffserv control plane architecture is presented, derived from the control plane described in RFC2638, and an example implementation of that approach is briefly described. The authors hope to stimulate a discussion of the architectural model and its elements and to elicit more example solutions that may fit, change, or extend the model. A control plane must be configurable, secure, and monitorable. The authors believe the operations and management issues of a diffserv control plane must be made explicit and the approach to solving them properly constrained. Resolving operational and management issues is key to moving to availability of IP QoS. A pdf version of this document is available at: www.pollere.com at Resources: Current Work.
