Abstract
This memo describes extensions to the OSPF [Moy98] protocol to
support QoS routes. The focus of this document is on the algorithms
used to compute QoS routes and on the necessary modifications to OSPF
to support this function, e.g., the information needed, its format,
how it is distributed, and how it is used by the QoS path selection
process. Aspects related to how QoS routes are established and
managed are also briefly discussed. The goal of this document is to
identify a framework and possible approaches to allow deployment of
QoS routing capabilities with the minimum possible impact to the
existing routing infrastructure.
In addition, experience from an implementation of the proposed
extensions in the GateD environment [Con], along with performance
measurements is presented.
