C. Jacquenet This draft specifies a set of Policy Rule Classes (PRC) for the enforcement of an IP traffic engineering policy by COPS-PR ([2])- capable routers. Instances of such classes reside in a virtual information store, which is called the IP Traffic Engineering Policy Information Base (IP TE PIB). The corresponding IP TE policy provisioning data are intended for use by the COPS-PR IP TE Client- Type([3]), and they will complement the PRC classes that have been defined in the Framework PIB ([4]).
