         draft-boucadair-connectivity-provisioning-protocol-22

Abstract

   This document defines the Connectivity Provisioning Negotiation
   Protocol (CPNP) which is designed to facilitate the dynamic

   CPNP is a generic protocol that can be used for various negotiation
   purposes that include (but are not necessarily limited to)
   connectivity provisioning services, storage facilities, Content
   Delivery Networks, etc.
