         Connectivity Provisioning Negotiation Protocol (CPNP)
         draft-boucadair-connectivity-provisioning-protocol-14

Abstract

   This document specifies the Connectivity Provisioning Negotiation
   Protocol (CPNP) which is used for dynamic negotiation of service
   parameters.

   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 footprint, etc.  The protocol can be extended with
   new Information Elements.
