Intended status: Informational D. Dolson
Expires: December 30, 2018 June 28, 2018 CAPPORT Architecture draft-ietf-capport-architecture-02 Abstract This document aims to document consensus on the CAPPORT architecture. DHCP or Router Advertisements, an optional signaling protocol, and an HTTP API are used to provide the solution. The role of Provisioning Domains (PvDs) is described.
