           Coordinated Address Space Management architecture
            draft-li-opsawg-address-pool-management-arch-01

Abstract

   IP addresses work as a basic element for providing broadband network
   services.  However, the increase in number, diversity and complexity
   of modern network devices and services creates unprecedented
   challenges for the currently prevailing approach of manual IP address
   management.  Manually maintaining IP addresses could always be sub-
   optimal for IP resource utilization.  Besides, it requires heavy
   human effort from network operators.  To achieve high utilization and
   flexible scheduling of IP network addresses, it is necessary to
   automate the address scheduling process.  This document describes an
   architecture for the IP address space management.  It includes
   architectural concepts and components used in the CASM (Coordinated
   Address Space Management), with a focus on those interfaces to be
   standardized in the IETF.
