Network requirements for open access networks

Abstract

Requirements for open access networks (OAN) for emerging services are described. The emergence of new services will necessarily lead to diverse technology requirements; and OAN will provide the basis for an infrastructure that is flexible, modular and evolvable. Existing standards are discussed in the context of how they respond to future needs. The author contends that these standards do not meet the requirements of emerging hybrid networks. Requirements, other than standards, for OAN are discussed.
