New Access System Architecture (FASA)-Enabling Provision of Services Flexibly and Promptly

摘要

Flexible Access System Architecture (FASA) is a new access system architecture that satisfies various requirements from service providers and end users and enables prompt provision of services. NTT Access Network Service Systems Laboratories materialized this architecture, created a list of functions to be modularized, and investigated common API (application programming interface) specifications using use cases and dynamic bandwidth assignment as an example. A white paper was created as a reference. This article introduces some of the main elements of the white paper.
