NGN is bringing voice, video, data and other tripleplay services to a single platform. Policy Based Network Management (PBNM) is becoming indispensable and complicated while converging those services with assured Quality of Service (QoS). Recent work in this area has focused on PBNM considering a particular information domain: e.g. Service Level Agreement (SLA) and/or QoS Routing etc. In this paper we present an architecture with PBNM focussing on access network optimization while taking SLAs, business objectives, routing rules, service Info, user profiles and platform conditions into account. Call setup is based on Session Initiation Protocol (SIP), a text based application layer signaling protocol adopted in NGN for controlling multimedia communications. The service, control and network planes in the proposed architecture are kept isolated. Connection Admission Control (CAC) is correlated with proposed PBNM framework. We also propose to distribute the policy sensitive CAC function between the Call Server (CS) and Session Border Controller (SBC). Two policy enforcement and dissemination modes (Provisioning and outsourcing) are elaborated.
