QoS[QOS]-capable communication network devices are now available, such as IP routers and switches, thus enabling the implementation of QoS-guaranteed services. Policy-Based Network Management (PBNM) is a framework to control these network devices with management rules that are called "Policy". At present, most network engineers on PBNM cope with only intradomain QoS-guaranteed services, but an enhanced framework for interdomain QoS-guaranteed services is required for real commercial networks that communicate with networks managed with a different policy. On real commercial networks, service providers have to charge customers for the interdomain QoS-guaranteed services. We focus on interdomain QoS provisioning and accounting. First, we discuss the policy framework and its architecture. Based on this framework and architecture, we propose two protocols: a Policy Advertisement Protocol (PAP) that distributes local policies among domains, and a Policy Negotiation and Notification Protocol (PNP) that sets up a QoS-guaranteed communication path among domains[INTD]. Our experimental network confirms that this interdomain QoS provisioning is effective when service
