A Generic Charging Policy Based Accounting for Web Services
Metering and charging are basic accounting functions that are essential for commercial usage of web services. Current charging and accounting schemes primarily involve users being charged flat or based on the connection/session time. Accounting management of web services should provide for metering, charging, accounting, billing, payment and auditing. The authors have extended their earlier work, a Policy based Accounting for Web Services (WS-PACT), to develop a generic and comprehensive charging policy that can cater to different charging patterns. WS-PACT provides a flexible model to meet the varying billing and payment needs of service providers.
