Abstract: The conceptual Web Service Architectural Model for the VoD System that consists of policies, resources, services and messages is presented by including the life cycle for video service interaction and the relationship between the key modules of the video service. A performance enhancement for the innovative SOAP Communication Model with modified message exchange pattern is proposed where a MulticastMessageContext with MulticastMessageReceiver is introduced in the SOAP Communication Model to support unicast as well as multicast of video data as per the client requirements. This model makes the existing “one request-one response” message exchange pattern as “one request-many responses” message exchange pattern and inherently reduces the bandwidth requirements. In the implemented VoD Systems, the policies are handled by authentication service provider. The services are handled by either MessageContext or MulticastMessageContext. The resources are handled using download and play approach. The messages are handled using SOAP communication with modified message exchange patterns.
