Towards Mobile Data Streaming in Service Oriented Architecture
Norman Ahmed, Mark H. Linderman, Jason R. Bryant · 2010
Service Oriented Architecture (SOA) is an architectural pattern providing agility to align technical solutions to modular business services that are decoupled from service consumers. Service capabilities such as interface options, quality of service (QoS), throughput, security and other constraints are described in the Service Level Agreement (SLA) that would typically be published in the service registry (UDDI) for use by consumers and/or mediation mechanisms. For mobile data streaming applications, problems arise when a service provider's SLA attributes cannot be mapped one-to-one to the service consumers (i.e. 150MB/sec video stream service provider to 5MB/sec data consumer). In this paper we present a generic framework prototype for managing and disseminating streaming data within a SOA environment as an alternative to custom service implementations based upon specific consumers or data types. Based on this framework, we implemented a set of services: Stream Discovery Service, Stream Multiplexor/Demultiplexor (routing) Service, Stream Brokering Service, Stream Repository Service and Stream Filtering Service to demonstrate the flexibility of such a streaming data framework within SOA environment.
