NET based OSS architecture/performance comparison with EAI/WF engines

As network technologies have evolved tremendously and the customer demand for telecommunications services has increased so fast, the need for OSS to process various service orders and manage a lot of equipment has become bigger and bigger. To meet these requirements, an OSS must have some special characteristics, such as fast time-to-market deployment, extensible architecture, simple user interface, etc. Most OSS processes are a well set-up series of tasks or actions with the order in which they must be performed, so we can use a commercial workflow engine to achieve time-to-market OSS deployment. We describe and compare the architecture and framework of two .NET EAI/Workflow solution based OSS and test the performance. The Microsoft BizTalk server and the next version, Jupiter, are EAI/Workflow engines that can be used to enforce the OSS workflow definitions.
