Working on Siemens Session Manager product.
Siemens Session Manager is an AAA or Authentication, Authorization, and Accounting product. It refers to a security architecture for distributed systems for controlling which users are allowed access to which services and tracking which resources they have used. Two network protocols providing this functionality are particularly popular: the RADIUS and Diameter protocol.
Working on Siemens Policy Manager product.
Siemens Policy Manager is a Policy and Charging Rules Function (PCRF) product. PCRF is the software node designated in real-time to determine policy rules in a multimedia network. As a policy tool, the PCRF plays a central role in next-generation networks.
My task on both products was a requirement analysis, design, implementation and testing (component, integration, and end-to-end testing).
