Real-Time Services (RTS) will rely on distributed capabilities to enable end-to-end management of IP based voice and video services across multiple domains. Policy Based Enterprise Management (PBEM) will be a key RTS enabler by coordinating and automating management processes among domains. This will facilitate effective distributed management of RTS services across the enterprise. For example, PBEM will execute Commanderpsilas Intent (CI) by translating it into sets of event triggered conditions and actions that adjust bandwidth, traffic priority and traffic admission controls. This paper discusses how PBEM enables agile network operations by providing real-time management responses to high impact events. It will also address the relevance of Policy Based Management (PBM) in RTS and the end-to-end management capability to be supported by PBEM in support of the RTS Pilot. Pilot scenarios are proposed that include: focused overload, Commanderpsilas Intent (CI) and RTS bandwidth reallocation, failure mitigation, and synchronizing policies across multiple management domains. A framework for a PBEM test-bed that will mature the capabilities for a RTS pilot targeted for FY09-FY11 time frame is provided. Based on the scenarios described in this paper, operational metrics are identified that will allow the benefits of PBEM to be evaluated in a RTS test-bed activity and during the RTS pilot.
