    摘要: A method, apparatus and computer program product for managing content sessions within a network is presented. The systems disclosed herein are able to detect a requirement to modify bandwidth usage within the network either proactively or reactively. In response, example embodiments apply an adaptive bit rate adjustment technique to the content sessions to adjust a data rate associated with each content session according to the requirement to modify bandwidth usage within the network. Example embodiments also then apply a quality of service adjustment technique to the content sessions to adjust a bandwidth allocation assigned between a client and server based upon the adaptive bandwidth adjustment technique. Application of the adaptive bit rate and quality of service adjustment techniques may be policy based. Example embodiments also may monitor a plurality of servers supporting content sessions, detect a failure at a first server and move content sessions to a second server.

    摘要: Techniques disclosed herein include systems and methods that provide a workflow-based session manager or workflow engine for a content delivery system, such as for delivering video-on-demand, streaming audio, streaming video, etc. Such techniques increase velocity and flexibility of deploying new features and services in a video delivery system. Techniques include a session management model provides a service-oriented and workflow-based approach. As a service-oriented approach, each functional session management step can be represented as a business service. As a workflow-based solution, a sequence of steps to be performed can be defined as data, rather than being hard-coded inside an application. Defined as data, steps (nodes, tasks) can then be created and changed using a graphical editor. New services can be added by defining actions for the new service, and adding a node to a given session management workflow sequence. Techniques include a workflow engine that initiates session management in realtime.
