Abstract: Embodiments of the invention provide systems and methods for providing high availability in a session supporting multiple protocols. More specifically, embodiments of the present invention provide for high availability processing by decoupling an application session from protocol processing. That is, protocol processing can be performed at protocol nodes specific to each protocol session. The protocol nodes can then pass messages to and from a session node that performs session processing other than the protocol processing. The session of the first session node can be replicated on a second session node and, upon a failure of the first session node, control of the session can be passed to the second session node. The session can then be continued on the second session node according to a number of different models described herein.

Abstract: Embodiments of the invention provide systems and methods for providing services such as provided by Internet Protocol (IP) Multimedia Subsystem (IMS) with an IP network that is not the IMS. According to one embodiment, a system for providing communication services can comprise a communication network, one or more subsystems communicatively coupled with the network and adapted to provide one or more telco functions, and one or more applications communicatively coupled with the network and adapted to utilize the telco functions.

Abstract: A framework for improving program performance by locality-enhancing transformations is presented. This framework is appropriate for modern high-performance machines that have a memory hierarchy. The invention orchestrates the flow of data through the memory hierarchy directly, and is thus able to overcome limitations of existing approaches. This new approach allows for efficient execution of imperfectly nested loop programs which are ubiquitous in numerical calculations and database operations, and it can be integrated into high-performance optimizing compilers.
