Abstract: A communication orchestration service automatically orchestrates dynamic multiple party, multiple media communications. A customer expresses his or her communications needs in the form of a high-level goal or goals. A goal-based search finds a combination of building block predicates that can be used to satisfy the customer's needs. In conjunction with the search process, the mechanism uses the SIP OPTIONS request or presence information to actively query device status and capabilities during the search. This enables the search to actively explore the communications environment at runtime. Once a solution is found, the necessary parties can be contacted, resources can be provisioned, and the multiple media, multiple user collaboration/conference can be initiated.

Abstract: A system and method for instrumentation of software, the software comprising a set of instructions (program or code) which are executable on a processor of a system, for example a computer system. A location in the instruction to insert a probe is first identified. The instruction is replaced with the probe by copying the instruction to a predefined location. The instruction is executed in the kernel space. A first exception is generated upon encountering the probe and calling a first exception handler, and the first exception handler is configured to call an instrumentation routine. A second exception is generated when the instrumentation routine encounters an error and calling a second exception handler, recovering from the exceptions and returning to a sane state to continue normal execution of the instruction.
