A multi-process scheduler applies a joint optimization criterion to jointly schedule multiple processes executed on a shared processor. The scheduler determines, for each one of a plurality of processes having a predetermined processing time, at least one of an expected arrival time for input data and required delivery time for output data. The scheduler jointly determines process activation times for the processes based on said arrival/delivery, and the processing times, to meet a predetermined joint optimization criterion for the processes. The processes are scheduled on the shared processor according to the jointly determined activation times to minimize queuing delay.

Joint scheduling of multiple processes on a shared processor

In a system () handles plural communication channels (), pre-configured instrumentation code () is loaded into a common program memory. The instrumentation code () is used to generate a surveillance element (). The surveillance element () comprises multi-dimensional execution criteria and executable surveillance code configured to cause performance by a target processor unit of a surveillance element-specified surveillance action. The surveillance element () is executed by the target processor unit with respect to the respective subset of plural communication channels and permits continued transport of data over the plural communication channels.

Non-instrusive network surveillance and characterization

A switch that interconnects networks provides a scheduling algorithm that determines a number of active events to be processed by a processor in the switch. The active events involve processing of bearer traffic. A schedule tailored to the number of active events is generated. In response to a change affecting the schedule, the schedule is modified. The active events are processed by the processor according to the modified schedule.
