Abstract: A head of line (HOL) blocking count value, which is directly proportional to the committed traffic load for traffic flow through an output port within a multi-stage switch mesh, is computed for a path by adding the values associated with all output ports within the path. In selecting a route, all paths from the source to the destination are identified and sorted by head of line blocking count value. Rather than selecting a path based on traffic load, the path having the lowest head of line blocking count value and sufficient capacity for the requested traffic is selected, with selection between paths having equal head of line blocking count values being made based on traffic load.

Abstract: Disclosed herein are apparatus and methods for sharing resources in a real-time processing system. According to an advantageous embodiment, a real-time processing system is introduced that (i) executes application, kernel and interrupt-service processes utilizing processor resources selectively allocated thereto and (ii) handles interrupt-service requests received from interrupt sources associated with the real-time processing system. The real-time processing system comprises a controller that operates to monitor resource-utilization limits associated with each of the interrupt sources.
