Abstract: Reducing network congestion using a load balancer is described. The load balancer receives network traffic for processing work for a delay-sensitive application. The load balancer is coupled with multiple application instances executing on compute nodes that are each capable of processing the work. The load balancer determines from the network traffic whether there is an indication of network congestion. If there is an indication of network congestion, the load balancer selects one of the application instances for processing the work based at least in part on reducing the network congestion. The load balancer causes the work to be processed at the selected application instance.

Abstract: A software monitoring of real-time services arrangement (100) comprising a controller (101) configured to: receive (310) data relating to real-time performance (211) from one or more real-time services (215), the data relating to real-time performance (211) indicates a performance of the real-time services (215); generate (330) a performance image (245) wherein the data relating to real-time performance (211) for an associated real-time services (215) indicates an image characteristic in an area of the performance image (245) corresponding to the associated real-time services (215); perform (340) image analysis (250) on the performance image (245); and select (350) an action for achieving a desired result based on the image analysis.

Abstract: A software monitoring arrangement (100) comprising a controller (101) configured to: a) receive a software code module (215); b) introduce a plurality of probes (211) into the software code module (215), each probe (211) being arranged to provide output (212) when executed; c) execute the software code module (215) generating an image log file (213) based on the output (212) of the probes (211); d) provide image analysis (221) of the image log file (213); e) provide an indication (222) of an expected behavior based on the image analysis (221); f) receive an indication (216) of an actual behavior; g) compare the expected behavior as indicated by its indicator (222) to the actual behavior as indicated by its indicator (216); and provide an alert (231) based on the comparison.

Abstract: A physical network node controls allocation and/or deallocation of resources of an interconnected hardware infrastructure. The physical network node determines a number of requests currently queued at a first service node of a plurality of serially-connected service nodes at a current time. The plurality of serially-connected service nodes supports a packet flow using resources of the interconnected hardware infrastructure. The physical network node also determines a packet flow rate of the packet flow into the first service node. The physical network node also determines a future time to control allocation or deallocation of a resource of the interconnected hardware infrastructure to a second service node of the plurality of serially-connected service nodes based on the determined number of requests and the determined packet flow rate. The physical network node controls allocation or deallocation of the resource to the second service node at the future time.
