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.

Handover in a telecommunications system with distributed processing

A downlink physical layer processing system includes a transport block segmentation processor that receives a transport block and generates segmented blocks from the transport block, an encoder that encodes the segmented blocks and forms encoded blocks, a mapping processor that maps the encoded blocks to symbols corresponding to resource elements to generate mapped symbols for transmission over a transmission medium, and a transmission signal generator that processes the mapped symbols to generate transmission signals for transmission over the transmission medium. The mapping processor maps the encoded blocks to the symbols in response to a control signal generated by the transmission signal generator. The encoder thereby operates in response to timing of data received by the encoder while the mapping processor operates in response to timing of processing of symbols by the transmission signal generator.
