Abstract:
The present invention provides systems for improved quality of service and traffic management in network routers and other devices. This is achieved, according to one aspect of the invention, by coupling a plurality of queue processors to a plurality of input interfaces that receive data from one or more respective network connections. Each queue processor, in coordination with an associated scheduler that schedules dequeing of data from one or more queues, maintains the quality of service levels with respect to throughput, and delivers the data for a particular output context based on priority to a respective output interface. The output interface is coupled to the plurality of queue processors and transfers the data to one or more respective network connections. In addition, a plurality of output interfaces can be coupled to respective pluralities of queue processors for transferring data therefrom to one or more destination network connections. Packets, cell, datagrams and so forth passing through the router are disassembled and marked with one or more priority levels. Prior to exiting the router they re reassembled (based on those priorities, inter alia) into their constituent forms for continued routing on the network.
