Abstract

Methods and system architectures are disclosed for controlling the processing of data packets in a packet data router configured to support a plurality virtual router instances, with each virtual router instance storing received data packets in one or more respective ingress data queues. In a first exemplary aspect of the disclosure, the packet flow rates of one or more ingress data queues associated with a first virtual router instance are increased or decreased based on current operating conditions of the router. In a another exemplary aspect of the disclosure, the packet flow rates of one or more ingress data queues associated with a first virtual router instance are increased, while the packet flow rates of one or more ingress data queues associated with a second virtual router instance are decreased, respectively, in response to current operating conditions of the router, e.g., current processor or memory utilization.
