TRACKING QUEUING DELAY AND PERFORMING RELATED CONGESTION CONTROL IN INFORMATION CENTRIC NETWORKING

摘要

A network device that performs information centric networking (ICN) in an ICN network receives an Interest from a consumer as the Interest traverses an Interest path to a data responder. The Interest requests data by name and indicates an accumulated Interest queuing delay experienced by the Interest on the Interest path. The network device enqueues the Interest to an Interest queue and dequeues the Interest from the Interest queue, and determines a local Interest queuing delay between the enqueing and dequeuing. The network device increases the indicated accumulated Interest queuing delay by the local Interest queueing delay, and forwards the Interest along the Interest path. The network device receives a Data packet satisfying the Interest as the Data packet traverses the Interest path in reverse. The network device increases an accumulated Data queueing delay indicated in the Data packet, and then forwards the Data packet to the consumer.

1. A method comprising:
at a network device among network devices configured to perform information centric networking (ICN) in an ICN network:
receiving an Interest from a consumer as the Interest traverses an Interest path to a data responder, the Interest requesting data by name and indicating an accumulated Interest queuing delay experienced by the Interest on the Interest path;enqueuing the Interest to an Interest queue and dequeuing the Interest from the Interest queue;determining a local Interest queuing delay between the enqueing and dequeuing;increasing the indicated accumulated Interest queuing delay in the Interest by the local Interest queueing delay; andforwarding the Interest along the Interest path.
