Communication apparatus and method of content router to control traffic transmission rate in content-centric network (CCN), and content router

摘要

A communication apparatus and method of a content router control a traffic transmission rate in a content-centric network (CCN), and the content router. In the communication method and the content router, a congestion of a network may be predicted, a warning signal indicating the congestion may be added to an interest packet, and the interest packet with the warning signal may be transmitted. Additionally, a traffic transmission rate may be controlled by adjusting a data packet transmission time based on a value of a marked field of a PIT. The PIT is set by receiving an interest packet to which a warning signal is added. Thus, the communication apparatus and method thereof provide reachability, while maintaining stability of network routing.

1. A communication method to control a traffic transmission rate in a content-centric network (CCN) in which a content router transmits an interest packet, the communication method comprising:
predicting whether traffic congestion occurs in the content router based on a rate of utilization of a pending interest table (PIT) of the content router; generating a warning signal indicating the prediction of traffic congestion occurring in the content router; adding the warning signal to an interest packet received from a previous node; and transmitting to a next node the interest packet to which the warning signal is added.
