Name Resolution Acceleration Method Based on Adaptive Timeout Interval Adjustment
When ICN based on name resolution supports mobility,since the time when the terminal after moving registers the mapping of its identifier and new address to the name resolution system is uncertain,network devices need to initiate multiple resolution queries to the name-resolution system until they obtain the new address corresponding to the mobile terminal's identifier,and use the new ad-dress as the destination address for data transmission.In the process of the multiple resolution queries initiated by the network devices to the name resolution system,it is necessary to design reasonable resolution query methods to reduce the latency for the network de-vices to get the new address.This paper proposes a resolution query acceleration method based on adaptive timeout interval adjustment,which uses the exponentially-weighted moving average of RTT to adaptively adjust the timeout interval.Experimental results show that the proposed method reduces the average resolution query latency by 12.48%compared to the method of adaptively adjusting the time-out interval using the estimation method of the retransmission timeout in TCP of RFC6298,and by 21.92%compared to the method u-sing a constant timeout interval.
