Abstract
Ethernet is the very successful technology in private local area network. Therefore, we can obtain the advantage to reduce network overhead due to such as protocol translation when to apply Ethernet to the public backbone network. However, in order to do that, it is required to restore the network within 50msec when link failure occurs, in order to provide seamless connections to end users. Currently, ITU-T standardized the automatic protection switching (APS) based Ethernet protection switching system. In this paper, we propose the improved Ethernet protection switching system to minimize the number of Ethernet frames lost when the network is restored from the failure. The proposed mechanism is analyzed by using simulation based on ns-2 and numerical results show that the proposed one provides superior performance.
