Efficient resource allocation method for hitless redundancy switching technology at multiple sites

Abstract

For transmitting video or financial transaction information, communication interruption must be short, so hitless redundancy switching (HRS) technology is a useful solution. However, when this technology is used in multiple sites, a large amount of resources is required for HRS devices to communicate. In this paper, we propose an efficient resource allocation method and demonstrate that it can reduce resource usage by 97% in a numerical simulation.
