Implementation of a fast failure recovery method considering load distribution for network slicing

In recent years, network slicing technology that can provide virtual networks according to various service re-quirements has been attracted much attention. In this paper, we propose a load-balanced fast failure recovery method based on Multiple Routing Configurations (MRC) in communications using network slicing. MRC ensures path availability in the case of a link/node failure by preparing multiple backup routing configurations in advance. In this paper, we implement MRC by considering the load of each node based on the amount of traffic that passes through it, which prevents unbalanced load after switching the routing configuration. We confirm that the load of nodes is equalized for each backup configuration by the proposed method. In addition, by evaluating the implementation using Mininet, we show that routing paths are ensured by adopting a backup configuration in the case of a failure.
