Deterministic Networking (DetNet) is a new network architecture proposed by IETF DetNet working group for industrial Internet of Things and other application scenarios. Its communication service with high reliability and low delay needs multi-path nonoverlapping routing algorithm. Because it is different from existing routing algorithms on the Internet, it is an important subject to study routing algorithms that meet requirements of DetNet. Based on routing characteristics of DetNet, we studied a multi-routing algorithm - Bhandari algorithm. Aiming at the problem that the algorithm cannot calculate nonoverlapping routes in some cases, we improve the algorithm, then we also make the improved algorithm more efficient by introducing Tarjan algorithm. The improved algorithm is verified and tested in the simulation environment and results show the effectiveness of the improved algorithm.
