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 non-overlapping routing algorithm. Because it is different from the existing routing algorithms on the Internet, it is an important subject to study the routing algorithms that meet the requirements of DetNet. Based on the routing characteristics of DetNet, we study a multi-routing algorithm -- Bhandari algorithm. Aiming at the problem that the algorithm can not calculate non-overlapping routes in some cases, we improved the algorithm, then we also make the improved algorithm more efficient by introducing Tarjan algorithm. The algorithm is verified and tested in the simulation environment and results show the effectiveness of the improved algorithm.
