The utility model discloses a real-time data routing device, which belongs to the technical field of routing devices and comprises an outer shell, a data routing system is mounted in the outer shell, a plurality of uniformly distributed butt joint holes are arranged at the rear end of the outer shell, a baffle is arranged between adjacent butt joint holes, and the baffle is fixedly connected with the outer shell. A matched movable butt joint assembly is slidably installed in the butt joint hole, a data interface is fixedly installed at the end, close to the data routing system, of the movable butt joint assembly, the data interface is electrically connected with the data routing system through a data connecting line, and an auxiliary plate is fixedly installed at the upper end of the movable butt joint assembly. A plurality of moving holes matched with the auxiliary plates are formed in the upper end of the outer shell, through the design of the movable butt joint assembly, connection between the connector and the data interface is more stable and not prone to loosening or falling off, the real-time transmission stability of data is effectively guaranteed, and the situation that data transmission is interrupted due to the connection problem is reduced.

The application discloses a routing protection method based on hop number dependence and partial order calculation, which fully utilizes partial order routing calculation and hop number to solve the routing protection task. Firstly, all paths are divided into atomic comparison paths and non-atomic comparison paths, all paths of source and destination nodes are divided into incomparable path sets and comparable path sets through partial order routing calculation, and path consistency forwarding is ensured by using the cumulative calculation mode of the next hop of the bifurcation node; secondly, the comparable path set is pruned through a hop number pruning strategy, an intersection point set and a pruning strategy combined with hop number; finally, a candidate path set of a Top1 path and a candidate path set of a Top2 path are obtained, and particularly, the application reduces the time complexity of processing paths through a double stack structure. In a real network topology, compared with the existing common routing protection scheme, the application improves the protection rate of the Top1 path, and can guarantee that the Top2 path has better performance.
