step 2.5.3, judging whether all ports of the current switch have destination nodes or not, and executing step 2.5.4 if the destination nodes exist; if no destination node exists, go to step 2.5.7;
step 2.5.4, finding the switch directly connected with the current switch and pressing the switch into a temporary switch stack;
step 2.5.5, popping up a switch, judging whether the switch is empty, and executing step 2.5.2 when the switch is empty; step 2.5.6 is performed when not empty;
step 2.5.6, determining the path as an unreachable path;
and step 2.5.7, the path finding is successful, and the path is saved.
7. A TTE network remote management system is characterized by comprising a unified information distribution mechanism and processing mechanism module, a management information conflict detection algorithm module and a node automatic detection and virtual link routing algorithm module;
the unified information distribution mechanism and processing mechanism module is used for operating a TTE network remote management data protocol and carrying out a one-to-many client-server communication mode; the client side carries out an information distribution process, and the server side carries out an information processing process;
the management information conflict detection algorithm module is used for carrying out conflict detection on management data in an information distribution process by a client;
the node automatic detection and virtual link path-finding algorithm module is used for the server side to execute the command of managing data in the information processing flow; and automatically detecting configuration information required by the nodes according to the management data and the virtual link information, calculating the positions and configuration parameters of the nodes according to the identification ID of each node and the virtual link information, and determining the path correctness of the data routing.
8. A computer device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of a TTE network remote management method according to any one of claims 1-8 when executing the computer program.
9. A computer-readable storage medium storing a computer program, wherein the computer program when executed by a processor implements the steps of a TTE network remote management method according to any one of claims 1-8.
