Network path optimization method and system

A network path optimization method, comprising:

• in response to a network access request, computing and sending an optimal path having a path code and carrying a path parameter, wherein the optimal path is established between a plurality of nodes, and the path parameter comprises a path weight of a node and time elapsed for computing the optimal path;
• acquiring a parameter variation between the optimal path and a real path by analyzing the path parameter and a path tag, the path tag being added to the optimal path based on a variation of the real path, wherein the updating the optimal path and the path parameter based on the parameter variation comprises:
• analyzing a path parameter and a parameter variation between the nodes on the optimal path, determining node status, wherein the parameter variation comprises a delay ratio and a packet loss ratio;
• and
• adjusting the path weight of the node based on the node status.

A network path optimization system, comprising a control server, a plurality of network access terminals and a cluster of data processing terminals, the plurality of network access terminals constructing a network, the plurality of network access terminals being communicably connected to the control server and the data processing terminal cluster, and the control server being communicably connected to the data processing terminal cluster;
