Resource scheduling method and system

A network device, comprising:

• at least one processor;
• and
• a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein
• the instructions, when executed by the at least one processor, cause the at least one processor to perform a resource scheduling method comprising:
• collecting in cycles, by a resource scheduling system, target client available bandwidths of node servers corresponding to a target client in a target area and a real-time bandwidth demand of the target client in the target area;
• determining, by the resource scheduling system, a target node server in the node servers according to the real-time bandwidth demand, bandwidth costs of the node servers, and the target client available bandwidth;
• and
• scheduling, by the resource scheduling system, a service access request of the target client in the target area to the target node server;
• wherein determining, by the resource scheduling system, a target node server in the node servers according to the real-time bandwidth demand, bandwidth costs of the node servers, and the target client available bandwidth comprises:
• selecting in succession, by the resource scheduling system, bandwidth carrying nodes in the node servers in order of the bandwidth costs from low to high;
• when a sum of target client available bandwidths in selected bandwidth carrying nodes is greater than the real-time bandwidth demand, determining, by the resource scheduling system, the bandwidth carrying nodes as the target node server.

A non-transitory computer readable storage medium configured to store a computer program, wherein the computer program when executed by a processor, implements a resource scheduling method comprising:

• collecting in cycles, by a resource scheduling system, target client available bandwidths of node servers corresponding to a target client in a target area and a real-time bandwidth demand of the target client in the target area;
• determining, by the resource scheduling system, a target node server in the node servers according to the real-time bandwidth demand, bandwidth costs of the node servers, and the target client available bandwidth;
• and
• scheduling, by the resource scheduling system, a service access request of the target client in the target area to the target node server;
• wherein determining, by the resource scheduling system, a target node server in the node servers according to the real-time bandwidth demand, bandwidth costs of the node servers, and the target client available bandwidth comprises:
• selecting in succession, by the resource scheduling system, bandwidth carrying nodes in the node servers in order of the bandwidth costs from low to high;
• when a sum of target client available bandwidths in selected bandwidth carrying nodes is greater than the real-time bandwidth demand, determining, by the resource scheduling system, the bandwidth carrying nodes as the target node server.
