Embodiment Construction

[0038] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] see figure 1 As shown, an embodiment of the present invention provides a nearby scheduling method for a content distribution network, including the following steps:

[0040] S1. Divide the country into nodes according to administrative regions, and set the node ID according to the geographical proximity; if the main feature is the province number + area code, it is represented as the node ID, such as Hubei, the province number is 203, and Yichang, the area code is 0717, then Yichang’s The node ID is 2030717;

[0041] S2. Establish the corresponding relationship between node ID and IP range, each node ID corresponds to a different IP range; that is, it can be determined that a certain IP belongs to only one node through the IP address library;

[0042] S3. When the user requests to access the network service, obtain the source IP addres...

Abstract

The invention discloses a method and system for nearby scheduling of a content distribution network, and relates to the technical field of CDN scheduling. The invention divides the country into nodes according to administrative regions, sets node IDs according to geographical location proximity, and establishes a corresponding relationship between node IDs and IP ranges ; When the user requests to access the network service, obtain the source IP address of the user request, and obtain the user request source node according to the corresponding relationship between the node ID and the IP range; calculate the similarity between each node ID and the user request source node ID, and compare the similarity The smallest node acts as the nearest node, and dispatches user requests to the nearest node. Since area codes are naturally geographically close in nature, it is possible to implement dispatching near the user's geographical location. The nodes corresponding to the IP address library do not need to correspond to the nodes actually deployed on the existing network. When a node is newly deployed or deleted, the IP address library does not need to be adjusted, but the similarity calculation is performed and the nearest node is scheduled.

Description

technical field [0001] The invention relates to the technical field of CDN scheduling, in particular to a method and system for nearby scheduling of a content distribution network. Background technique [0002] In the CDN system, in order to reduce the delay, increase the access rate, and increase the user experience, it is necessary to schedule the user's request to the best node. Generally speaking, the node with the closest geographical location is the node with the best access quality. There are two options: [0003] Method 1: Static Scheduling [0004] Establish an IP address library, specify the node to be scheduled in the IP range, and decide which node to schedule based on the user's source IP. This method is relatively rigid and not flexible enough. When adding or deleting nodes, the IP address library needs to be adjusted; or when a node fails, only the default node can be scheduled, and dynamic nearby scheduling cannot be realized. [0005] Method 2: Dynamic Sc...
