Problems solved by technology

[0002] There are a large number of edge nodes for customers in the pcdn system. These edge nodes are either a common box or a common service point. Due to cost factors, the distribution of general edge nodes in the country is not enough, so a certain edge node may It is used by scheduling requests outside the province, and the stability of edge nodes is much worse than that of traditional CDN IDC room resources, so in the pcdn system, evaluating the availability of these edge nodes becomes an important technical link. If the edge node is no longer available and the node is used for scheduling, the scheduling request will fail, affecting the scheduling success rate index
At the same time, even if the node is available, the links from different geographic locations in adjacent provinces (regions) to an edge node may fail due to network delays and link problems
[0003] At present, the calling method of dispatching requests is carried out in a one-to-one way between nodes and central services. In the detection information, there are only two cases of available or unavailable indicators for line availability. The data detected by this method has a single result and the availability is not high. The problem
For example, the central service is in Beijing and the node is in Shanghai. This single scheduling method can only show that the scheduling request from the vicinity of Beijing has a high probability of success to the Shanghai node.
However, if a scheduling request in Zhejiang has insufficient nodes in this province, it is necessary to select a node in a neighboring province for scheduling. This detection method cannot reflect the availability of scheduling well.

specific Embodiment 1

[0028] A pcdn node evaluation method based on full-link detection of the present application, the scheduling request node makes a request to the central service, the central service sends a request to each detected node around the center with the scheduling request node as the center, and receives returned messages.

[0029] Around the scheduling request node, multiple detected nodes are selected from different directions, and the distance between each detected node and the scheduling request node is different, and the detected nodes are selected according to the direction and distance.

[0030] Set the distance index and multi-channel detection comprehensive availability index for each detected node, and then combine the central service’s central detection availability index for the detected node to calculate the path-weighted availability of each detected node, and use the value of the path-weighted availability index value, Select a detected node as a link node.

Abstract

The invention discloses a pcdn node evaluation method and terminal based on full-link detection, and the method comprises the steps: taking a scheduling request node as a center, searching detected nodes around the scheduling request node, calculating a distance index and a direction from each detected node to the scheduling request node, and a multi-path detection comprehensive availability index of the detected nodes; searching edge detection nodes around the detected nodes, combining directions, distances and multiple paths, calculating a multi-path detection comprehensive availability index of each detected node, obtaining a path weighted availability index of each detected node, and selecting a proper detected node as a link node according to the path weighted availability index; the scheduling success rate is improved.

Description

technical field [0001] The invention relates to the technical field of PCDN, in particular to a PCDN node evaluation method and terminal based on full-link detection. Background technique [0002] There are a large number of edge nodes for customers in the pcdn system. These edge nodes are either a common box or a common service point. Due to cost factors, the distribution of general edge nodes in the country is not enough, so a certain edge node may It is used by scheduling requests outside the province, and the stability of edge nodes is much worse than that of traditional CDN IDC room resources, so in the pcdn system, evaluating the availability of these edge nodes becomes an important technical link. If the edge node is no longer available and the node is used again for scheduling, the scheduling request will fail, affecting the scheduling success rate index. At the same time, even if the node is available, the link from different geographic locations in neighboring pro...
