Problems solved by technology

But the reality is that the nodes with the closest distance may not be the fastest nodes for users to access
Especially when there are no nodes in the user's area, it is unreasonable to simply use the spatial distance to access
This situation is especially obvious in some small countries in the world, because the countries in some places are relatively dense, and CDN manufacturers may not be able to build nodes in every country, and the node quality service of each country may be excellent for the country, but external The quality may be very poor. For example, there is no CDN node in a certain country, but the service quality of the CDN node deployed in the nearest neighboring country may be very poor, while the service quality of the CDN node deployed in another country farther away may be poor. Very good, in this case, if you use the spatial distance method to choose the nearest access, it will seriously affect the user's online experience
For nodes with similar spatial distances, random scheduling will show that the access speed is good and bad on the user side.

Embodiment 1

[0037] This embodiment provides a CDN detection processing method, such as figure 1 As shown, including the following detection process:

[0038] Step 110, delivering one or more IP addresses in the first IP segment to multiple CDN nodes;

[0039] In this embodiment, the first IP segment is an IP segment used by the terminal in the IP database, and one or more IP addresses in the first IP segment are IP addresses of the terminal. That is to say, in this embodiment, the link from the CDN node to the user terminal is detected, and the CDN node to be preferentially scheduled is selected for the user terminal in the first IP segment, so as to speed up the first stage in the actual access process of the user terminal above. access time. However, this application can also be used to detect the link from the CDN node to the source station, so as to speed up the access time of the second stage in the actual access process of the user terminal.

[0040] The first IP segment in this ...

Embodiment 2

[0084] In related technologies, CDN scheduling is to find the corresponding IP segment according to the IP address carried in the access request, and judge whether there is a CDN node deployed in the user's area according to the specific node distribution, and if so, select the deployed CDN node and return For users to access, and when multiple CDN nodes are deployed in the same area, it is necessary to select the CDN node of the same operator according to the operator corresponding to the IP segment, and the scheduling efficiency is not high.

[0085] This embodiment provides a scheduling method of a content distribution network CDN, such as image 3 shown, including:

[0086] Step 210, the scheduling node of the CDN receives the access request of the user terminal, and determines the information of the first IP segment where the IP address is located according to the terminal IP address carried in the access request;

[0087] Step 220, the scheduling node directly searches ...

Embodiment 3

[0097] This embodiment provides a detection processing device for a content distribution network CDN, including a CPU and a memory, wherein:

[0098] The memory is used to store program codes;

[0099] The CPU is used to read the program code in the memory, and execute the following link detection method: sending one or more IP addresses in the first IP segment to multiple CDN nodes; receiving the multiple CDN nodes The link detection result reported, the link detection result including the delay information of the CDN node accessing the IP address; and according to the delay information, selecting the first CDN node from the plurality of CDN nodes The priority scheduling node of the IP segment.

[0100] The link detection method described above may also be the link detection method described in any one of the first embodiment.

[0101] Let's illustrate with a few examples in the application.

Abstract

A detection processing and scheduling method of a content distribution network, a corresponding apparatus and nodes are disclosed. A detection processing apparatus issues one or more IP addresses in afirst IP segment to a plurality of CDN nodes and receives a link detection result reported by the plurality of CDN nodes. The link detection result comprises information of time delay when the CDN nodes access the IP addresses. According to the time delay information, a priority scheduling node of the first IP segment is selected from the plurality of CDN nodes. The scheduling node directly searches the priority scheduling node of the first IP segment according to information of the first IP segment and the information of the searched priority scheduling node is returned to a user terminal. In the invention, a problem that service quality is not guaranteed when ''near access'' is performed on the CDN nodes can be avoided.

Description

technical field [0001] The present invention relates to a content delivery network (CDN: ContentDelivery Network), and more specifically, to a detection processing and scheduling method of a content delivery network and corresponding devices and nodes. Background technique [0002] The basic idea of ​​CDN is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. By placing a layer of intelligent virtual network based on the existing Internet based on node servers placed everywhere in the network, the CDN system can real-time according to the network traffic and the connection of each node, the load status, the distance to the user and the response time, etc. The comprehensive information redirects the user's request to the service node closest to the user. Its purpose is to enable users to obtain the required content nearby, solve the congesti...
