Description

Content distribution method, device and system of content distribution network

Technical Field

the present invention relates to the technical field of content distribution networks, and in particular, to a content distribution method, device and system for a content distribution network.

Background

With the rapid development of the internet and the unified trend of markets such as global commodity service and the like being more and more obvious, the demand that various internet sites need to be rapidly accessed by global or whole-Network users is more and more strong, and a Content Delivery Network (CDN) service provides internet bottom layer technical support for such scenes.

For most users, the CDN will provide an available site as a source site, and after a site that needs acceleration accesses the CDN service, a user requests to access the CDN node, and if the cache is not hit, the user returns to the source site of the user, obtains content, and caches the content at the CDN node. The mode is influenced by factors such as site service forms, CDN cache strategies, multi-tenant cache resource competition and the like, and still may bring very large bandwidth cost to the user source station. Therefore, the CDN side provides Object Storage Service (OSS) Storage Service instead of the user source station function, and is also favored by many CDN users.

as shown in fig. 1, in a scenario where an OSS storage service is provided on a CDN side, a CDN user generally uploads new content to the OSS storage service periodically, however, an OSS is generally deployed centrally and takes over the task of uploading a large amount of user content, and the uploading time may be long, so that timely overall network delivery of new content on a site is affected.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

First, some terms or terms appearing in the description of the embodiments of the present invention are applicable to the following explanations:

The CDN is called a Content Delivery Network, i.e., a Content Delivery Network. The basic idea is to avoid bottlenecks and links possibly influencing data transmission speed and stability on the Internet as far as possible, so that content transmission is faster and more stable. By placing node servers at various positions of the network to form a layer of intelligent virtual network on the basis of the existing internet, the CDN system can redirect the request of a user to a service node closest to the user in real time according to network flow, connection of each node, load condition, distance to the user, response time and other comprehensive information. The method aims to enable the user to obtain the required content nearby, solve the problem of congestion of the Internet network and improve the response speed of the user for accessing the website.

The Object Storage Service (OSS) is a cloud Storage Service with high volume, safety, low cost and high reliability. The user can upload and download data at any time, at any place, on any internet device. Based on the OSS, the user can build various multimedia sharing websites, network disks, personal and enterprise data backup and other large-scale data-based services.

Example 1

according to the embodiment of the invention, the embodiment of the content delivery method of the content delivery network is also provided, and the target content to be delivered by the user of the content delivery network is obtained by uploading the target content to be delivered by the user of the content delivery network to the target CDN node, namely delivering the target content; uploading target content to a target CDN node; after the target content is detected to be uploaded to the target CDN node, the target content is released, the problem that the target content is released only after the target content is uploaded to the centrally deployed OSS storage service is avoided, the technical effect of uploading the target content by CDN users is improved, and the technical problem that the CDN users upload new resources at a low speed due to the fact that the CDN users are distributed in the whole network and the OSS storage service is centrally deployed and cannot provide fast uploading link guarantee for all areas is solved.

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.

Specifically, the present invention provides a content distribution method of a content distribution network as shown in fig. 2. Fig. 2 is a flowchart of a content distribution method of a content distribution network according to an embodiment of the present invention.

Step S202, target content to be issued of the user is obtained.

For example, a user of the content distribution network wants to issue a taken early morning photo on a microblog, and the early morning photo is the target content. It should be noted that, the target content in the embodiment of the present invention may be a photo, a video, and text information, and is not limited herein.

And step S204, uploading target content to the target CDN node.

For example, a morning photo is uploaded to the target CDN node. In order to increase the speed of uploading the early morning photos, optionally, in the method for content delivery of the content delivery network provided by the present invention, before uploading the target content to the target CDN node, the method further includes: screening CDN nodes closest to a user network from a plurality of CDN nodes; and taking the CDN node closest to the user network as a target CDN node.

For example, when a video to be delivered by a beijing CDN user is acquired, a CDN node of an area to which beijing belongs, which is closest to the CDN user network, is acquired as a target CDN node, and the video is uploaded to the CDN node of the area to which beijing belongs. By selecting the CDN node closest to the CDN user network as the target node, the speed and efficiency of uploading the target content are improved.

Step S206, after detecting that the target content is uploaded to the target CDN node, delivering the target content.

For example, the target content is a video, and the video is published after the video is detected to be uploaded to the target node. After the video is published, others can view the video.

Because the CDN node has a limited cache space, in order to store the content uploaded by the user for a longer time, optionally, in the method for delivering content in the content delivery network provided by the present invention, after detecting that the target content is uploaded to the target CDN node, the method further includes: and uploading the target content to an Object Storage Server (OSS).

through the scheme, the target content is uploaded to an Object Storage Server (OSS).

It should be noted that, in the embodiment of the present invention, after it is detected that the target content is uploaded to the target CDN node, the target content is released, and the target content in the CDN node is uploaded to the OSS in an asynchronous manner, that is, it is not necessary to wait until the target content in the CDN node is uploaded to the OSS before the target content is redistributed, so that a speed of uploading a new content resource by a CDN user is increased.

Fig. 3 shows a flowchart of delivering the target content after detecting that the target content is uploaded to the target CDN node in the technical solution disclosed in step S206. As shown in fig. 3, the method specifically includes the following steps:

Step S302, based on the identification of the target CDN node, a link corresponding to the target content is generated.

For example, when a link corresponding to the target content is generated, the IP of the CDN node is a part of the URL.

step S304, embedding the link corresponding to the target content into the target content.

Step S306, the target content carrying the corresponding link is released.

Through the scheme, after the target content is released, other people can index to the target CDN node through the link corresponding to the target content so as to find the target content.

further, in the method for delivering content in a content delivery network provided by the present invention, generating a link corresponding to the target content based on the identifier of the target CDN node further includes: and generating a link corresponding to the target content based on the identifier of the target CDN node and the uploading time, wherein the uploading time is the time when the target content is uploaded to the target CDN node.

For example, the uploading time for uploading the target content to the target CDN node is 2018-4-23, 08: 00: 03, generating a link corresponding to the target content based on the IP of the CDN node and the upload time, that is, carrying information of the target CDN node and the upload time in the link corresponding to the target content.

Fig. 4 shows a flowchart of the distribution of the target content in the technical solution disclosed in the above step S306. As shown in fig. 4, the method specifically includes the following steps:

step S402, whether an HTTP request is received or not is detected, wherein the HTTP request is used for requesting to view the target content.

for example, a user waiting to view target content may trigger an HTTP request.

Step S404, when receiving the HTTP request, parsing the link corresponding to the target content to determine the uploading time of the target content.

Step S406, determining whether the time interval between the current time and the uploading time exceeds a preset time.

For example, the preset time is one day.

Step S408, when the time interval between the current time and the uploading time does not exceed the preset time, returning to the target CDN node to view the target content.

And step S410, returning to the OSS to check the target content when the time interval between the current time and the uploading time exceeds the preset time.

for example, if the preset time is one day, the user returns to the CDN temporary storage area to view the target content when the time interval between the current time and the upload time does not exceed one day. And under the condition that the time interval between the current time and the uploading time exceeds one day, returning the content to the OSS for viewing, namely returning the content after one day to the OSS.

Further, in order to ensure the security of the delivered content, in the method for delivering content in the content delivery network provided by the present invention, after generating a link corresponding to the target content based on the identifier of the target CDN node and the upload time, the method further includes: and encrypting the link corresponding to the target content.

The link corresponding to the target content is encrypted, so that the safety of the target content is ensured.

optionally, in the method for delivering content in a content delivery network provided by the present invention, after uploading the target content to an Object Storage Server (OSS), the method further includes: and deleting the target content in the target CDN node.

Through the scheme, after the target content is uploaded to an Object Storage Server (OSS), the target content is deleted in the target CDN node so as to release the cache space in the target CDN node, and other content can be cached subsequently.

optionally, in the method for content distribution in a content distribution network provided by the present invention, before uploading the target content to an Object Storage Server (OSS), the method further includes: detecting whether the current network is in the low peak period of the internet; and if the current network is in the peak period of internet surfing, executing the step of uploading the target content to an Object Storage Server (OSS).

bandwidth cost is saved by uploading to an Object Storage Server (OSS) during the peak of the internet.

As shown in fig. 5, in the schematic diagram of the whole process of the content delivery method of the content delivery network according to the embodiment of the present invention, a user uploads new content to a nearby CDN node and temporarily stores the new content in a temporary storage area on the CDN node; the user can immediately use the uploaded CDN node IP as a part of the URL (such as a source return URL parameter, an uploading time parameter and the like, and the parameters can be encrypted) to carry out CDN delivery. After the content on the CDN node is uploaded to the OSS in an asynchronous mode, deleting the content from the temporary storage area of the CDN node; to save bandwidth costs, asynchronous upload to OSS actions may be performed during bandwidth downtimes. After the user side APP or the site releases the new resource, the HTTP request aiming at the new resource is scheduled to the CDN node; and the CDN node judges whether the resource is returned to the OSS or the temporary storage area of the CDN node according to the uploading time parameter in the URL parameter.

It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the order of acts, as some steps may occur in other orders or concurrently in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases.
