Description
Technical Field
The invention relates to the technical field of internet, in particular to a resource acquisition method and system based on a block chain network.
Background
The working principle of the current cloud distribution system is a mode of 'near client cache' plus 'back source'. The near client cache refers to that nodes in the cloud distribution system are distributed at a place close to the client from the geographical position, and website contents to be accessed by the client are cached. The acquisition of the original content to be cached is realized through 'returning to the source', that is, the cloud distribution node replaces the client to access the source station, and acquires the corresponding content/resource from the source station. Since the source stations are generally distributed less geographically and are located farther from the client, the cache nodes of the widely distributed cloud distribution system provide a function of accelerating access to the website.
However, since the node in the cloud distribution system is closer to the client, it means that the node in the cloud distribution system is as far away from the source station as the client. The problem that the speed of accessing the source station by the client is low also exists when the node in the cloud distribution system accesses the source station. Furthermore, the performance of the source station is generally poor (because the server resources are not as much as the nodes in the cloud distribution system), and the simultaneous access of the source station by the nodes in the cloud distribution system may cause the source station to be paralyzed.
There are many existing methods for solving the back-source problem of the CDN, but all the core methods are really thought to try to reduce the number of accesses to the source station, for example, a relatively common "back-source speed limit" refers to a limit that the CDN node sends a back-source request when returning to the source. The reason is that the number of CDN nodes is large, and the source station generally has only limited resources to provide services to the outside. Therefore, the service carrying capacity of the source station is much smaller than the back-to-source sending capacity of the CDN network (for example, the CDN network is larger than the source station in both the two dimensions of the request number and the request frequency). In order to prevent the source station from failing to provide normal service due to a large number of back sources of the CDN, the CDN node limits the back sources, i.e., "back source speed limit". Whether the request comes back to the source or not when reaching the CDN node is judged, speed limit threshold value checking is firstly carried out, the request exceeding the threshold value is suspended and cannot come back to the source, and response delay is increased.
Therefore, a method and system that can solve the above problems are needed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
In order to solve the problems that in the prior art, a cloud distribution network node server is slow in returning to a source, and a large number of nodes in a cloud distribution system access a source station at the same time, which may cause the source station to be paralyzed, the resource acquisition method and system based on the block chain network of the invention provide a method for acquiring resources quickly based on the block chain network. The method comprises the steps that the characteristics of a block chain network are utilized, resources of a source station are stored on each node server of the block chain network, and the problem of performance bottleneck of the source station is solved; and accessing a cloud distribution network between the blockchain network and the client to solve the problem that resource retrieval cannot be performed in the blockchain network by using the URL in the client request.
In the resource acquisition method and system based on the block chain network, a unique retrieval identifier associated with a URL is inquired on a cloud distribution network node server through the URL in a client request, if the associated unique retrieval identifier is inquired, the unique retrieval identifier is sent to the node server of the block chain network, and the block chain network node server retrieves the associated resource through the unique retrieval identifier and sends the resource to the cloud distribution network node server. Because there are a plurality of node servers of the blockchain network and there may be a blockchain network node server closer to the cloud distribution network node server that receives the client request, the cloud distribution network node server does not need to go to a source station that is farther away to acquire resources, but acquires resources from the closer blockchain network node server. Therefore, the problems of long distance from a source station and slow source return in the prior art can be solved. In addition, as the number of node servers in the blockchain network is large, each cloud distribution network node server selects the blockchain network node server with a short distance without returning to the source to obtain resources, and therefore the problem that the source station is possibly paralyzed when a large number of nodes in the cloud distribution system access the source station at the same time is solved.
The invention provides a resource acquisition method based on a block chain network, as shown in fig. 1, the method comprises the following steps:
The cloud distribution network node server stores the incidence relation between the URL of the resource received from the source station and the unique retrieval identifier, when the cloud distribution network node server receives a request for the resource, if the associated unique retrieval identifier can be inquired based on the URL in the request, the cloud distribution network node server indicates that the resource corresponding to the URL is stored in the node server of the blockchain network, and if the URL cannot be inquired, the cloud distribution network node server indicates that the resource corresponding to the URL is not stored in the node server of the blockchain network, and the resource needs to be obtained back to the source.
Since the blockchain network node server may be closer to the cloud distribution network node server that receives the request, if the cloud distribution network node server can acquire resources from the closer blockchain network node server, the problem of slow resource acquisition back to the source can be avoided. In addition, as the number of the node servers of the block chain network is large, the problem that the source station is paralyzed because a large number of node servers access the source station at the same time can be avoided. In addition, due to the characteristics of the blockchain network, the URL in the client request cannot be identified by the blockchain network node server, that is, the corresponding resource stored in the blockchain network node server cannot be retrieved through the URL, so that a cloud distribution network is arranged at the front end of the blockchain network, the unique retrieval identifier associated with the URL is inquired through the association relationship between the URL stored in the cloud distribution network node server and the unique retrieval identifier, and thus, the URL which cannot be identified by the blockchain network node server is converted into the unique retrieval identifier which can be identified so as to retrieve the resource corresponding to the URL, and the corresponding resource can be rapidly acquired.
It should be noted that, after receiving a request for a resource from a client, the cloud distribution network node server generally first determines whether the resource is cached locally, and if so, directly returns the resource to the client that sent the request.
The method further comprises, before step 101, performing step 1011: a node server in the block chain network receives resources from a source station and sends the received resources to all or part of the node servers in the block chain network; a node server in the block chain network generates a unique retrieval identifier corresponding to the resource, and sends the association relation between the unique retrieval identifier and the resource to all or part of the node servers in the block chain network.
Since there may be node servers in the blockchain network that cannot store resources, in this case, the resources can only be backed up on a portion of the node servers.
In order to solve the problem of source station paralysis possibly caused by returning a large number of node servers to the source to acquire resources, the resources of the source station are stored redundantly on the blockchain network node servers, so that a large number of cloud distribution network node servers can acquire the resources from the scattered blockchain network node servers, and the problem of performance bottleneck of the source station is solved. In addition, the characteristics of the blockchain network itself may ensure that resources on which the source station is published are not tampered with maliciously.
In step 1011, after receiving the resource from the source station, a node server in the blockchain network performs redundant storage on all or a part of the node servers in the blockchain network by using its own consistency algorithm. The consistency algorithm can be implemented according to the prior art, and is not described in detail herein. A node server of the blockchain network may generate unique search identifiers corresponding to the respective resources and store associations of the respective resources with the corresponding unique search identifiers. Here, the resource is in a one-to-one correspondence with the unique search identifier. The node servers of the blockchain network may store associations of resources to unique retrieval identifiers in the form of lists. The blockchain network node server generating the unique retrieval identifier sends the association relation to each node server in the blockchain network, so that each blockchain network node server can retrieve corresponding resources locally when receiving the unique retrieval identifier from the cloud distribution network node server, and therefore access of a client to the resources is accelerated.
The step 1011 further includes: at least one node server in the blockchain network sends an association of a unique retrieval identifier with a resource to a source station.
Here, the blockchain network node server that transmits the association relationship is not limited to the blockchain network node server that generates the unique search identifier, and the association relationship is backed up and stored in all or a part of the node servers of the blockchain network, and therefore, the node servers that store the association relationship can transmit the association relationship to the source station.
The method further comprises performing step 1012 between step 1011 and step 101: the source station receives the incidence relation between the unique retrieval identifier and the resource, generates incidence relation information between the URL of the resource and the unique retrieval identifier based on the URL corresponding to the resource, and sends the incidence relation information between the URL of the resource and the unique retrieval identifier to the cloud distribution network node server.
The source station needs to associate the URL of the resource with the corresponding unique retrieval identifier, and send the association relationship to each node server of the cloud distribution network, so that the cloud distribution network node server can query the corresponding unique retrieval identifier based on the association relationship between the URL and the unique retrieval identifier after receiving the URL in the request. The source station thus needs to obtain an association relationship between the unique search identifier and the resource, and thereby associate the URL of the resource with the unique search identifier based on the association relationship.
The method further comprises performing after step 102: after receiving the unique retrieval identifier sent by the cloud distribution network node server, the block chain network node server queries and acquires the resource corresponding to the unique retrieval identifier based on the incidence relation between the unique retrieval identifier and the resource, and sends the resource to the cloud distribution network node server.
All or part of the node servers of the block chain network store resources issued by the source station, so that the node servers can query the resources corresponding to the unique retrieval identifier after receiving the unique retrieval identifier and send the resources to the cloud distribution network node server, so that the cloud distribution network node server can acquire the resources quickly and send the resources to a requesting client.
If the resource corresponding to the unique search identifier is not locally stored in the blockchain network node server that receives the unique search identifier from the cloud distribution network node server, the blockchain network node server acquires the corresponding resource from the other blockchain network node servers in which the resource is stored by using the characteristics of the blockchain network itself, and returns the resource to the cloud distribution network node server that transmitted the unique search identifier.
Sending 102 the unique retrieval identifier associated with the URL to a node server in the blockchain network includes: based on the principle of geographical location proximity access, selecting at least one node server in the blockchain network, and sending a unique search identifier associated with the URL to the selected blockchain network node server.
In this step, the node server of the blockchain network with a closer geographical position is selected to acquire resources more quickly, so that an effect of accelerating access is achieved. The specific manner of selecting the blockchain network node server with a closer geographical position may be implemented by a method in the prior art, and is not described herein again.
