Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The configuration file synchronization method provided by the embodiment of the application can be applied to an application environment shown in fig. 1, and can be realized by matching a server side with a plurality of clients with configuration file synchronization requirements. Wherein the client 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be located on a cloud or other network server. Alternatively, only two clients 102 are shown in fig. 1, and in a practical scenario, there may be a plurality of clients 102, and each client 102 may directly communicate with the other client via a peer-to-peer network. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and the like. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.

In an exemplary embodiment, as shown in fig. 2, a method for synchronizing a configuration file is provided, which may be performed by a target client, that is, any client 102 of a plurality of clients, including the following steps 201 to 203. Wherein:

s201, responding to a configuration file downloading notification sent by a server, and acquiring a seed file of the configuration file from the server.

In the embodiment of the application, the seed file is a shared file of a peer-to-peer network formed by the server and a plurality of clients.

The peer-to-peer network is essentially different from the client/server architecture that is currently dominant in the network, i.e., there is no central node (or central server) in the overall network architecture; participants (nodes) in the network share a portion of the owned resources that can be directly accessed by other peer nodes in the network without going through an intermediate entity. Based on the characteristic of the peer-to-peer network, the peer-to-peer network formed in the application can realize direct transmission of the configuration file between the client and the client, and can realize that the target client obtains the configuration file from other clients.

In practical applications, when a peer-to-peer network technology is used to download a file, it is necessary to know which nodes in the peer-to-peer network include the file, and then the seed file is used. Typically, the seed file includes two parts of content, tracking server address and file information, respectively; the tracking server is a server for realizing direct transmission of a file among a plurality of nodes, and the file information generally comprises a plurality of block files of the file, a block file verification code of each block file and the like.

For example, the server may send a profile download notification to each client after preparing the seed file of the profile; for each client, after receiving the configuration file downloading notification sent by the server, the client may acquire the seed file of the configuration file from the server, for example, may send a seed file acquisition request of the configuration file to the server, and after receiving the seed file acquisition request, the server may send the seed file of the configuration file to the client.

S202, acquiring a download list of the configuration file from the server according to the seed file.

In the embodiment of the present application, the download manifest includes download records of configuration files by other clients than the target client among the plurality of clients. Since the target client refers to any one of the clients, any one of the clients may be another client of another client, it may be understood that the download record of the configuration file by the target client may also be included in the download manifest.

The tracking server is configured with a tracking function, i.e. how many nodes can be tracked and the same file is downloaded at the same time, can record information such as internet protocol (IP, internet Protocol) address and port of each node, and provides a node list for other nodes to acquire files from each node in the node list. The node here means each node in the peer-to-peer network, that is, the above-mentioned multiple clients, or may be any one server in the server.

For example, if the seed file includes the address of the tracking server, the target client may first obtain the address of the tracking server from the seed file, and then send a manifest obtaining request to the tracking server according to the address, so as to obtain the download manifest of the configuration file.

And S203, acquiring configuration files from other clients according to the download list.

Optionally, the download list further includes location information of other clients that have downloaded the configuration file, such as IP address and port information.

In addition, the server and the clients form a peer-to-peer network, and resources can be shared among all participants in the peer-to-peer network, namely, configuration files can be directly transmitted between the clients in the application, and further, the target client can directly acquire the configuration files from other clients.

Based on this, the target client may first obtain the location information of each other client according to the download manifest, and then send a configuration file obtaining request to each other client according to each location information, so as to obtain the configuration file from the other clients.

According to the configuration file synchronization method, the seed file of the configuration file is acquired from the server side by responding to the configuration file downloading notification sent by the server side, the seed file is a shared file of a peer-to-peer network formed by the server side and the plurality of clients, further, a downloading list of the configuration file is acquired from the server side according to the seed file, the downloading list comprises downloading records of the configuration file by other clients except the target client side in the plurality of clients, and finally, the configuration file is acquired from the other clients according to the downloading list. According to the method, the server and the clients form the peer-to-peer network, so that each client can directly communicate with each other, and each client can acquire the configuration file from other clients according to the seed file issued by the server through the peer-to-peer network technology, namely, each client does not need to acquire the configuration file from the server, but acquires the configuration file from other clients, and the pressure of synchronizing the configuration file by the server is relieved.

And downloading configuration files among all clients by adopting a peer-to-peer network technology, wherein the downloading of the configuration files is required to be carried out through an agent on the client. In some scenarios, when the client downloads the configuration file directly from other clients, it does not have a downloading tool that can download the configuration file, and in this case, a downloading agent needs to be installed in the client to implement the downloading function of the client. Based on this, in one exemplary embodiment, an alternative way of installing a download agent is provided. As shown in fig. 3, steps 301 to 303 may be included before the seed file of the configuration file is obtained from the server side. Wherein:

s301, feeding back a download agent without a configuration file to an application server.

In this embodiment of the present application, the server includes an application server, and the application server may send a configuration file download notification to the client, and may further schedule a download agent of the configuration file of the client, and when the client needs, send the download agent of the configuration file to the client.

Before acquiring a seed file of a configuration file from a server, determining whether a download agent exists in a target client; if there is no download agent, the target client may feed back to the application server the download agent for which no configuration file exists.

S302, if the download agent of the configuration file issued by the application server is received, the download agent with the configuration file is fed back to the application server.

After receiving the download agent of the configuration file fed back by the target client, the application server downloads the download agent of the configuration file to the target client. It should be noted that, here, the download agent that the application server issues the configuration file to the target client may be directly copying the download agent of the configuration file to the target client.

If the target client receives the download agent of the configuration file issued by the application server, the download agent of the configuration file already existing needs to be fed back to the application server.

S303, according to the starting notice of the download agent issued by the application server, starting the download agent of the configuration file.

When the application server receives the download agent with the configuration file fed back by the target client, the application server sends a start notification of the download agent to the target client so that the target client starts the download agent with the configuration file to perform the download operation of the configuration file. And the client starts the download agent of the configuration file according to the start notice of the download agent issued by the application server so as to perform the subsequent download operation of the configuration file.

It should be noted that, the download agent is a program allowed only in the process of updating the configuration file, and the configuration file will exit from the memory of the client after updating, so that the download agent is green software for the client, and will not affect the system performance of the client.

In this embodiment of the present application, since there is no download tool capable of downloading the configuration file in the client, the application server downloads the download agent of the configuration file to the client, so that the client may perform the downloading operation of the configuration file by starting the download agent.

When the server synchronizes the configuration file to each client, the configuration files in all the clients are updated, and there may be some cases that the configuration files in some clients do not need to be updated, i.e., the configuration files in some clients are already the latest configuration files and do not need to be updated; at this time, a lot of network bandwidth needs to be consumed, and the pressure of the server is too high, so that the problem needs to be solved by considering the method of the capacity expansion server, if the capacity expansion is not performed, the synchronous configuration file is delayed, and the effect of quick response of the system cannot be realized. Based on this, the present application considers that before the client obtains the seed file of the configuration file, whether the local configuration file has a difference from the configuration file on the server is verified through an Entity Tag (ETag) protocol, and if the difference does not exist, the client does not need to update the configuration file any more. As shown in fig. 4, in one embodiment, before the seed file of the configuration file is obtained from the server, steps 401 to 403 are further included. Wherein:

S401, sending a configuration file detection request to the file server according to the address information of the file server.

In this embodiment of the present application, the server further includes a file server, where a configuration file is stored in the file server.

The configuration file downloading notification comprises address information of the file server, the target client can acquire the address information of the file server after receiving the configuration file downloading notification, and then a configuration file detection request is sent to the file server through an ETag protocol according to the address information of the file server so as to verify whether the difference exists between the local configuration file and the configuration file on the server.

S402, receiving configuration file information fed back by a file server.

In the embodiment of the present application, the configuration file information may be information such as a file identifier or a file verification code.

After receiving the configuration file detection request sent by the target client, the file server sends configuration file information to the target client, and the target client can receive the configuration file information fed back by the file server.

S403, in the case that a difference exists between the configuration file information and the pre-stored local configuration file, executing the step of acquiring the seed file of the configuration file.

After receiving the configuration file information fed back by the file server, the target client can compare the configuration file information with the pre-stored file information of the local configuration file to determine whether the local configuration file is different from the configuration file on the file server; executing the step of acquiring the seed file of the configuration file under the condition that the difference exists between the configuration file information and the pre-stored local configuration file; if there is no difference between the configuration file information and the pre-stored local configuration file, the configuration file does not need to be updated.

In the embodiment of the application, whether the local configuration file is different from the configuration file on the server is verified through the ETag protocol, and if the local configuration file is not different from the configuration file on the server, the client does not need to update the configuration file, so that the transmission data volume of the network is reduced, and the network bandwidth pressure of the server is reduced.

The seed file is also stored in the file server, and when the client acquires the seed file of the configuration file from the server, a request needs to be sent to the file server to acquire the seed file of the configuration file. Based on this, in one embodiment, an alternative way of obtaining a seed file for a configuration file is provided. As shown in fig. 5, a seed file of a configuration file is obtained from a server, which includes steps 501 to 502. Wherein:
