Detailed Description
In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.
The CDN is an intelligent virtual network constructed on the basis of the existing network, and by means of the edge servers deployed in various places, a user can obtain required content nearby through load balancing, content distribution, scheduling and other functional modules of the center platform, network congestion is reduced, and user access response speed and hit rate are improved.
In recent years, with the rapid popularization of intelligent terminals, the mobile internet has become a main way for people to acquire information. More and more users search information through a search engine, and the loading speed of the information is particularly important in user experience. As a way, the content delivery network can be adopted to cache the resource in the CDN edge node accessed by the user network, when the user needs to access the resource, the resource can be obtained from the nearby CDN edge node, and the resource does not need to be obtained from the server side, so that the waiting time of the user is reduced, and the loading speed of the information can be increased. However, the inventor finds that, for the first accessed resource, the CDN edge node needs to perform the back-source processing, and in some weak network environments, the CDN edge node has the problems of long time (1-10 seconds) and unreliable quality (the back-source processing is easy to fail) due to network reasons during the back-source processing, which may cause the long time of the back-source processing, further affect the resource loading speed, and reduce the user experience.
In order to solve the problems, the inventor discovers through long-term research that a broadcast message sent by a service server can be received by a client, wherein the broadcast message is sent when the service server detects that resources are uploaded for the first time, the broadcast message carries an identifier of the resources, and then a resource preloading request carrying the identifier of the resources is sent to a corresponding content distribution node, so that the content distribution node preloads the resources to the local. Therefore, under the condition that the client receives the broadcast message sent by the service server when the first uploading of the resource is detected, the resource preloading request carrying the identification of the resource is sent to the corresponding content distribution node, so that the content distribution node can preload the resource to the local, the preheating loading of the content distribution node to the resource is realized, the time for the content distribution node to request the resource from the source station back to the source station is reduced through the preheating loading, the first loading speed of the resource is accelerated, and the user experience is improved.
For the purpose of facilitating a detailed description of the present application, an application environment in the embodiments of the present application will be described with reference to the accompanying drawings.
Referring to fig. 1, an application environment of a resource loading method provided in an embodiment of the present application is shown in fig. 1, where the application environment may be understood as a network system 10 provided in an embodiment of the present application, and the network system 10 includes: client 12, client 13, CDN source server 14, and CDN cache server 15.
The CDN source server 14 and the CDN cache server 15 may be one server (network access server), a server cluster (cloud server) formed by a plurality of servers, or a cloud computing center (database server). The client 12 and the client 13 may be any devices with communication and storage functions, including but not limited to PCs (Personal Computer, personal computers), PDAs (tablet computers), smart televisions, smart phones, smart wearable devices, or other intelligent communication devices with network connection functions.
Alternatively, the client 12 and the client 13 may be clients of an instant messaging application, a social network application, or an internet access application, and the clients may be application clients (such as a video playing application in a mobile APP) or web clients (such as a browser, a web live platform, etc.), which are not limited herein.
Alternatively, the CDN source server 14 may establish a communication connection with the client 12 and a different client 13 over a network, which may be a wireless network as one way.
In one embodiment, the user may upload the resource to the CDN source server 14 through the client 12, and the CDN source server 14 may send the resource to each CDN cache server 15 for caching, so that the client 13 may directly request the resource from the CDN cache server 15. Alternatively, if the resource is the first uploaded resource, when the client 13 requests the resource from the CDN cache server 15, the CDN cache server 15 needs to request the source from the CDN source server 14, in which manner the client 12 and the client 13 may be the same client (i.e., in which manner the client 12 may be identical to the client 13).
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a flowchart of a resource loading method according to an embodiment of the present application is shown, where the embodiment provides a resource loading method, which may be applied to an electronic device, and the method includes:
step S110: the client receives the broadcast message sent by the service server.
Optionally, the broadcast message in this embodiment is sent by the service server when detecting that there is a first upload of a resource, where the broadcast message carries an identifier of the first upload resource. The resource may be a picture, a file, a page, or the like, and the type of the resource and the content form are not limited in this embodiment. The identifier may be understood as a target resource locator (i.e. a CDN-URL, where the CDN is a CDN cache server corresponding to a client uploading resources, optionally, the CDN cache server in this embodiment may be understood as a content delivery node, optionally, a CDN cache node closest to the client and/or having an optimal network condition may be determined according to an IP address of the client as a corresponding content delivery node), and the target resource locator may characterize a storage path of resources associated with the client generated by the service server, where storage paths of resources associated with different clients may be different.
As one approach, the client may receive broadcast messages sent by the service server based on a long connection channel with the service server. For example, a TCP connection between the client and the service server may be pre-established, in which way the client may receive broadcast messages sent by the service server based on a TCP long connection path with the service server. The establishment principle and the establishment procedure of the TCP connection between the client and the service server may refer to the related art, and are not described herein.
Step S120: and sending a resource preloading request carrying the identification of the resource to a corresponding content distribution node so that the content distribution node preloads the resource to the local based on the identification of the resource.
As a way, after the identifier of the resource is obtained, the client may send a resource preloading request carrying the identifier to the corresponding content distribution node according to the identifier, so that the content distribution node may preload the resource to the local based on the identifier of the resource. The resource is the resource requested by the client for the first time, and the content distribution node can be prompted to load the resource in advance by sending the preloading request, so that the loading time in the resource loading process can be reduced, and the resource loading speed can be improved.
After the client sends the resource preloading request carrying the identifier to the corresponding content distribution node, the corresponding content distribution node may be instructed to send the resource preloading request to the source station server (which may be understood as the CDN source station server described above), so that the resource corresponding to the identifier of the resource returned by the source station server may be obtained, so that the corresponding content distribution node may preload the resource to the local, thereby reducing resource obtaining or waiting time consumption in a subsequent service request process, and further improving user experience.
Alternatively, the location of the client may vary, e.g., the client may move from location a to location B, and if the distance between location a and location B is relatively large, the content distribution node corresponding to the client may vary, i.e., the content distribution nodes corresponding to clients in different locations may be different. Alternatively, the specific distance between the position a and the position B in the present embodiment may not be limited.
Optionally, during the process of changing the location of the client, the network environment may also change, for example, if the location of the client moves from the ground to the ground, the network signal may be weakened, in this way, if the client sends a resource preloading request carrying the identifier of the resource to the corresponding content distribution node, the sending may fail. As a way to improve this problem, the client may first detect, after receiving the broadcast message sent by the service server, whether the network environment where the client is located meets a preset condition, and optionally, if the network environment where the client is located meets the preset condition, the client may continue to send a resource preloading request carrying the identifier of the resource to the corresponding content distribution node; optionally, if the network environment of the location of the client does not meet the preset condition, the client may delay sending a resource preloading request carrying the identifier of the resource to the corresponding content distribution node, where the specific duration of the delay may be adjusted according to the actual network environment condition. Alternatively, the preset condition may be that the network signal of the network environment is greater than a specified threshold, and the specific value of the specified threshold may not be limited.
Optionally, after the client sends the resource preloading request carrying the identifier of the resource to the corresponding content distribution node, whether a preloading request receiving success signal returned by the service server is received or not may be detected, optionally, if the preloading request receiving success signal returned by the service server is not received, the client may send the resource preloading request carrying the identifier of the resource to the corresponding content distribution node again, or continuously send the resource preloading request carrying the identifier of the resource to the corresponding content distribution node for a period of time, so as to ensure that the preloading request can be successfully sent.
According to the resource loading method provided by the embodiment, the broadcasting message sent by the service server is received through the client, wherein the broadcasting message is sent when the service server detects that the resource is uploaded for the first time, the broadcasting message carries the identification of the resource, and then a resource preloading request carrying the identification of the resource is sent to the corresponding content distribution node, so that the content distribution node preloads the resource to the local. According to the method, the device and the system, when receiving the broadcast message sent by the service server when the first uploading of the resource is detected, the client sends the resource preloading request carrying the identifier of the resource to the corresponding content distribution node, so that the content distribution node can preload the resource to the local, the preheating loading of the content distribution node on the resource is realized, the time for the content distribution node to request the resource from the source station back to the source station is reduced through the preheating loading, the first loading speed of the resource is accelerated, and the user experience is improved.
Referring to fig. 3, a flowchart of a resource loading method according to another embodiment of the present application is shown, where the embodiment provides a resource loading method, which may be applied to an electronic device, and the method includes:
step S210: the client receives the broadcast message sent by the service server.
Step S220: and receiving the position identification of the client sent by the service server.
It will be appreciated that, as the location of the client moves, the content delivery node corresponding to the client may change, for example, the content delivery node corresponding to the client is "CDN-1" at the location a, and the content delivery node corresponding to the client is "CDN-2" at the location B, and optionally, the content delivery node CDN-1 and the content delivery node CDN-2 are different content delivery nodes, in this way, if the client receives a broadcast message sent by the service server at the location a, the location of the client changes from the location a to the location B within a relatively short time (for example, 5 minutes, a specific duration may not be limited), and in this way, if the client still sends a resource preloading request to the content delivery node corresponding to the location a, it may cause a transmission failure or a transmission smooth or a transmission failure due to a network signal failure or the like. As a way to improve this problem, the client in this embodiment may receive the location identifier of the client sent by the service server, and optionally, the location identifier is an identifier corresponding to the current location of the client.
The client may receive the location data related to the client, which is periodically read by the service server, and further obtain the current location identifier of the client from the location data, and optionally, the specific implementation technology may refer to related technology, which is not described herein.
Step S230: and taking the content distribution node corresponding to the position identifier as the corresponding content distribution node.
As one way, after the location identifier of the client is acquired, the content distribution node corresponding to the location identifier may be used as the content distribution node corresponding to the client. Alternatively, different location identifiers may correspond to different content distribution nodes, so that the content distribution node corresponding to the client may be accurately acquired according to the acquired location identifier.
Step S240: and sending a resource preloading request carrying the identification of the resource to a corresponding content distribution node so that the content distribution node preloads the resource to the local based on the identification of the resource.
According to the resource loading method provided by the embodiment, the broadcasting message sent by the service server is received through the client, the position identification of the client sent by the service server is received, the content distribution node corresponding to the position identification is used as the content distribution node corresponding to the client, and then a resource preloading request carrying the identification of the resource is sent to the corresponding content distribution node, so that the content distribution node preloads the resource to the local. The accurate sending of the resource preloading request is realized, so that the accuracy and the reliability of resource loading are improved. The preheating loading of the resources by the content distribution node reduces the time for the content distribution node to request the resources from the source station, accelerates the first loading speed of the resources and improves the user experience.
Referring to fig. 4, a flowchart of a resource loading method according to another embodiment of the present application is shown, where the method may be applied to an electronic device, and includes:
step S310: the service server obtains a resource locator of the resource sent by the client.
In this embodiment, the service server may be understood as a server corresponding to the browser, and the user may access resources to the service server through the client.
Among other things, a resource locator may be understood as a uniform resource locator (Uniform Resource Locator, URL for short). As a way, after the client uploads the resource to the CDN source server for the first time, the URL returned by the CDN source server may be obtained, and optionally, the service server may receive the URL uploaded by the client, so that when an access request of the resource is received, the service server may return an identifier pointed by the access request to the corresponding client.
Step S320: an identification corresponding to the resource is generated based on the resource locator.
Optionally, after acquiring the resource locator of the resource, the service server may generate an identifier corresponding to the resource based on the resource locator, for example, the service server may replace the URL uploaded by the client with a CDN-URL, and optionally, the CDN may be understood as a CDN cache server corresponding to the client uploading the resource.
Step S330: and if the resource is detected to be uploaded for the first time, sending a broadcast message of the first uploading of the resource to a target client.
Optionally, after the service server generates the identifier corresponding to the resource, the resource and the identifier corresponding to the resource may be stored in a mapping relationship, and optionally, if the same identifier as the identifier is detected to exist in the storage process, the resource and the same identifier may be directly stored correspondingly. If the same identifier as the identifier is not detected, the resource can be judged to be uploaded for the first time, in this way, the service server can store the resource and the identifier corresponding to the resource in an associated mode, and meanwhile, send a message for uploading the resource for the first time to the target client, so that the target client can send a resource preloading request carrying the identifier of the resource to the corresponding content distribution node based on the broadcast message, and further, the content distribution node can preload the resource to the local based on the identifier of the resource.
Wherein, the broadcast message carries the identification of the resource. It should be noted that the number of the target clients may be plural, and the specific number may not be limited. In some implementations, the target client and the client uploading the resource may be the same client. For example, if the target client and the client uploading the resource are the same client, the client can request to acquire the resource when the resource needs to be used by uploading the resource to the source station server without being stored locally, so that the memory required by the resource is reduced, and the running efficiency of the device is improved. Alternatively, in other embodiments, the target client and the client uploading the resource may not be the same client, in which way, when detecting that the resource is first uploaded, the service server may send a broadcast message of the first uploading of the resource to at least one other client.
Alternatively, the service server may determine the target client from a plurality of clients in a variety of ways. For example, as one way, the service server may select an active client from a preset number of clients, and further use the active client as a target client. The specific number of the preset number may not be limited, and the active client may be understood as a client with a higher access frequency (for example, the access frequency is greater than 5 times/hour/day, optionally, the specific number and format of the access frequency may be set according to the actual situation), or may be understood as a client with an online time period exceeding a preset time period (for example, a client with an online time period exceeding 3 hours in one day).
Alternatively, as another way, the service server may obtain account levels of a preset number of clients, rank the account levels of the clients, and in this way, may select the client with the top rank as the target client. For example, assume that among 1000 clients, there are level 1, level 2, level 3, level 4, level 5, and level 6, and that level 1< level 2< level 3< level 4< level 5< level 6, where the number of clients corresponding to level 6 is 5, the number of clients corresponding to level 5 is 17, the number of clients corresponding to level 4 is 39, the number of clients corresponding to level 3 is 300, the number of clients corresponding to level 2 is 420, the number of clients corresponding to level 1 is 219, and if the clients corresponding to level 4, level 5, and level 6 are selected as target clients, the number of target clients is 61.
According to the resource loading method provided by the embodiment, the service server is used for acquiring the resource locator of the resource sent by the client, then the identifier corresponding to the resource is generated based on the resource locator, and then if the resource is detected to be uploaded for the first time, the broadcast message of the first time uploading of the resource is sent to the target client, so that the target client can send a resource preloading request carrying the identifier of the resource to the corresponding content distribution node based on the broadcast message, and further the content distribution node can locally preload the resource based on the identifier of the resource, thereby reducing the time length of the resource requesting from the source station by the content distribution node, accelerating the first loading speed of the resource, and further improving the user experience.
Referring to fig. 5, a flowchart of a resource loading method according to another embodiment of the present application is shown, where the method may be applied to an electronic device, and includes:
step S410: the service server obtains a resource locator of the resource sent by the client.
Step S420: an identification corresponding to the resource is generated based on the resource locator.
Step S430: and if the resource is detected to be uploaded for the first time, sending a broadcast message of the first uploading of the resource to a target client.
Wherein, the broadcast message carries the identification of the resource. Optionally, when the service server sends a broadcast message for first uploading of the resource to the target client, the target client may be a client for first uploading of the resource to the source station server, or may be another client. Alternatively, as shown in fig. 5, if the target client is a client that uploads the resource to the source station server for the first time, the service server may send a broadcast message of the first upload of the resource to the client 12 (as shown by a dashed arrow in fig. 5), and it may be understood that in this case, the number of target clients may be multiple, that is, the service server may also send broadcast messages of the first upload of the resource to other target clients at the same time.
Step S440: and the client receives the broadcast message sent by the service server.
Step S450: and sending a resource preloading request carrying the identification of the resource to a corresponding content distribution node so that the content distribution node preloads the resource to the local based on the identification of the resource.
Referring to fig. 6 and 7, the following describes an exemplary embodiment with a specific example:
in a specific application scenario, assuming that a resource is a picture, as shown in fig. 6, a timing flow chart of a client requesting access to the picture from a content distribution node in the prior art provided in the embodiment of the present application is shown. As shown in fig. 6, the client 12 may upload the picture locally to the CDN source server 14, the CDN source server 14 may return a source URL to the client 12, the client 12 may send the source URL to the service server 11, and optionally the service server 11 may replace the source URL with a CDN-URL.
In one embodiment, the client 13 may initiate a service request to the service server 11, and the service server 11 may return the service data of the CDN-URL with the picture to the client 13 in response to the service request, in which manner, the client 13 (optionally, the client 13 and the client 12 may be the same client or not the same client) may request the picture from the content distribution node 15 according to the CDN-URL. Alternatively, if the request is the first request, since the picture is stored in the CDN source server 14 and the content delivery node 15 does not cache the picture, as a way, the content delivery node 15 may send a picture source return request to the CDN source server 14, and may further receive the picture returned by the CDN source server 14. Optionally, after receiving the picture returned by the CDN source server 14, the content delivery node 15 may cache the picture and return the picture to the client 13. It is to be understood that, in the process from the initiation of the picture request by the client 13 to the receipt of the picture, since the content delivery node needs to request the CDN source server for the picture to return to the source, it may take more time due to poor network, etc., so as to slow down the picture loading speed and affect the user experience.
As a way to improve the above-described problem, as shown in fig. 7, a long connection channel between the client 13 and the service server 11 may be established in advance, and alternatively, the long connection channel may be a TCP long connection channel. Optionally, through the long connection channel, after the service server 11 receives the source URL sent by the client 12, when the source URL is converted into a CDN-URL and stored, if the resource is found to be the first uploading instant and fast, a broadcast message of the first uploading of the resource is sent to the target client (for example, the target client may be the client 13 shown in fig. 7 at this time), so that unicast (which may be understood as unidirectional broadcast herein) to other target clients is realized, and a new picture needs to be preheated.
