Detailed Description
In order to solve the following problems in the prior art: the present invention provides a method, an apparatus, a storage medium, and a computer device for acquiring and providing a target resource, which are provided by the present invention, and further detailed descriptions will be provided below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
A first embodiment of the present invention provides a target resource obtaining method, which is applied to a terminal used by a user, and a flowchart of the method is shown in fig. 1, and specifically includes steps S101 to S104:
s101, sending a target resource acquisition request to an equipment load node;
s102, receiving node information of a device cache node determined by a device load node according to a target resource acquisition request;
s103, sending a target resource acquisition request to the equipment cache node according to the node information;
and S104, the receiving equipment cache node acquires the target resource sent by the request according to the target resource.
In this embodiment, when a user wishes to obtain a target resource, the user does not need to send a target resource obtaining request to a central load node of the CDN network, and only needs to send a target resource obtaining request to a device load node closest to a terminal held by the user; the equipment load node determines which equipment cache node the corresponding target resource is cached in according to the received target resource acquisition request, and feeds back node information of the equipment cache node to a user, wherein the node information mainly comprises an IP address or an MAC address and the like of the equipment cache node; after receiving the node information of the device cache node cached with the target resource, the user terminal sends a target resource acquisition request to the device cache node, and receives the target resource content sent by the device cache node according to the target resource acquisition request.
Specifically, all the device cache nodes and the device load nodes in this embodiment are intelligent audio-visual devices connected to the CDN network and having contents of playing and storing online video and audio, such as a mobile phone, an intelligent television, a network sound box, and the like. After comprehensively considering the network connection rate of each equipment node, the size of the storage space of the equipment, the marking and fragmentation strategy of the storage resource, the access frequency, the time distribution, the regional distribution, the resource failure and other factors, the CDN central load node formulates a corresponding service execution algorithm and provides a corresponding execution strategy for the equipment nodes. In order to avoid affecting the normal use of the intelligent audio-visual equipment by a user, the intelligent audio-visual equipment in the network space provides load or cache service for the network space according to the execution strategy provided by the CDN central load node only in a software upgrading mode when the intelligent audio-visual equipment is in a standby state.
Because the storage space of the intelligent audio-visual equipment is limited, the equipment load node cannot know the cache positions of all target resources, and the equipment cache node cannot cache all the target resources, so that if the node information of the equipment cache node corresponding to the target resource which the user wishes to acquire is not stored in the equipment load node closest to the user, the equipment load node cannot send the node information to the user terminal, and in order to ensure the timeliness of the user acquiring the target resource, the user terminal can detect whether the node information fed back by the equipment load node is received or not after sending the target resource request; if node information fed back by the equipment load node is received, a target resource request is sent to the corresponding equipment cache node according to the node information; and if the node information fed back by the equipment load node is not received, sending a target resource acquisition request to a central load node of the CDN. Further, when detecting whether node information fed back by the equipment load node is received, a preset time period may be set, and in the preset time period, if the node information fed back by the equipment load node is not received, the user terminal may consider that information of the target resource is not stored in the current equipment load node, that is, a request is sent to the central load node, and the preset time period may be set according to a network condition and a user requirement, which is not limited in this embodiment.
After sending a target resource acquisition request to a central load node of the CDN network, the user terminal receives server information of a central cache server sent by the central load node, sends the target resource acquisition request to a corresponding central cache server according to the server information, and finally receives a corresponding target resource sent by the corresponding central cache server. In actual use, the terminal can resend the target resource acquisition request to the equipment load node which is the second closest to the terminal if the terminal does not receive the reply after sending the target resource acquisition request to the equipment load node which is the closest to the terminal; if the fed-back node information has not been received yet, the target resource acquisition request may be sent to the device load node that is the third closest to the user terminal, or may be sent to the central load node, and it should be understood that steps of the method for the user terminal to acquire the target resource from the device load node that is the second closest to the user terminal or the device load node that is the third closest to the user terminal are also S101 to S104, and therefore details are not repeated again.
In this embodiment, the intelligent audio-visual device is modified into a device load node or a device cache node in the CDN network, so that a user does not need to request a resource from the central load node when desiring to obtain a target resource, but only needs to request the device load node closest to the central load node. The CDN service capability is improved under the condition of utilizing the existing equipment, the cost is relatively low, and meanwhile, the reliability of the CDN network with wide distribution area and increased node quantity scale in the case of dealing with the problems of network and equipment faults is also improved.
A second embodiment of the present invention provides a target resource providing method, which is applied to a device load node in a CDN network, and a flowchart thereof is shown in fig. 2, and specifically includes steps S201 to S203:
s201, receiving a target resource acquisition request sent by a terminal;
s202, determining node information of a device cache node where the target resource is located according to the target resource acquisition request;
and S203, transmitting the node information to the terminal.
All the device cache nodes and the device load nodes in this embodiment are intelligent audio-visual devices connected to the CDN network, such as a mobile phone, an intelligent television, and a network sound box, and having contents of playing and storing online video and audio. After comprehensively considering the network connection rate of each equipment node, the size of the storage space of the equipment, the marking and fragmentation strategy of the storage resource, the access frequency, the time distribution, the regional distribution, the resource failure and other factors, the CDN central load node formulates a corresponding service execution algorithm and provides a corresponding execution strategy for the equipment nodes. In order to avoid affecting the normal use of the intelligent audio-visual equipment by a user, the intelligent audio-visual equipment in the network space provides load or cache service for the network space according to the execution strategy provided by the CDN central load node only in a software upgrading mode when the intelligent audio-visual equipment is in a standby state.
When a user terminal wants to acquire a target resource, a target resource acquisition request is sent to an equipment load node, after the equipment load node receives the target resource acquisition request, the node information of an equipment cache node where the target resource is located is determined according to the target resource acquisition request, the node information mainly comprises an IP address or an MAC address and the like of the equipment cache node, and after the node information of the equipment cache node is acquired, the node information is sent to the user terminal, so that the user can access the corresponding equipment cache node according to the node information to acquire the target resource.
Because the storage space of the intelligent audio-visual equipment is limited, the equipment load node cannot know the cache positions of all target resources, and the equipment cache node cannot cache all the target resources, therefore, after receiving the target resource acquisition request, the equipment load node firstly detects whether the description information of the target resource requested in the target resource acquisition request is stored in the information table of the equipment load node, such as the information of the equipment cache node where the target resource is stored, the size of the target resource, and the like; if the description information of the target resource is stored, the equipment load node determines the node information of the equipment cache node where the target resource is located according to the description information of the target resource and sends the node information to the user terminal; and when the description information of the target resource is not stored, the equipment load node sends the target resource acquisition request to the central load node for updating the resource.
When receiving a target resource acquisition request sent by an equipment load node, a central load node sends synchronization information to the equipment load node, wherein the synchronization information at least comprises description information of a target resource corresponding to the target resource acquisition request and server information of a central cache server storing the target resource; after receiving the synchronization information, the equipment load node instructs a preset equipment cache node to acquire the target resource from a corresponding central cache server according to the synchronization information and caches the target resource so as to complete the updating of the resource; and finally, storing the description information of the target resource and the node information of the cache node of the preset equipment. Preferably, when the device load node selects a predetermined device cache node for caching the target resource, the device load node may determine the size of the target resource, the network condition of the device cache node, and the storage size.
In the embodiment, the intelligent audition device in the standby state in the network is used as a load or a cache node, and the distributed cache service is constructed by the video network data in the network space by using relatively idle network resources, storage resources and computing resources, so that the network distance between the service provider and the user is reduced, the service efficiency and the network resource utilization rate of the CDN are improved, the cost of network expansion is reduced, the risk resistance of the CDN is improved, and the problem of large-area service failure caused by regional network faults is prevented.
A third embodiment of the present invention provides a target resource obtaining apparatus, which is installed in a terminal used by a user, and a schematic structural diagram of the apparatus is shown in fig. 3, and the apparatus mainly includes: a first sending module 301, configured to send a target resource obtaining request to an equipment load node; a first receiving module 302, coupled to the first sending module 301, configured to receive node information of a device cache node determined by a device load node according to the target resource acquisition request; the first sending module 301 is further configured to send a target resource obtaining request to the device cache node according to the node information; the first receiving module 302 is further configured to receive a target resource sent by the device cache node according to the target resource obtaining request.
In this embodiment, the target resource obtaining apparatus is installed in a terminal used by a user, and when the user wishes to obtain a target resource, the first sending module 301 does not need to send a target resource obtaining request to a central load node of the CDN network, but only needs to send the target resource obtaining request to an equipment load node closest to the terminal held by the user; the equipment load node determines which equipment cache node the corresponding target resource is cached in according to the received target resource acquisition request, and feeds back node information of the equipment cache node to a user, wherein the node information mainly comprises an IP address or an MAC address and the like of the equipment cache node; after the first receiving module 302 receives the node information of the device cache node where the target resource is cached, the first sending module 301 sends a target resource obtaining request to the device cache node, and receives the target resource content sent by the device cache node according to the target resource obtaining request through the first receiving module 302.
Specifically, all the device cache nodes and the device load nodes in this embodiment are intelligent audio-visual devices connected to the CDN network and having contents of playing and storing online video and audio, such as a mobile phone, an intelligent television, a network sound box, and the like. After comprehensively considering the network connection rate of each equipment node, the size of the storage space of the equipment, the marking and fragmentation strategy of the storage resource, the access frequency, the time distribution, the regional distribution, the resource failure and other factors, the CDN central load node formulates a corresponding service execution algorithm and provides a corresponding execution strategy for the equipment nodes. In order to avoid affecting the normal use of the intelligent audio-visual equipment by a user, the intelligent audio-visual equipment in the network space provides load or cache service for the network space according to the execution strategy provided by the CDN central load node only in a software upgrading mode when the intelligent audio-visual equipment is in a standby state.
Because the storage space of the intelligent audio-visual device is limited, the device load node cannot know the cache positions of all the target resources, and the device cache node cannot cache all the target resources, therefore, if the node information of the device cache node corresponding to the target resource that the user wishes to acquire is not stored in the device load node closest to the user, the device load node does not send the node information to the user terminal, in order to ensure the timeliness of the user acquiring the target resource, the structural schematic diagram of the target resource acquiring device may also be as shown in fig. 4, the target resource acquiring device may further include a first detecting module 303, and the first detecting module 303 may detect whether the node information fed back by the device load node is received after the first sending module 301 sends the target resource request; if node information fed back by the equipment load node is received, a target resource request is sent to the corresponding equipment cache node according to the node information; if the node information fed back by the device load node is not received, the first sending module 301 sends a target resource obtaining request to a central load node of the CDN network. Further, when detecting whether the node information fed back by the equipment load node is received, the first detecting module 303 may set a preset time length, and in the preset time length, if the node information fed back by the equipment load node is not received, the user terminal may consider that the information of the target resource is not stored in the current equipment load node, that is, send a request to the central load node, where the preset time length may be set according to a network condition and a user requirement, and is not limited in this embodiment.
After the first sending module 301 sends the target resource obtaining request to the central load node of the CDN network, the first receiving module 302 receives server information of the central cache server sent by the central load node, the first sending module 301 sends the target resource obtaining request to the corresponding central cache server according to the server information, and finally, the first receiving module 302 receives the corresponding target resource sent by the corresponding central cache server. In actual use, the terminal can resend the target resource acquisition request to the equipment load node which is the second closest to the terminal if the terminal does not receive the reply after sending the target resource acquisition request to the equipment load node which is the closest to the terminal; if the fed-back node information has not been received, the target resource acquisition request may be sent to the device load node that is third closest to the user terminal, or may be sent to the central load node.
In this embodiment, the intelligent audio-visual device is modified into a device load node or a device cache node in the CDN network, so that a user does not need to request a resource from the central load node when desiring to obtain a target resource, but only needs to request the device load node closest to the central load node. The CDN service capability is improved under the condition of utilizing the existing equipment, the cost is relatively low, and meanwhile, the reliability of the CDN network with wide distribution area and increased node quantity scale in the case of dealing with the problems of network and equipment faults is also improved.
A fourth embodiment of the present invention provides a target resource providing apparatus, which is installed in a device load node in a CDN network, and a schematic structural diagram of the apparatus is shown in fig. 5, where the apparatus mainly includes: a second receiving module 501, configured to receive a target resource obtaining request sent by a terminal; a determining module 502, coupled to the second receiving module, configured to determine node information of a device cache node where the target resource is located according to the target resource obtaining request; a second sending module 503, coupled to the determining module, for sending the node information to the terminal.
In this embodiment, all the device cache nodes and the device load nodes are intelligent audio-visual devices connected to the CDN network and having contents of playing and storing online video and audio, such as a mobile phone, an intelligent television, a network sound box, and the target resource providing device is installed in all the device load nodes in the CDN network. After comprehensively considering the network connection rate of each equipment node, the size of the storage space of the equipment, the marking and fragmentation strategy of the storage resource, the access frequency, the time distribution, the regional distribution, the resource failure and other factors, the CDN central load node formulates a corresponding service execution algorithm and provides a corresponding execution strategy for the equipment nodes. In order to avoid affecting the normal use of the intelligent audio-visual equipment by a user, the intelligent audio-visual equipment in the network space provides load or cache service for the network space according to the execution strategy provided by the CDN central load node only in a software upgrading mode when the intelligent audio-visual equipment is in a standby state.
When a user terminal wants to acquire a target resource, a target resource acquisition request is sent to an equipment load node, after a second receiving module 501 in the equipment load node receives the target resource acquisition request, a determining module 502 determines node information of an equipment cache node where the target resource is located according to the target resource acquisition request, wherein the node information mainly comprises an IP (Internet protocol) address or an MAC (media access control) address and the like of the equipment cache node, and after the node information of the equipment cache node is acquired, the node information is sent to the user terminal by a second sending module 503, so that the user can access the corresponding equipment cache node according to the node information to acquire the target resource.
Since the storage space of the intelligent audio-visual device is limited, the device load node cannot know the cache positions of all the target resources, and the device cache node cannot cache all the target resources, the structural schematic diagram of the target resource providing apparatus may also be as shown in fig. 6, after receiving the target resource acquisition request, the device load node first detects, by the second detection module 504, whether the description information of the target resource requested in the target resource acquisition request is stored in its own information table, such as the size of the target resource stored in the device cache node; if the description information of the target resource is stored, the determining module 502 determines the node information of the device cache node where the target resource is located according to the description information of the target resource, and sends the node information to the user terminal; when the description information of the target resource is not saved, in order to update the resource, the second sending module 503 sends the target resource obtaining request to the central load node.
When receiving a target resource acquisition request sent by an equipment load node, a central load node sends synchronization information to the equipment load node, wherein the synchronization information at least comprises description information of a target resource corresponding to the target resource acquisition request and server information of a central cache server storing the target resource; after receiving the synchronization information, the second receiving module 501 instructs, through the instructing module 505, the predetermined device cache node to obtain the target resource from the corresponding central cache server according to the synchronization information and cache the target resource, so as to complete the update of the resource; finally, the storage module 506 stores the description information of the target resource and the node information of the cache node of the predetermined device. Preferably, when the device load node selects a predetermined device cache node for caching the target resource, the device load node may determine the size of the target resource, the network condition of the device cache node, and the storage size.
In the embodiment, the intelligent audition device in the standby state in the network is used as a load or a cache node, and the distributed cache service is constructed by the video network data in the network space by using relatively idle network resources, storage resources and computing resources, so that the network distance between the service provider and the user is reduced, the service efficiency and the network resource utilization rate of the CDN are improved, the cost of network expansion is reduced, the risk resistance of the CDN is improved, and the problem of large-area service failure caused by regional network faults is prevented.
