Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
In an optional embodiment of the present application, an asset processing method is disclosed, which may be applied to, but not limited to, a terminal device such as a smart phone, a Personal digital assistant, a tablet Computer, a PC (Personal Computer), and the like, and preferably, may be applied to a portable mobile terminal device such as a smart phone, a Personal digital assistant, a tablet Computer, and the like.
Referring to the flow chart diagram of the asset processing method shown in fig. 1, in this embodiment, the asset processing method includes:
The first network may be, but is not limited to, an IPFS network configured by a plurality of terminal devices when the IPFS is applied to the terminal devices such as a smart phone, a personal digital assistant, a tablet computer, and a PC, and the IPFS network constitutes a content distribution system.
Each terminal device joining the first network, i.e. one content distribution node of the first network, can perform various applications such as data transmission, resource downloading, content sharing and the like with other nodes in the first network, and can hit and download required data from other nodes in the first network, and can also serve as a content data source for other nodes in the first network to hit and download required data.
In the embodiment of the present application, a content distribution node implemented by a terminal device in a first network is defined as a common node, which may be, but is not limited to, an IPFS node.
As a typical application scenario, a user of a terminal device often needs to download or install a required APP (application program) from an APP store of the device, and based on the solution of the present application, APP data resources of the APP store can be shared among different terminal devices joining a first network.
When a terminal device needs to obtain target data (it is easy to understand that the local end of the terminal device does not have the target data), the target data is preferentially obtained from a first network formed by a plurality of terminal devices, for example, when a user needs to download a target application program which is not provided by the local end of the device from an application store, the data file of the target application program is preferentially obtained from a common node formed by other terminal devices which join the first network. That is, the terminal device is also used as a content distribution node of the network, and preferentially acquires the target data from the common node formed by the terminal device, which obviously can implement traffic distribution to the storage server, avoids the defects of low data acquisition efficiency, low speed and the like existing in the traditional centralized data acquisition from the storage server, and can improve the acquisition efficiency and speed of data resources.
Specifically, this step determines at least one first node satisfying the data condition from the first network, and obtains the required target data from the at least one first node satisfying the data condition.
The first node satisfying the data condition may be a node in the first network that is in an active state and has at least part of the target data.
As a possible implementation, the whole/complete data file of the target data may be obtained from one first node satisfying the data condition; as another possible implementation, partial data files of the target data may be obtained from a plurality of first nodes that satisfy the data condition, and all/complete data files of the target data may be obtained by splicing/integrating the obtained partial data files.
Specifically, if one or more first nodes having all/complete data files of the target data exist in the first network, all/complete data files of the target data may be directly obtained from any one of the one or more first nodes, and if the first network has a plurality of first nodes each including a partial data file of the target data, corresponding partial data files of the target data may be respectively obtained from the plurality of first nodes, and the corresponding partial data files obtained from the respective first nodes may be spliced/integrated to obtain all/complete data files of the target data.
When the IPFS is applied to terminal equipment such as a smart phone, a tablet computer and a PC (personal computer) to form an IPFS network based on the terminal equipment, and resource downloading, content sharing and other applications are realized among the terminal equipment, the terminal equipment may quit the IPFS network due to deactivation or equipment failure, shutdown and other reasons, which will correspondingly cause data assets on the terminal equipment to quit the network, so that the service stability of the IPFS applied to the terminal equipment cannot be ensured, and the real-time online availability of data files cannot be ensured.
In order to overcome the defect, the present application further constructs a second network connected to the first network and composed of a plurality of storage servers, where each storage server in the second network is used as a node of the network, and corresponds to defining a node in the first network and composed of terminal devices as a common node.
When the first network does not have a first node satisfying the data condition due to a corresponding reason (for example, the terminal device with the target data exits from the first network and is no longer used as an effective node of the first network due to deactivation or device failure, shutdown, or the like), and accordingly the target data required cannot be hit from the first network, the target data required can be further hit and obtained from the super node of the second network.
For example, when a user needs to download a target application program that is not provided at the local end of the installation device from an application store, the data file of the target application program is preferentially hit and acquired from at least one first node (corresponding to at least one terminal device joining the first network) of the first network that meets the data condition, and if the first node that meets the data condition does not exist in the first network and the hit fails, the data file of the target application program is hit and acquired from a super node of the second network.
It should be noted that the super node in the second network is a storage server, which generally stores sufficient and comprehensive data resources and is generally online in real time, so that the service stability when the IPFS is applied to the terminal device can be ensured and the real-time online availability of the data source file can be ensured by combining the first network and the second network.
According to the above scheme, the resource processing method of the embodiment constructs a two-layer network architecture including a first network and a second network, where the first network includes a plurality of common nodes formed by terminal devices, and the second network includes a plurality of super nodes formed by storage servers; on the basis, the terminal equipment preferentially obtains the target data from the first network, and if the target data is not obtained, the terminal equipment obtains the required data from the second network. Therefore, the terminal equipment is used as the content distribution node, the required data is preferentially acquired from the common node formed by the terminal equipment, the traffic distribution of the storage server can be realized, the efficiency and the speed of network resource distribution can be effectively improved, and based on the double-layer network architecture, when a certain terminal equipment exits from the first network and cannot acquire the data on the terminal equipment, the required data can be further acquired from the super node of the second network, so that the stability of service and the real-time online availability of data files are ensured.
In an alternative embodiment of the present application, referring to fig. 2, when step 101 is executed to join the terminal device to the first network as a normal node in the first network, the asset processing method may further include the following processing:
The second node information at least includes a unique ID (Identity) corresponding to the terminal device in the first network when the terminal device is used as a common node of the first network, and in addition, may also include but is not limited to a node name, a node address, a node number, and other information, where the unique ID corresponding to the terminal device is an identifier generated by the terminal device based on a rule when the terminal device first joins the first network, and the identifier is subsequently used as a unique identifier of the terminal device Identity each time the terminal device joins the first network. Of course, in the specific implementation, the method is not limited to this, and a unique ID may be generated each time the terminal device joins the first network.
Optionally, the second network includes a master super node and a plurality of slave super nodes, and the master super node and the plurality of slave super nodes may specifically form the second network through a consensus algorithm (raft); the target super node that meets the node condition may be a master super node in the second network.
The slave super node in the second network is responsible for storing the data file, and the master super node in the second network, besides being responsible for storing the data file, may also be used for, but not limited to, being responsible for at least part of the following processes:
1) acquiring the latest data file from a third-party system, adding the latest data file into a second network, and ensuring the file availability based on a raft algorithm;
2) recording and maintaining a mapping table between the data file and a storage address (an address corresponding to a corresponding storage position in a master super node or a slave super node) in the second network;
3) hit of target data (hit of data from the master super node itself or from a slave super node), transmission or relay;
4) recording and maintaining node information of each common node in the first network;
5) and pushing a common node information set (such as a common node information list) in the first network to a common node in the first network.
Therefore, after the terminal device joins the first network to become a common node of the first network and obtains corresponding second node information, the second node information is sent to the main super node of the second network to inform the main super node that a new common node is generated in the first network, and the main super node updates the second node information to a node information set (such as a node information list) maintained for the first network.
Optionally, after the terminal device sends the second node information to the master super node of the second network, the master super node feeds back, to the terminal device, at least one piece of first node information corresponding to at least one common node in the first network based on the second node information of the terminal device, for example, a list of all or part of node information of common nodes in the current first network may be fed back to the terminal device.
As another implementation manner, after sending the second node information to the master super node of the second network, the terminal device may further continue to send a node information acquisition request to the master super node, and the master super node responds to the request and feeds back, to the terminal device, at least one piece of first node information corresponding to at least one common node in the first network based on the second node information of the terminal device.
After the terminal device obtains the at least one piece of first node information, for example, after obtaining the whole or partial node information list, it can determine which common nodes exist in the first network based on the obtained node information, thereby facilitating applications such as in-network resource downloading and content sharing with corresponding common nodes in the first network.
And step 204, caching the at least one piece of first node information.
Then, the terminal device caches at least one piece of first node information fed back by the master super node of the second network, for example, caches the received node information list. It is easy to understand that the second node information of the terminal device can also be carried by the master super node of the second network and pushed to other common nodes in the first network in the node information list. In this way, each common node joining the first network maintains a node information set (such as a node information list, but may also be in a non-list form, such as a tree structure form, a topological graph structure form, and the like) corresponding to at least a part of the common nodes in the first network, and on this basis, applications such as content sharing, resource downloading, and the like can be performed between the common nodes in the first network based on the maintained node information list.
In an alternative embodiment of the present application, as shown in fig. 3, the asset processing method may be further implemented by the following processes:
The activation condition may be, but is not limited to, any one of the following conditions:
the first condition is as follows: detecting that the terminal equipment enters a specific application;
and a second condition: detecting the starting of the terminal equipment;
for the above condition one, typically, for example, if the terminal device is detected to enter the application store, it indicates that the activation condition is met, and the node is automatically started to join the terminal device in the first network as its normal node.
For the second condition, but not limited to, a boot code may be integrated in a ROM (Read-Only Memory) of the terminal device, and once the device is booted (for example, a mobile phone is booted, a computer is booted, and the like), it indicates that the activation condition is met, and the node is automatically booted based on the boot code integrated in the ROM, and the terminal device is added to the first network as a normal node thereof.
After joining the first network as a normal node of the first network, as described above, the terminal device maintains a node information set of the normal node based on at least one piece of first node information pushed by the master super node of the second network.
On this basis, if the terminal device needs to obtain the target data, each common node existing in the first network may be determined based on the information set, and a data obtaining request for obtaining the target data may be sent to all or part of the common nodes indicated by each piece of first node information in the information set.
For example, when a user needs to download and install an application from an application store, the application store may preferentially search and acquire application data files from a first network formed by a plurality of terminal devices, and may specifically send request information for acquiring target data to all or part of common nodes indicated by each piece of first node information in a set based on a maintained first node information set.
If at least one first node meeting the data condition exists in each ordinary node receiving the request, that is, if at least one first node including at least part of the target data exists in each ordinary node receiving the request, it indicates that a data source of the target data exists in the first network, so that the target data can be acquired from the at least one first node meeting the data condition.
The method may download all/complete data files of the target data from one first node based on the actual holding condition of the first node on the data resource in the first network, or download different partial data in the target data from a plurality of first nodes respectively, and splice/integrate the obtained partial data to finally obtain all/complete data files of the target data.
When content is shared among the common nodes in the first network, sources of the shared data content may include, but are not limited to, the following:
1) the terminal equipment actively downloads and caches/stores the data content from the network;
2) hot data content which is pushed and cached/stored in the terminal equipment by a network;
3) when the first network queries and synchronizes the file list newly added to the second network from the second network periodically or based on condition triggering, caching/storing the corresponding file content of the corresponding terminal device based on a set strategy (such as a mode of sharing and the like).
On the contrary, if the first node meeting the data condition does not exist in the first network, it indicates that the data source of the target data does not exist in the first network, and in this case, the data acquisition request for acquiring the target data is continuously sent to the main super node in the second network.
After the main super node obtains the request, the storage address of the target data indicated by the request is determined based on the corresponding relation between the pre-stored data and the address, and the target data required by the hit of the storage address is further determined based on the storage address.
Wherein the target data may be stored in the master super node or in the corresponding slave super node. If the target data is stored in the main super node, the terminal device may receive the target data fed back by the main super node.
If the target data is not stored in the master super node, that is, the target data is stored in the slave super node, the terminal device may receive the target data fed back from the slave super node, where the target data is stored.
Under some conditions, based on the network architecture design, the slave super node in the second network can only perform data interconnection in the network of the second network and cannot perform data interaction with the external network equipment, that is, the whole second network realizes interaction with other networks through the master super node, and under the conditions, the terminal equipment can receive the target data transmitted by the master super node by relaying the target data of the slave super node.
In the embodiment, a first network based on terminal equipment is constructed, the terminal equipment is used as a content distribution node in the network, and a second network connected with the first network is constructed at the same time, when the terminal equipment needs to acquire target data, required data is preferentially acquired from a common node formed by the terminal equipment in the first network, so that traffic distribution can be performed on a storage server, the efficiency and the speed of network resource distribution can be effectively improved, and based on the double-layer network architecture, when a certain terminal equipment exits from the first network and cannot acquire the data on the terminal equipment, the required data can be further acquired from a super node of the second network, the stability of service is ensured, and the real-time online availability of file data is ensured.
In an alternative embodiment of the present application, referring to fig. 4, the asset processing method may further include the following processes:
and 307, detecting node states of the common nodes indicated by the cached first node information.
The node states of the normal nodes in the first network include two types: an active state and an inactive state. When the terminal device meets the activation condition and joins the first network, the node state of the terminal device enters the activation state, and when the user deactivates (for example, the user performs deactivation operation in an application store or in an information setting application of the terminal device), or exits a specific application (for example, exits the application store), or the device is turned off, has a fault, and the like, the node state of the terminal device becomes the non-activation state.
Therefore, the information of the invalid node in the inactive state may exist in the first node information set maintained by each common node in the first network, which brings disadvantages to content sharing among the common nodes and cannot be located and routed to the valid node based on the invalid node information.
In order to ensure the validity of each piece of first node information in a first node information set maintained by each common node of the first network, so that each piece of first node information can indicate an active node in an active state, in this embodiment, the common node where the terminal device is located further detects a node state of the common node indicated by each piece of cached first node information.
Optionally, the common node where the terminal device is located periodically sends a heartbeat packet to each of other common nodes indicated by the maintained first node information set, if response information of the common node indicated by some first node information can be received within a set time period, it indicates that the common node indicated by the first node information is in an activated state, and is a valid node, and if response information of the common node indicated by the first node information is not received within the set time period, it indicates that the common node indicated by the first node information is in an inactivated state, and is an invalid node,
If the common node indicated by the certain first node information is in the activated state through detection, the first node information is kept cached in the terminal equipment.
On the contrary, if the common node indicated by the first node information is in an inactive state, the common node is removed from the information set of the first node information maintained by the terminal device, and the first node information is not cached any more.
In this embodiment, by detecting the node state of the common node indicated by each piece of cached first node information and updating the cache based on the detected node state, each piece of first node information cached on the terminal device serving as the common node of the first network can be made to be valid information and can indicate the corresponding common node in the activated state in the first network, so that effective node location and routing support can be provided for applications such as content sharing and resource downloading among the common nodes in the first network.
In addition, in an optional embodiment of the present application, the asset processing method is performed by an agent running on the terminal device.
Specifically, as shown in fig. 5, a proxy (Sidecar) is implemented in advance on each terminal device.
After the terminal device is added into the first network to be a common node of the first network, the proxy is utilized to package various node functions required when the terminal device is used as a native node of the first network.
For example, adding the terminal device a to the IPFS content distribution system to make it become the IPFS native node Peer a of the IPFS content distribution system, and encapsulating, in the proxy Sidecar of the terminal device a, various node functions that the IPFS native node Peer a needs to possess, where the encapsulated node functions may include but are not limited to: data discovery oriented to a first network and a second network, traffic management (throttling, downgrading, fusing), content sharing control inside the first network, information interaction control with the second network, and the like. As shown in fig. 6, the service grid is used to automatically discover and schedule resources in the first network and the second network through a network layer (network stack), so that the service stability of the content sharing service for the terminal device can be ensured, the hit rate of the user when downloading required data is increased, and the experience of the user when downloading resources is greatly improved.
In this embodiment, by constructing two layers of networks (a first network and a second network), the terminal device can also serve as a content distribution node, thereby improving the efficiency and speed of network resource distribution, and meanwhile, based on the second network formed by the storage server, the service stability when the IPFS is operated on the terminal device is ensured, and the real-time online availability of the data file can be ensured.
Corresponding to the asset processing method, the embodiment of the present application further discloses a terminal device, where the terminal device may be, but is not limited to, a smart phone, a personal digital assistant, a tablet computer, a PC, and the like, and preferably, the terminal device is a portable mobile terminal such as a smart phone, a personal digital assistant, a tablet computer, and the like.
Referring to the schematic structural diagram of the terminal device shown in fig. 7, the terminal device may include:
a memory 701 for storing at least one set of instructions;
a processor 702 configured to invoke and execute the set of instructions in the memory, the processor configured to:

obtaining target data by at least one first node satisfying a data condition in the first network;
and if the first network does not have a first node meeting the data condition, acquiring target data through a super node in a second network, wherein the second network comprises a plurality of super nodes, and the super node is a storage server.
The first network may be, but is not limited to, an IPFS network configured by a plurality of terminal devices when the IPFS is applied to the terminal devices such as a smart phone, a personal digital assistant, a tablet computer, and a PC, and the IPFS network constitutes a content distribution system.
Each terminal device joining the first network, i.e. one content distribution node of the first network, can perform various applications such as data transmission, resource downloading, content sharing and the like with other nodes in the first network, and can hit and download required data from other nodes in the first network, and can also serve as a content data source for other nodes in the first network to hit and download required data.
In the embodiment of the present application, a content distribution node implemented by a terminal device in a first network is defined as a common node, which may be, but is not limited to, an IPFS node.
As a typical application scenario, a user of a terminal device often needs to download or install a required APP (application program) from an APP store of the device, and based on the solution of the present application, APP data resources of the APP store can be shared among different terminal devices joining a first network.
When a terminal device needs to obtain target data (it is easy to understand that the local end of the terminal device does not have the target data), the target data is preferentially obtained from a first network formed by a plurality of terminal devices, for example, when a user needs to download a target application program which is not provided by the local end of the device from an application store, the data file of the target application program is preferentially obtained from a common node formed by other terminal devices which join the first network. That is, the terminal device is also used as a content distribution node of the network, and preferentially acquires the target data from the common node formed by the terminal device, which obviously can implement traffic distribution to the storage server, avoids the defects of low data acquisition efficiency, low speed and the like existing in the traditional centralized data acquisition from the storage server, and can improve the acquisition efficiency and speed of data resources.
And in particular, the processor 702 determines at least one first node from the first network that satisfies the data condition and obtains the desired target data from the at least one first node that satisfies the data condition.
The first node satisfying the data condition may be a node in the first network that is in an active state and has at least part of the target data.
As a possible implementation, the whole/complete data file of the target data may be obtained from one first node satisfying the data condition; as another possible implementation, partial data files of the target data may be obtained from a plurality of first nodes that satisfy the data condition, and all/complete data files of the target data may be obtained by splicing/integrating the obtained partial data files.
Specifically, if one or more first nodes having all/complete data files of the target data exist in the first network, all/complete data files of the target data may be directly obtained from any one of the one or more first nodes, and if the first network has a plurality of first nodes each including a partial data file of the target data, corresponding partial data files of the target data may be respectively obtained from the plurality of first nodes, and the corresponding partial data files obtained from the respective first nodes may be spliced/integrated to obtain all/complete data files of the target data.
When the IPFS is applied to terminal equipment such as a smart phone, a tablet computer and a PC (personal computer) to form an IPFS network based on the terminal equipment, and resource downloading, content sharing and other applications are realized among the terminal equipment, the terminal equipment may quit the IPFS network due to deactivation or equipment failure, shutdown and other reasons, which will correspondingly cause data assets on the terminal equipment to quit the network, so that the service stability of the IPFS applied to the terminal equipment cannot be ensured, and the real-time online availability of data files cannot be ensured.
In order to overcome the defect, the present application further constructs a second network connected to the first network and composed of a plurality of storage servers, where each storage server in the second network is used as a node of the network, and corresponds to defining a node in the first network and composed of terminal devices as a common node.
When the first network does not have a first node satisfying the data condition due to a corresponding reason (for example, the terminal device with the target data exits from the first network and is no longer used as an effective node of the first network due to deactivation or device failure, shutdown, or the like), and accordingly the target data required cannot be hit from the first network, the target data required can be further hit and obtained from the super node of the second network.
For example, when a user needs to download a target application program that is not provided at the local end of the installation device from an application store, the data file of the target application program is preferentially hit and acquired from at least one first node (corresponding to at least one terminal device joining the first network) of the first network that meets the data condition, and if the first node that meets the data condition does not exist in the first network and the hit fails, the data file of the target application program is hit and acquired from a super node of the second network.
It should be noted that the super node in the second network is a storage server, which generally stores sufficient and comprehensive data resources and is generally online in real time, so that the service stability when the IPFS is applied to the terminal device can be ensured and the real-time online availability of the data source file can be ensured by combining the first network and the second network.
According to the above scheme, the resource processing method of the embodiment constructs a two-layer network architecture including a first network and a second network, where the first network includes a plurality of common nodes formed by terminal devices, and the second network includes a plurality of super nodes formed by storage servers; on the basis, the terminal equipment preferentially obtains the target data from the first network, and if the target data is not obtained, the terminal equipment obtains the required data from the second network. Therefore, the terminal equipment is used as the content distribution node, the required data is preferentially acquired from the common node formed by the terminal equipment, the traffic distribution of the storage server can be realized, the efficiency and the speed of network resource distribution can be effectively improved, and based on the double-layer network architecture, when a certain terminal equipment exits from the first network and cannot acquire the data on the terminal equipment, the required data can be further acquired from the super node of the second network, so that the stability of service and the real-time online availability of data files are ensured.
In an optional embodiment of the present application, when the terminal device joins the first network as a normal node in the first network, the processor 702 may further perform the following processing:
obtaining second node information corresponding to the common node in the first network; sending second node information to a target super node meeting node conditions in a second network, so that the super node records the second node information; receiving at least one piece of first node information fed back by the target super node; each first node information is used for indicating a common node formed by terminal equipment joining the first network; caching the at least one first node information.
The second node information at least includes a unique ID corresponding to the terminal device in the first network when the terminal device is used as a common node of the first network, and in addition, may also include, but is not limited to, a node name, a node address, a node number, and other information, where the unique ID corresponding to the terminal device is an identifier generated by the terminal device based on a rule when the terminal device first joins the first network, and the identifier is subsequently used as a unique identifier of the terminal device identity each time the terminal device joins the first network. Of course, in the specific implementation, the method is not limited to this, and a unique ID may be generated each time the terminal device joins the first network.
Optionally, the second network includes a master super node and a plurality of slave super nodes, and the master super node and the plurality of slave super nodes may specifically form the second network through a consensus algorithm (raft); the target super node that meets the node condition may be a master super node in the second network.
The slave super node in the second network is responsible for storing the data file, and the master super node in the second network, besides being responsible for storing the data file, may also be used for, but not limited to, being responsible for at least part of the following processes:
1) acquiring the latest data file from a third-party system, adding the latest data file into a second network, and ensuring the file availability based on a raft algorithm;
2) recording and maintaining a mapping table between the data file and a storage address (an address corresponding to a corresponding storage position in a master super node or a slave super node) in the second network;
3) hit of target data (hit of data from the master super node itself or from a slave super node), transmission or relay;
4) recording and maintaining node information of each common node in the first network;
5) and pushing a common node information set (such as a common node information list) in the first network to a common node in the first network.
Therefore, after the terminal device joins the first network to become a common node of the first network and obtains corresponding second node information, the second node information is sent to the main super node of the second network to inform the main super node that a new common node is generated in the first network, and the main super node updates the second node information to a node information set (such as a node information list) maintained for the first network.
Optionally, after the terminal device sends the second node information to the master super node of the second network, the master super node feeds back, to the terminal device, at least one piece of first node information corresponding to at least one common node in the first network based on the second node information of the terminal device, for example, a list of all or part of node information of common nodes in the current first network may be fed back to the terminal device.
As another implementation manner, after sending the second node information to the master super node of the second network, the terminal device may further continue to send a node information acquisition request to the master super node, and the master super node responds to the request and feeds back, to the terminal device, at least one piece of first node information corresponding to at least one common node in the first network based on the second node information of the terminal device.
After the terminal device obtains the at least one piece of first node information, for example, after obtaining the whole or partial node information list, it can determine which common nodes exist in the first network based on the obtained node information, thereby facilitating applications such as in-network resource downloading and content sharing with corresponding common nodes in the first network.
Then, the terminal device caches at least one piece of first node information fed back by the master super node of the second network, for example, caches the received node information list. It is easy to understand that the second node information of the terminal device can also be carried by the master super node of the second network and pushed to other common nodes in the first network in the node information list. In this way, each common node joining the first network maintains a node information set (such as a node information list, but may also be in a non-list form, such as a tree structure form, a topological graph structure form, and the like) corresponding to at least a part of the common nodes in the first network, and on this basis, applications such as content sharing, resource downloading, and the like can be performed between the common nodes in the first network based on the maintained node information list.
In an alternative embodiment of the present application, the processor 702 may further implement its functions through the following processes:
when detecting that the activation condition is met, joining a first network as a common node in the first network; sending a data acquisition request to at least part of the common nodes indicated by the at least one piece of first node information; if at least one first node meeting the data condition exists in at least part of the nodes, target data fed back by the at least one first node meeting the data condition is obtained; if the first network does not have a first node meeting the data condition, sending a data acquisition request to a main super node in a second network; if the target data indicated by the data acquisition request is stored in the main super node, receiving the target data fed back by the main super node; and if the target data is not stored in the master super node, receiving the target data fed back by the slave super node of the second network, or receiving the target data relayed and transmitted by the master super node.
The activation condition may be, but is not limited to, any one of the following conditions:
the first condition is as follows: detecting that the terminal equipment enters a specific application;
and a second condition: detecting the starting of the terminal equipment;
for the above condition one, typically, for example, if the terminal device is detected to enter the application store, it indicates that the activation condition is met, and the node is automatically started to join the terminal device in the first network as its normal node.
For the second condition, but not limited to, a boot code may be integrated in a ROM (Read-Only Memory) of the terminal device, and once the device is booted (for example, a mobile phone is booted, a computer is booted, and the like), it indicates that the activation condition is met, and the node is automatically booted based on the boot code integrated in the ROM, and the terminal device is added to the first network as a normal node thereof.
After joining the first network as a normal node of the first network, as described above, the terminal device maintains a node information set of the normal node based on at least one piece of first node information pushed by the master super node of the second network.
On this basis, if the terminal device needs to obtain the target data, each common node existing in the first network may be determined based on the information set, and a data obtaining request for obtaining the target data may be sent to all or part of the common nodes indicated by each piece of first node information in the information set.
For example, when a user needs to download and install an application from an application store, the application store may preferentially search and acquire application data files from a first network formed by a plurality of terminal devices, and may specifically send request information for acquiring target data to all or part of common nodes indicated by each piece of first node information in a set based on a maintained first node information set.
If at least one first node meeting the data condition exists in each ordinary node receiving the request, that is, if at least one first node including at least part of the target data exists in each ordinary node receiving the request, it indicates that a data source of the target data exists in the first network, so that the target data can be acquired from the at least one first node meeting the data condition.
The method may download all/complete data files of the target data from one first node based on the actual holding condition of the first node on the data resource in the first network, or download different partial data in the target data from a plurality of first nodes respectively, and splice/integrate the obtained partial data to finally obtain all/complete data files of the target data.
When content is shared among the common nodes in the first network, sources of the shared data content may include, but are not limited to, the following:
1) the terminal equipment actively downloads and caches/stores the data content from the network;
2) hot data content which is pushed and cached/stored in the terminal equipment by a network;
3) when the first network queries and synchronizes the file list newly added to the second network from the second network periodically or based on condition triggering, caching/storing the corresponding file content of the corresponding terminal device based on a set strategy (such as a mode of sharing and the like).
On the contrary, if the first node meeting the data condition does not exist in the first network, it indicates that the data source of the target data does not exist in the first network, and in this case, the data acquisition request for acquiring the target data is continuously sent to the main super node in the second network.
After the main super node obtains the request, the storage address of the target data indicated by the request is determined based on the corresponding relation between the pre-stored data and the address, and the target data required by the hit of the storage address is further determined based on the storage address.
Wherein the target data may be stored in the master super node or in the corresponding slave super node. If the target data is stored in the main super node, the terminal device may receive the target data fed back by the main super node.
If the target data is not stored in the master super node, that is, the target data is stored in the slave super node, the terminal device may receive the target data fed back from the slave super node, where the target data is stored.
Under some conditions, based on the network architecture design, the slave super node in the second network can only perform data interconnection in the network of the second network and cannot perform data interaction with the external network equipment, that is, the whole second network realizes interaction with other networks through the master super node, and under the conditions, the terminal equipment can receive the target data transmitted by the master super node by relaying the target data of the slave super node.
In the embodiment, a first network based on terminal equipment is constructed, the terminal equipment is used as a content distribution node in the network, and a second network connected with the first network is constructed at the same time, when the terminal equipment needs to acquire target data, required data is preferentially acquired from a common node formed by the terminal equipment in the first network, so that traffic distribution can be performed on a storage server, the efficiency and the speed of network resource distribution can be effectively improved, and based on the double-layer network architecture, when a certain terminal equipment exits from the first network and cannot acquire the data on the terminal equipment, the required data can be further acquired from a super node of the second network, the stability of service is ensured, and the real-time online availability of file data is ensured.
In an alternative embodiment of the present application, the processor 702 may be further configured to:
detecting node states of common nodes indicated by each piece of cached first node information; if the common node indicated by the first node information is in a survival state, maintaining the cached first node information; and if the common node indicated by the first node information is in the non-survival state, clearing the first node information.
The node states of the normal nodes in the first network include two types: an active state and an inactive state. When the terminal device meets the activation condition and joins the first network, the node state of the terminal device enters the activation state, and when the user deactivates (for example, the user performs deactivation operation in an application store or in an information setting application of the terminal device), or exits a specific application (for example, exits the application store), or the device is turned off, has a fault, and the like, the node state of the terminal device becomes the non-activation state.
Therefore, the information of the invalid node in the inactive state may exist in the first node information set maintained by each common node in the first network, which brings disadvantages to content sharing among the common nodes and cannot be located and routed to the valid node based on the invalid node information.
In order to ensure the validity of each piece of first node information in a first node information set maintained by each common node of the first network, so that each piece of first node information can indicate an active node in an active state, in this embodiment, the common node where the terminal device is located further detects a node state of the common node indicated by each piece of cached first node information.
Optionally, the common node where the terminal device is located periodically sends a heartbeat packet to each of other common nodes indicated by the maintained first node information set, if response information of the common node indicated by some first node information can be received within a set time period, it indicates that the common node indicated by the first node information is in an activated state, and is a valid node, and if response information of the common node indicated by the first node information is not received within the set time period, it indicates that the common node indicated by the first node information is in an inactivated state, and is an invalid node,
If the common node indicated by the certain first node information is in the activated state through detection, the first node information is kept cached in the terminal equipment.
On the contrary, if the common node indicated by the first node information is in an inactive state, the common node is removed from the information set of the first node information maintained by the terminal device, and the first node information is not cached any more.
In this embodiment, by detecting the node state of the common node indicated by each piece of cached first node information and updating the cache based on the detected node state, each piece of first node information cached on the terminal device serving as the common node of the first network can be made to be valid information and can indicate the corresponding common node in the activated state in the first network, so that effective node location and routing support can be provided for applications such as content sharing and resource downloading among the common nodes in the first network.
In addition, in an optional embodiment of the present application, the terminal device further includes an agent, and the terminal device executes the function of implementing the processor 702 by running the agent.
Specifically, a proxy (Sidecar) is implemented on the terminal device in advance.
After the terminal device is added into the first network to be a common node of the first network, the proxy is utilized to package various node functions required when the terminal device is used as a native node of the first network.
For example, adding the terminal device a to the IPFS content distribution system to make it become the IPFS native node Peer a of the IPFS content distribution system, and encapsulating, in the proxy Sidecar of the terminal device a, various node functions that the IPFS native node Peer a needs to possess, where the encapsulated node functions may include but are not limited to: data discovery oriented to a first network and a second network, traffic management (throttling, downgrading, fusing), content sharing control inside the first network, information interaction control with the second network, and the like. As shown in fig. 6, the service grid is used to automatically discover and schedule resources in the first network and the second network through a network layer (network stack), so that the service stability of the content sharing service for the terminal device can be ensured, the hit rate of the user when downloading required data is increased, and the experience of the user when downloading resources is greatly improved.
In the embodiment, the terminal device is used as a content distribution node of the first network, so that the efficiency and the speed of network resource distribution are improved, meanwhile, based on the second network formed by the storage server, the service stability when the IPFS operates on the terminal device is ensured, the real-time online availability of the data file can be ensured, and in addition, the service grid is realized on the terminal device, so that the IPFS can reach the availability of a production level.

In the terminal device as the common node of the first network 801, the target data is obtained by at least one first node satisfying the data condition in the first network 801, and if the first node satisfying the data condition does not exist in the first network, the target data is obtained by a super node in the second network.
