However, in practice, it is found that, for a new client node which is first accessed, there is usually no seed file and the new client node cannot be accessed, and for a client node which is not first accessed, because the quality of the network node in the seed file cannot be guaranteed and the generation time of the seed file is generally different, there may be some network nodes which have been offline or are not connected.
Therefore, the network access efficiency of the client node is lower by using the network access mode of the seed file.

In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a preferred embodiment of a method for accessing a node. The order of the steps in the flowchart may be changed, and some steps may be omitted.
And S11, starting the equipment to be installed.
In the invention, when the starting instruction is received, the equipment to be installed can be started in response to the starting instruction.
The equipment to be installed is equipment which needs to be installed according to a client.
And S12, acquiring the downloading mode of the client of the equipment to be installed.
The downloading mode comprises standard channel downloading or non-standard channel downloading.
Wherein, the standard channel may be an authoritative location where the installation document is originally published, such as an official website, and the non-standard channel may be a location where the installation document is published without any authority, such as any ordinary webpage.
And S13, if the downloading mode is standard channel downloading, acquiring a first node configuration list created for the equipment to be installed.
The network nodes in the first node configuration list are stable nodes configured according to the current Internet Protocol (IP) area and/or operator network information of the equipment to be installed.
In the invention, the official website client records and counts the node information of the network nodes which are stably online for a long time in advance, such as 30 days x 24 hours. In addition, the network nodes which are statistically stable and online can be divided according to the geographic region of Internet Protocol (IP) and the network information of the operator. When the official network client detects that the equipment to be installed is downloaded from the official network, the current IP area and the operator network information of the equipment to be installed can be obtained, and the network node which is the same as the IP area and/or the operator network information of the equipment to be installed is selected from the counted multiple stable online network nodes. Then, a first node configuration list may be created for the device to be installed according to a preset priority. Wherein, the priority order is as follows in sequence: the same IP area and operator network information, the same IP area, the same operator network information, random.
For example, assuming that the capacity of the first node configuration list is S, the number of network nodes that are the same as the IP area of the device to be installed and the operator network information is a, the number of network nodes that are the same as the IP area of the device to be installed is B, and the number of network nodes that are the same as the operator network information of the device to be installed is C, first determining whether a is greater than or equal to S, if a is greater than or equal to S, randomly selecting S network nodes from the a network nodes to form the first node configuration list, if a is less than S, calculating a difference D between S and a, randomly selecting D network nodes from the B network nodes to form the first node configuration list together with a network nodes, and so on, if the sum of A, B, C is less than S, randomly selecting network nodes from other network nodes (i.e., network nodes that are not the same as the IP area of the device to be installed and the operator network information) to supplement the network nodes) And together form a first node configuration list.
In this way, the configuration is optimized. The official website client can create a first node configuration list matched with the equipment to be installed aiming at different equipment to be installed, so that the subsequent equipment to be installed can quickly and randomly select a certain network node from the first node configuration list, establish connection with the certain network node and join the network as soon as possible.
S14, after the device to be installed installs the client, selecting a first network node from the first node configuration list.
In the invention, after the device to be installed installs the client, the device to be installed with the client can be used as a client node. The client node may be an extranet node or an intranet node.
The outer network node is not provided with a router, has an outer network IP and can also be an inner network node which is successfully punched. The intranet nodes are network nodes which are not successful in punching and provided with routers, and are usually mounted in an intranet environment of a user, such as a guest playing cloud, a P2P Content Delivery Network (CDN) client, and the like. Due to the limitation of the local area network, the intranet nodes can directly access the extranet nodes, but the extranet nodes cannot directly access the intranet nodes anytime and anywhere.
In a Distributed Hash Table (DHT) network, after an intranet node is installed, a TCP long connection needs to be established with any other network node that has already been added to the DHT network, and when the connection is successful, the intranet node can be added to the DHT network. And the external network node can join the DHT network only by finding the external network node by other nodes.
In the invention, after the device to be installed with the client becomes the client node, the client node can select the first network node from the first node configuration list. Optionally, the client node may randomly select a first network node from the first node configuration list, or, optionally, the client node may select a first network node arranged at the forefront from the first node configuration list, which is not limited in the embodiment of the present invention.
And S15, establishing connection with the first network node, and adding the first network node into the DHT network.
In the present invention, the client node and all the first network nodes are located in a decentralized Distributed Hash Table (DHT) network, and the client node and all the first network nodes may form a peer to peer (P2P) network.
Specifically, the client node may send a connection request to the first network node, and after receiving the connection request, the first network node may attempt to establish connection with the client node, and if the connection is successful, the client node may join the DHT network, and then may communicate with a network node in the DHT network.
As an optional implementation, the method further comprises:
acquiring node information of each network node in the first node configuration list every other first preset period;
and deleting the network nodes in the unstable state from the first node configuration list according to the node information of each network node, and updating the first node configuration list.
In this embodiment, since the states of the network nodes in the first node configuration list may change, for example, some network nodes may go down, some network nodes may fail, and these unstable network nodes are unable to establish a connection with the client node, that is, these unstable network nodes are unreliable nodes.
After the client node joins the DHT network, it needs to periodically check the reliability of each network node in the first node configuration list. Specifically, the node information of each network node in the first node configuration list may be obtained at intervals of a first preset period (for example, every hour), where the node information may include, but is not limited to, an online/offline state of a node, a fault state of a node, an operating state of a node, and the like. Further, according to the node information of each network node, the network node in an unstable state may be deleted from the first node configuration list, so as to update the first node configuration list, so that the network node in the first node configuration list is a reliable stable node.
As an optional implementation, the method further comprises:
judging whether the number of the network nodes in the updated first node configuration list reaches a preset number threshold value or not;
if the number of the network nodes in the updated first node configuration list does not reach a preset number threshold, detecting network nodes meeting preset requirements from the DHT network;
and adding the network nodes meeting the preset requirements into the first node configuration list.
In this embodiment, after the first node configuration list is updated, since some network nodes are deleted, the number of network nodes in the updated first node configuration list is not saturated, that is, the number of network nodes in the updated first node configuration list does not reach a preset number threshold (for example, 100), and at this time, network nodes need to be supplemented.
Specifically, the client node may detect a network node meeting a preset requirement from the DHT network, and add the network node meeting the preset requirement to the first node configuration list. During detection, network nodes with the same IP area as the client node and the same network information of an operator are preferentially detected, if the number is not enough, the network nodes with the same IP area as the client node are detected, if the number is not enough, the network nodes with the same network information of the operator as the client node are further detected, and if the number is not enough, other network nodes (namely the network nodes with the same IP area as the client node and the same network information of the operator) are randomly detected until the number of the supplemented network nodes and the number of the network nodes in the first node configuration list which are updated before are saturated.
As an optional implementation, the method further comprises:
if the connection with the first network node fails, selecting a second network node from the first node configuration list after a preset time length;
and establishing connection with the second network node and adding the second network node into the DHT network.
In this embodiment, when the connection between the client node and the first network node fails, in order to avoid the connection failure caused by the current network environment instability, a backoff policy needs to be enabled, specifically, a preset time duration (for example, 5S) may be waited, after the preset time duration, a second network node is selected from the first node configuration list, and a connection is established with the second network node and is added to the DHT network. Similarly, if the client node fails to connect with a second network node, other network nodes may be selected from the first node configuration list after a preset time period and attempt to establish connections with other second network nodes.
As an optional implementation, the method further comprises:
if the connection with each network node in the first node configuration list is failed, or the networking time of the client node exceeds a preset time threshold and the client node is not networked, acquiring node information of an alternative node;
and establishing connection with the alternative node according to the node information of the alternative node, and adding the connection into the DHT network.
In this embodiment, a case that the connection between the client node and all network nodes in the first node configuration list is failed may occur, or a case that the networking time of the client node is long (for example, the networking time is 3min) but the client node is still not yet connected to the network may occur, where these cases indicate that the network nodes in the first node configuration list do not meet the connection requirement currently, and in order to enable the client node to join the network as soon as possible, node information of a preset alternative node may be obtained, where the alternative node is a node with a stable state, and is always in an online state, and does not go offline, and a failure does not occur. The client node may establish a connection with the alternative node according to the node information of the alternative node to join the DHT network as soon as possible.
As an optional implementation, the method further comprises:
if the downloading mode is non-standard channel downloading, acquiring a general second node configuration list, wherein the network nodes in the second node configuration list are stable nodes covering all areas and operator networks;
after the client is installed on the equipment to be installed, selecting a third network node from the second node configuration list;
and establishing connection with the third network node and adding the third network node into the DHT network.
In this embodiment, the device to be installed may be used across different operator networks nationwide, and a common second node configuration list may be configured in advance for all network nodes, that is, the second node configuration list is fixed for all network nodes, where the network nodes in the second node configuration list are stable nodes covering all areas and operator networks. Specifically, all stable nodes may be counted first, then divided according to the IP area and the operator network information, and then nodes are randomly selected, so that the last selected node covers all areas and all large operator networks as much as possible, thereby preventing the problem of long networking time or network access failure due to network unavailability between different areas or different operators.
When the downloading mode is the downloading through a non-standard channel, the device to be installed can obtain a general second node configuration list, and after the device to be installed installs the client, a third network node is selected from the second node configuration list, is connected with the third network node, and is added into the DHT network.
In this way, since the network node in the second node configuration list is not configured for the device to be installed but is a general configuration list, after the device to be installed installs the client, it may need to attempt to connect to the network node in the second node configuration list many times.
As an optional implementation, the method further comprises:
acquiring node information of each network node in the second node configuration list every other second preset period;
deleting the network nodes in the unstable state from the second node configuration list according to the node information of each network node;
for each network node in the deleted second node configuration list, judging whether the IP area of the network node is the same as the IP area of the client node, and judging whether the operator network information of the network node is the same as the operator network information of the client node;
and if the IP area of the network node is different from the IP area of the client node, and the operator network information of the network node is different from the operator network information of the client node, deleting the network node from the second node configuration list, and updating the second node configuration list.
In this embodiment, since the network nodes in the second node configuration list are not configured for the client node, but are a general configuration list, and the network nodes in the second node configuration list may change over time, the network nodes are in an unstable state, such as some network nodes go down and some network nodes go down. Therefore, after the client node joins the DHT network, the network nodes in the second node configuration list can be updated and maintained to obtain the configuration list meeting the needs of the client node.
Specifically, the node information of each network node in the second node configuration list may be obtained every second preset period (for example, every hour), and the network node in an unstable state is deleted from the second node configuration list according to the node information of each network node, and after the unstable network node is removed, a network node matched with the IP area and the operator network information of the network node is further selected for each network node in the deleted second node configuration list. Specifically, it may be determined whether the IP area of the network node is the same as the IP area of the client node, and whether the operator network information of the network node is the same as the operator network information of the client node, and if the IP area of the network node is not the same as the IP area of the client node, and the operator network information of the network node is not the same as the operator network information of the client node, the network node is deleted from the second node configuration list, and the second node configuration list is updated. The updated second node configuration lists are all stable network nodes, and are all configured according to the IP area and/or operator network information of the client node, so that the configuration is better.
Optionally, when the downloading manner is downloading through a non-standard channel, it is also necessary to determine whether the number of network nodes in the updated second node configuration list is saturated, and if not, it is necessary to detect a network node meeting a preset requirement, so as to perform node supplementation on the updated second node configuration list. Reference may be made in particular to the analogous description above.
Optionally, when the downloading manner is downloading through a non-standard channel, if the connection with the third network node fails and a preset time period needs to be waited for, a fourth network node is selected from the second node configuration list again, and a connection is established with the fourth network node and is added to the DHT network. Reference may be made in particular to the analogous description above.
Optionally, when the downloading manner is downloading through a non-standard channel, if connection with each network node in the second node configuration list fails, or the networking time of the client node exceeds a preset time threshold and the client node is not networked, node information of an alternative node may be obtained; and establishing connection with the alternative node according to the node information of the alternative node, and adding the connection into the DHT network. Reference may be made in particular to the analogous description above.
In the method flow described in fig. 1, when any one of the devices to be installed is started, the device to be installed may directly select any one of the first network nodes from the first node configuration list, and after the device to be installed installs the client, the device to be installed with the client may serve as a client node.
The above description is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and it will be apparent to those skilled in the art that modifications may be made without departing from the inventive concept of the present invention, and these modifications are within the scope of the present invention.
Referring to fig. 2, fig. 2 is a functional block diagram of a preferred embodiment of a node network access device according to the present invention.
In some embodiments, the node networking means operates in a client node. The node network access device may comprise a plurality of functional modules consisting of program code segments. Program code of various program segments in the node network access device may be stored in the memory and executed by the at least one processor to perform some or all of the steps of the node network access method described in fig. 1.
In this embodiment, the node network access device may be divided into a plurality of functional modules according to the functions executed by the node network access device. The functional module may include: an acquisition module 201, a selection module 202 and a connection module 203. The module referred to herein is a series of computer program segments capable of being executed by at least one processor and capable of performing a fixed function and is stored in memory. In some embodiments, the functions of the modules will be described in detail in this embodiment.
The obtaining module 201 is configured to obtain a downloading manner of a client of the device to be installed.
In the invention, when the starting instruction is received, the equipment to be installed can be started in response to the starting instruction.
The equipment to be installed is equipment which needs to be installed according to a client.
The downloading mode comprises standard channel downloading or non-standard channel downloading.
Wherein, the standard channel may be an authoritative location where the installation document is originally published, such as an official website, and the non-standard channel may be a location where the installation document is published without any authority, such as any ordinary webpage.
The obtaining module 201 is further configured to obtain a first node configuration list created for the device to be installed if the downloading manner is downloading through a standard channel, where a network node in the first node configuration list is a stable node configured according to a current internet protocol IP area of the device to be installed and/or network information of an operator.
The network nodes in the first node configuration list are stable nodes configured according to the current Internet Protocol (IP) area and/or operator network information of the equipment to be installed.
In the invention, the official website client records and counts the node information of the network nodes which are stably online for a long time in advance, such as 30 days x 24 hours. The statistical stable online network nodes can also be divided according to the Internet Protocol (IP) geographical area and the operator network information. When the official network client detects that the equipment to be installed is downloaded from the official network, the current IP area and the operator network information of the equipment to be installed can be obtained, and the network node which is the same as the IP area and/or the operator network information of the equipment to be installed is selected from the counted multiple stable online network nodes. Then, a first node configuration list may be created for the device to be installed according to a preset priority. Wherein, the priority order is as follows in sequence: the same IP area and operator network information, the same IP area, the same operator network information, random.
For example, assuming that the capacity of the first node configuration list is S, the number of network nodes that are the same as the IP area of the device to be installed and the operator network information is a, the number of network nodes that are the same as the IP area of the device to be installed is B, and the number of network nodes that are the same as the operator network information of the device to be installed is C, first determining whether a is greater than or equal to S, if a is greater than or equal to S, randomly selecting S network nodes from the a network nodes to form the first node configuration list, if a is less than S, calculating a difference D between S and a, randomly selecting D network nodes from the B network nodes to form the first node configuration list together with a network nodes, and so on, if the sum of A, B, C is less than S, randomly selecting network nodes from other network nodes (i.e., network nodes that are not the same as the IP area of the device to be installed and the operator network information) to supplement the network nodes) And together form a first node configuration list.
In this way, the configuration is optimized. The official website client can create a first node configuration list matched with the equipment to be installed aiming at different equipment to be installed, so that the subsequent equipment to be installed can quickly and randomly select a certain network node from the first node configuration list, establish connection with the certain network node and join the network as soon as possible.
A selecting module 202, configured to select a first network node from the first node configuration list after the to-be-installed device installs the client.
In the invention, after the device to be installed installs the client, the device to be installed with the client can be used as a client node. The client node may be an extranet node or an intranet node.
The outer network node is not provided with a router, has an outer network IP and can also be an inner network node which is successfully punched. The intranet nodes are network nodes which are not successful in punching and provided with routers, and are usually mounted in an intranet environment of a user, such as a guest playing cloud, a P2P Content Delivery Network (CDN) client, and the like. Due to the limitation of the local area network, the intranet nodes can directly access the extranet nodes, but the extranet nodes cannot directly access the intranet nodes anytime and anywhere.
In a Distributed Hash Table (DHT) network, after an intranet node is installed, a TCP long connection needs to be established with any other network node that has already been added to the DHT network, and when the connection is successful, the intranet node can be added to the DHT network. And the external network node can join the DHT network only by finding the external network node by other nodes.
In the invention, after the device to be installed with the client becomes the client node, the client node can select the first network node from the first node configuration list. Optionally, the client node may randomly select a first network node from the first node configuration list, or, optionally, the client node may select a first network node arranged at the forefront from the first node configuration list, which is not limited in the embodiment of the present invention.
A connection module 203, configured to establish a connection with the first network node, and add the connection to the DHT network.
In the present invention, the client node and all the first network nodes are located in a decentralized Distributed Hash Table (DHT) network, and the client node and all the first network nodes may form a peer to peer (P2P) network.
Specifically, the client node may send a connection request to the first network node, and after receiving the connection request, the first network node may attempt to establish connection with the client node, and if the connection is successful, the client node may join the DHT network, and then may communicate with a network node in the DHT network.
Optionally, the obtaining module 201 is further configured to obtain node information of each network node in the first node configuration list every other first preset period;
the node network access device may further include:
and the updating module is used for deleting the network nodes in the unstable state from the first node configuration list according to the node information of each network node and updating the first node configuration list.
In this embodiment, since the states of the network nodes in the first node configuration list may change, for example, some network nodes may go down, some network nodes may fail, and these unstable network nodes are unable to establish a connection with the client node, that is, these unstable network nodes are unreliable nodes.
After the client node joins the DHT network, it needs to periodically check the reliability of each network node in the first node configuration list. Specifically, the node information of each network node in the first node configuration list may be obtained at intervals of a first preset period (for example, every hour), where the node information may include, but is not limited to, an online/offline state of a node, a fault state of a node, an operating state of a node, and the like. Further, according to the node information of each network node, the network node in an unstable state may be deleted from the first node configuration list, so as to update the first node configuration list, so that the network node in the first node configuration list is a reliable stable node.
Optionally, the node network access apparatus may further include:
the judging module is used for judging whether the number of the network nodes in the updated first node configuration list reaches a preset number threshold value;
the detection module is used for detecting network nodes meeting preset requirements from the DHT network if the number of the network nodes in the updated first node configuration list does not reach a preset number threshold;
and the adding module is used for adding the network nodes meeting the preset requirements into the first node configuration list.
In this embodiment, after the first node configuration list is updated, since some network nodes are deleted, the number of network nodes in the updated first node configuration list is not saturated, that is, the number of network nodes in the updated first node configuration list does not reach a preset number threshold (for example, 100), and at this time, network nodes need to be supplemented.
Specifically, the client node may detect a network node meeting a preset requirement from the DHT network, and add the network node meeting the preset requirement to the first node configuration list. During detection, network nodes with the same IP area as the client node and the same network information of an operator are preferentially detected, if the number is not enough, the network nodes with the same IP area as the client node are detected, if the number is not enough, the network nodes with the same network information of the operator as the client node are further detected, and if the number is not enough, other network nodes (namely the network nodes with the same IP area as the client node and the same network information of the operator) are randomly detected until the number of the supplemented network nodes and the number of the network nodes in the first node configuration list which are updated before are saturated.
Optionally, the selecting module 202 is further configured to select, if the connection with the first network node fails, a second network node from the first node configuration list after a preset time period;
the connection module 203 is further configured to establish a connection with the second network node, and join the second network node in the DHT network.
In this embodiment, when the connection between the client node and the first network node fails, in order to avoid the connection failure caused by the current network environment instability, a backoff policy needs to be enabled, specifically, a preset time duration (for example, 5S) may be waited, after the preset time duration, a second network node is selected from the first node configuration list, and a connection is established with the second network node and is added to the DHT network. Similarly, if the client node fails to connect with a second network node, other network nodes may be selected from the first node configuration list after a preset time period and attempt to establish connections with other second network nodes.
Optionally, the obtaining module 201 is further configured to obtain node information of an alternative node if the connection with each network node in the first node configuration list fails, or the networking time of the client node exceeds a preset time threshold and the client node is not networked;
the connection module 203 is further configured to establish a connection with the candidate node according to the node information of the candidate node, and add the connection to the DHT network.
In this embodiment, a case that the connection between the client node and all network nodes in the first node configuration list is failed may occur, or a case that the networking time of the client node is long (for example, the networking time is 3min) but the client node is still not yet connected to the network may occur, where these cases indicate that the network nodes in the first node configuration list do not meet the connection requirement currently, and in order to enable the client node to join the network as soon as possible, node information of a preset alternative node may be obtained, where the alternative node is a node with a stable state, and is always in an online state, and does not go offline, and a failure does not occur. The client node may establish a connection with the alternative node according to the node information of the alternative node to join the DHT network as soon as possible.
Optionally, if the downloading manner is downloading through a non-standard channel, the obtaining module 201 is further configured to obtain a general second node configuration list, where a network node in the second node configuration list is a stable node covering all areas and operator networks;
the selecting module 202 is further configured to select a third network node from the second node configuration list after the client is installed in the device to be installed;
the connection module 203 is further configured to establish a connection with the third network node, and join the third network node in the DHT network.
In this embodiment, the device to be installed may be used across different operator networks nationwide, and a common second node configuration list may be configured in advance for all network nodes, that is, the second node configuration list is fixed for all network nodes, where the network nodes in the second node configuration list are stable nodes covering all areas and operator networks. Specifically, all stable nodes may be counted first, then divided according to the IP area and the operator network information, and then nodes are randomly selected, so that the last selected node covers all areas and all large operator networks as much as possible, thereby preventing the problem of long networking time or network access failure due to network unavailability between different areas or different operators.
When the downloading mode is downloading through a non-standard channel, the device to be installed may obtain a general second node configuration list, and after the device to be installed installs the client, select a third network node from the second node configuration list, establish a connection with the third network node, and join the third network node in the DHT network.
In this way, since the network node in the second node configuration list is not configured for the device to be installed but is a general configuration list, after the device to be installed installs the client, it may need to attempt to connect to the network node in the second node configuration list many times.
Optionally, the obtaining module 201 is further configured to obtain node information of each network node in the second node configuration list every second preset period;
a deleting module, configured to delete the network node in an unstable state from the second node configuration list according to the node information of each network node;
a judging module, configured to judge, for each network node in the deleted second node configuration list, whether an IP area of the network node is the same as an IP area of the client node, and whether operator network information of the network node is the same as operator network information of the client node;
the deleting module is further configured to delete the network node from the second node configuration list and update the second node configuration list if the IP area of the network node is different from the IP area of the client node and the operator network information of the network node is different from the operator network information of the client node.
In this embodiment, since the network nodes in the second node configuration list are not configured for the client node, but are a general configuration list, and the network nodes in the second node configuration list may change over time, the network nodes are in an unstable state, such as some network nodes go down and some network nodes go down. Therefore, after the client node joins the DHT network, the network nodes in the second node configuration list can be updated and maintained to obtain the configuration list meeting the needs of the client node.
Specifically, the node information of each network node in the second node configuration list may be obtained every second preset period (for example, every hour), and the network node in an unstable state is deleted from the second node configuration list according to the node information of each network node, and after the unstable network node is removed, a network node matched with the IP area and the operator network information of the network node is further selected for each network node in the deleted second node configuration list. Specifically, it may be determined whether the IP area of the network node is the same as the IP area of the client node, and whether the operator network information of the network node is the same as the operator network information of the client node, and if the IP area of the network node is not the same as the IP area of the client node, and the operator network information of the network node is not the same as the operator network information of the client node, the network node is deleted from the second node configuration list, and the second node configuration list is updated. The updated second node configuration lists are all stable network nodes, and are all configured according to the IP area and/or operator network information of the client node, so that the configuration is better.
Optionally, when the downloading manner is downloading through a non-standard channel, it is also necessary to determine whether the number of network nodes in the updated second node configuration list is saturated, and if not, it is necessary to detect a network node meeting a preset requirement, so as to perform node supplementation on the updated second node configuration list. Reference may be made in particular to the analogous description above.
Optionally, when the downloading manner is downloading through a non-standard channel, if the connection with the third network node fails and a preset time period needs to be waited for, a fourth network node is selected from the second node configuration list again, and a connection is established with the fourth network node and is added to the DHT network. Reference may be made in particular to the analogous description above.
Optionally, when the downloading manner is downloading through a non-standard channel, if connection with each network node in the second node configuration list fails, or the networking time of the client node exceeds a preset time threshold and the client node is not networked, node information of an alternative node may be obtained; and establishing connection with the alternative node according to the node information of the alternative node, and adding the connection into the DHT network. Reference may be made in particular to the analogous description above.
In the node network access apparatus described in fig. 2, when any one of the devices to be installed is started, the device to be installed may directly select any one of the first network nodes from the first node configuration list, and after the device to be installed installs the client, the device to be installed with the client may serve as the client node.
