Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a networking device of a hardware running environment according to an embodiment of the present invention.

As shown in fig. 1, the networking device may include: a processor 1001, such as a central processing unit (Central Processing Unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, a memory 1005. Wherein the communication bus 1002 is used to enable connected communication between these components. The user interface 1003 may include a Display, an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may further include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a Wireless interface (e.g., a Wireless-Fidelity (Wi-Fi) interface). The Memory 1005 may be a high-speed random access Memory (Random Access Memory, RAM) or a stable nonvolatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.

Those skilled in the art will appreciate that the structure shown in fig. 1 is not limiting of the networking device and may include more or fewer components than shown, or certain components may be combined, or a different arrangement of components.

As shown in fig. 1, an operating system, a network communication module, a user interface module, and a networking program may be included in the memory 1005 as one type of storage medium.

In the networking device shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the networking device of the present invention may be disposed in the networking device, where the networking device invokes a networking program stored in the memory 1005 through the processor 1001, and executes the networking method provided by the embodiment of the present invention.

An embodiment of the present invention provides a networking method, referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the networking method of the present invention.

In this embodiment, the networking method includes the following steps:

step S10: and searching the wireless signal of the upper-level routing equipment according to the wide area network interface when the wide area network interface of the network routing equipment to be assembled does not receive the IPv6 information sent by the upper-level routing equipment, so as to obtain at least one wireless signal.

It should be noted that, the execution body of the method of this embodiment may be a device having functions of network communication, route forwarding, and data forwarding, for example: the router, the home gateway, or the like may be other devices with the same or similar functions, and in this embodiment and the following embodiments, the device to be networked is described by taking the routing device as an example.

It should be noted that, in the conventional technology, the routing device is a default routing mode in the ad hoc network, and the router in the default mode does not have the function of a local built-in DHCPv6PD server, so that the terminal device connected with the routing device cannot obtain the IPv6 address.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a home ad hoc network in this embodiment, in a default mode, a router only has a function that a wide area network interface can obtain an IPv6 address, and even if the router device sends an allocation request of an IPv6 address prefix to a gateway, the gateway device does not have a prefix pool, and therefore cannot realize the function of allocating the IPv6 address prefix, so that a terminal connected to the router device cannot obtain the IPv6 address, and therefore cannot use the IPv6 function for networking.

In addition, DHCPv6 (Dynamic Host Configuration Protocol for IPv 6) is a protocol for dynamically allocating an IP address in an IPv6 network, DHCPv6 is an IPv6 version of a DHCP protocol in an IPv4 network, and a network administrator can automatically allocate an IP address, a DNS server, a default gateway, and other network configuration information to an IPv6 device through DHCPv6, so that a network management process is simplified.

The DHCPv6-PD (Prefix Delegation, prefix/delegate/proxy/delegate) prefix delegation mechanism is an extension of DHCPv6, the basic protocol being defined in RFC3633. Through a prefix delegation mechanism, a downstream prefix request client side puts forward a prefix allocation application to an upstream prefix delegation server, the prefix delegation server can allocate a proper prefix address to the prefix request client side, the downstream client side further and automatically subdivides the obtained prefix (generally less than 64 bits) into subnet network segments with the length of 64 bits of prefix, the subdivided address prefix is transmitted to a user link directly connected with a host through a Routing Announcement (RA), the address automatic configuration of the host is realized, and the attention is paid to transmitting network configuration parameters such as the address and the like from the server side to the IPv6 client side.

For convenience of explanation, the router is taken as an example of the network routing device to be assembled in the present embodiment and the following embodiments, and the gateway is taken as an example of the upper level routing device.

It should be understood that, due to the specificity of network routing, when the WAN port is detected to be activated and a legal IPv6 prefix can be obtained through a wired medium between the WAN interface of the to-be-assembled network routing device and the lan interface of the upper-level routing device, the wired medium is preferentially used to obtain the IPv6 prefix; if the wide area network interface of the to-be-networking routing equipment cannot acquire legal IPv6 prefix through the wired medium, the step of searching the wireless signal of the upper routing equipment according to the wide area network interface can be executed, so that the hybrid networking of wireless communication and wired communication is realized, and the networking efficiency is improved.

In a specific implementation, in order to enable the wide area network interface of the router device to realize the scanning function of the wireless signal, in this embodiment, the network routing device to be assembled needs to be modified to have a function of a "dynamic switching PD" server, where the "dynamic switching PD" server is different from a traditional DHCPv6PD server, and is a PD server, but the traditional DHCPv6PD server is manually configured, and an IPv6 prefix pool of the "dynamic switching PD" server is automatically generated by a system program without manual configuration intervention, and can be considered as a new extension function based on RFC-3633.

In a specific implementation, the searching for the wireless signal of the superior routing device may be scanning for the signal strength of a wireless service set identifier (Service Set Identifier, SSID) surrounding the network routing device to be assembled.

Step S20: and acquiring the signal strength of each wireless signal, and the prefix subnet length and the access level of the corresponding IPv6 prefix response of each wireless signal.

It will be appreciated that signal strength wireless signal strength refers to the strength of a wireless signal received by a device by a network to be assembled during wireless communication, typically represented by a signal strength indicator (Signal Strength Indicator, SSI) or a received signal strength indicator (Received Signal Strength Indicator, RSSI). The units of wireless signal strength may be decibel milliwatts (dBm) or a percentage; the prefix subnet length may be replaced by "accommodate 64-bit prefix number" in this embodiment, if the number of prefix numbers that can accommodate 64-bit prefix numbers is greater, meaning that the prefix subnet length is longer; the access level refers to the location of the wireless signal in the ad hoc network, generally, the closer to the broadband remote access server (Broadband Remote Access Server, BRAS), the higher the access level, and in this embodiment, the larger the prefix address, the higher the access level, because the prefix address is allocated according to the maximum priority allocation principle in this embodiment.

Step S30: and selecting a target wireless signal from the wireless signals according to at least one of the signal strength, the prefix subnet length and the access level.

In a specific implementation, since there may be multiple routing devices in the ad hoc network, as in the home ad hoc network described in fig. 3, the routing devices include a home gateway device, a home router, and a terminal with a routing function, and when the to-be-networked device needs to be connected to the ad hoc network, there may be multiple scanned wireless signals, but some routing devices cannot acquire an IPv6 address, which results in that the to-be-networked device connected to the routing device cannot acquire an IPv6 address, which affects the user experience.

In a specific implementation, an optimal target wireless signal can be selected from the scanned wireless signals according to at least one of signal strength, prefix subnet length and access level, so that network fluctuation is reduced, and user experience is experienced.

Step S40: and controlling the network routing equipment to be networked and the superior routing equipment to be networked according to the target wireless signal.

In a specific implementation, after determining the target wireless signal, the wireless signal broadcasted outwards by the upper-level routing device can control the wide area network interface of the network routing device to be assembled to be connected with the local area network interface of the upper-level routing device corresponding to the target wireless signal through a wired medium or a wireless signal, so that the network routing device to be assembled also has the functions of route forwarding, network data transmission, ipv6 address providing and the like.

According to the embodiment, the wide area network interface of the equipment to be networked and the local area network interface of the upper level routing equipment are connected through a wired medium, but when information related to an IPv6 function is not received, at least one wireless signal sent by the upper level routing equipment is searched through the wide area network interface, the signal intensity of each wireless signal and the prefix subnet length and the access level of the prefix response of each wireless signal corresponding to the IPv6 are obtained, a target wireless signal is selected from each wireless signal according to at least one of the signal intensity, the prefix subnet length and the access level, so that the equipment to be networked and the upper level routing equipment are controlled to be networked according to the target wireless signal, the IPv6 network is quickly connected, the connectable wireless signals are screened through the signal intensity of each wireless signal corresponding to the IPv6 prefix, the IPv6 networking effect with optimal network quality is obtained, the technical problem that terminal equipment in the prior art cannot obtain the IPv6 address in the self-organizing network is solved, and the communication quality of the network is improved.

Referring to fig. 4, fig. 4 is a schematic flow chart of a second embodiment of a networking method according to the present invention.

Based on the first embodiment, in this embodiment, the step S30 includes:

step S301: and sequencing the wireless signals according to the signal strength.

It should be noted that, the process of sorting the wireless signals according to the signal strength may be to sort the wireless signals according to the order of the signal strengths of the wireless signals, and preferentially perform the IPv6 prefix acquisition and judgment on the wireless signals with stronger signals scanned by the network routing device to be grouped.

Step S302: and determining the wireless signals to be selected with IPv6 prefix in each wireless signal.

It can be understood that, because the lan port of the upper routing device may implement a function of route forwarding, in order to avoid invalid signal connection, in this embodiment, it may be determined that a to-be-selected wireless signal with an IPv6 prefix exists in each wireless signal, so that the to-be-selected wireless signal is screened according to signal strength, to obtain a networking wireless signal that meets a requirement of a to-be-networking network routing device.

In a specific implementation, the embodiment may also preferably select a router (LAN port) with strong ssid signal strength and capable of acquiring an IPv6 prefix to access, but the ssid signal strength is strong, but the ssid signal is abandoned if the IPv6 prefix cannot be acquired, and then select the ssid signal with the next strongest signal to connect, and detect whether the IPv6 prefix can be acquired, until the IPv6 prefix can be acquired, and use the presently connected ssid signal as a target wireless signal, and connect to a local area network port corresponding to the target wireless signal.

Step S303: and selecting a target wireless signal from the wireless signals to be selected according to the sorting result, wherein the target wireless signal is the wireless signal to be selected with the IPv6 prefix and the maximum signal strength.

It can be understood that, since the device generally divides into different gear positions according to the signal strength when scanning the wireless signals, in the process of comparing and sorting the signal strengths, wireless signals with the same signal strength may appear, if the wireless signals with the same signal strength are connected, IPv6 prefixes may be obtained, and at this time, the target wireless signal to be connected to the device to be networked may be determined through at least one of the prefix subnet length and the access level of the wireless signals.

Further, after selecting the target wireless signal from the wireless signals to be selected according to the sorting result, the method further includes:

It should be noted that, in order to provide a better network communication effect, and enable the network routing device to be assembled to carry more networking terminal devices, the embodiment may determine the target wireless signal preferentially according to the length of the prefix subnet under the condition that the signal strength is the same.

Further, the determining the target wireless signal according to at least one of the prefix subnet length and the access level of each wireless signal to be selected includes:

comparing the prefix subnet lengths of the wireless signals to be selected;

In a specific implementation, if a plurality of wifi signals with the same signal intensity exist in the periphery and prefix subnets containing 64-bit prefix entries are different in length, a wide area network interface of a network to be grouped is preferentially selected to be accessed to a local area network interface of an upper-level routing device by the wifi signal corresponding to the prefix subnet containing more 64-bit prefix entries, because the prefix agent contains more 64-bit prefix entries, the router containing more downstream tandem routers can bear more networking users.

Further, the networking method further comprises:

and when the prefix subnetworks of the wireless signals to be selected are the same in length, determining a target wireless signal from the wireless signals to be selected according to the access level, wherein the target wireless signal is the wireless signal to be selected with the same signal strength, the same prefix subnetwork length and the highest access level.

In a specific implementation, if a plurality of wifi signals with the same signal intensity exist in the periphery and the prefix subnetwork length of the prefix subnetwork containing the number of the 64-bit prefix entries is the same, the network to be assembled is preferentially selected by the wide area network interface of the device to access the wifi signal with higher access level, namely, the closer the distance from the tree root in the tree network structure is, if the prefix agent splits the address, the largest 64-bit prefix is selected to be taken out for the interconnection address, and then the prefix subnetwork with the large prefix address represents higher access level.

In addition, since the wireless signal is not provided with security measures such as password verification and the like, namely the security problem is not considered, the wireless signal can be mainly used for emergency rescue or hot spot coverage scenes, and the ensured personnel can rob through the IPv6 network by wifi.

For example: the network routing device to be grouped receives three IPv6 prefixes with the same prefix from different routers or gateway devices: 2409:8020:1000:100c:/63, 2409:8020:1000:1008:/63, and 2409:8020:1000:1000:/63, then the prefix subnetwork 2409:8020:1000:100 c:/63 with a large prefix address IP is selected at this time to represent a higher access level, and this arrangement can enable the ad hoc network to avoid looping without manual configuration.

According to the embodiment, the optimal target wireless signal is selected from the wireless signals according to at least one of the signal strength, the prefix subnet length and the access level of the scanned wireless signals, so that the IPv6 network communication connection between the equipment to be networked and the upper-level routing equipment is realized, and the popularization rate of the IPv6 network is improved.

Referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of a networking method according to the present invention.

Based on the above second embodiment, a third embodiment of the networking method of the present invention is provided, and in this embodiment, before the step S10, the method further includes:

step S01: and sending an IPv6 prefix request to the upper-level routing equipment, and receiving a prefix response message fed back by the upper-level routing equipment based on the prefix request.

It should be noted that, the upper-level routing device may be a delegated server, a broadband remote access server, a gateway device, or a router according to the network routing device to be assembled, which is not limited in this embodiment.

Referring to fig. 6, fig. 6 is a timing diagram of networking in a home ad hoc network, so that when a device to be networked requests access, an IPv6 prefix or an IPv6 address is allocated to the device to be networked, and in this embodiment, an IPv6 prefix subnet pool is constructed in a storage space of an already-assembled routing device in the ad hoc network, so as to facilitate allocation of the IPv6 prefix or the IPv6 address.

Step S02: and splitting the IPv6 prefix in the prefix response message into a plurality of IPv6 prefix subnets.

It should be noted that splitting the IPv6 prefix field in the prefix response message refers to splitting according to the number of prefix bits, for example: referring to fig. 7, fig. 7 is a tree network topology diagram of a home network routing device, in the network topology, the length of an IPv6 prefix in a prefix response packet received by a primary router is 2409:8020:1000:1000:60, where for the prefix, the following prefix subnet splitting may be performed: (1) 1/60 subnetwork: 2409:8020:1000:1000:60; (2) 2/61 subnets: 2409:8020:1000:1000:61 and 2409:8020:1000:1008:61; (3) 4/62 subnetworks: 2409:8020:1000:1000:62:2409:8020:1000:1004:62:2409:8020:1000:1008:62 and 2409:8020:1000:100 c:62:1/62; (4) 8/63 subnetworks: 2409:8020:1000:1000:63, 2409:8020:1000:1002:63. (5) 16/64 subnets: 2409:8020:1000:1000:64-2409:8020:1000:100 f:64.

Step S03: and generating an IPv6 prefix subnet pool according to the plurality of IPv6 prefix subnets, selecting a target IPv6 prefix subnet from the IPv6 prefix subnet pool when receiving a networking request of the lower-level routing equipment, and feeding back the target IPv6 prefix subnet to the lower-level routing equipment.

In a specific implementation, the home gateway device sends an IPv6 prefix request, and according to a prefix response message returned by the upstream proxy server, automatically splits an idle IPv6 prefix which is not allocated to the home gateway device side into prefix subnets with different lengths, and when splitting, can keep the prefix subnets containing more 64-bit prefix entries as much as possible, and generate an IPv6 prefix pool in the built-in DHCPv6 dynamic conversion PD server.

After the IPv6 prefix pool is generated, if the prefix request of the DHCPv6 sent by the router of a certain port at the local area network side is responded by using the IPv6 prefix pool in the 'dynamic conversion PD' server, the prefix sub-network containing more 64-bit prefix entries is preferentially distributed outwards, so that the local area network side of the downstream home router can obtain the IPv6 prefix, and more routers or terminals can be conveniently carried.

Further, when generating the IPv6 prefix subnet pool, since the home gateway device may need to directly provide the IPv6 address service for other terminal devices, it may occupy an IPv6 address or an IPv6 prefix, and in order to improve the network utilization, the generating the IPv6 prefix subnet pool according to the multiple IPv6 prefix subnets includes:

acquiring the prefix subnet length of each IPv6 idle prefix subnet;

It should be noted that, the home gateway device may also need to provide an IPv6 network service for the terminal device, and in this embodiment, a prefix is reserved in the divided 64-bit prefix, and is used as an interconnection address of the home gateway device, where the interconnection address is represented by a 128-bit binary number in the IPv6 protocol, and is typically represented in hexadecimal number separated by a colon, and is used as a unique address for identifying and locating a computer or other network device in the internet.

Since the IPv6 prefix is 64 bits, in order to obtain the interconnection address (i.e., IPv6 address) of the home gateway device can be obtained in two ways: 1. stateless address auto-configuration (Stateless Address Autoconfiguration, SLAAC) stateless auto-allocation: at this time, m=0, the terminal host initiates a router request, the gateway allocates a 64-bit prefix to the terminal host through a Router Advertisement (RA) message, and the terminal host generates the post 64 bits according to the EUI64 algorithm and the like to synthesize a 128-bit IPv6 address; 2. DHCPv6 stateful automatic allocation: at this time, m=1, the end host initiates a non-temporary address authentication request to the proxy server, and the proxy server directly allocates 128-bit IPv6 address to the end host.

However, unlike the end hosts, the router or the home gateway device is not only required to apply an IPv6 address for the wide area network interface side to use, but also required to apply a prefix for the end hosts on the local area network interface side through an IPv6 address prefix request allocated to the prefix request router by default.

In this embodiment, the selection of the interconnection address may be selecting a minimum 64-bit prefix or a maximum 64-bit prefix, which is not particularly limited in this embodiment, and when different 64-bit prefixes are selected as the interconnection addresses, there is a difference between the access levels of the prefix addresses in the tree network tray, for example: when the maximum 64-bit prefix is used as the interconnection address (namely 2409:8020:1000:100f:/64) is used for the interconnection address), the plurality of IPv6 idle prefix subnets are respectively 1/61 subnets: 2409:8020:1000:1000:61, 1/62 subnetworks: 2409:8020:1000:1008:62, 1/63 subnetworks: 2409:8020:1000:100c::63/1/64 subnetworks: 2409:8020:1000:100e:/64.

In a specific implementation, in order to enable the routing device requesting networking to carry more routers or terminal devices, the embodiment may assign an IPv6 prefix to the routing device requesting networking according to the priority of the prefix subnet length.

The priority of the four IPv6 idle prefix subnets is 2409:8020:1000:1000:61 (8 64-bit prefix entries can be accommodated); priority 2: 2409:8020:1000:1008::62 (which can hold 4 64-bit prefix entries); priority 3: 2409:8020:1000:100c:63 (which can hold 2 64-bit prefix entries); priority 4: 2409:8020:1000:100e::64 (which can accommodate 1 64-bit prefix entry), wherein the prioritization is according to a rule that the shorter the length of the prefix subnet, the higher the priority, or is determined by the number of 64-bit prefix entries that can be accommodated, which is not particularly limited by the present embodiment.

In a specific implementation, when the home gateway receives a prefix request of DHCPv6 sent by a home router of a certain port on the LAN side, an IPv6 prefix pool is used to respond, and a prefix subnet containing more 64-bit prefix entries is preferentially allocated to the outside, so that the LAN side of a lower-level home router can obtain an IPv6 prefix, for example: if the LAN port receives the IA_PD request sent by the first router of the lower level, the highest priority 2409:8020:1000:1000:61 (which can hold 8 64-bit prefix entries) can be firstly allocated, so that the downstream router can further split the prefix; if the LAN port receives the prefix request sent by the second router at the lower level, the prefix with the highest priority is occupied, and then the 2 nd priority 2409:8020:1000:1008::62 (4 64-bit prefix entries can be accommodated) can be allocated; if the IA_PD request sent by the third router is received, the 3 rd priority 2409:8020:1000:100c:63 (which can hold 2 64-bit prefix entries) is allocated until there is no free IPv6 prefix.

If the wireless router receives the prefix request of the lower-level invalid router, the idle IPv6 prefix can be allocated according to the above process, which is not described in detail in this embodiment.

In a specific implementation, the number of routing devices requesting networking is large, so that the IPv6 prefix subnet pool is divided, and a prefix request can be sent to the upper-level routing device again to obtain more idle IPv6 prefix subnet prefixes.

Further, the subordinate router may include a prefix in the prefix request, as a hint to the delegated router, indicating that the requesting router wishes to be able to use the prefix, and when the requesting router identifies the delegated router, the requesting router uses the response message to populate the prefix request with the prefix. The lower level router may include one or more prefix options in the response message, and the upper level router returns the prefix and other information about the prefix request to the requesting router in the prefix options in the feedback message.

According to the embodiment, the IPv6 prefix subnet pool is constructed through the right lifting, so that when a next router requests to access the network, prefix subnets with the larger number of 64-bit prefix entries can be allocated, and the popularization rate of IPv6 is improved.

In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium stores a networking program, and the networking program realizes the steps of the networking method when being executed by a processor.
