Example 1
Fig. 1 is a flowchart of a gateway adjustment method according to a first embodiment of the present invention, where the method may be performed by a gateway adjustment device, the gateway adjustment device may be implemented in hardware and/or software, and the gateway adjustment device may be configured in an electronic device. Specifically, referring to fig. 1, the method specifically includes the following steps:
And 110, polling and checking the connection state of each wan interface in the target system every first set time interval, and determining the target wan interface as a default gateway if the connection state of the target wan interface is the connected state.
The first set time interval may be 30 seconds, 20 seconds, 60 seconds, or the like, which is not limited in this embodiment, and the target system may be an OpenWRT system or other embedded Linux systems, which is not limited in this embodiment.
In the Internet, a gateway refers to a network device for connecting two or more network segments, and a router is generally used as a gateway. In a TCP/IP network system, the gateway has the basic function of selecting the optimal outlet for forwarding the IP packet according to the network number and the subnet number of the destination IP address, so as to realize data communication across network segments. The gateway is sometimes also considered as this IP address with the data forwarding device, and the gateway should be in the same network segment as the IP address of its subnet. For example, there are a network a and a network B, the IP address range of the network a is "192.168.1.1-192.168.1.254", and the subnet mask is 255.255.255.0; the IP address range of network B is "192.168.2.1 to 192.168.2.254", and the subnet mask is 255.255.255.0. Without a router, TCP/IP communication is not possible between two networks, and even if two networks are connected to the same switch (or hub), the TCP/IP protocol determines that hosts in the two networks are in different networks according to a subnet mask (255.255.255.0). And to enable communication between the two networks, a gateway must be passed. If the host in the network A finds that the destination host of the data packet is not in the local network, the data packet is forwarded to its own gateway, then the gateway is forwarded to the gateway of the network B, and the gateway of the network B is forwarded to a host of the network B. The process of forwarding the data packet from the network B to the network a is also the same, so that the TCP/IP protocol can only realize the intercommunication between different networks if the IP address of the gateway is set. Then what is the IP address of which machine? The IP address of the gateway is the IP address of the device having the routing function, and the device having the routing function includes a router, a server (which is substantially equivalent to a router) having a routing protocol enabled, and a proxy server (which is also equivalent to a router).
Three wan interfaces, for example, a first wan interface, a second wan interface, and a third wan interface, may be included in the target system in this embodiment; the target wan interface may be a wan interface specified by the user, for example, the first wan interface, which is not limited in this embodiment.
In an alternative implementation manner of this embodiment, the connection state of each wan interface in the target system may be checked in a polling manner at intervals of a first set time interval, and if the connection state of the target wan interface is the connected state, the target wan interface is determined to be a default gateway.
Optionally, in this embodiment, the connection state of each wan interface in the system may be checked by using a custom ethmon module periodically using ubus polling, and if the wan interface specified by the user is in a connected state, it is set as a default gateway; for example, if the target system includes three interfaces wan, namely, a first wan interface, a second wan interface, and a third wan interface, and the user-specified interface wan is the first wan interface, if it is checked through ubus polling that the connection status of the first wan interface is connected, the first wan interface may be set as a default gateway.
In an optional implementation of this embodiment, determining the target wan interface as a default gateway may include: querying information of a current wan interface, and if the current wan interface is not the target wan interface, querying information of each wan interface; if it is determined that the target wan interface has been successfully dialed, updating the current interface information; wherein the target wan interface is a wan interface specified by a user.
The current wan interface may be a wan interface with successful dialing, which may be the same interface as the target wan interface, or may be another interface, which is not limited in this embodiment.
Optionally, if it is determined that the connection state of the target wan interface is the connected state, the information of the current wan interface may be further queried, if the current wan interface is not the target wan interface specified by the user, the information of all the wan interfaces in the system needs to be queried, if it is found that the wan interface specified by the user has been successfully dialed, the information of the current wan interface may be updated, and the corresponding information of the default gateway, DNS, DHCPV6 PD, and the like may be set; if the current wan interface is the target wan interface designated by the user, only the information of the current wan interface needs to be queried, whether the gateway addresses are the same is judged, and if not, updating is performed.
In an optional implementation of this embodiment, after determining the target wan interface as a default gateway, the method may further include: determining a DNS address corresponding to the target wan interface as a DNS nameserver; the current wan interface name is determined.
Alternatively, in this embodiment, if the target wan interface specified by the user is in the connected state, it is set as the default gateway, and its corresponding DNS address is set as the DNS domain name server, and the current wan interface name is set.
Step 120, determining whether the information of the current wan interface is null.
In an alternative implementation of this embodiment, after determining the target wan interface specified by the user as the default gateway, it may be further determined whether the information of the current wan interface is null; optionally, in this embodiment, determining whether the information of the current wan interface is null may include: determining interface information of a first wan interface which acquires an IP address and/or a gateway address; if the interface information of the first wan interface is different from the interface information of the target wan interface, determining that the information of the current wan interface is null.
In this embodiment, when the other wan interfaces (interfaces other than the target wan interface) acquire information such as an IP address and a gateway address, the mobile gateway information set by the other wan interfaces is covered, that is, the current wan interface information is set to a null value.
And 130, in the case that the information of the current wan interface is null, polling the connection state of each wan interface every second set time interval, and if the connection state of the target wan interface is a disconnection state, adjusting the default gateway to be a reference wan interface.
The second set time interval may be 3 seconds, 5 seconds, 10 seconds, or the like, which is not limited in this embodiment. In this embodiment, the first set time interval is greater than the second set time interval, for example, the first set time interval is 30 seconds, and the second set time interval is 3 seconds.
In an alternative implementation manner of this embodiment, after the current wan interface information is set to a null value, the connection status of each wan interface may be further polled every second set time interval, and if the connection status of the target wan interface is in a disconnected status, the default gateway is adjusted to be the reference wan interface.
In an optional implementation manner of this embodiment, if the connection state of the target wan interface is a disconnected state, the adjusting the default gateway to be the reference wan interface may include: determining the sequence of the wan interfaces, and determining the gateway address and the DNS address acquired by the first wan interface as the default gateway address and the domain name server address; wherein the reference wan interface is the first wan interface.
Optionally, in this embodiment, the information of each wan interface may be polled again by the custom-defined ethmon module, if it is determined that the current wan interface information is null, the connection state of each wan interface may be queried by ubus, and if the connection state of the target wan interface is the disconnection state, the gateway address and the dns address acquired by the first wan interface may be used as default gateway and domain name server addresses according to the wan interface sequence.
In another optional implementation manner of this embodiment, in a case where the information of the current wan interface is null, polling the connection status of each wan interface every second set time interval includes: if the connection state of the target wan interface is the connected state, determining the gateway address and DNS address of the target wan interface as the default gateway address and domain name server address.
Optionally, in this embodiment, the information of each wan interface may be polled again by the custom-defined ethmon module, if it is determined that the current wan interface information is null, the connection state of each wan interface may be queried by ubus, and if the connection state of the target wan interface is the connected state, the designated interface gateway address and dns address may be updated as default gateway and domain name server addresses.
According to the technical scheme, the connection state of each wan interface in the target system is checked through polling at each first set time interval, and if the connection state of the target wan interface is the connected state, the target wan interface is determined to be a default gateway; determining whether the current wan interface information is null; under the condition that the information of the current wan interface is null, the connection state of each wan interface is polled every second set time interval, and if the connection state of the target wan interface is in a disconnection state, the default gateway is adjusted to be the reference wan interface, so that the device can rapidly switch the link path, and normal network communication and surfing experience of a user are not affected.
In order to better understand the gateway adjustment method according to the embodiment of the present invention, a specific description is adopted below, and the specific scheme of the gateway adjustment method according to the embodiment of the present invention is as follows:
1. it can be understood that the module wide-dhcpv6 of the ipv6 needs to be developed to support more than wan, and only a single wan is supported by default to acquire the ipv6 address; in this embodiment, the interface information of wan is transmitted to the wide-dhcpv6 module as a parameter, and wan interface information is analyzed in the wide-dhcpv6 module, so that the device can be compatible with multiple uhcp 6c processes to obtain the ipv6 addresses of multiple interfaces;
2. macro isolation is needed to be used for a function for setting the DNS address in the netifd module, and the DNS address is uniformly configured by the ethmon;
3. a shell script of multi-wan is added in/etc/hotplug.d/ifoce/and when any wan interface obtains an IP address ifup, the information of the current wan interface (comprising ipv4 and ipv 6) is emptied; if the current wan interface ifdown is performed, the current wan interface (including ipv4 and ipv 6) information is also emptied;
4. when wan obtains an ipv6 address, uniformly transmitting the gateway setting the ipv6 and DHCPv6 PD operation to the ethmon for processing;
5. after wan has been numbered, ethmon polls wan the interface status every 30 seconds; if the current wan interface is empty, inquiring wan interface state every 3 seconds, and returning to 30 seconds after dialing is successful;
6. When inquiring wan interface state, if the current wan interface is wan interface appointed by the user, only inquiring the information of the current wan interface, judging whether the gateway addresses are the same, and if not, updating; if the current wan interface is not the wan interface designated by the user, information of all wan interfaces needs to be queried, if the wan interface designated by the user is successfully dialed, the current wan interface information is updated, and corresponding information such as a default gateway, DNS, DHCPV6 PD and the like is set.
By means of the scheme of the embodiment, a single physical wan interface can be used for establishing a plurality of virtual interfaces to dial and obtain the ipv4 and ipv6 addresses, internet service requests are carried out according to wan interfaces designated by users as default routes, meanwhile, connection states of wan interfaces are monitored, if dialing disconnection occurs, default routes of equipment are timely adjusted, and users can continue to normally surfing without perception.
According to the scheme, the default gateway, the dns address information, the DHCPv6 PD and other information are stripped from the netifd, the settings are uniformly put into a custom module for ethmon processing, the states of the connection of the network gateway wan are monitored in a polling mode in the ethmon, if abnormality is found or the connection is inconsistent with an interface designated by a user, correction is timely carried out, and the internet surfing service of the user can be timely switched to a normal wan interface link for surfing.

Steps 340, wan are disconnected.
Step 350, determining whether the currently used wan is disconnected;
If yes, go to step 360.
Step 360, the current wan configuration is set to null.
In this embodiment, a hotplug processing script is added, when wan dials successfully, the configuration of the current wan interface is cleared, and the ethmon is triggered to immediately perform the adaptation update, when wan disconnects, if the disconnected wan connection is the current wan interface, the configuration of the current wan interface is cleared, and the ethmon is triggered to immediately perform the adaptation update.
It can be understood that the specific implementation steps of the gateway adjustment method related to this embodiment are as follows:
s1: when the default wan interface of the web page is modified, the configuration of the current wan interface is cleared, triggering ethmon to immediately make dynamic adjustments.
S2: and adding a processing script of the hotplug, when wan dialing is successful, clearing the configuration of the current wan interface, triggering the ethmon to immediately perform adaptation updating, and when wan is disconnected, if the disconnected wan connection is the current wan interface, clearing the configuration of the current wan interface, and triggering the ethmon to immediately perform adaptation updating.
