Example one
Fig. 1 is a flowchart of a gateway adjusting method according to an embodiment of the present invention, where this embodiment is applicable to a case of performing fast adjustment on a default gateway, and the method may be executed by a gateway adjusting apparatus, where the gateway adjusting apparatus may be implemented in a form of hardware and/or software, and the gateway adjusting apparatus 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 at intervals of a first set time interval, and if the connection state of a target wan interface is a connected state, determining the target wan interface as a default gateway.
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 another embedded Linux system, which is also 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 the gateway. In a TCP/IP network system, a gateway basically functions to select an optimal outlet to forward an IP packet according to a network number and a subnet number of a destination IP address, thereby realizing data communication across network segments. Sometimes, a gateway is also considered to be the IP address with a data forwarding device, and the IP address of the gateway and its subnet should be on the same network segment. For example, there are network a and network B, the IP address range of network a is "192.168.1.1-192.168.1.254", the subnet mask is 255.255.255.0; the IP address range of the network B is 192.168.2.1-192.168.2.254, and the subnet mask is 255.255.255.0. Without a router, TCP/IP communication between two networks is not possible, and even if two networks are connected to the same switch (or hub), the TCP/IP protocol determines that the hosts in the two networks are in different networks based on the subnet mask (255.255.255.0). Communication between the two networks must be accomplished through a gateway. If the host in network A finds that the destination host of the data packet is not in the local network, the data packet is forwarded to the gateway of the host in network A and then forwarded to the gateway of network B, and the gateway of network B forwards to a host in network B. The same is true for the process of forwarding the data packet from the network B to the network a, so that the TCP/IP protocol can only realize the intercommunication between different networks if the IP address of the gateway is set. Then is this IP address of which machine? The IP address of the gateway is an IP address of a device having a routing function, and the device having a routing function includes a router, a server (substantially equivalent to one router) that enables a routing protocol, and a proxy server (also equivalent to one router).
In the present embodiment, the target system may include three wan interfaces, for example, a first wan interface, a second wan interface, and a third wan interface; the target wan interface may be a wan interface specified by a user, for example, the first wan interface, which is not limited in this embodiment.
In an optional implementation manner of this embodiment, the connection state of each wan interface in the target system may be polled and checked every first set time interval, and if the connection state of the target wan interface is a connected state, the target wan interface is determined as a default gateway.
Optionally, in this embodiment, the connection state of each wan interface in the system may be periodically checked by using a customized ethmon module, and if the wan interface specified by the user is in a connected state, the connection state is set as a default gateway; illustratively, if the target system includes three wan interfaces, namely a first wan interface, a second wan interface and a third wan interface, and the wan interface specified by the user is a first wan interface, if the first wan interface is detected to be connected through ubus polling, the first wan interface may be set as the default gateway.
In an optional implementation manner of this embodiment, determining the target wan interface as a default gateway may include: inquiring information of a current wan interface, and if the current wan interface is determined not to be the target wan interface, inquiring information of each wan interface; if the target wan interface is determined to be dialed successfully, updating the current interface information; wherein, the target wan interface is a wan interface designated by a user.

In an optional implementation manner of this embodiment, after determining that the target wan interface is the default gateway, the method may further include: determining a DNS address corresponding to the target wan interface as a DNS domain name server; the current wan interface name is determined.
Optionally, in this embodiment, if the target wan interface specified by the user is in a connected state, it is set as a default gateway, and sets the DNS address corresponding to the default gateway as the DNS nameserver, and sets the current wan interface name.
And step 120, determining whether the information of the current wan interface is a null value.
In an optional implementation manner of this embodiment, after determining that the target wan interface specified by the user is 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 a null value may include: determining interface information of a first wan interface for acquiring an IP address and/or a gateway address; and 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 a null value.
It should be noted that, in this embodiment, when another wan interface (an interface other than the target wan interface) acquires information such as an IP address and a gateway address, the moving gateway information set by the interface is overwritten, that is, the information of the current wan interface is set to a null value.
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 optional implementation manner of this embodiment, after the current wan interface information is set to be null, the connection state of each wan interface may be further polled at second set time intervals, and if the connection state of the target wan interface is a disconnected state, the default gateway is adjusted to refer to wan interface.
In an optional implementation manner of this embodiment, if the connection state of the target wan interface is a disconnection state, adjusting the default gateway to the reference wan interface may include: determining the sequence of wan interfaces, and determining a gateway address and a DNS address acquired by a 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 through a customized ethmon module, if it is determined that the current wan interface information is null, the connection state of each wan interface may be queried through the ubus, and if the connection state of the target wan interface is a disconnection state, the gateway address and the dns address obtained by the first wan interface may be used as the default gateway and domain name server address according to the wan interface sequence.
In another optional implementation manner of this embodiment, when the information of the current wan interface is null, polling the connection state of each wan interface at intervals of a second set time interval includes: and if the connection state of the target wan interface is the connected state, determining the gateway address and the DNS address of the target wan interface as the default gateway address and the domain name server address.

According to the technical scheme of the embodiment, the connection state of each wan interface in the target system is polled and checked at every interval of a first set time interval, and if the connection state of a target wan interface is a connected state, the target wan interface is determined as a default gateway; determining whether the information of the current wan interface is null; when the information of the current wan interface is null, polling the connection state of each wan interface at every second set time interval, and if the connection state of the target wan interface is a disconnection state, adjusting the default gateway to refer to wan interface, so that the device can quickly switch the link path without affecting the normal network communication and internet experience of the user.
In order to better understand the gateway adjusting method involved in the embodiment of the present invention, the following is to specifically describe the gateway adjusting method, and a specific scheme of the gateway adjusting method involved in the embodiment is as follows:
1. it can be understood that the module wide-dhcpv6 required to develop ipv6 supports wan, and only supports wan to obtain ipv6 address by default; in the embodiment, the interface information of wan is used as parameters and transmitted to the wide-dhcpv6 module, and the wan interface information is analyzed in the wide-dhcpv6 module, so that the ipv6 address of a plurality of interfaces can be obtained by being compatible with a plurality of udhcp6c processes;
2. macro isolation is used for a function for setting a DNS address in a netifd module, and a DNS address is uniformly configured by ethmon;
3. adding a shell script of multi _ wan in/etc/hot plug.d/iface/and emptying information of a current wan interface (including ipv4 and ipv 6) when an arbitrary wan interface acquires an IP address ifup; if the current wan interface is ifdown, the information of the current wan interface (including ipv4 and ipv 6) is also cleared;
4. when wan obtains the ipv6 address, uniformly handing gateway and DHCPv6 PD operations for setting ipv6 to ethmon for processing;
5. after wan has dialed up, ethmon polls wan interface state every 30 seconds; if the current wan interface is empty, inquiring the wan interface state every 3 seconds, and returning the polling time to 30 seconds after dialing is successful;
6. when the wan interface state is inquired, if the current wan interface is the wan interface appointed by the user, only the information of the current wan interface needs to be inquired, whether the gateway addresses are the same or not is judged, and if the gateway addresses are different, updating is carried out; if the current wan interface is not wan interface designated by the user, the information of all wan interfaces needs to be inquired, and if the wan interface designated by the user is found to be dialed successfully, the information of the current wan interface is updated, and the corresponding information of the default gateway, DNS, DHCPV6 PD and the like is set.
By the scheme of the embodiment, a single physical wan interface can establish a plurality of virtual interfaces to dial to acquire ipv4 and ipv6 addresses, an internet service request is performed by taking a wan interface designated by a user as a default route, the connection state of the wan interface is monitored, if the dial-up is disconnected, the default route of the device is adjusted in time, and the user can continue to surf the internet without sensing.
According to the scheme of the embodiment, the settings of information such as a default gateway, dns address information, DHCPv6 PD and the like are stripped from the netifd and are put into a custom module ethmon for processing in a unified manner, the state of multi-wan connection is polled and monitored in the ethmon, if abnormity is found or the connection state is inconsistent with an interface designated by a user, correction is carried out in time, and the purpose that the internet access service of the user can be switched to a normal wan interface link for internet access is achieved in time.

It can be understood that the gateway adjusting method related in this embodiment is implemented as follows:
s1: when the default wan interface of the web page is modified, the configuration of the current wan interface is cleared, and ethmon is triggered to immediately make dynamic adjustment.
S2: adding a processing script of a hot plug, emptying the configuration of a current wan interface when wan dials successfully, triggering ethmon to immediately do adaptation updating, and emptying the configuration of the current wan interface to immediately do adaptation updating if the disconnected wan connection is the current wan interface when wan is disconnected.
S3: when the dynamic address and the static address of the DNS address are switched on the web page, a DNS modification flag is set, ethmon is triggered to detect that the DNS address is modified, the DNS address and the DHCPv6 PD are immediately updated, and a hung client such as a PC or a mobile phone is informed to update the DNS address.
S4: the ethmon module polls and checks the interface state of wan, and checks every 3 seconds;
s5: if the wan interface is not connected with the network cable, the process returns to S4, and if the wan interface is connected, the process proceeds to S6.
S6: if wan fails to dial, or the current wan is configured to be empty, entering S8;
