As another example, the terminal device 200 and other devices share the network via bluetooth through a bluetooth connection.
Fig. 6 is a schematic flow chart of network sharing according to an embodiment of the present application. Network sharing is performed for the terminal device 200 that already has a network connection. First, the user enters the setting interface by clicking on the "setting" option provided by the terminal device 200, and opens the network sharing by clicking on the "network sharing" option, and starts the network sharing service of the terminal device 200, i.e., the IP Server, allowing other devices to connect and use the shared network connection. And (5) reconfiguring and starting a dynamic host configuration protocol Server (Dynamic Host Configuration Protocol, DHCP Server), wherein the DHCP Server is a Server for distributing IP addresses and other network configuration information, when the DHCP Server is configured, the IP addresses and the subnet masks of the DHCP Server are set, and the DHCP Server is configured and started, so that other devices can acquire the required information such as the IP addresses, the subnet masks and the like through the DHCP Server.

An IP forwarding Service and a domain name Service (Domain Name Service) are reconfigured and started, wherein IP forwarding refers to a function of forwarding a data packet from one network interface to another network interface in a shared network, and by configuring and starting the IP forwarding Service, data in the shared network can be forwarded correctly. And finally, configuring the ip rule and the ip tables, wherein the ip rule and the ip tables are tools for setting network rules and configuring firewalls, and the rules of the ip rule and the ip tables can be configured according to actual requirements so as to realize control and security of network traffic.
Based on the above network sharing method, for the terminal device 200 having a network connection, other devices may be connected to the shared network of the terminal device 200 in a wireless or wired manner to obtain rights to access the internet. However, when implementing network sharing, the user is required to connect the terminal device 200 to the local network first, and then check whether the device requiring network sharing is available after the connection is successful, and then perform network sharing if available. That is, the terminal device 200 may be interconnected with other devices and share the network after accessing the internet. This way of requiring uplink network connection before sharing limits the use scenarios of network sharing. For example, the user may just set up a path when sharing the network, that is, the terminal device 200 may be connected to other devices without an uplink network connection.
In order to solve the problem of limited network sharing use, some embodiments of the present application further provide a wired network sharing method, which is applied to the terminal device 200, and after the terminal device 200 is powered on, the wired network sharing can be automatically performed, a channel for network sharing between the terminal device 200 and the external device is established, and uplink network changes are monitored, so as to implement network use of the external device. Wherein the terminal device 200 capable of applying the wired network sharing method includes: network portal and controller 250. The network port is configured to establish a connection with an external device, and the controller 250 is configured to execute the wired network sharing method.

The terminal device 200 may connect to an Upstream Network (upflow Network) to achieve Network access. An Upstream Network (Upstream Network) refers to a direction in which data flows from a local Network to other Network nodes or a higher-level Network, and may refer to an electronic device such as a switch, a router, etc. connected to the local Network, and is responsible for transferring data to the other Network nodes or the higher-level Network. The uplink network includes a wired network and a wireless network, that is, the terminal device 200 may connect the networks in a wired connection network manner or a wireless connection network manner.
To connect to the network and to share the network, the terminal device 200 includes two network ports, an eth1 port and an eth0 port, respectively. The terminal device 200 may be connected to an electronic device that provides a network, such as a router, through an eth0 network port, and may also be connected to WiFi that is provided by an electronic device, such as a router, in a wireless manner, so as to implement connection to an uplink network. The eth1 network port is used for establishing a connection relationship with the external device, one end of the network cable can be connected through the eth1 network port, and the other end of the network cable can be connected with the external device at the same time, so that the wired connection between the terminal device 200 and the external device is realized.
The external device refers to a device of a shared network, and may be, for example, an open pluggable specification (Open Pluggable Specification, OPS) computer, a smart television, a laser projection device, a monitor (monitor), an electronic whiteboard (electronic bulletin board), and the like.
After the network cable of the external device is inserted into the eth1 network port, the terminal device 200 can be interconnected with the external device, a channel shared by the terminal device 200 and the external device network is established through the eth1 network port, and after the terminal device 200 is connected with the uplink network, the external device connected with the eth1 network port shares the network, so that the networking of the external device is realized. That is, after the external device is connected to the terminal device 200 through the eth1 network port in a wired manner, the external device can be connected to the terminal device 200, and there is no requirement for an uplink network of the terminal device 200, and the external device may be connected to the uplink network or not connected to the uplink network. And after the terminal equipment 200 is connected to the uplink network, the terminal equipment 200 can share the network with the external equipment, and the limitation that the uplink network is required to be connected first and then shared when the network is shared is broken.
It is to be understood that the number of eth1 ports is not limited to the number shown in fig. 7, and the terminal device 200 may determine the number of devices that the terminal device 200 can share the network according to the number of eth1 ports. And if the number of the eth1 network ports is 1, the number of the external devices corresponding to the shared network is 1. The number of the eth1 network ports is multiple, and the number of the external devices corresponding to the shared network is multiple.
As shown in fig. 8, fig. 8 is a flow chart of a wired network sharing method in an embodiment of the present application, which specifically includes the following contents:
s100: and responding to a starting event of the terminal equipment, and monitoring the node state of the network port.
The controller 250 of the terminal device 200 may receive various control instructions input by a user during use by the user, thereby controlling the overall operation of the display device 200. Wherein, different control instructions correspondingly have different functions. For example, the user may click on a "setup" option provided by the terminal device 200, invoking a setup interface. The setting interface comprises a network sharing option, and the user can click on the network sharing option to enter the network sharing interface shown in fig. 9. The network sharing interface includes network sharing modes such as bluetooth network sharing, USB network sharing, wired network sharing, etc., and the user can click on the corresponding option to control the terminal device 200 to execute network sharing based on the corresponding network sharing mode. The user clicks the "wired sharing network" option, and an instruction for performing wired network sharing may be input to the controller 250, and the controller 250 may control the terminal device 200 to perform the wired network sharing method provided in the embodiment of the present application in response to the instruction.
In order to reduce the user operation steps, the method for sharing the wired network provided in the present application may be automatically triggered and executed after the terminal device 200 is powered on, that is, after the terminal device 200 performs the power on operation, a power on event is triggered, and in response to the power on event, the controller 250 may control the terminal device 200 to execute the method for sharing the wired network. That is, the wired network sharing method provided in the embodiment of the present application does not need the user to click the switch of the "network sharing" option from the setting page or other application entries, nor does it need the connection triggering of the uplink network, and the wired network sharing can be automatically performed after the terminal device 200 is powered on.
The wired network sharing method provided in the embodiment of the present application may establish a channel for sharing a network between the terminal device 200 and an external device after the terminal device 200 is connected to the external device through a network port in a wired manner, and share the network with the external device after the terminal device 200 is connected to an uplink network. Accordingly, the controller 250 may monitor the node status of the network port, i.e., whether the devices of the shared network and the terminal device 200 are hardware-connected, in response to the power-on event of the terminal device 200.
The node state includes a connected state and an unconnected state, and it can be understood that the connected state refers to a state that the external device is inserted into the network port through the network cable and the data transmission of the network cable is normal, and the unconnected state refers to a state that the network cable is not inserted into the network port or the data transmission of the network cable is abnormal. And when the node state is monitored to be in a connected state, establishing a channel shared by the terminal equipment 200 and an external equipment network.
In some embodiments, the controller 250 may initiate a network service, such as an Ethernet service (Ethernet service), in response to a power-on event of the terminal device 200, and register a monitoring procedure for a node status of the network port to monitor the node status of the network port, and update the node status to a connected status (i.e., up status) when it is monitored that there is a network signal transmission in the network port. That is, after the terminal device 200 is powered on, it may traverse the loaded network port, detect whether the data path of the loaded network port is a path, that is, whether the network port is inserted into a network cable and whether there is network signal transmission, and if the data path of the network port is a path, update the node state of the network port to be a connected state.
Taking the use scenario shown in fig. 7 as an example, the terminal device 200 may share a network with an external device connected to the eth1 portal. After the terminal device 200 is powered on, the controller 250 may monitor whether the external device is connected to the terminal device 200 in hardware, that is, whether the eth1 port is in a connected state (i.e. up state), and when it is monitored that the node state of the eth1 port is in the connected state, establish a channel shared by the terminal device 200 connected to the eth1 port and the external device network.
S200: and when the node state is a connected state, setting a network port mode of the network port as a server mode.
Before establishing a channel shared by the terminal device 200 and the external device network, a sharing mode of the network port needs to be distinguished. The sharing mode includes a client mode (client mode) and a server mode (server mode). The client mode is used for representing the network port as an entry of network sharing of the terminal device 200, and the server mode is used for representing the network port as an exit of network sharing of the terminal device 200. It may be understood that if the network port is used as an entry for network sharing of the terminal device 200, the external device connected to the network port shares the network with the terminal device 200, and if the network port is used as an exit for network sharing of the terminal device 200, the terminal device 200 shares the network with the external device connected to the network port.
Taking the use scenario shown in fig. 7 as an example, the eth0 portal is used as a client mode, and is used as a portal for network sharing of the terminal device 200, that is, whether the terminal device 200 can monitor whether the network cable of the electronic device providing the network through the eth0 portal is inserted into the terminal device 200, if so, the terminal device 200 can connect to the network through the eth0 portal and surfing the internet. The eth1 network port is in a server mode, and serves as an outlet for network sharing of the terminal device 200, that is, the terminal device 200 can monitor whether a network cable of an external device needing to be shared with the network is inserted into the terminal device 200 through the eth1 network port, if yes, the terminal device 200 can share the network with the external device through the eth1 network port.
Therefore, in order to reduce the situation that the network sharing is opposite, before the controller 250 performs the network sharing through the wired medium, the filtering action of connecting the network is performed with respect to the network port, that is, when the node state of the network port is monitored to be in the connected state, the port mode of the network port is set to be the server mode. That is, the selection judgment is made on the sharing mode of the network sharing, and if the node state of the network port is in the connected state, the network connection operation as the client is not initiated, but is processed as the service (server) side.
In some embodiments, the processing of the wired network by the terminal device 200 may determine the sharing mode according to the name of the wired node. For example, the default of the network port name prefix of "eth" is the client mode, and whether the network cable of the router is inserted into the terminal device 200 is monitored through the network port, if yes, the terminal device 200 can connect to the network through the network port and surfing the internet.
Therefore, the network port may be written and defined in the hardware layer of the terminal device 200 in advance, and when the filtering action of connecting the network is performed with respect to the network port, the controller 250 may read the port name of the network port when the node state of the network port is monitored to be the connected state, where the port name is the port name written in the hardware layer of the terminal device in advance. If the network port name is a first preset name, setting the network port mode of the network port as a server mode so as to share the network with the external equipment connected with the network port. If the network port name is a second preset name, setting the network port mode of the network port as a client mode so as to connect the network based on the network port.
Taking the usage scenario shown in fig. 7 as an example, the terminal device 200 includes two network ports, namely, an eth1 port and an eth0 port. According to the purpose of the network port, the network port names defining the eth1 network port and the eth0 network port are written in the hardware layer in advance, and are respectively 'eth 1' and 'eth 0'. That is, the network port with the network port name "eth1" is used for the shared network, and the network port with the network port name "eth0" is used for the connection network.
As shown in fig. 10, a flow chart of setting a sharing mode of a network port according to an embodiment of the present application is provided, and in response to a power-on event of the terminal device 200, the controller 250 starts an Ethernet service (Ethernet service), and registers monitoring of node states of the network ports (eth 1 port and eth0 port). When the network port is inserted into the network cable and network signals are transmitted, the node state of the network port is updated to be in a connected state.
And when the node state of the network port is in a connected state, selecting and judging a sharing mode of network sharing, and reading the port name of the network port written in the hardware layer in advance. If the network port name is "eth1", it is determined that the network port is an eth1 network port, and the network port MODE of the network port is set as a SERVER MODE (i.e. executing the INTERFACE-MODE-SERVER), and the system of the terminal device 200 is notified that the network port can perform network sharing, so as to share the network with the external device connected to the network port. Correspondingly, if the network port name is "eth0", determining that the network port is an eth0 network port, setting the network port MODE of the network port as a CLIENT MODE (i.e. executing the INTERFACE-MODE-CLIENT), connecting the network through the network port and surfing the internet.
In addition, the sharing mode of the network port can be defaulted to be a client mode (client mode), when the sharing mode of the network sharing is selected and judged, when the network port is detected to be the eth1 port, the sharing mode of the network port is changed to be a server mode (server mode), and if the network port is detected not to be the eth1 port, the processing is not performed, and the sharing mode of the network port is defaulted to be the client mode (client mode).
S300: setting network sharing parameters for external devices connected with the network ports, and sharing a network to the external devices based on the network sharing parameters.
After the network port mode of the network port is the server mode, that is, the network port is selected as the outlet of the network sharing, the controller 250 may set a network sharing parameter for the external device connected to the network port, and share the network to the external device based on the network sharing parameter. This section needs to declare the wired node-to-sharing type conversion section in the terminal device 200, that is, when it is detected that the node state of the network port is the connected state, the controller 250 may set the network sharing type to the wired network sharing type, which is a network sharing type that performs network sharing based on the network port added in advance in the frame layer of the terminal device 200, and share the network to the external device according to the network sharing type.
It will be appreciated that since the native logic of the end device 200 does not assert the wired type by default, only the wired, bluetooth, p2p, etc. nodes are identified, such that the wired node is defined as an invalid shared type (i.e., TETHERING _inv ALID) when it is imported. The embodiment of the application can add the network sharing type (TETHERING _ethernet) for performing network sharing based on the network port in the frame layer (frame) of the terminal device 200, so as to avoid the situation that the network fails due to type invalidation when the network is shared by wire.
In some embodiments, the controller 250 may initiate a network sharing service, i.e., an IP Server, when setting network sharing parameters for an external device connected to the network portal. The network sharing service is based on the allocation of an internet protocol address (i.e. an IP address) to a network port, and the DHCP Server can be enabled to allocate an IP address to a device connected to the sharing network, so as to ensure that the device is started and configured correctly. After the IP address is allocated, the routing parameters and the packet filtering parameters are configured for the external equipment connected with the network port of the network, so that a channel shared by the terminal equipment 200 and the external equipment network is established, namely, the routing, the IP rule and the IP tables are configured, and the data traffic is ensured to be forwarded correctly. In this case, the terminal device 200 does not require an uplink network, and may be connected to the uplink network or may not be connected to the uplink network.
After establishing a channel in which the terminal device 200 shares with the external device network, if the terminal device 200 is not connected to the uplink network, the network cannot be shared with the external device. After the terminal device 200 is connected to the uplink network, the configuration of the uplink network can be changed according to the uplink network connected with the terminal device 200 to configure the data packet forwarding address of the external device, so as to establish a data forwarding path between the external device and the uplink network, thereby realizing the purpose that the terminal device 200 shares the network with the external device, and enabling the external device to access the internet.
When the configuration of the uplink network is changed, the controller 250 may acquire the internet protocol address of the uplink network, and set the packet forwarding address of the external device to the internet protocol address, that is, set the packet forwarding of the domain name Service (Domain Name Service). For example, taking the use scenario shown in fig. 7 as an example, a data forwarding path between the external device and the uplink network is established, so that the data packet can be forwarded from the eth1 port to the eth0 port or the wlan. If the IP address of wifi connected to the terminal device 200 is 162.168.1.1, the DNSForward of the external device is set to 162.168.1.1, so that the data packet can be forwarded from the eth1 network port to the wlan, and internet access of the external device is achieved.
In this embodiment, in the wired network sharing method provided by the present application, when the terminal device 200 is not connected to the uplink network, a channel shared by the terminal device 200 and the external device network may be established, so as to implement interconnection between the terminal device 200 and the external device. After the terminal device 200 is connected to the uplink network, a data forwarding path between the external device and the uplink network is established by changing the configuration of the uplink network, so as to realize the network use of the external device.
In some embodiments, in order to timely acquire the network connection state of the terminal device 200, efficiency of network sharing is improved. The controller 250 may monitor the network connection state of the terminal device 200 and the uplink network, and configure the packet forwarding address of the external device according to the uplink network when the network connection state is monitored to be the connection state, so as to share the network to the external device based on the packet forwarding address.
Exemplary, as shown in fig. 11, a flow chart of wired network sharing is provided in an embodiment of the present application. Taking the use scenario shown in fig. 7 as an example, in response to a power-on event of the terminal device 200, the controller 250 monitors a node state of a network port, and when it is monitored that the node state of the eth1 port is a connected state, shields a client process on the eth1 port, that is, sets a port mode of the eth1 port as a server mode, and uses the eth1 port as an outlet of network sharing. Then, a teaming function in the terminal device 200 is started, and the teaming function refers to the use of sharing internet connection to other devices through a network (such as a 4G network) of the terminal device 200. And starting the IP Server, distributing an IP address for a network port based on the IP Server, performing route configuration, and establishing a channel for network sharing of the terminal equipment 200 and the external equipment.
Meanwhile, the controller 250 registers monitoring on the uplink network, monitors the network connection state of the terminal device 200, i.e. whether wired connection is performed between the terminal device and the electronic device providing the network such as the router through the eth0 network port, or whether wireless connection is performed between the terminal device and the WiFi provided by the electronic device such as the router. If the network connection state is monitored to be the connection state, the configuration of the uplink network can be changed, so that a data forwarding path between the external device and the uplink network is established, and network sharing is performed, so that the purpose of accessing the internet by the external device is achieved.
In some embodiments, the configuration of the upstream network may be altered by listening for network changes through a state machine. That is, the controller 250 may create a State Machine (State Machine) based on which the network connection State of the terminal device with the upstream network is monitored. That is, a state machine is created for handling network change events and state transitions.
The state machine is a model representing different states and transition conditions, and different states may be defined in the state machine, which characterizes the network connection state of the terminal device 200, for example, "Connected" and "Disconnected" are defined, which characterize the network connection state as a Connected state and a Disconnected state, respectively. While state transition conditions and transition actions are defined in the state machine. For example, when the network connection state is changed from "Disconnected" to "Connected", a corresponding event is triggered, and a series of operations are performed to change the configuration of the upstream network.
Specifically, after the terminal device 200 is connected to the UPSTREAM network, the controller 250 receives a broadcast message (e.g. Connectivity-action) sent by the frame layer of the terminal device 200 and indicating that the network connection is successful, triggers an operation of processing a change in the state of the network connection (i.e. handleconnectityaction), and processes a command for changing the UPSTREAM network (i.e. CMD-UPSTREAM-CHANGED). The TetherModeAliverState state machine processes the network change event and sets up the upstream network (i.e., setDNSF orward).

Executing a CMD-te-connect-CHANGED command to handle changes in the network shared connection. Executing a chooseUpstreamType event to select an upstream network type.
And when a callback for wired network sharing is triggered, the type of ipsving is set to TETHERING-ETHERNET (wired network sharing type added in advance at the framework layer). Start IPServer and set ip of DHCP Server to 192.168.44.1. And executing the changeInterfacestate operation for changing the state of the network port. The CMD-TETHER-REQUESTED event is processed for processing the enable network sharing. When the TetherModeAlyState state machine is triggered to process the network change event, the state machine of the IPServer is switched to the TetherdState. The state of the shared network refers to a state when the ipsec is successfully started and is in the shared network state in the network sharing process.
