Preferably, the master control system may communicate with the container system through a predefined channel. Similarly, the container systems can communicate with each other through the container channel. Wherein the predefined channel may be a socket channel.
The embodiment of the invention provides a method for connecting a multi-system network, wherein the multi-system comprises the following steps: a plurality of container systems and a master control system, wherein only a first container system of the plurality of container systems is connected to a physical network device, as shown in fig. 2, the method includes:
Step 201, when the master control system starts the container systems, a bridge node is created in the master control system, and a corresponding virtual network port is created for each container system.
one end of each virtual network port is arranged in the respective container system, and the other end of each virtual network port is connected with the network bridge node.
for example, the multi-system mobile terminal includes a first container system and a second container system, where only the first container system is connected to the physical network device, the bridge node created by the master control system is br0, the virtual portal created by the master control system for the first container system is veth-pair1, and the virtual portal created for the second container system is veth-pair 2.
Step 202, the other container systems establish communication connection with the virtual network port corresponding to the first container system through their respective corresponding virtual network ports and bridge nodes.
for the embodiment of the present invention, each container system creates a virtual network port corresponding to its respective container system, and the master control system sets a bridge node, so that the virtual network port of its respective container system, the bridge node in the master control system, and the virtual network port of the first container system can establish a communication channel for communication connection.
For example, the virtual gateway path-pair 2 corresponding to the second container system, br0 of the master control system and the virtual gateway path-pair 1 corresponding to the first container system establish communication connection.
Step 203, the other container system performs data transmission with the physical network device based on the communication connection.
For the embodiment of the present invention, because only the first container system in the multi-system mobile terminal is connected to the physical network device, other container systems can perform data transmission with the physical network device through the first container system based on the communication connection.
The embodiment of the invention provides a method for connecting a multi-system network, compared with the method that each container system in a mobile terminal carries out data transmission with a physical network device through respective network hardware, the embodiment of the invention only connects a first container system in the multi-system mobile terminal with the physical network device, and a main control system establishes a virtual network port and a network bridge node corresponding to each container system, so that other container systems establish communication connection with the virtual network port of the first container system according to the virtual network port of the respective container system and the network bridge node in the main control system, namely, only one network hardware can be arranged in the first container system and is connected with the physical network device in the multi-system mobile terminal, the other container systems carry out data transmission with the physical network device through the first container system, and each container system is not required to be provided with a hardware device, independently carry out data transmission with physical network equipment, thereby can reduce cost, and when a plurality of container system need carry out network data transmission simultaneously, only need operate a network hardware, power consumption has been reduced, promote user experience, and other container systems in the mobile terminal all can be through the network hardware that first container system corresponds, carry out data transmission with physical network equipment, promptly simultaneously, every container system in the mobile terminal all can carry out data transmission through network hardware, thereby every container system in the mobile terminal all can carry out data transmission simultaneously.
Another possible implementation manner of the embodiment of the present invention is, on the basis as shown in fig. 2, in step 201, when the master control system starts the container systems, a bridge node is created in the master control system, and a corresponding virtual network port is created for each container system, and then step 301 shown in fig. 3 is further included.
step 301, the master control system configures the IP addresses in the network addresses respectively corresponding to each virtual network port and each bridge node into the same lan segment.
For the embodiment of the invention, the network address comprises: media Access Control (MAC) address and Internet Protocol (IP) address, which means that the IP addresses of each virtual network port and each bridge node are in the same lan segment.
For example, the IP address corresponding to the virtual portal of the first container system in the multi-system mobile terminal is configured to be 172.29.52.60/24, the IP address corresponding to the bridge node in the main control system is configured to be 172.29.52.50/24, and the IP address corresponding to the virtual portal of the second container system is 172.29.52.70/24, so that the IP address corresponding to the virtual portal of the first container system, the IP address corresponding to the bridge node, and the network address corresponding to the virtual portal of the second container system are all located in the same virtual network subnet segment 172.29.52.0/24.
For the embodiment of the invention, the main control system configures the network addresses respectively corresponding to the virtual network ports and the network bridge nodes into the same local area network segment, so that the virtual network ports and the network bridge nodes can be directly addressed with each other, the network addresses corresponding to the next-hop virtual network ports or the network bridge nodes are determined, and data transmission is performed, thereby reducing the addressing complexity and further improving the feasibility of multi-system network connection.
In another possible implementation manner of the embodiment of the present invention, on the basis of the step shown in fig. 3, the step 203, where the other container system performs data transmission with the physical network device based on the communication connection, includes a step 401 shown in fig. 4.
step 401, the other container systems perform data transmission with the physical network device by invoking a packet forwarding service of the first container system based on the communication connection.
For the embodiment of the present invention, when the master control system starts the container system, the first container system opens the packet forwarding service function, which provides a guarantee for the first container system to forward the received data packets sent by other container systems to the physical network device, or forward the received data packets sent by the physical network device to other container systems.
For the embodiment of the present invention, by calling the packet forwarding service of the other container system, the other container system can forward the data packet from the first container system to the physical network device through the communication connection, so that the network device can be set in the first container system only to perform data transmission with the physical network device, and further the manufacturing cost of the mobile terminal can be reduced.
In another possible implementation manner of the embodiment of the present invention, on the basis as shown in fig. 4, step 401, the other container systems perform data transmission with the physical network device by invoking a packet forwarding service of the first container system based on the communication connection, including steps 501 to 504 as shown in fig. 5.
Step 501, the other container systems send the network access request message to the first container system through their respective corresponding virtual network ports, bridge nodes, and virtual network ports corresponding to the first container system.
the network access request message carries the network address of the virtual network port corresponding to the container system of the request sender. Wherein, the network address includes: a media access control MAC address, an internet protocol IP address, and port information of the request sender container system.
In the embodiment of the present invention, the port information carried in the network access request message is used to characterize the server of the network data required to be requested corresponding to the port of each request-sending container system.
For example, when a user executes an operation of opening a search fox webpage through the second container system, a network access request message for acquiring the search fox webpage is generated, and port information carried in the network access request message is port information of a port 1; when a user requests to play the love art video through the second container system, a network access request message for acquiring the video is generated, and the port information carried in the network access request message is the port information of the port 2.
For the embodiment of the present invention, when other container systems in the mobile terminal need to perform network connection with the physical network device, the container system sends a network access request message carrying the network address of the virtual network port in the container system to the first container system through the virtual network port of the container system, the network bridge node, and the virtual network port of the first container system.
step 502, the first container system changes the IP address of the virtual network port corresponding to the container system of the request sending party carried in the network access request message into the IP address of the physical network card of the mobile terminal, and/or changes the port information of the container system of the request sending party into the port information of the first container system, and records the network address change information.
The port number of the first container system for sending the network access request message may be the same as or different from the port number of the first container system for requesting the sender to send the network access request message. The present invention is not limited to the embodiments.
for the embodiment of the present invention, the network address change information includes: the IP address of the virtual network port corresponding to the container system of the request sending party, the port information of the container system of the request sending party and the port information of the first container system.
For the embodiment of the present invention, in the process that the other container system sends the network access request message to the physical network device through the virtual network port corresponding to the container system of the other container system, the network bridge node, the virtual network port corresponding to the first container system, and the physical network card, the IP address of the source network address is changed from the IP address of the virtual network port corresponding to the container system of the sender requesting party to the IP address of the physical network card of the mobile terminal, and the port number corresponding to the first container system is changed from the port number corresponding to the container system of the sender requesting party to the port information.
for example, a mobile terminal of multiple systems includes a first container system and a second container system, where the first container system is in network connection with a physical network device, an IP address of a virtual network port corresponding to the second container system is 172.29.52.70/24, a port number of a network access request message sent by the second container system is 56, an IP address of a virtual network port corresponding to the first container system is 172.29.52.60/24, a port number of the network access request message sent by the first container system is 80, an IP address corresponding to a bridge node in the master control system is 172.29.52.50/24, and an IP address of a physical network card of the mobile terminal is 172.29.52.60/25, and then after receiving the network access request message sent by the second container system, the first container system changes the IP address carried in the network access request message from 172.29.52.70/24 to 172.29.52.60/25, and changes the carried port information from 56 to 80.
for the embodiment of the present invention, because the network address carried in the network access request message received by the first container system is the network address corresponding to the virtual network port of the container system of the sender, and if the first container system sends the network request message carrying the network address to the physical network device, the destination IP address in the data packet sent to the mobile terminal by the physical network device is the IP address of the virtual network port corresponding to the other container system, so that the mobile terminal cannot receive the data packet returned by the physical network device, thereby causing the network transmission to be interrupted. In the embodiment of the invention, the first container system changes the IP address carried in the network access request message into the IP address corresponding to the physical network card of the mobile terminal, so that the physical network device addresses according to the physical network card of the mobile terminal and returns the data packet to the mobile terminal, thereby avoiding the condition that the physical network device cannot address and further avoiding the interruption of data transmission.
step 503, the first container system acquires the routing information.
The routing information is the network address of the next hop physical network device corresponding to the network access request message after the first container system sends the network address to be changed.
for the embodiment of the present invention, the first container system may obtain the routing information from the generated routing table, and determine the network address of the next hop physical network device corresponding to the network access request message received by the first container system.
step 504, the first container system sends the network access request message after the network address is changed to the physical network device according to the routing information.
For the embodiment of the invention, the first container device sends the network access request message after changing the network address to the next-hop physical network device according to the routing information, and according to the steps, the network access request message after changing the network address is sent to the final physical network device for network connection.
for example, the first container system sends the network access request message with the network address changed to the next-hop router device, and sends the network access request message with the network address changed to the base station through the plurality of router devices.

Step 601, when the first container system receives a data packet sent by a physical network device, the first container system detects whether network address change information exists.
for the embodiment of the present invention, if the network address change information does not exist in the first container system, the first container system parses and processes the data packet, and does not forward the data packet to other container systems.
Step 602, if there is network address change information, the first container system searches the IP address of the virtual network port corresponding to the container system of the request sender and the port information of the container system of the request sender from the network address change information according to the port information of the first container system carried in the data packet.

Then, the first container system determines the MAC address of the IP address of the virtual network port corresponding to the container system of the request sender from the routing table, and changes the destination MAC address in the data packet into the determined MAC address of the virtual network port corresponding to the container system of the request sender.
Step 603, the first container system sends the data packet to the corresponding container system based on the communication connection according to the IP address of the virtual network port corresponding to the container system of the request sender and the port information of the container system of the request sender.
For the embodiment of the present invention, the first container system determines, according to the IP address before the change in the network address change information, a target container system to which the data packet actually requests forwarding, and sends the data packet received from the physical network device to the target container system through the virtual network port corresponding to the first container system, the network bridge node, and the virtual network port corresponding to the container system that actually performs the network connection request.
For the embodiment of the present invention, the data packet also carries port information for sending a network request message, and after receiving the data packet, the target container system sends the data packet to a corresponding port according to the port information carried in the data packet.
