Before the embodiments of the present application are specifically introduced, some nouns in the embodiments of the present application are simply named. In the embodiment of the present application, the external network interface corresponds to each interface that implements access to the external network by each operating system in the communication device. Similarly, the intranet interface corresponds to each interface that implements internal communication between operating systems in the communication device.

FIG. 1 is a schematic diagram of a framework of a first embodiment of a communication device according to an embodiment of the present disclosure. As shown in FIG. 1 , the communication device includes:

N operating system motherboards, a first switch chip, a first external network interface for connecting to an external wired network, and a switch connected between the first switch chip and the first external network interface, N being an integer greater than or equal to 2.

The N operating system motherboards are respectively provided with a second external network interface connected to the first switch chip; the first operating system motherboard of the N operating system motherboards is connected to the first external network interface, and is connected to the switch.

Based on this, the first operating system carried on the first operating system motherboard is configured to: if the first external network interface is connected to the external wired network, the control switch is turned on.

Illustrated in FIG. 1 is a case where N=2. At this time, the communication device includes a first operating system motherboard carrying the first operating system and a second operating system carrying the second operating system as shown in FIG. Operating system motherboard.

In an actual application, the first external network interface is an interface connected to the network cable, and is generally disposed on a surface of the communication device. For example, when the communication device is a PC, the first external network interface may be an ether disposed on the main chassis. Network interface.

The first switch chip may be a Layer 2 switch chip or a Layer 3 or Layer 4 switch chip.

To implement the connection between the operating system motherboard and the first switch chip, a second external network interface is disposed on each operating system motherboard, and the second external network interface may be an Ethernet interface, such as the Ethernet interface illustrated in FIG. 1.

It can be understood that the second external network interface on the motherboard of different operating systems will be connected to different ports of the first switch chip, for example, the Ethernet interface 1 of the first operating system motherboard illustrated in FIG. 1 is connected to the first switch chip. Port 1 (port1), the Ethernet port 1 of the second operating system motherboard is connected to port 2 (port 2) of the first switch chip. In addition, FIG. 1 illustrates a port 3 (port 3) connected to a switch between the first external network interface and the first switch chip and connected to the first switch chip.

The function of the switch is mainly embodied in: when the first external network interface is inserted into the first external network interface, that is, the first external network interface is connected to the external wired network, the switch is turned on, so as can be seen from FIG. 1, the first operating system and the first The second operating system will be able to access the external network through the first switch chip.

To this end, an operating system may be selected from the N operating systems, for example, the first operating system is selected from the first operating system and the second operating system in FIG. 1 to monitor the connection of the first external network interface. When the first operating system detects that the first external network interface is connected to the external wired network, the control switch is turned on.

It can be understood that the foregoing first operating system for monitoring the first external network interface may be randomly selected from the N operating systems in advance, or may be the most powerful processing selected from the N operating systems. operating system.

In an optional implementation manner, the first operating system may have a network cable insertion and removal monitoring module. When the network cable is inserted into the first external network interface, the first external network interface sends a notification message to the network cable insertion and removal monitoring module. Informing the first operating system network cable to be inserted into the first external network interface. Similarly, when the network cable is unplugged from the first external network interface, the first external network interface sends a notification message to the network cable insertion and removal monitoring module to inform the An operating system network cable is pulled out from the first external network interface.

The access to the external network by the multiple operating systems in this embodiment is based on the premise that the network cable is inserted into the first external network interface. Therefore, the external wired network may be understood to be connected to the external network by using a wired manner. The external wireless network mentioned can be understood as being wirelessly connected to an external network.

The network communication process of the operating system will be briefly described below with reference to FIG. As shown in FIG. 1, when the first operating system detects that the first external network interface is inserted into the network cable, the switch is turned on, so that the first operating system and the second operating system access the external network through the first switch chip.

Based on this, taking the first operating system as an example, when the first operating system wants to send data to other communication devices, the communication data sequentially passes through the Ethernet port 1 of the first operating system motherboard, the first switch chip, and the first external device. The network interface is sent out and transmitted to the other communication device through the external network. It can be understood that when other communication devices want to send data to the first operating system, the communication path is reversed.

However, it is worth noting that the above communication process may differ depending on the first switch chip. Specifically, when the selected first switch chip is a Layer 2 switch chip, as another communication device wants to send data to the first operating system, when the data is transmitted to the port 3 of the first switch chip, the first switch chip will The data is output to each of the other ports, as shown in Figure 1, port1 and port2, so that the data is sent to the first operation through the Ethernet port 1 of the first operating system motherboard and the Ethernet port 1 of the second operating system motherboard. The system and the second operating system. At this time, the first operating system and the second operating system determine the data according to whether the media access control (MAC) address carried in the data corresponds to itself. Whether it is sent to itself, the second operating system determines that the data is not sent to itself, discarding the data. The first operating system is taken as an example. In this case, the MAC address corresponding to the first operating system can be regarded as the MAC address corresponding to the Ethernet port 1 on the motherboard of the first operating system.

Therefore, when the first switch chip is a Layer 2 switch chip, the processing logic of the first switch chip for the received data is only simple to receive the data from a certain port, and then forward the data to each other. The process of the port without forwarding to a specific destination party. When the first switch chip has forwarding processing logic to a specific destination communication party, for example, when a three-layer switch chip is selected, the first switch chip can directly directly data based on a communication address of the destination communication party, such as an IP address and a MAC address. Send to the destination party.

In addition, when the switch is turned on so that N operating systems can access the external network through the first switch chip, in order to realize network communication between each operating system and other external communication devices, each operating system can also be obtained through static or dynamic manner. An IP address, such as a network access device to which the communication device is connected, such as a router or a gateway, assigns a corresponding IP address to each operating system of the communication device, wherein the IP address is a second external network corresponding to each operating system motherboard. Interface, as shown in Figure 1, Ethernet port 1. At this time, optionally, the second external network interface of each operating system motherboard may be assigned an IP address in the same network segment as other communication devices connected to the same network access device, assuming that the network segment is 172.18.XX. XX, as shown in Figure 1, the external network IP address corresponding to the Ethernet interface 1 of the first operating system motherboard and the second operating system motherboard is in the network segment 172.18.XX.XX. Based on the configuration of the IP address, the first operating system and the second operating system can discover a service in another communication device on the same network segment and use the service.

In summary, in the architecture of the communication device shown in FIG. 1, when the first operating system detects that the first external network interface is inserted into the network cable, the control switch is turned on. At this time, the first operating system and the second operating system can be The first switch chip is connected to the external network, so that only by deploying the above-mentioned communication component in the communication device, multiple operating systems can be connected to the external network for network communication by inserting a network cable. Capabilities, thereby saving hardware costs and ensuring the small and lightweight requirements of communication devices.

In an actual application, when the first external network interface is not inserted into the network cable, that is, the communication device cannot access the external network through the wired manner, or it can be said that the communication device cannot access the external network by any means, In this case, the embodiment of the present application further provides a mechanism for ensuring that N operating systems implement internal communication with each other at least, as shown in FIG. 2 and FIG. 3. It can be understood that when each operating system can access an external network, each operating system can also implement communication with each other through the external network.

Optionally, N-1 first intranet interfaces for respectively connecting with the remaining N-1 operating system motherboards may be set on each of the N operating system motherboards, for example, as shown in FIG. 2 As shown, the first internal network interface (Ethernet port 2) respectively disposed on the first operating system motherboard and the second operating system motherboard implements internal communication between the first operating system and the second operating system, wherein Each Ethernet port 2 is assigned an intranet IP address, as shown in Figure 2.

The internal communication mechanism between the different operating systems provided in this embodiment is used when the operating system cannot connect to the external network. Therefore, the network cable will not be inserted in the first external network interface, and thus, when connected to the first When the first operating system of an external network interface detects that the first external network interface is not connected to the external wired network, the control switch is disconnected. At this time, the communication of the operating system can no longer be realized through the external network, and instead The network implements communication between different operating systems.

In addition to the internal communication between the operating systems in the foregoing manner, the following may be implemented in the following manner: a second switch chip is further disposed in the communication device, and each of the N operating system boards is configured to be connected to the second switch chip. The second internal network interface. As shown in FIG. 3, the first operating system motherboard and the second operating system motherboard are connected to different ports of the second switch chip through a second internal network interface (Ethernet port 3) respectively disposed thereon. The internal communication between the first operating system and the second operating system is implemented by the second switch chip, wherein the two Ethernet ports 3 are respectively assigned an intranet IP address, as shown in FIG.

Similarly, the implementation of the alternative mode is also used when the operating system cannot connect to the external network, so when the first operating system connected to the first external network interface monitors that the first external network interface is not connected to the external wired network Then, the control switch is disconnected. At this time, communication between different operating systems is realized by the second switch chip.

In practical applications, the two internal communication mechanisms may be selected according to the number of operating systems included in the communication device. For example, when the number of operating systems included is small, for example, two or three, the first may be adopted. An optional method; when there are a large number of operating systems, for example, more than three, the second alternative is adopted.

In an actual application, the N operating systems in the communication device can access the external network, that is, access the external wired network, and access the external wireless network. The internet. Therefore, the embodiment of the present application also provides a scheme for N operating systems to share an external wireless network, as shown in FIG. 4 and FIG. 5.

In this case, the foregoing communications device may further include: a third external network interface corresponding to the N operating system motherboards for connecting to the external wireless network, such as the first operation and the first operation illustrated in FIG. 4 and FIG. The third external network interface (USB1 and USB2) corresponding to the system motherboard and the second operating system motherboard.

In fact, the third external network interface may be disposed on a chassis of the communication device, and each third external network interface may mark a corresponding operating system identifier for the user to respectively correspond to the N operating system motherboards. In the three external network interfaces, select the interface that you want to insert into a wireless network card such as a WiFi network card.

Different from the third external network interface that the user inserts into the wireless network card corresponds to the first operating system, the specific processing procedure of the wireless network sharing is slightly different.

Before the wireless network sharing process is specifically described in conjunction with the embodiments shown in FIG. 4 and FIG. 5, the application scenarios corresponding to the two embodiments are described. It is assumed that the first external network interface is not inserted into the network cable, that is, N at this time. The operating system cannot access the external wired network. At this time, the first operating system controls the switch between the first external network interface and the first switch chip to be disconnected.

Based on this, as shown in FIG. 4, when the user inserts the wireless network card into the third external network interface corresponding to the first operating system motherboard (USB1 on the first operating system motherboard in FIG. 4), When the third external network interface corresponding to the system board is connected to the external wireless network, the first operating system can share the external wireless network to the second external network interface of the first operating system motherboard (the first operating system motherboard in FIG. 4) The Ethernet port 1) is shared by the first switch chip to the second external network interface of the remaining N-1 operating system boards (the Ethernet port 1 on the second operating system board in FIG. 4).

Based on this, as shown in FIG. 5, when the user inserts the wireless network card into the third external network interface corresponding to the second operating system motherboard (USB2 on the second operating system motherboard in FIG. 5), When the third external network interface corresponding to the second operating system motherboard of the remaining N-1 operating system motherboards is connected to the external wireless network, the second operating system carried on the second operating system motherboard is And the method is: sending a wireless access notification to the first operating system, and sharing the external wireless network to the second external network interface of the second operating system motherboard when receiving the sharing instruction fed back by the first operating system (in FIG. 5 The Ethernet port 1) on the motherboard of the second operating system is shared by the first switch chip to the second external network interface of the remaining N-1 operating system boards (the Ethernet on the first operating system board in FIG. 5) port 1).

As shown in FIG. 2 and FIG. 3, the second operating system sends a wireless access notification to the first operating system and the first operating system sends a sharing instruction to the second operating system, which may be as shown in FIG. 2 or FIG. 3. The internal communication mechanism is implemented. The wireless access notification is used to notify the first operating system that the wireless network can access; and the sharing instruction is used to receive other operations if the first operating system determines that the first external network interface is not connected to the external wired network. The system, such as the wireless access notification of the second operating system, can trigger the network sharing of the wireless network card inserted into the third external network interface corresponding to the second operating system motherboard.

The network sharing between different network interfaces of the same operating system motherboard is equivalent to the network sharing between the different network cards of the same device, and can be implemented based on the existing implementation manner, which is not described in this embodiment.

With the wireless network sharing mechanism provided in this embodiment, when an operating system can access an external wireless network, an operating system can be implemented by inputting only one access password of the wireless network. The sharing of the external wireless network enables N operating systems to communicate through the external wireless network, which is convenient for the user's operation, and also serves as a supplementary networking solution when the wired network is unavailable, and increases multiple communication devices. The robustness of the operating system into the network.

In actual applications, external wireless networks and external wired networks may also be accessible. In this case, an external network may be selected for communication of N operating systems in the communication device. An optional selection basis is: selecting a high priority according to a preset priority of the external wired network and the external wireless network. Among them, the priority setting can be set by combining various factors such as network bandwidth and network quality, so as to use a high-quality external network for communication. When the wireless network card is inserted into the third external network interface corresponding to the different operating system boards as shown in FIG. 4 and FIG. 5, the processing procedure of the external network selection is slightly different, and the difference is described in conjunction with FIG. 6 and FIG. 7.

Specifically, in conjunction with FIG. 6, if the first operating system monitors that the first external network interface is connected to the external wired network, and if the third external network interface corresponding to the first operating system motherboard (USB1 illustrated in FIG. 6) is connected to The external wireless network controls the switch to be turned on according to the preset priority of the external wired network and the external wireless network, or the control switch is disconnected and the external wireless network is shared to the second external network interface of the first operating system motherboard (figure The Ethernet port on the first operating system board indicated in 6 is 1). If the priority of the external wired network is higher than the priority of the external wireless network, the control switch is turned on. At this time, each operating system performs network communication through an external wired network, as shown in FIG. 6. Conversely, if the priority of the external wired network is lower than the priority of the external wireless network, then the first operating system control switch is disconnected and the external wireless network is shared to the first operating system motherboard according to the process shown in FIG. The process of the second external network interface, at this time, each operating system performs network communication through an external wireless network.

Referring to FIG. 7, if the first operating system monitors that the first external network interface is connected to the external wired network, and if the first operating system receives the second operating system, the second operating system of the N-1 operating system motherboards carries the second The wireless access notification sent by the operating system controls the switch to be turned on according to the preset priority of the external wired network and the external wireless network, and feeds back the instruction to the second operating system, so that the second operating system gives up using the external wireless network; Alternatively, the control switch is turned off and feedback instructions are fed back to the second operating system to cause the second operating system to share the external wireless network to other operating systems. The wireless access notification is sent by the second operating system when the third external network interface corresponding to the second operating system motherboard is connected to the external wireless network.

As shown in FIG. 7, when the wireless network card is inserted into the third external network interface corresponding to the second operating system motherboard, USB2, the first operating system learns that the first external network interface is connected to the external wired network and the second operating system After the USB2 of the main board is inserted into the wireless network card, if the priority of the external wired network is lower than the priority of the external wireless network, the first operating system control switch is disconnected, and the sharing instruction is fed back to the second operating system, and the second operating system The process of sharing the external wireless network to the second external network interface of the first operating system motherboard is performed according to the process shown in FIG. 5, at which time each operating system performs network communication through the external wireless network.
