In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, a method of communication is provided. The communication method is applied to network equipment which comprises a plurality of radio frequency devices. The communication method comprises the following steps: and receiving a first message from the terminal equipment and sending a second message to the first radio frequency device. The first message is used for requesting a first radio frequency service, the first radio frequency device is a radio frequency device with idle resources in a plurality of radio frequency devices, the second message is used for indicating the first radio frequency device to provide the first radio frequency service for the terminal equipment, and the plurality of radio frequency devices support the first radio frequency service.

Based on the communication method described in the first aspect, since the plurality of radio frequency devices all support the first radio frequency service, the network device may allocate the first radio frequency device having idle resources to the terminal device, so as to provide the first radio frequency service for the terminal device. Therefore, compared with the network equipment which only supports a fixed radio frequency device, the radio frequency device can be prevented from being limited in use through the distribution of the radio frequency devices, and the utilization rate of radio frequency resources is improved.

Therefore, the network equipment can select corresponding parameters according to actual requirements, so that the determined first radio frequency device can meet the actual requirements. For example, if a high quality rf service is required, the first rf device may be determined according to the signal strength to improve the quality of service of the first rf service. For another example, if a high-reliability rf service is required, the first rf device may be determined according to the maximum load and the current load, so as to avoid a situation that the first rf device cannot provide the first rf service due to an excessively high load, thereby improving the reliability of the first rf service.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application will be first described in detail by taking the communication system shown in fig. 1 as an example. Fig. 1 is a schematic structural diagram of a communication system to which the communication method provided in the embodiment of the present application is applied.

As shown in fig. 1, the communication system includes a network device and a terminal device.

The network device is a device located on the network side of the communication system and having a wireless transceiving function or a chip system that can be installed on the device. The network devices include, but are not limited to: an Access Point (AP) in a wireless fidelity (WiFi) system, such as a home gateway, a router, a server, a switch, a bridge, etc., an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (NodeB, or home Node B, HNB), a Base Band Unit (BBU), the wireless relay Node, the wireless backhaul Node, the transmission point (TRP or TP), etc., may also be 5G, such as a gNB in a New Radio (NR) system, or a transmission point (TRP or TP), one or a group (including multiple antenna panels) of antenna panels of a base station in the 5G system, or a network Node forming the gNB or the transmission point, such as a baseband unit (BBU), or a Distributed Unit (DU), a roadside unit (RSU) with a base station function, etc.

Alternatively, the network device may include a plurality of rf devices, such as a first rf device, a second rf device, a third rf device, and so on. Wherein the plurality of radio frequency devices may include: the network equipment comprises a built-in radio frequency device, such as a built-in radio frequency chip, and/or an external extended radio frequency device, such as a radio frequency extension card, so as to realize the full utilization of radio frequency resources. In addition, each rf device may be a multi-mode rf device, or each rf device may support multiple wireless communication systems, so as to support multiple rf services corresponding to the multiple wireless communication systems. Wherein, the plurality of radio frequency devices support the same radio frequency service, such as the first radio frequency service. The plurality of wireless communication systems may include: bluetooth (BLE) communication, zigbee (Zigbee) communication, radio Frequency Identification (RFID) communication, or long range radio (LoRa) communication, and the like, without limitation. Accordingly, the plurality of radio frequency services may include a plurality of: BLE communication service, zigbee communication service, RFID communication service, loRa communication service, or the like, without limitation. It can be seen that the wireless communication system supported by each rf device may correspond to the supported rf service. In other words, if a radio frequency device supports a certain wireless communication system, the radio frequency device supports a radio frequency service corresponding to the wireless communication system, for example, if the radio frequency device supports BLE communication, the radio frequency device may support BLE communication service. In this way, each RF device may selectively provide RF services from among the plurality of RF services supported. For example, each radio frequency device may provide multiple radio frequency services simultaneously, such as providing BLE communication service and Zigbee communication service simultaneously, or may switch a currently provided radio frequency service, such as switching from Zigbee communication service to BLE communication service.

The terminal device may be a terminal with a wireless transceiving function or a chip system that can be installed in the terminal, and may access the communication system through a radio frequency service provided by the radio frequency device. The terminal device may also be referred to as an internet of things terminal, user Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a vehicle-mounted terminal, an RSU with a terminal function, and the like.

It should be noted that the communication method provided in this embodiment of the present application may be applicable to communication between the terminal device and the network device shown in fig. 1, and for specific implementation, reference may be made to the following method embodiment, which is not described herein again.

It should be noted that the solutions in the embodiments of the present application may also be applied to other communication systems, and the corresponding names may also be replaced with names of corresponding functions in other communication systems.

It should be appreciated that fig. 1 is a simplified schematic diagram of an example for ease of understanding only, and that other network devices, and/or other terminal devices, not shown in fig. 1, may also be included in the communication system.

The communication method provided in the embodiment of the present application will be specifically described below with reference to fig. 2.

Exemplarily, fig. 2 is a schematic flowchart of a communication method provided in an embodiment of the present application. The communication method may be applied to communication between the terminal device and the network device shown in fig. 1.

As shown in fig. 2, the communication method includes the steps of:

s201, the terminal device sends a first message, and the network device receives the first message from the terminal device.

The first message may be a message or a packet for requesting the first radio frequency service, or the first message may be used to request the first radio frequency service, and may include an Identity (ID) of the terminal device. In particular, the first message may be a beacon message, such as an ADV _ INC message, which may be BLE, for requesting BLE service. It can be seen that the name of the first message may correspond to the type of the first radio frequency service, that is, the terminal device may implicitly request the radio frequency service of the corresponding type by the name of the message, so that the content of the message may be simplified, and further, the communication efficiency may be improved.

Wherein the terminal device may broadcast the first message. Accordingly, a network device, such as a radio frequency device of the network device, may receive the first message. For example, if a plurality of radio frequency devices provide the first radio frequency service, the plurality of radio frequency devices may all receive the first message.

For ease of understanding, the following description is given by way of example.

Illustratively, the plurality of radio frequency devices includes: and a radio frequency chip and a radio frequency expansion card are arranged in the radio frequency expansion card. The radio frequency service provided by the built-in radio frequency chip can be switched among a plurality of supported radio frequency services, such as being switched into a BLE communication service, and the radio frequency expansion card can simultaneously provide a plurality of radio frequency services, such as simultaneously providing a BLE communication service, a Zigbee communication service and an RFID communication service. If the terminal equipment broadcasts the ADV _ INC message of BLE, both the built-in radio frequency chip and the radio frequency expansion card can receive the ADV _ INC message. However, if the radio frequency service provided by the built-in radio frequency chip is switched from the BLE communication service to the Zigbee communication service, the built-in radio frequency chip cannot receive the ADV _ INC message.

S202, the network equipment sends a second message to the first radio frequency device.

The first rf device may be a multi-mode rf device, and may be an rf device with idle resources in the plurality of rf devices. That is to say, the first rf device may support multiple wireless communication systems to provide multiple rf services, such as the first rf service, the second rf service, the third rf service, and so on, to meet various rf service requirements of the terminal device, thereby further improving diversity and applicability of the rf services. And if the current load of the first radio frequency device is less than the maximum load supported by the first radio frequency device, determining that idle resources exist. For example, on the basis that the first radio frequency device supports simultaneous access to 4 terminal devices, if the first radio frequency device has simultaneously accessed to 3 terminal devices, there is an idle resource, but if the first radio frequency device has simultaneously accessed to 4 terminal devices, there is no idle resource.

Optionally, the first radio frequency device may also be a radio frequency device with the smallest load among the multiple radio frequency devices, and a situation that the first radio frequency device cannot provide the first radio frequency service due to an excessively high load may be avoided, so that reliability of the first radio frequency service is improved. And/or, the first radio frequency device may also be a radio frequency device corresponding to a signal with the largest signal strength among signals transmitted and/or received by the plurality of radio frequency devices, so as to ensure that the quality of the first radio frequency service is better, the service is more stable, and the user experience is better.

Thus, it can be seen that the network device may determine the first radio frequency device based on the idle resources of the radio frequency device, or based on a combination of the idle resources of the radio frequency device and the load size and/or signal strength. Described separately below.

Scenario a. Determine a first radio frequency device from an idle resource of the radio frequency device.

The network device stores the operating parameters of each of the plurality of radio frequency devices, so that the network device can determine the first radio frequency device having idle resources according to the operating parameters. Wherein the operating parameters may include one or more of: supported wireless communication system, provided radio frequency service, maximum supported load, or current load.

Specifically, the network device may determine, from the plurality of radio frequency devices, a radio frequency device that supports the first radio frequency service according to a wireless communication system supported by each radio frequency device. Then, the network device may determine, from among the radio frequency devices supporting the first radio frequency service, a radio frequency device providing the first radio frequency service according to the radio frequency service provided by each radio frequency device. Finally, the network device may determine, from the radio frequency devices providing the first radio frequency service, a radio frequency device having an idle resource, that is, the first radio frequency device, according to the maximum load supported by each radio frequency device and the current load. If there are multiple rf devices with idle resources, one of the multiple rf devices may be selected as the first rf device.

For the sake of understanding, the above-mentioned built-in rf chip and rf expansion card are used as examples for description.

As a first example, the operating parameters of the above-mentioned built-in rf chip and rf expansion card stored by the network device may be as shown in table 1 below.

TABLE 1

As can be seen from table 1, if the first rf service is a BLE communication service, the network device may determine that both the internal rf chip and the rf expansion card support the BLE communication service, and determine that both the internal rf chip and the rf expansion card can provide the BLE communication service. Finally, the network device may determine that the built-in radio frequency chip has no idle resource according to that the maximum load supported by the built-in radio frequency chip is 4 and the current load is 4, and determine that the radio frequency expansion card has idle resource according to that the maximum load supported by the radio frequency expansion card is 8 and the current load is 3. That is, in this case, the radio frequency expansion card is determined to be the first radio frequency device.

In addition, if the maximum load supported by the built-in radio frequency chip is 4 and the current load is 3, it is determined that the built-in radio frequency chip also has idle resources. In this case, the network device may determine that any one of the built-in rf chip and the rf expansion card is the first rf device.

And B, determining the first radio frequency device according to the idle resources and the load size of the radio frequency device.

Similarly to the scenario a, the network device also stores the operating parameters of each rf device, so as to determine the rf device providing the first rf service from the multiple rf devices. For determining the specific implementation of the radio frequency device providing the first radio frequency service, reference may be made to the related description in the scenario a, and details are not described herein again. Then, the network device may determine, from the radio frequency devices providing the first radio frequency service, a radio frequency device having a minimum load and having idle resources, that is, the first radio frequency device, according to the maximum load supported by each radio frequency device and the current load. The minimum load may refer to the current minimum load, or may refer to the minimum ratio of the current load to the maximum load supported, so that the network device may reasonably select a determination method of the minimum load according to actual requirements, so as to ensure that the determined radio frequency chip can meet the actual requirements. In addition, if there are a plurality of rf devices with idle resources and the minimum load, one of the rf devices may be selected as the first rf device.

For the sake of understanding, the following description continues by taking the above-mentioned built-in rf chip and rf expansion card as examples.

As a second example, the operating parameters of the built-in rf chip and the rf expansion card saved by the network device may be as shown in table 2 below.

TABLE 2

As can be seen from table 2, if the first radio frequency service is a BLE communication service, the network device may determine that both the built-in radio frequency chip and the radio frequency expansion card support the BLE communication service, and determine that both the built-in radio frequency chip and the radio frequency expansion card can provide the BLE communication service. Finally, the network device may determine that both the internal radio frequency chip and the radio frequency expansion card have idle resources according to that the maximum load supported by the internal radio frequency chip is 4 and the current load is 2, and according to that the maximum load supported by the radio frequency expansion card is 8 and the current load is 3. In this case, if the minimum load means that the current load is minimum, the minimum load of the internal rf chip is determined (the minimum load is 2 is smaller than the minimum load is 3), so that the internal rf chip is determined to be the first rf device. Or, if the load is minimum, that is, the ratio between the current load and the maximum load supported is minimum, determining that the load of the radio frequency expansion card is minimum (the load is minimum 3/8 less than the load is minimum 2/4), and thus determining that the radio frequency expansion card is the first radio frequency device.

And C, determining the first radio frequency device according to the idle resources and the signal strength of the radio frequency device.

Different from the scenario a, the working parameters of each rf device stored by the network device not only include one or more of the following: the supported wireless communication system, the provided radio frequency service, the supported maximum load, or the current load may further include: signal strength, such as the signal strength of a transmitted or received signal. The signal strength may be reported by each rf device. For example, if the signal strength is the signal strength of the received message, the radio frequency device receives the message, and if the latest message is received, the radio frequency device may report not only the message but also the signal strength of the message, such as the signal strength of the first message, and/or if the signal strength is the signal strength of the transmitted message, the radio frequency device transmits the message, and if the latest message is transmitted, the radio frequency device may also report the signal strength of the message, so that the network device knows the signal strength of each radio frequency device. Of course, reporting the signal strength is only an exemplary way and is not limited. For example, the network device may also pre-configure the signal strength of each radio frequency device.

Thus, the network device may determine, from the plurality of radio frequency devices, a radio frequency device having idle resources according to the operating parameter. For specific implementation of the radio frequency device with idle resources, reference may be made to the related description in the scenario a, which is not described herein again. Further, if there is one radio frequency device with idle resources, the network device may determine that the radio frequency device with idle resources is the first radio frequency device. However, if there is more than one radio frequency device having idle resources, the network device may determine, from the radio frequency devices having idle resources, the radio frequency device having the highest signal strength as the first radio frequency device according to the signal strengths of the plurality of radio frequency devices. If there are a plurality of rf devices with the highest signal strength, one of the rf devices may be selected as the first rf device.

As a third example, the operating parameters of the above-mentioned built-in rf chip and rf expansion card stored by the network device may be as shown in table 3 below.

TABLE 3

As can be seen from table 3, if the first rf service is a BLE communication service, the network device may determine that both the internal rf chip and the rf expansion card have idle resources. For specific implementation of determining that both the built-in rf chip and the rf expansion card have idle resources, reference may be made to the related description in the first example, which is not described herein again. In this case, the network device may determine that the signal strength of the built-in rf chip is the maximum (the signal strength is 4 greater than the signal strength is 3) according to the signal strength, so as to determine that the built-in rf chip is the first rf device.

And D, determining the first radio frequency device according to the idle resources, the load size and the signal strength of the radio frequency device.

Similar to scenario C above, the network device may store the operating parameters of each rf device, including one or more of the following: supported wireless communication system, provided radio frequency service, supported maximum load, current load, or signal strength, such as signal strength of a transmitted or received signal. In this way, the network device may determine, from the plurality of rf devices, an rf device having a minimum load and having an idle resource according to the operating parameter. For determining the specific implementation of the radio frequency device with the minimum load and having idle resources, reference may be made to the related description in the above scenario B, which is not described herein again. Further, if there is one radio frequency device with idle resources and the minimum load, the network device may determine that the radio frequency device with idle resources and the minimum load is the first radio frequency device. If there is more than one radio frequency device with idle resources and the minimum load, the network device may determine, according to the respective signal strengths of the plurality of radio frequency devices, a radio frequency device with the maximum signal strength, that is, the first radio frequency device, from the radio frequency devices with idle resources and the minimum load.

As a fourth example, the operating parameters of the above-mentioned built-in rf chip and rf expansion card stored by the network device may be as shown in table 4 below.

TABLE 4

As can be seen from table 4, if the first rf service is BLE communication service and the minimum load is the smallest ratio between the current load and the maximum load supported, the network device may determine that both the built-in rf chip and the rf expansion card have idle resources and the load is the minimum (the load is 2/4 minimum, which is equal to the load is 4/8 minimum). For a specific implementation that both the built-in rf chip and the rf expansion card have idle resources and have the minimum load, reference may be made to the related description in the second example, which is not described herein again. In this case, the network device may determine that the signal strength of the built-in rf chip is the maximum (the signal strength is 4 greater than the signal strength is 3) according to the signal strength, so as to determine that the built-in rf chip is the first rf device.

It should be noted that, in the scenarios a-D, if there is a radio frequency device supporting the first radio frequency service but the first radio frequency service is not currently provided, the network device may determine, according to the current load of the radio frequency device, whether the currently provided radio frequency service can be switched to the first radio frequency service. For example, if the current load of the radio frequency device is 0, it is determined that the first radio frequency service may be switched, and otherwise, the first radio frequency service may not be switched. Further, if the network device determines that the network device can be switched to the first radio frequency service and determines that the radio frequency device is the first radio frequency device, the network device controls the radio frequency device to provide the first radio frequency service so that the terminal device can access the first radio frequency service. For determining the specific implementation of the first rf device, reference may be made to the related descriptions in the scenarios a-D, which are not described herein again.

As a fifth example, the operating parameters of the above-mentioned built-in rf chip and rf expansion card saved by the network device may be as shown in table 5 below.

TABLE 5

As can be seen from table 5, the internal rf chip supports BLE communication, but currently, BLE communication service is not provided, but Zigbee communication service is provided. If the first radio frequency service is a BLE communication service and the current load of the built-in radio frequency chip is 0, the switching to the BLE communication service is determined. In this case, the built-in rf chip may participate in the determination of the first rf device, or the network device may determine the first rf device from the built-in rf chip and the rf expansion card. And if the network equipment determines that the built-in radio frequency chip is the first radio frequency device, the built-in radio frequency chip is controlled to switch from providing the Zigbee communication service to providing the BLE communication service so that the terminal equipment can access the device. Of course, if the current load of the internal radio frequency chip in table 5 is not 0, it is determined that the internal radio frequency chip may not be switched to BLE communication service, and thus it is determined that the radio frequency expansion card is the first radio frequency device.

In summary, in conjunction with scenarios a-D described above, the operating parameters may include one or more of the following: the wireless communication system supported by each rf device, the rf service provided by each rf device, the maximum load supported by each rf device, the current load of each rf device, or the signal strength of each rf device. Therefore, the network equipment can select corresponding parameters according to actual requirements, so that the determined first radio frequency device can meet the actual requirements. For example, if a high quality rf service is required, the first rf device may be determined according to the signal strength to improve the quality of service of the first rf service. For another example, if a high-reliability rf service is required, the first rf device may be determined according to the maximum load and the current load, so as to avoid a situation that the first rf device cannot provide the first rf service due to an excessively high load, thereby improving the reliability of the first rf service.

Further, after determining the first rf device, the network device may send a second message to the first rf device.

The second message may be used to instruct the first rf device to provide the first rf service for the terminal device. In particular, the second message may be a radio frequency connection service initiation message, which may include the identification of the terminal device and the first indication information. The first indication information may be used to indicate that the first radio frequency device provides the first radio frequency service for the terminal device. Correspondingly, after receiving the second message, the first radio frequency device can establish connection with the terminal device according to the first indication information, so that the first radio frequency service is provided for the terminal device.

Optionally, before S202, the network device may acquire the above-mentioned operating parameters in advance.

For example, as an embodiment, the operating parameter may be reported by each rf device. For example, when the network device is powered on, or when the radio frequency service provided by each radio frequency device and the current load change, each radio frequency device may report the latest operating parameter of the radio frequency device by itself. Of course, each rf device may also periodically report the latest operating parameter, which is not limited thereto.

As a fifth example, the wireless communication system supported by the built-in rf chip includes: BLE communication, zigbee communication, and RFID communication, the provided radio frequency service is Zigbee communication service, the maximum load supported is 4, and the current load is 0. If the radio frequency service provided by the built-in radio frequency chip is switched from the Zigbee communication service to the RFID communication service, the built-in radio frequency chip may report the latest working parameter, as shown in table 6 below.

TABLE 6

In addition, the wireless communication system supported by the built-in radio frequency chip comprises: BLE communication, zigbee communication, and RFID communication, the radio frequency service provided includes BLE communication, zigbee communication, and RFID communication, the maximum load supported is 8, and the current load is 6. If the current load of the rf expansion card changes from 6 to 7, the rf expansion card may report the latest operating parameters, as shown in table 7 below.

TABLE 7

For another example, as another embodiment, the operating parameters may be obtained by the network device actively from multiple radio frequency devices. For example, after the network device is powered on, the latest operating parameters of each rf device may be periodically obtained from the rf device.

It should be noted that, for the current load of each radio frequency device, the current load may be reported by the radio frequency device, or obtained by the network device from the radio frequency device, or determined by the network device. For example, the network device may record the number of terminal devices accessing the radio frequency device, thereby determining the current load of the radio frequency device.

Optionally, before S202, the communication method may further include: and transmitting the data of the terminal equipment to the first radio frequency device.

After the network device determines the first rf device, a mapping relationship between the first rf device and the terminal device may be established to indicate that the first rf device has been allocated to the terminal device. In this way, when the network device receives data of the terminal device, for example, the data from the internet of things or the wireless local area network, the network device may send the data to the first radio frequency device according to the mapping relationship, so that the first radio frequency device sends the data to the terminal device.

Optionally, the communication method may further include: if there is no service between the first rf device and the terminal device, a third message may be sent to the first rf device.

Wherein, no service between the first radio frequency device and the terminal device may be: the first radio frequency device is not in communication with the terminal device for a period of time. That is, the network device may monitor, e.g., periodically monitor, whether the first rf device is in communication with the terminal device. And if the first radio frequency device is determined not to be communicated with the terminal equipment within a period of time, such as the current period or a plurality of recent periods, determining that no service exists between the first radio frequency device and the terminal equipment.

The third message may be used to instruct the first rf device to stop providing the first rf service for the terminal device, for example, the third message may be an rf connection service cancellation message, and may include an identifier of the terminal device and the second indication information. The second indication information may be used to indicate that the first radio frequency device stops providing the first radio frequency service for the terminal device. Correspondingly, after receiving the third message, the first radio frequency device may disconnect the connection with the terminal device according to the second indication information, thereby stopping providing the first radio frequency service for the terminal device. Therefore, the radio frequency resource of the first radio frequency device can be recycled, so that the first radio frequency device can provide radio frequency service for other terminal equipment, and the operation efficiency of the first radio frequency device is improved.

It should be noted that, because whether the first radio frequency device and the terminal device communicate with each other within a period of time can accurately reflect whether a service exists, a service disconnection between the first radio frequency device and the terminal device by mistake can be avoided, and thus, service reliability and stability can be ensured.

Optionally, the communication method may further include: the network device receives a registration message sent by each of the plurality of radio frequency devices. Wherein the registration message may include the above-mentioned operating parameters of the radio frequency device. Therefore, the network equipment can record the corresponding relation between the radio frequency device and the working parameters of the radio frequency device, so that the radio frequency device such as the first radio frequency device which needs to provide radio frequency service for the terminal equipment can be quickly determined according to the corresponding relation, and the operation efficiency of the network equipment can be improved. The specific implementation of the correspondence relationship can be as shown in tables 1 to 7, and is not described herein again.

Alternatively, the processor 401, the memory 402, and the transceiver 403 may be integrated on a main control board (not shown in fig. 4) of the communication device 400. On this basis, if the radio frequency device is a radio frequency device of the communication apparatus itself, such as a built-in radio frequency chip 404 (shown by a dotted line in fig. 4), the built-in radio frequency chip 404 may also be integrated on the main control board and connected to the processor 401 through a communication bus, so as to implement the functions described in the above communication method, such as providing the first radio frequency service.

A virtual machine refers to a complete computer system with complete hardware system functionality, which is emulated by software, running in a completely isolated environment.

The network device is a virtual host, a virtual router or a virtual switch. Through reading the application, a person skilled in the art can combine the NFV technology to virtually simulate a network device with the above functions on a general physical server. And will not be described in detail herein.

The container may be configured as a network device. For example, the network device may be created by a corresponding mirror image, for example, 1 container instance may be created for proxy-container by providing a mirror image of a container (proxy-container) of the proxy service, for example, for the container instance proxy-container1, and the container instance proxy-container1 may be provided as the network device. When the container technology is adopted for implementation, the network device can run by utilizing the inner core of the physical machine, and a plurality of network devices can share the operating system of the physical machine. Different network devices can be isolated by container technology. The containerized network device may run in a virtualized environment, such as a virtual machine, or the containerized network device may run directly in a physical machine.

For example, the virtualization device may be Pod, which is a container arrangement engine of *** open source, such as kubernets, also abbreviated as K8s, and is a basic unit for deploying, managing, and arranging containerized applications. The Pod may include one or more containers. Each container in the same Pod is typically deployed on the same host, so each container in the same Pod can communicate through the host and can share the storage resources and network resources of the host. The Pod may be configured as a network device. For example, specifically, a Pod, that is, a container-based service (CaaS) may be instructed to create a Pod, and the Pod may be provided AS a route management device or AS management device.
