This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on April 22, 2019, the application number is 201910324562.4, and the invention title is "Data Management Method, LEPM and MEPM", the entire content of which is incorporated into this application by reference .

Technical field

Mobile-edge computing (MEC) uses wireless access networks to provide nearby services and cloud computing functions required by users. After the cloud computing function is deployed to the edge of the network, a carrier-grade service environment with high performance, low latency and high bandwidth can be created, which accelerates the rapid download of various content, services and applications in the network, and allows consumers to enjoy higher Quality network experience.

Currently, the mobile edge computing architecture is mainly composed of two parts: the mobile edge host and the mobile edge computing management system. A mobile edge host is an entity that includes a mobile edge platform and a virtualized infrastructure, and provides computing, storage, and network resources for MEC applications. And the mobile edge computing management system includes MEC orchestrator (multi-access edge orchestrator), mobile edge platform manager (mobile edge platform manager, MEPM), virtual infrastructure manager (virtualisation infrastructure manager, VIM) and so on. Among them, the MEC orchestrator is used to maintain an overall view of all mobile edge hosts, available resources, and available MEC services in the MEC system, and to trigger the instantiation and termination of applications. MEPM is used to manage the MEC platform, manage the life cycle of MEC applications, and manage flow rules and domain name system (DNS) rules for MEC applications. At present, the mobile edge host is connected to the MEPM, and then MEPM manages the MEC application on the mobile edge host. For example, MEPM can issue management commands such as deployment, installation, start-stop, uninstall and delete, elastic scaling, capacity expansion, etc. of MEC applications to the mobile edge host, and the mobile edge platform locally processes these commands to perform local edge applications. Operations such as life cycle management and health monitoring. MEPM takes centralized control of mobile edge hosts and records all mobile edge hosts and MEC application data it manages.

However, in the existing architecture, the MEPM is connected to the mobile edge host, and then the MEPM performs corresponding management operations on the mobile edge host and the MEC application on the mobile edge host.

Detailed ways

The embodiments of the present application provide a data management method and a data management device, which are used to reduce the management load of MEPM, avoid or prevent MEPM from becoming a bottleneck to the performance of the entire network, and problems such as slow response of MEPM management actions and increased time delay. .

Please refer to Figure 1A. Figure 1A is a schematic structural diagram of a mobile edge host management network provided by an embodiment of the application; the management network includes a mobile edge host, a local edge platform manager (LEPM), and MEPM And VIM etc. Among them, the local edge platform manager LEPM1 is integrated in the mobile edge host 1, which has the ability to connect to other mobile edge hosts in the area 1 and perform local small-scale management of the mobile edge hosts in the area 1. The LEPM1 mainly provides the following management capabilities: Application lifecycle management of MEC applications on mobile edge hosts in the network where area 1 is located (for example, MEC application deployment, start, stop, restart, uninstall, monitoring, elastic scaling, capacity expansion, etc.) , Establish a connection with the mobile edge platform manager MEPM, process the commands issued by MEPM, and report the application instance data and running status data of the MEC application managed by LEPM1. The network where the area 1 managed by LEPM1 is located can be in one In the local area network, it can also be in a subnet. The size of the network in which area 1 is located is determined by the geographical distribution of the mobile edge host, the mobile edge platform (MEP) and the mobile edge host managed by the LEPM1 The computing power is determined. Secondly, the LEPM1 can be connected to the VIM to apply for computing resources, storage resources, or network resources required by MEC applications, or to release resources that are no longer used.

MEPM has the ability to establish connections with LEPMs in each area, so as to issue management commands to LEPM, or receive application instance data or MEC application running status data from LEPM to update its data. The function of LEPM2 in area 2 shown in FIG. 1A is similar to that of LEPM1, and will not be introduced here.

Since LEPM1 needs to establish a connection with MEPM, an embodiment of the present application proposes to realize the establishment of a connection between LEPM1 and MEPM through an Mm5-r interface. The Mm5-r interface has interface capabilities related to establishment, data synchronization, and data transmission. LEPM1 can perform application life cycle operations on the closed loop of the network where area 1 is located, and through interaction with VIM, it can apply for resources for MEC applications or release resources occupied by MEC applications. Therefore, a new Mm6-1 interface is added between LEPM1 and VIM, and a connection is established through the Mm6-1 interface, so as to realize the interaction with VIM and realize the operation of the application life cycle. The mobile edge host 3 can be connected to LEPM through Mm5-1, so that LEPM1 can realize application management on the mobile edge host 3.

Therefore, it can be seen from Fig. 1A that the mobile edge host it manages is connected through LEPM, and then LEPM is connected to MEPM to form a cascaded network of mobile edge hosts. LEPM can manage the mobile edge hosts in the area, effectively sharing the management load of MEPM, and cascading networking can effectively reduce the MEPM's network entrance bandwidth. In this management network, MEPM shares computing tasks and network resource overhead among multiple LEPMs, so that MEPM is no longer a management bottleneck, and avoids or reduces problems such as slow response of MEPM management actions and increased latency.

It should be noted that FIG. 1A only shows area 1 and area 2. LEPM1 manages mobile edge hosts in the network where area 1 is located, and LEPM2 manages mobile edge hosts in the network where area 2 is located. In actual applications, more areas can be included, and then each LEPM is connected with the mobile edge platform manager to realize cascading networking, which is not specifically limited by this application. FIG. 1A is only to illustrate the data management method of the embodiment of the present application.

In this embodiment, FIG. 1A shows a solution in which LEPM and MEP are deployed on a mobile edge host at the same time, that is, the mobile edge host is an edge central node device in the area and has local application management capabilities. In practical applications, the LEPM can also be deployed separately, that is, it occupies a mobile edge host, and the MEP is not deployed on this mobile edge host. As shown in Figure 1B, Figure 1B is the management network of the mobile edge host provided by the embodiment of the application. Another structural diagram; in Figure 1B, LEPM is connected to MEP respectively to provide MEPM with the functions of connection and communication with MEP. Other mobile edge hosts in the local network only deploy MEP, and then connect to the LEPM respectively to form local management Network, this application is not limited.

The following describes the data management method in the embodiment of the present application from the perspective of LEPM. Please refer to FIG. 2. An embodiment of the data management method in the embodiment of the present application includes:

201. LEPM receives management commands sent by MEPM.

Wherein, the management command is a management task issued by the MEPM for the LEPM. There are many specific management commands, such as: application instantiation command and application instance termination command.

202. LEPM executes corresponding operations according to the management command.

For example, when the management command is an application instantiation command, the LEPM applies for resources for the MEC application according to the application instantiation command, and creates an MEC application through the resources and runs the MEC application. Management commands are issued to LEPM through MEPM, and LEPM performs corresponding management operations, thereby reducing the management load of MEPM. When the management command is an application instantiation command or an application instance termination command, the specific execution operation of LEPM is described in detail in the subsequent embodiment of FIG. 3 and the embodiment of FIG. 5, and will not be repeated here.

203. LEPM sends a management command response message to MEPM.

The LEPM sends a management command response message to the MEPM, so that the MEPM determines that the LEPM has performed the corresponding management operation according to the management command response message, and updates its local data according to the management command response message.

For example, after LEPM applies for resources for the MEC application according to the application instantiation command, and after the MEC application is created and the MEC application is run through the resources, LEPM sends a management command response message to the MEPM, and the management command response message carries the MEC application application Instance data, MEPM records the application instance data of the MEC application, and records the corresponding relationship between the MEC application and the LEPM, so that the MEPM can query the application instance data of the MEC application or terminate the application instance of the MEC application. At this time, the LEPM can be determined according to the corresponding relationship, and corresponding management commands can be issued to the LEPM.

In the embodiment of this application, the LEPM receives the management command sent by the MEPM, and the management command carries the management task assigned by the MEPM to the LEPM; then, the LEPM executes the corresponding operation according to the management task, and sends a management command response message to the MEPM to Make MEPM update its local data according to the management command response message. Therefore, in the technical solution of the present application, the management commands issued by MEPM are received through LEPM, and corresponding operations are performed according to the management commands. There is no need for MEPM to perform management operations, thereby reducing the management load of MEPM and avoiding or preventing MEPM from becoming network-wide performance The bottleneck of MEPM and the slow response of MEPM management actions and increased time delay.

The following describes the specific process of the LEPM performing the management operation when the management command exemplified in step 202 in FIG. 2 is an application instantiation command or an application instance termination command, with reference to specific embodiments.

Please refer to FIG. 3, which is a schematic diagram of a data management method provided by an embodiment of the application. The management command is an application instantiation command. FIG. 3 shows the specific process of LEPM applying for resources for the MEC application according to the application instantiation command, creating the MEC application and running the MEC application through the resources. Refer to Figure 3. The method includes:

301. MEPM obtains an application instantiation command.

Wherein, the application instantiation command carries location information of the target mobile edge host, and the target edge mobile host is the mobile edge host that installs and runs the MEC application.

Exemplarily, the tenant initiates an application instantiation command through an operation support system (OSS); then, OSS sends the application instance command to the MEC orchestrator; then MEPM receives the application instantiation command sent by the MEC orchestrator .

302. The MEPM determines the LEPM according to the location information of the target mobile edge host carried in the application instantiation command.

Exemplarily, the specific determination process may be that the MEPM is determined according to the geographic location information provided by the LEPM to the MEPM during registration and the location information of the target mobile edge host. When the location information is consistent, it may be determined to execute the LEPM. Application instantiation management operations.

The following describes the registration process of LEPM in the embodiment of this application through FIG. 4. Please refer to FIG. 4. The method includes:

401. LEPM sends a registration request message to MEPM.

Exemplarily, when LEPM is started, LEPM actively establishes a connection with MEPM through the Mm5-r interface as shown in Figure 1A, and then LEPM sends a registration request message to MEPM, and the registration request message includes LEPM's access address, location information, and attribute information , Identity authentication data and information of the mobile edge host managed by the LEPM.

Wherein, the access address includes the service IP address and port number of the LEPM, or the service domain name of the LEPM.

The location information includes the network name of the network where the LEPM is located or the geographic location of the LEPM.

The attribute information includes the name of the LEPM or the description of the LEPM.

The information of the mobile edge host managed by the LEPM includes the identification ID list of the mobile edge host managed by the LEPM, etc.

The identity authentication data includes the identity credential of the LEPM (for example, the security certificate and/the key of the LEPM, and the security certificate and the key are allocated by the MEPM for the LEPM).

402. The MEPM determines the LEPM as the LEPM managed by the LEPM according to the location information of the LEPM.

The MEPM determines that the LEPM is within the range of the network to which it is connected according to the location information of the LEPM, and the MEPM determines that the LEPM is the LEPM it manages.

403. The MEPM verifies the LEPM according to the identity verification data of the LEPM, and obtains a verification result.

Exemplarily, the MEPM determines whether it is consistent with the security certificate or key of the LEPM stored locally according to the security certificate and/or key carried in the registration request message. If they are consistent, the MEPM can determine that the LEPM verification is successful; if not, Then MEPM determines that the LEPM verification has failed.

404. The MEPM sends a registration response message to the LEPM through the access address of the LEPM.

In step 403, when the LEPM verification succeeds, the MEPM sends a registration response message to the LEPM through the access address of the LEPM, and the registration response message carries the identification ID assigned by the MEPM to the LEPM; optionally, the registration response message also The access control data of the LEPM is carried, and the access control data is used to indicate that the LEPM can interact with the MEPM without performing identity verification again within a preset period of time. For example, the MEPM may send a registration response message to the LEPM through the IP address and port number of the LEPM.

405. The LEPM determines the identifier assigned to it by the MEPM according to the registration response message.

The LEPM can determine the identity assigned by the MEPM according to the identity carried in the registration response message; optionally, when the registration response message also carries access control data, the LEPM can also determine that there is no need to perform identity again within the preset time period. verification.

The embodiment of the present application also provides a possible implementation. This embodiment is similar to the embodiment shown in FIG. 4, except that step 403 is different. In this embodiment, step 403 may not be executed, and step 404 may be executed directly. , And in this step 404, the MEPM directly sends a registration response message to the LEPM through the access address, that is, the MEPM does not need to authenticate the LEPM, and directly assigns the corresponding identifier to the LEPM.

Therefore, it can be known from the embodiment shown in FIG. 4 that the MEPM determines the geographic location of each LEPM and assigns a corresponding identifier to each LEPM.

The location information of the target mobile edge host can be multiple, as shown below:

Manner 1: Geographic location information of the target mobile edge host. The geographic location information may include specific location information such as "province, city, district/county, street, community/computer room", etc. The application instantiation request carries the geographic location information of the target mobile edge host, and then the MEPM determines the corresponding LEPM according to the geographic location information provided during LEPM registration, and the LEPM deploys the MEC application on the target mobile edge host.

Method 2: The subnet attribute information of the target mobile edge host. For example, the subnet attribute information includes the IP address range of a network segment, which can be specifically identified by an IP address and subnet mask in the network segment, such as 192.168 .0.1/255.255.255.0. That is, the application instantiation request carries the IP address and subnet mask of the target mobile edge host, and MEPM matches the IP address and subnet mask of the target mobile edge host with the IP address and subnet mask provided during LEPM registration. The corresponding LEPM is determined, and the LEPM deploys the MEC application on the target mobile edge host.

It should be noted that when the application instantiation command does not carry the location information of the target mobile edge host, the MEPM selects a LEPM from the LEPMs it manages to deploy the MEC application. The specific selection strategy includes random selection or selection of LEPM with the least number of currently deployed applications, etc. The specific selection strategy is not limited here.

303. MEPM sends the application instantiation command to LEPM.

Wherein, the application instantiation command carries information of the MEC application, for example, the size of the resources that the MEC application needs to apply for. After the MEPM determines the corresponding LEPM, it sends an application instantiation command to the LEPM to instruct the LEPM to perform the management operation of the application instantiation on its behalf.

304. LEPM sends a resource request message to VIM.

Among them, the resource request message is used to request the creation of an MEC application and resources for running the MEC application.
