The following detailed description is given with reference to preferred embodiments of the present invention.
The preferred embodiment of the present invention provides a method for ensuring application migration on demand through interaction between edge computing nodes after the edge computing node network is successfully deployed, and fig. 5 is a schematic diagram of application instance mobility requirements on an MEC caused by movement of a UE between sites according to the preferred embodiment of the present invention, as shown in fig. 5.
After the edge computing node identifies the adjacent edge computing node and establishes the adjacent relation, the topology information of the edge computing node network is locally stored.
The mobility requirements of the applications are usually due to the movement of the terminal itself. Another scenario is that mobility requirements may also arise due to capacity problems or certain functionality problems of the ECN nodes themselves.
When the ECN identifies the mobility requirement of the application, it may make a mobility decision through an edge computing Node management Entity (ECNO). However, when the ECNO is out of service for some reasons or the user configures the mobility processing without the ECNO decision, the ECN can complete the processing procedure of applying the mobility through the network topology information of the edge computing node stored by the ECN.
Specifically, the ECN generates a mobility cause, a mobility target node, through a mobility requirement generation mechanism.
The ECN finds candidate target ECNs in the network topology information of the edge computing node by checking the mobility target node.
The ECN judges the method for initiating the mobility action by checking the mobility reason, the state information of the ECN and the information of the candidate ECN. Generally, there are three mobility handling approaches that can be considered: application instance migration, application instance context migration, and service bridge creation. Examples include instance data, context, among others. Example data is data and files necessary in application business logic. The context includes screening settings, routing settings, stack information used by the application instance. The following are explained separately:
application instance migration refers to the migration of an application instance, including an application instance, context, as a whole from a source ECN node (ECN1) to a target ECN node (ECN 2). The process of migration includes checking the creation condition of the application instance on ECN2, transferring the application data and context to ECN2, and creating the application instance and setting the context on ECN 2. When the instance on ECN2 runs successfully, ECN2 notifies ECN1 that the application instance migration successfully ends. If the migration process fails, the target ECN may be reselected or the application instance may be migrated to ECN2 again or released, depending on the user-configured policy.
Application instance context migration refers to the application instance and context on the source ECN (ECN1) remaining intact, migrating only the necessary context information and business necessary state information to the target ECN (ECN 2). After the application instance copy on ECN2 successfully launches, ECN2 notifies ECN1 that the application instance context migration successfully ends. How applications on ECN1 and ECN2 collaborate is what applications need to consider. If the migration process fails, the target ECN may be reselected or migrated again to ECN2 or the migration may be aborted, depending on the user-configured policy.
The service bridge approach refers to the lack of certain requirements for the application instance to run on the target ECN, such as the inability of the necessary service to start. In this case, a data bridge between the application instance on the source ECN and the traffic data on the target ECN needs to be established between the target ECN and the source ECN. The data bridge can realize bidirectional communication through simple routing setting, and can also achieve the aim through other methods. If the migration process fails, the target ECN may be reselected or migrated again to ECN2 or the migration may be aborted, depending on the user-configured policy.
FIG. 6 is a flowchart of an application instance migration process, according to the preferred embodiment of the present invention, as shown in FIG. 6, the steps are as follows:
in step S601, the ECN1 determines to initiate migration to the ECN2 by using the application instance migration method according to the generated application instance mobility requirement and the queried adjacent ECN (ECN2) information.
Step S602, ECN1 initiates application instance migration to ECN 2. The information comprises the migration type, the migration reason, application instance data and context information.
In step S603, the ECN2 checks whether the condition is satisfied after receiving the application instance migration information. And then completing the creation of the application instance, setting the context and the data and running the application instance. And then sends a migration success message to ECN 1.
