Through the steps, an adjacency relation can be established with a second ECN according to the received network structure information of the second ECN from the ECNO, wherein the number of the second ECN can be one or more, and when the adjacency relation is established, an adjacency relation can be established with part of the second ECN (namely, part of the one or more ECNs) according to the network structure information of the second ECN, so that the self-networking is realized. The problem that the network is difficult to maintain due to the fact that ECN networking cannot be effectively achieved in the related technology is solved, and the effects of achieving ECN networking, reducing ECN network engineering difficulty and reducing maintenance cost are achieved.

The problem that the network is difficult to maintain due to the fact that ECN networking cannot be effectively achieved in the related technology is solved, and the effects of achieving ECN networking, reducing ECN network engineering difficulty and reducing maintenance cost are achieved.
In an optional embodiment, after establishing a link with the first ECN according to the first link establishment request and sending the response message to the first ECN, the method further includes: receiving updated ECN network structure information sent by a first ECN, wherein the updated ECN network structure information comprises adjacency relation information, added in the network structure information of a second ECN, of the first ECN and the second ECN; judging whether adjacent relation updating information of a second ECN and a first ECN from the second ECN is received or not; and if the judgment result is yes, updating the ECN network structure information stored in the ECNO according to the updated ECN network structure information.

As can be seen from the foregoing embodiments, to achieve the foregoing object, an ad hoc networking method for an edge computing node provided in an embodiment of the present invention includes: the edge computing node needs to store routing and security authentication information to ECNO by pre-configuration when being deployed. After the edge computing node ECN1 finishes project deployment, a link is automatically established with an edge computing node management entity and the network information of the existing edge computing node is received. According to the network information of the existing edge computing nodes, the ECN1 searches the adjacent edge computing nodes and reports the connection relation to the ECNO. Other ECNs that have been linked to ECN1 also update their relationship to ECN1 and report to ECNO. The ECNO updates and maintains the edge compute node network information for subsequent use.
The invention is illustrated below with reference to specific examples:
fig. 4 is a flow diagram of establishing a link with an ECNO and obtaining edge computing network node information after deployment of ECN1, according to an embodiment of the present invention. As shown in fig. 4, the process includes the following steps:
step S401: ECN1 initiates a link establishment request to the ECNO.
Step S402: the ECNO processes the link establishment request, performs security authentication and responds to the link establishment request, and when responding to the link establishment request, the ECN network structure information (corresponding to the second ECN network structure information) can be carried or the ECN network structure information can be sent separately later. In this embodiment, the ECNO may issue ECN network structure information that may become an adjacent ECN with the ECN1 or issue all ECN network structure information according to the deployment information of the ECN 1.
Step S403: upon receipt of the network configuration information, ECN1 locally retains the original network configuration information and creates new network configuration information for subsequent addition of adjacency information. And then sends a confirmation message to the ECNO.
Fig. 5 is a flowchart of establishing a link with an adjacent ECN and updating to an ECNO after the ECN1 is deployed, where the flowchart includes the following steps, as shown in fig. 5, according to an embodiment of the present invention:
step S501: ECN1 (corresponding to the first ECN) sends a link establishment request to a known ECN according to ECN network structure information issued by ECNO;
step S502: the adjacent ECN node (corresponding to the second ECN), such as the ECN2, retains the relevant information of the ECN1 and replies a response after receiving the link establishment request;
step S503: adding ECN2 information in the local ECN network structure information after the ECN1 receives the chain establishment response of the ECN 2;
step S504: the ECN1 completes the link establishment attempt process of all ECN nodes according to the ECN network structure information of the ECNO response. And finally sending the updated local ECN network structure information to the ECNO through an update message.
Fig. 6 is a flowchart of an ECN information update procedure adjacent to ECN1 and an update of the ECNO final network structure information according to an embodiment of the present invention, and as shown in fig. 6, the flowchart includes the following steps:
step S601: ECN adjacent to ECN1 sends updated adjacent relation update message of local node to ECNO;
step S602: after ECNO receives the adjacent node updating relationship message, checking whether the adjacent relationship updating message of the two adjacent relationship sides is received. If so, the adjacency holds. And updating the ECN network structure information.
After the above steps are completed, the edge compute node is ready to handle mobility. When an application must move out of the source edge compute node (assumed ECN1) due to terminal movement or other reasons, ECN1 looks up the adjacency information it holds and sends a move request to the ECNO.
There are three possible treatment outcomes for ECNO depending on the situation:
1) the application needs to move from ECN1 to ECN2, ECN1 and ECN2 process the moving process after obtaining the moving instruction of ECNO (the moving instruction obtained by ECN1 corresponds to the first moving instruction, and the moving instruction obtained by ECN2 corresponds to the second moving instruction), after the moving instruction is processed, the application on ECN1 is deleted, and a new application is created and provided with service on ECN 2;
2) the application needs to transfer partial information from ECN1 (assuming that the information that needs to be transferred is M) to ECN 2. after the instruction is processed, the same application exists on ECN1 and ECN2, where M remains consistent on both sides;
3) there is no way on ECN2 to create applications, therefore, ECN2 and ECN1 need to create routing bridges to ensure that data on ECN2 can interact with applications on ECN 1.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
