The inventor finds that with the development of security technology, in a security scene of edge computing, when the service capability of an edge device needs to be expanded, because an edge node does not support a cluster generally and has weak extension capability, it is necessary to continue purchasing devices with the same capability to access an edge network to solve the requirement, but adding devices with the same magnitude to expand specific capability easily causes resource redundancy, increases the complexity of a system, is inconvenient to implement, and has high cost. Therefore, the inventor proposes a method and a system for extending the capability of an edge node, wherein an extension box is controlled to receive control information for extending the capability of the edge node by accessing the extension box to an edge network, and the control information includes: the method comprises the steps of downloading information of capacity resources sent by a central cloud and scheduling information sent by edge nodes, completing communication authentication with the edge nodes according to control information, processing tasks of the edge nodes by using resources of an extension box, well realizing capacity extension of the edge nodes, and having the advantages of convenience in implementation, low cost, easiness in development and maintenance, high flexibility, low complexity and high implementability.
As shown in fig. 1, the method for extending capability of an edge node in this embodiment includes:
s1: accessing an extension box to an edge network, the edge network comprising: one or more edge nodes; the expansion box is a lightweight box, when the capacity of the edge node in the edge network is insufficient, the resource of the expansion box can be utilized to assist in processing the task of the edge node, the capacity expansion of the edge node is realized, no edge node needs to be newly added, and the cost is low. For example: when the capability of the edge node does not meet the current service requirement or the strength of the current processing task of the edge node exceeds a preset processing strength threshold value, the expansion box is accessed to the edge network, the capacity expansion is carried out on the edge node by utilizing the expansion box, the situation that the capability of a single edge node is not enough by repeatedly purchasing edge equipment with complete service capability is avoided, the cost is effectively saved, and the implementation is convenient. The extension box in this embodiment is a lightweight box with a hardware bottom layer for capability extension, which may be added to the edge network by a user after deploying a service or task beyond the capability, or may be a box existing in the edge network environment.

For example: when the edge network does not have an expansion box meeting the corresponding requirement, the expansion box is controlled to receive capacity resource downloading information sent by a central cloud end, capacity configuration of the expansion box is carried out, after configuration is completed, the control central cloud end generates scheduling information of the expansion box and synchronizes the scheduling information to the corresponding expansion box, an edge node receives the scheduling information of the corresponding expansion box sent by the central cloud end and sends the scheduling information to the corresponding expansion box for communication authentication, the expansion box receives the scheduling information sent by the edge node, communication authentication of the edge node and the expansion box is completed, the resources of the expansion box are utilized to process tasks of the edge node and carry out capacity expansion on the edge node, safety and stability of communication connection between the edge node and the expansion box are effectively improved, and repeated purchase of edge equipment with complete service capacity is avoided to make up for the capacity deficiency of a single edge node, effectively saves the cost and is more convenient to implement.
In order to increase the flexibility of the capability extension, the inventors propose that the extension box comprises one or more tasks that handle the edge nodes using the resources of one or more of the extension boxes.

For example: when the capability of the edge node does not meet the current service requirement or the strength of the current processing task of the edge node exceeds a preset processing strength threshold value, the edge node is controlled to send a capability expansion request to the central cloud end, capability expansion is carried out on the edge node, the situation that the capability of a single edge node is insufficient by repeatedly purchasing edge equipment with complete service capability is avoided, the cost is effectively saved, and the implementation is convenient.
S203: and the central cloud end checks whether an expansion box meeting the corresponding requirement exists according to the capacity expansion request.

S304: and the expansion box transmits the processing result to the corresponding edge node to complete the capacity expansion of the edge node. And the expansion box is controlled to transmit the processing result to the corresponding edge node, so that the capability expansion of the edge node is better realized.
It can be understood that, in order to improve the security of information interaction between the edge node and the expansion box, in the information interaction process between the edge node and the expansion box, when the edge node sends a request or a task to the corresponding expansion box, the expansion box checks the scheduling information sent from the edge node according to the request or the task, and after the check is completed, the expansion box is controlled to process the corresponding task, so as to improve the security and the stability of information interaction between the edge node and the expansion box.
As shown in fig. 5, in order to improve the stability and the real-time performance of communication between an edge node and an extension box, the inventor proposes that, after communication authentication is completed, or after an edge node sends task information to be processed to an extension box, a communication link between the edge node and the extension box is kept alive according to a preset retransmission mechanism, and the keep-alive step includes:
