Application access method, cloud proxy component, node proxy component, device and medium

An application access method, applied to a node proxy component, wherein the application access method comprises:

• during node registration of a local node, performing node discovery on each edge node in a current cluster to obtain a node discovery result, to determine whether there is a node located in a same local area network as a newly registered edge node;
• wherein the current cluster comprises edge nodes, the newly registered edge node is an edge node newly registered to the current cluster, the newly registered edge node and an edge node that are located in the same local area network are capable to access each other, the newly registered edge nodes and an edge node that are not located in the same local area network are unable to be directly connected;
• sending the node discovery result to a cloud proxy component, so that the cloud proxy component updates a global routing table based on the node discovery result, wherein in response to the node discovery result indicating that no node located in the same local area network as the newly registered edge node is discovered, the cloud proxy component performs a user datagram protocol (UDP) hole punching operation between a local area network where a newly registered edge node is located and a current existing local area network to obtain an intercommunication relationship between local area networks, and updates the global routing table based on the intercommunication relationship;
• in response to the node discovery result indicating that a node located in the same local area network as the newly registered edge node is successfully discovered, the cloud proxy component associates node information of the newly registered edge node with target local area network information to update the global routing table, the target local area network information is local area network information of a local area network where a successfully discovered node is located;
• and
• acquiring the global routing table issued by the cloud proxy component, and forwarding an application access flow based on the global routing table to realize application access;
• wherein the acquiring the global routing table issued by the cloud proxy component, and forwarding the application access flow based on the global routing table to realize application access comprises:
• receiving an application access flow sent by a first local application to a second application;
• selecting an application forwarding mode based on the global routing table;
• and sending the application access flow sent by the first local application to the second application through the application forwarding mode.

An electronic device, comprising a processor and a memory, wherein

• the memory is configured to store a computer program;
• and
• the processor is configured to, when executing the computer program, implement operations comprising:
• acquiring a node discovery result, wherein a current cluster comprises edge nodes, a newly registered edge node is an edge node newly registered to the current cluster, the newly registered edge node and an edge node that are located in a same local area network are capable to access each other, the newly registered edge node and an edge node that are not located in the same local area network are unable to be directly connected;
• the node discovery result is a node discovery result obtained by a node proxy component in the newly registered edge node to perform node discovery on each edge node in the current cluster, to determine whether there is a node located in the same local area network as the newly registered edge node;
• in response to the node discovery result indicating that no node located in the same local area network as the newly registered edge node is discovered, performing a user datagram protocol (UDP) hole punching operation between a local area network where the newly registered edge node is located and a current existing local area network to obtain an intercommunication relationship between local area networks, and updating a global routing table based on the intercommunication relationship;
• in response to the node discovery result indicating that a node located in the same local area network as the newly registered edge node is successfully discovered, associating node information of the newly registered edge node with target local area network information to update the global routing table, wherein the target local area network information is local area network information of a local area network where a successfully discovered node is located;
• and
• issuing the global routing table to a node proxy component in each edge node of the edge nodes in the current cluster, so that the node proxy component in each edge node forwards an application access flow based on the global routing table to realize application access;
• wherein before the operation of acquiring the node discovery result, the operations further comprise:
• issuing a cluster node list to the node proxy component in the newly registered edge node, so that the node proxy component in the newly registered edge node performs node discovery on each edge node in the current cluster based on the cluster node list, to obtain the node discovery result.
