Problems solved by technology

In the current cloud-edge-end integration platform, because the cloud and the edge are not on the same network plane, the user's request for service access in the cloud will fail.
Moreover, the current cloud-edge-device integration cloud-device communication only realizes the part of the control flow through the websocket protocol
[0004] At present, in the cloud edge system, if the edge gateway is in the internal network environment and can only access the public network in one direction, in this scenario, users cannot access the services deployed on the edge side in the cloud. The purpose of this invention is to solve the problem in the cloud edge system , the communication problem of cloud-to-edge user service access, by setting EdgeGateway in the cloud, support user-defined Loadbalance strategy, based on QUIC protocol communication to improve the speed of cloud-to-device communication and the performance in a weak network environment

Embodiment Construction

[0040] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] The present invention is a design based on the QUIC protocol to realize cloud access to edge services. Since the network environment of edge nodes is often not very stable, the QUIC protocol has better performance than websocket in a weak network environment and avoids head-of-line blocking multiplexing. Use has higher speed than websocket. Structural composition in the design of the present invention comprises:

[0042] Tunnel server: saves the QUIC connection entity that communicates with the IP and hostname of the edge node and the edge node corresponding to the IP and hostname.

[0043] EdgeGateway: Receive the data request sent by the user, and generate a SessionID, responsible for executing the reverse proxy, doing load balancing, parsing the specific host IP (intranet IP) from the Endpoints in the Ready state, and forwarding the request to...

Abstract

The invention belongs to the field of cloud computing and edge computing, and discloses a cloud edge service access method and system based on a QUIC protocol. According to the system, an edge gateway and a tunnel server are arranged at the cloud, wherein the edge gateway supports a user-defined load balancing strategy, each edge node is provided with a service flow component, and therefore, a QUIC connection is created when the edge node is started, thereby creating a data channel for accessing the edge end service from the cloud. According to the method, the function of accessing the edge service by the cloud is realized, a user in a public network can access the edge service in an intranet through the cloud, the method still has good performance in an edge side weak network environment, the loading service performance can be effectively improved, and the network stability is improved.

Description

technical field [0001] The invention belongs to the field of cloud computing and edge computing, and in particular relates to a method and system for cloud accessing edge services based on the QUIC protocol. Background technique [0002] With the development of technologies such as containers, kubernetes, and the Internet of Things, the data generated at the edge of the network is growing rapidly, but the transmission of massive data to the cloud center is a test for the bandwidth and delay of the network, and the privacy of user data cannot be guaranteed. In order to solve these problems, edge computing has been developed. Most deployment and application scenarios of edge computing require collaboration between the edge side and the central cloud, and cloud-side collaboration, including resource collaboration, application collaboration, data collaboration, and intelligent collaboration. [0003] With the development of cloud computing and microservices, the scalability, up...
