Edge cloud message forwarding method and system, network message forwarding method and system

Abstract

The invention belongs to the technical field of networks, and in particular relates to a method and system for forwarding edge cloud messages, and a method and system for forwarding network messages. The method includes: presetting an edge forwarding table; an edge device initiates an application requesting network message; a switch matches a flow table after receiving the application requesting network message, and uploads it to a controller; the controller parses the message and matches the edge forwarding table source IP, destination IP, and destination port; if the match is successful, the destination IP and destination port in the flow table will be modified, and the network packet and the corresponding updated flow table will be sent to the switch; the switch will respond to the received network packet. Forward to the edge cloud according to the update flow table; the edge cloud node performs tasks such as computing after receiving the request network packet, and returns a response packet, which is forwarded to the switch through the network; the switch updates the flow table according to the previous controller. , forwarding from the response port. This packet forwarding method greatly improves the bandwidth and delay of packet forwarding.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to an edge cloud message forwarding method, an edge cloud message forwarding system, a network message forwarding method, and a network message forwarding system. Background technique [0002] In a cloud computing environment with a centralized architecture, all requests and data from edge users will be sent to the centralized cloud computing center (cloud data center), where the computing and storage of big data is performed in a centralized manner. With the rapid development of technologies such as 4K video, VR / AR, and 5G, user-side edge devices are showing explosive growth. Faced with a large number of edge access devices, higher requirements are placed on network bandwidth and latency. Faced with the access of a large number of edge devices, it is difficult to meet the requests of edge users, which brings a series of problems such as network congestion and low user ...

Problems solved by technology

This method usually requires manual configuration of the DNS server in each area, and the granularity is relatively coarse, so flexible scheduling based on applications cannot be realized.
