Connection architecture and method of core router and edge router based on unidirectional transmission

Abstract

The invention discloses a connection architecture and method of a core router and an edge router based on one-way transmission, and belongs to the technical field of routing. The router comprises a core router and an edge router; the core router comprises a router host, a connecting panel, a plurality of connecting ports and a pair of power interfaces, the connecting ports are distributed on the surface of the connecting panel at equal intervals, the connecting panel is embedded in the front surface of the router host, the router host is an Soc system following an AXI bus protocol, and the input ends of the connecting ports are electrically connected with the output end of the router host; the edge router comprises a WAN access port and a plurality of LAN output ports, the edge router is in wired connection with the connection port through the LAN output ports, and the connection architecture can avoid network signal data packet loss occurring during output of the core router and the edge router according to a transmission mode of a one-way channel; therefore, the applicability and the practicability of the connection framework are improved.

Description

Technical field [0001] The present invention relates to the field of routing technology, in particular, a connection architecture and method of a core router and an edge router based on one-way transmission. Background technique [0002] The core router is also known as the backbone router, which is a router located in the center of the network. Routers at the network edge are called access routers, core routers and edge routers are relatively concepts, they are routers, but there are different sizes and capacities, a layer The core router is the edge router of another layer. It is a router that encompasses the computer host in the network. In the Internet, located in the network core, it is mainly used for data packet selection and forwarding, generally have large throughput routers; [0003] The networking mode of the existing core router and the edge router typically follows the principle of fiber linking, in the transmission, the transfer of data in the forwarding process is ...

AI Technical Summary

Problems solved by technology

[0003] The existing core routers and edge routers usually follow the principle of optical fiber linking. During the access and forwarding process, the data transmission is sequentially forwarded by the network terminal, core router, and edge router to the network signal transceiver. In the process of transmission and forwarding, the signal is easily interfered by two-way sending and receiving data, which causes network forwarding delay and affects the actual network signal forwarding efficiency
