Problems solved by technology

Because the traditional DCN network is based on optical signal transmission on the communication line, and the switching nodes must be based on electrical signals when exchanging messages, so each hop switch on the transmission path must perform optical signal to electrical signal and then optical signal conversion, which also leads to DCN network Problems such as high energy consumption, high construction costs, high packet E2E transmission delay, and limited switching port bandwidth limited by electrical signal processing capabilities

Embodiment Construction

[0046] The present application embodiment will be described below in connection with the drawings in the present application embodiment.

[0047] Such as figure 1 As shown, most of the traditional data center uses a fat tree structure, the network structure uses a tree three-layer structure, and the network is divided according to the core layer, the aggregation layer, and the edge access layer. Multiple servers are loaded in each rack, which is connected by a rack top switch (Tor switch), and the TOR switch is interconnected as an edge access switch with a gathering layer switch (LEAF switch) to form a POD (Point of Delivery). The cluster (hereinafter referred to as a business cluster in the embodiment), in the POD cluster, in order to improve the reliability of the link, the edge switch and the aggregation switch can cross all interconnect. The three-layer backbone switches (such as SPINE switches) are used to provide an external access function, as well as interconnection betwe...

Abstract

An embodiment of the invention discloses a communication method, device and system in a data center, provides novel photoelectric hybrid routing data center networking architecture, provides a distributed source routing technology based on a server in the data center, and shares the load of a switch. Besides, in the data center networking architecture, optical cross equipment is provided to be interconnected with an access switch or a convergence switch, and different routing strategies are carried out for different types of data streams, so that the network transmission efficiency is improved, and the energy consumption of the data center is reduced.

Description

[0001] The present application claims priority to China's patent application filed on August 17, 2020, and the present invention, the present invention, which is incorporated herein by reference. . Technical field [0002] The present invention generally relates to communication techniques, and more particularly to a communication method, apparatus, and system in a data center. Background technique [0003] In the traditional data center network of the tradition, the Fat-Tree is generally used, and the end side server is connected to the TOR (TOP OF RACK) switch, Tor switch, and Leaf, Spine, Core switch can form a data center network (Data Center Network, DCN) that is up to several million nodes in accordance with a certain convergence than the interconnection. [0004] Traditional DCN network switches to process the network packets carried by the electrical signal, support packet-level exchange and routing, and support high-level features such as packets on the switch and traffic...
