Abstract

The invention discloses a data center network system and a signal transmission system. Each switch is provided with a hub device in communication connection with the switch itself, the hub devices and the switches form a star network topology structure, and in comparison with a mesh network topology structure, wiring among devices in the star network topology structure is less, the network wiring amount can be effectively reduced, and the workload of subsequent network maintenance is reduced; signals outputted by a source server pass through a source switch in communication connection with the source server, a hub device, and a target switch in communication connection with a target server sequentially and further reach the target server, all signals are forwarded through the hub devices, the signal forwarding levels are few, and thus, the network structure flattening of the data center network system is realized, energy consumption caused by a core layer device and a convergence layer device is reduced, and the system energy consumption and the device maintenance cost are effectively reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data center network system and a signal transmission system. Background technique [0002] The data center network is a network applied to the data center, which is mainly composed of a large number of layer 2 access devices and a small number of layer 3 devices. refer to figure 1 As shown in FIG. 2 , the existing data center network is a hierarchical aggregation structure, which usually includes three layers: an access layer, an aggregation layer, and a core layer. [0003] refer to figure 1 As shown, in the hierarchical structure of hierarchical convergence, when server 1 needs to send a signal to server 2, since server 1 and server 2 belong to different access layer devices, the access layer device 1 corresponding to server 1 needs to send all The above signal is sent to the access layer device 1, and the access layer device 1 needs to send the signal to the conver...
