Problems solved by technology

The disadvantage of this connection method is that if the number of node devices in the cabinet is large, then the top-of-rack switch needs to have enough ports to connect to each node device. Occupies more resources of the top-of-rack switch
Moreover, if the ports of the top-of-rack switch are insufficient, some node devices in the cabinet may not be able to connect to the network

Abstract

The invention discloses a node system and is used for solving the technical problem that each node device in a cabinet needs to be connected with a top-of-rack switch, so the hardware demand for the top-of-rack switch is relatively high. The system comprises multiple node devices, wherein at least one node device in the multiple node devices are master node devices, the other node devices are slave node devices, each master node device is connected with a switching device, each master node device controls communication between at least one slave node device and the switching device. The invention also discloses a data packet transmission method and corresponding devices.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data packet transmission method, device and system. Background technique [0002] In the prior art, multiple node devices (such as servers, and of course other node devices) are often placed in a cabinet to form a cluster, and all node devices in a cabinet are connected to a switch corresponding to the cabinet , because this switch is usually set on the top of the cabinet, it is generally called a top-of-rack switch. The top-of-rack switch is connected to the core switch to connect the cabinet to the network. [0003] At present, each node device in a cabinet is independent of each other, each node device is connected to a top-of-rack switch, and communicates with the network through the top-of-rack switch. The disadvantage of this connection method is that if the number of node devices in the cabinet is large, then the top-of-rack switch needs to have enough po...
