Abstract

The invention discloses a network device, the network device includes: at least one management board, the management board includes: a first central processing unit (CPU) module, a first serial port module and a first multiplexer, the The first multiplexer is respectively connected to the first CPU module and the first serial port module; a plurality of service boards, the service boards include: a second CPU module, a second serial port module and a second multiplexer The second multiplexer is connected to the second CPU module and the second serial port module respectively; the backplane, each of the management boards and each of the service boards is connected to the backplane; wherein , the backplane includes: a serial port shared signal line, the serial port shared signal line is connected to the first multiplexer on each of the management boards and the second multiplexer on each of the service boards. The embodiments of the present invention reduce backplane wiring, and can reduce the complexity of backplane wiring.

Description

technical field [0001] The invention relates to the field of network control, in particular to a network device. Background technique [0002] With the rapid development of cloud computing and virtualization technologies, and the integration of data center services, higher requirements are placed on the performance, functions, and reliability of network devices such as switches and servers. For example, in order to support different network types, a modular switch with good scalability is used. The slots of the modular switch can be equipped with management boards and service boards according to user needs. Among them, the service board is also called the service card, and the network packets are output from the corresponding terminals of the service board after passing through the service board and the switching module in the modular switch; the management board is used to provide the management and control functions of the switch and the data plane The protocol processing...
