810-046015-010 接口板模块

为方便理解网络设备内部的各个功能模块，以810-046015-010为例讲解典 型网络设备的构架:

●主控板(MPU，Main Processing Unit):负责整个系统的控制平面。

●交换网板(SFU, Switch Fabric Unit):负责整个系统的数据平面。数据平面提供高速无阻塞数据通道，实现各 个业务模块之间的业务交换功能。

●接口板(LPU, Line Processing Unit): 线路处理单元是物理设备上用于提供数据转发功能的模块，提供不同速率的光口、电口。

●交换网板、接口板上都有自己的管理芯片，与主控板共同组成整个设备的控制管理平面

主控板提供了整个系统的控制平面和管理平面。

交换网板提供整个系统的数据平面。接口板、主控板之间通过交换网板完成通信。

To facilitate the understanding of various functional modules within network devices, take 810-046015-010 as an example to explain the architecture of typical network devices:

Main Processing Unit (MPU): responsible for the control plane of the entire system.

Switch Fabric Unit (SFU): responsible for the data plane of the entire system. The data plane provides high-speed and non blocking data channels, enabling business exchange between various business modules.

LPU (Line Processing Unit): A line processing unit is a module on a physical device that provides data forwarding function, providing optical and electrical ports at different rates.

Each switch network board and interface board has its own management chip, which, together with the main control board, forms the control and management plane of the entire device

The main control board provides the control plane and management plane of the entire system.

The exchange network board provides the data plane of the entire system. The communication between the interface board and the main control board is completed through the exchange network board.
