LAM 810-046015-010 可编程控制器模块

为方便理解网络设备内部的各个功能模块，以810-04601 5-010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。  

1.控制平面完成系统的协议处理、业务处理、路由运算、转发控制、 业务调度、流量统计、系统安全等功能。 

 2.管理平面完成系统的运行状态监控、环境监控、日志和告警信息处理、系统加载、 系统升级等功能。  交换网板  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。

In order to facilitate the understanding of each function module inside the network device, 810-04601-5-010 is used as an example to explain the architecture of typical network devices:

● Main Processing Unit (MPU): is 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 non-blocking data channels and implements service exchange between service modules.

● Interface board (LPU): A Line Processing Unit (LPU) is a module on a physical device that provides data forwarding functions and provides optical and electrical interfaces at different rates.

● The switch board and interface board have their own management chips, which together with the main control board form the control management plane of the entire device. The main control board provides the control plane and management plane of the entire system.

1. The control plane performs functions such as protocol processing, service processing, route calculation, forwarding control, service scheduling, traffic statistics, and system security.

2. The management plane performs functions such as system running status monitoring, environment monitoring, log and alarm processing, system loading, and system upgrade. Switching SFU The switching SFU provides the data plane for the entire system. The interface board and the main control board communicate with each other through the switching network board.
