Description
810-073479-215 LAM Interface Board module This section uses 810-073479-215 as an example to explain the architecture of a typical network device.
Main Processing Unit (MPUs) : The main processing unit (MPUs) is the control plane of the entire system.
Switch Fabric Unit (SFU) : is responsible for the data plane of the entire system. The data plane provides
high-speed non-blocking data channels to implement service switching between service modules.
Interface board (LPU) : A Line Processing Unit (LPU) is a module used to forward data on a physical device.
It provides optical and electrical interfaces 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
810-073479-215 The main control board provides the control plane and management plane for the entire system.
Control plane 810-073479-215 Implements protocol processing, service processing, route calculation, forwarding control, service scheduling, traffic statistics, and system security.
The management plane monitors system running status, monitors the environment, processes logs and alarms, loads the system, and upgrades the system.
Each module of a framed device is divided into different boards. Boards communicate with each other through internal connections of the framed device.
These modules are integrated into the box, and they also communicate with each other through internal connections.
Interface boards are connected to each other through the switching network board. Communication between interface boards is forwarded through the switching network board.
