Hello. The upstream data flow is going out from the board. it is the information that you send to another host or another equipment into the network. Downstream data flow is the data coming to the boards, the board receive data from another node in the network.

Hi,


The control plane, functioning as the nerve center, integrates control and management functions and uses buses to control system units.

The control plane consists of control units on MPUs and those on other boards. Each MPU is comprised of the following three functional units:

  • System management and control unit and system clock unit: work on the control plane.

  • System maintenance unit: works on the monitoring plane. For more information, see section "Signal Flow on the Monitoring Plane" in this document.

MPU units and board units communicate through system buses and the SFU.


The control plane processes the following signal flows:

  • Singling signal flow and operation and maintenance signal flow: processed by the system management and control unit.

  • Clock signal flow: processed by the system clock unit.
