Signal Flow on the Monitoring Plane

Signal Flow on the Monitoring Plane

The monitoring plane monitors the system environment. If a fault occurs on a unit, the monitoring plane isolates the fault to prevent it from affecting other units on the device. The control and monitoring planes are working together to support the operation and maintenance of a device and improve performance stability.

Both the control plane and monitoring plane consist of the system operation and maintenance unit and the monitoring units on LPUs and an SFU. Inter-board communication is implemented using the system backplane.

Figure 6-4 illustrates the principles of signal flow transmission on the monitoring plane.

Figure 6-4 Signal flow transmission on the monitoring plane

The monitoring plane, like the control plane, supports bidirectional signal flows.
  • Board-to-LPU signal flow: implements monitoring. The system maintenance unit on each LPU uses a MonitorBus to collect operating information on system units and generates control information based on the unit-specific operating status.
  • LPU-to-board signal flow: implements control. An LPU delivers control information to modules to monitor board information, such as the installation and operating status and fan speed. The LPU also loads a bus to locally or remotely test or upgrade system units.
