Logical Architecture

Logical Architecture

The logical architecture of the NE40E consists of three planes: data plane, control and management plane, and monitoring plane, as shown in Figure 6-2.

Figure 6-2 Logical architecture
  • The data plane is responsible for high-speed processing and congestion-free switching of data packets. It encapsulates and decapsulates packets, forwards IPv4/IPv6/MPLS packets, performs QoS as well as scheduling and internal high-speed switching, and collects statistics.

  • The control and management plane provides all control and management functions for the system and is the core of the entire system. Control and management units process protocols and signals and configure, manage, report, and control system status.

  • The monitoring plane monitors the ambient environment to ensure the secure and stable operation of the system. It detects voltage levels, controls system power-on and power-off, monitors the temperature, and controls fan modules. If a unit fails, the monitoring plane isolates the faulty unit promptly so that the other units remain unaffected.
