The NE40E consists of the following major boards: Switch and Route Processing Unit (SRU),
Switch Fabric Unit (SFU), service board and abundant Line Processing Units (LPUs). Redundancy
design is adopted for the key parts such as SRUs, SFUs, fans and power supplies to raise the
reliability of the entire system. The interface types of LPUs include FE, GE, 10GE, POS, CPOS,
ATM and RPR.
The logical architecture of the NE40E includes three planes: data plane, control and management
plane, and monitoring plane. The three planes provide the following functions:
Logical architecture of the NE40E
z The data plane completes high-speed data packet processing and internal non-blocking
switching, including packet encapsulation/decapsulation, IPv4/MPLS forwarding processing,
QoS and packet scheduling, internal high speed switching and various statistics.
z The control and management plane completes system control and management functions. It is
the nerve center of the entire system. The control and management unit completes functions
such as protocol and signaling processing, system status configuration and maintenance
management as well as system status reporting and control.
z The monitoring plane independently completes system environment monitoring, including
voltage detection, system power on/off control, temperature detection and fan control to
ensure the safe and stable operation of the system. It isolates the fault in time when a unit is
faulty, thus guaranteeing the normal operation of the other system components.
