ZXR10 ZSR V2 Series Router Product Description
72 ZTE Confidential & Proprietary
The ZXR10 ZSR V2 has independent forwarding plane and control plane. The system
focuses on the management and packet forwarding unit (MPFU), and uses the
backplane to communmicate with other components. The multicore engine on the MPFU
contains forwarding core and control core as per different working contents. The
forwarding core and other system components compose a logical forwarding plane to
implement message forwarding and service processing. The control core and other
system components make of a logical control plane, which is used to implement routing
protocol interaction, routing calculation, system amanagement and control message
synchronization. The system archigtecture with the independent forwarding and control
planes enables minimum mutual influence caused in extending the services and
performance of the two planes. In this way, the system is more flexible.
The modular power supply unit and fan unit of the ZXR10 ZSR V2 can connect with the
high-speed backplane in the manner of the chassis, so that the entire device can be
cable-free. For the power supply unit, the ZXR10 ZSR V2 provides AC and DC power
supply modes.
4.2.2 The Working Principle of the Hardware System
The ZXR10 ZSR V2 uses independent control forwarding and control planes, and the two
planes are protected standby. The data packets experience the PIU physical layer chip
processing and frame resolution first. The ordinary services are sent directly to the MPFU.
Then the traffic management unit and the data forwarding unit on the MPFU work
together to send the target PIU interface. As for the protocol message and the control
message, they are processed by the processing unit of the PIU and the management
and control units of the MPFU.
4.2.3 The Introduction to the Hardware Unit
4.2.3.1 MPFU
As the control node of the product, the management and packet forwarding unit (MPFU)
of the ZXR10 ZSR V2 is responsible for data forwarding, management and maintenance.
The MPFU includes message forwarding unit, management and control unit, clock
processing unit and monitoring alarming unit, etc. It implements data forwarding and the
