S7706/S7712 System Architecture
The S7706 and S7712 have the same system architecture, which includes data, control, and management planes.
The data plane is exclusively used for transmitting service data. The data plane is physically divided into several star
data channel planes.
The control plane is exclusively used for transmitting service-control protocol packets and control information using
channels independent from other planes.
The management plane is exclusively used for managing devices. The management plane uses the CBUS.
The S7700 supports distributed forwarding architecture. All data is forwarded by local LPUs.

The data plane is exclusively used for transmitting service data. The devices on the data plane are connected
through data channels on the mesh topology.
The control plane is exclusively used for transmitting service-control protocol packets and control information
using independent out-of-band channels.
The management plane is exclusively used for managing devices. The management plane uses CBUS and
an independent power supply system.

S7700
Core devices on a network have higher security requirements. If a high volume of attack traffic is sent to a core device, the CPU usage becomes high, which leads to failure in processing control or management packets. The network fails to run properly.
The S7700 supports hardware-based CPU queues to defend against malicious traffic, DDoS attacks, and viruses, ensuring secure running of devices.
The dedicated hardware-based CPU queues of the S7700 can process control or management packets sent to the CPU in a differentiated way. The CPU preferentially processes key services.

Fans adjust their rotation rates based on the temperatures
of line cards and optical modules to minimize power
consumption.
Fans in an idle area, such as a group of slots without line
cards, work at the lowest rate: 30% of full speed and 5 W
power consumption. This reduces noise and prolongs fan
service life.
Cards in different areas are cooled
by different fan trays

Unique Left-to-Rear Airflow
• Increases air resistance by 25% as rack sides block
the air. The coefficient of performance (COP) value is
low: only 0 to 20.
• Mixes cold and hot air in the right chassis, causing a
3℃ to 5℃ temperature increase at the air intake.
• Uses low-efficiency fans that have small diameters
and run at a high speed. The fans have limited heat
dissipation capability for slots, make a lot of noise,
and provide low reliability. The system cannot work
properly when one fan module fails.
COP = Chassis Power Consumption/Heat Dissipation Power Consumption
A larger COP value indicates less energy used for dissipating heat and a higher heat dissipation efficiency.
• Optimizes cold and hot air channels in the
equipment room and reduces interference among
devices.
• Reduces air backflow and improves heat
dissipation efficiency. The COP value is higher
than 50.
• Uses high-efficiency fans that have large
diameters and run at a low speed, reduces the
number of fans by more than 30% and noise by 5

High-Density Cabling, Saving Space
Traditional switches use left-to-right ventilation channels. Restricted by poor heat dissipation, 48-port cards cannot be
installed in all slots.
The Huawei S7700's left-to-rear ventilation channel design enables the S7712 to be fully configured with high-density cards.
A 42 U rack supports 900 network cables or 2880 optical fibers, greatly saving space occupied by the switch in the
equipment room.

Customer benefits The power-scheduling data network in Zhejiang Province is an
important part of the power system infrastructure and the basis for
implementing automatic scheduling and modern management. The
network ensures secure, stable, and cost-effective operation of the
power grid. Hardware robustness has a direct influence on scheduling
services of the provincial network. This reconstruction project greatly
reduces hardware risks and ensures proper scheduling services for
the provincial network.
Customer requirements During the 10 years since the power scheduling data network in
Zhejiang Province was set up, it has expanded to include devices for
power scheduling across the province and 11 areas. The network
connects to 29 uniform scheduling power plants. During the 10 years,
the power scheduling data network has been reconstructed and
maintained, but performance of multiple devices has degraded and
they require upgrade or replacement.
Huawei solution Replace old devices in 2011 with 2 million CNY worth of new
devices, including 21 NE20-4 routers, 3 NE20E-8 routers, 11
AR3200 routers, 9 S7700 switches, 30 S5700 switches, and 56
S3700 switches.
