The packet forwarding performance and backplane capacity of S series switch are related to the software version. For detailed specifications, contact the local Huawei office.

Backplane bandwidth of S series switches
The backplane bandwidth is the maximum traffic volume that can be exchanged between the interface processor or interface card and the data bus. The backplane bandwidth is also called switching bandwidth, which indicates the overall data switching capability of a switch, measured in Gbit/s. The higher backplane bandwidth indicates the greater data processing capability, but with higher design cost. For details about backplane bandwidth, contact your local Huawei office.

Backplane bandwidth of the HUNQ2 board
The maximum backplane-side bandwidth of the HUNQ2 board is 40 Gbit/s.

What architecture do CE12800 switches use
Description
What architecture do CE12800 switches use?
Solution
1. The CE12800 series switches use an orthogonal architecture design. This architecture greatly improves system bandwidth and scalability because it does not require cabling on the backplane.
2. The switching platform of the CE12800 series switches is based on a three-stage Clos architecture:
− On this Clos architecture, each switching unit connects to all the switching units of the next stage.
− The Clos architecture is non-blocking, rearrangeable, and scalable.
3. All modules of the CE12800 series switches are hot swappable, and key modules adopt redundant designs:
− Power modules support N+N or N+1 backup and have built-in fans.
− Fan modules support 1+1 backup, and each fan module has two counter-rotating fans.
− MPUs support 1:1 hot standby.
− CMUs support 1:1 hot standby.
− SFUs support N+M hot standby.
