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.
