Innovation #5 Software-Defined Networking with ENP for Future

Use software to redefine the configuration on agile switches.

When a protocol is upgraded, do we change the configuration or replace the device?

Chip supporting programmability in the forwarding plane

POF supports future protocols with ease

Architecture supporting multi-layer openness

Traditional switches must be replaced.
