L1-L3 Device
› SDN
– Decouples control & data planes (CP &
DP)
– Centralizes CP
– Provides network programmability via
APIs
› SDN ≠ OpenFlow (OF)

› DP under SDN control may span L1-3
Centralized SDN Controller

– e.g., optical, Ethernet, MPLS, IP routing
› SDN & Cloud are complementary

3) Network inventory for Transport,
Packet & DC
- SDN controller can influence
distributed CP in packet network.
- I2RS, BGP-LS
- More pre-determined paths and
