5 What is SDN? Traditional Networking Devices Control Forwarding Control Forwarding L1-L3 Device L1-L3 Device SDN Decouples control & data planes (CP & DP) Centralizes CP Provides network programmability via APIs App 1 App n SDN OpenFlow (OF) OF is just one option for decoupling CP & DP APIs Centralized SDN Controller DP under SDN control may span L1-3 e.g., optical, Ethernet, MPLS, IP routing e.g., OpenFlow Forwarding L1-L3 Device Forwarding L1-L3 Device SDN & Cloud are complementary Cloud may cost-reduce controller & apps SDN simplifies & helps automate cloud orchestration Software Defined Networking IST IEEE ComSoc Ericsson Telecomunicações, Lda Page 5
