Service Provider SDN Some key applications
1
1 Dynamic Service Chaining CAPEX savings in VAS dimensioning, faster service introduction
2 2
SDN for Cloud OPEX savings from faster service enablement, REVENUE from faster time to market
3 3 Virtual Enterprise Gateway Virtual Home Gateway OPEX savings from simpler devices, REVENUE opportunities moving up the value chain

IP & Optical transport What’s new with SDN connectivity
Traditional IP/MPLS
Traditional Transport
Dynamic
Guaranteed resource

More dynamic resource reservation with SDN
Complete control of BW and performance for IP paths
Dynamic (application)
SDN (SDN + SEGMENT ROUTING)
Stricter control on used resources and load balancing
Dynamic
Directly exposed to application
SDN (VPN OVERLAY) vNAT, vFW
Configuration, automatic VPN setup
