4 3 Why do SDN/NFV transform netowrk? Differentiate services (Innovation) Increase user experience Provide unique service which is not in the market Time-to-Market(Velocity) Not to depend on vendors feature roadmap Develop necessary feature when you need Cost-efficiency Reduce OPEX by automated workflows Reduce CAPEX by COTS hardware 3

5 Where is target of NFV, SDN in telcom network? SDN Software switch is the most important components for any service. Network Function (NFV) is suitable for SDN. VM VM NFV NFV VM VM Hypervisor Virtual Switch Hypervisor Virtual Switch Hypervisor Virtual Switch TOR Gateway CPE Data Center Wide-area Network Access Network Intranet We are developping high-performance SDN Software switch Lagopus. We are also developping NFV accelerator as VNIC which Lagopus supports. 4
