  2. 2. 목차 2. NFV & SDN 1. Why NFV ? 3. Where are we ? 4. Where we go ?
  3. 3. Why NFV ?
  4. 4. Gartner Said X86서버의50%가가상화되어짐 VM 간의통신폭증 18개월마다서버당가상머신수2배씩증가 2014년에네트워크트레픽의80%가서버간에서발생
  5. 5. •네트워크변경은어렵고, 위험하고, 느림 •트래픽의증가에대한대처가느림 •새로운서비스를추가하기위해서는비싼새로운기술추가 •막대한돈소요 계층적구조 일반적인네트워크구조 단일구조 폐쇄적 유연하지않음 Problem of Present Network Architecture 상하 트래픽중심설계
  6. 6. Heavy Increases of Network Traffic Visual Networking Index Forecast, 2012-2017 Busy vsAverage Internet Traffic Growth per Month of IP Traffic in 2017 네트워크트래픽증가 네트워크장비비용증가
  7. 7. Alternative ? 1. H/W 와S/W 분리 2. H/W 는x86 3. Software networking 4. Virtual Networking 네트워크장비비용을줄이자!!
  8. 8. Decoupling Hardware From Software Custom Network OS Custom ASIC HW Standard Server Network OS Reduce $ Reduce $$
  9. 9. Software Virtual Network 유연성과확장성증대 소유/운영비용절감 필요에따른손쉬운Scale up / Down 프로그래밍으로네트워크추가/삭제/변경/업그레이드 Scale Up & Down Users Speed X86 H/W발전에따른성능강화 손쉬운운영과장애처리 VM 으로동작( 자원이동용이) 자동화(부하조절)
  10. 10. NFV & SDN
  11. 11. SDN ? “ Software Defined Networking(SDN) is an emerging network architecture where network control is decoupled from forwarding and is directly programmable.. “ SDN의정의 Control 과Data Plane 분리 API 지원 x86 네트웍기능가상화 프로그램으로제어 SDN 의특징
  12. 12. •Configuration Interfaces •CLI, GUI, REST API •Policies •RoutingFW/ NAT •PolicyQoS •VPN TerminationNetwork •BridgingInterface Drivers Separating Control From Data Planes
  13. 13. NFV ? “Network design must be more agile and able to respond on-demand to the dynamic needs of the traffic and services running over it, Key enabling technologies for this include SDN (Software Defined Networking) and NFV (Network Functions Virtualization)“ NFV의정의 European Telecommunications Standards Institute
  14. 14. NFV & SDN (Network Functions Virtualization) NFV SDN (Software Defined Network) 네트워크장비에서H/W, S/W 분리 범용서버의가상화기반 네트워크기능가상화제공 Data 와Control Plane 프로그램으로제어 네트워크장비에서H/W, S/W 분리 Protocol
  15. 15. Difference between SDNandNFV Software Custom HardwarePurpose-built dedicateddevice 정형화된x86 서버의가상화환경내에다양하며융합적인네트워크장비를사용가능하게하는기술. (firewall, switching, routing, ADC, BRAS, EPC, etc. ) 능동, 신속성증대그리고투자비감소 NFV SDN Software Software Hypervisor x86 HardwareIndustry-standardserver 기존의Control-plane과Data-plane을분리하여지능적이며프로그래밍가능한Controller에서Control-plane을관장하는기술. SDN Controller Control plane 프로그래밍에따른혁신및자동화

NFV 기술은이동통신기지국기능을소프트웨어로구성해일반서버도기지국처럼활용할수있게해준다. 지난해내놓은인맥관리솔루션`유플러스내비서`나올IP 대화서비스`우와(Uwa)` 등이이러한NFV 기능위에서구현
