NFV• (L4-L7) 네트워크 function/서비스들을가상화• Carrier의네트워크장비내의 function들을 standard high volume

server로분리시켜가상화시키는기술• Network virtualization의현실화된Telco 버전• 다양한구현방법이가능 (with SDN, without SDN)

• NFV as highly complementary to SDN• Carrier-IDC내에위치하는 standard high volume server의활용

• (기본철학 vs. 벤더구현방법은다를수있음)

Why NFV ? (Operator’s perspective)

1.Resilience (가상화) (e.g., scale-in, scale-out)

2. 새로운비즈니스의대응 (e.g., MVNO, M2M/IoT, …)

3. Network evolution (e.g., 3G-> 4G -> 5G)

Comparison of SDN and NFVCategory SDN NFV

Reason for BeingSeparation of control and data, centralization of control and programmability of network

Relocation of network functions from dedicated appliances to generic servers

Initial Target Location

Campus, data center / cloud Telco networks

Target Devices Commodity switches (and servers) Commodity servers and L4-L7appliances

Initial Applications Cloud orchestration and networking Routers, firewalls, gateways, CDN, WAN accelerators, SLA assurance

NFV Phase-1 vs. Phase-2•Guiding Principles for Current Phase “Phase 1”

• Lean towards guidance rather than detail.• Strive for consensus & be inclusive of deployment models. • Be timely & relevant.

•Guiding Principles for Phase 2• Foster interoperable implementations rather than necessarily spawning new

standards activity.• Drive towards a commonly defined and interoperable operating

environment, that can support a variety of network functions.• Strive towards normative documents that provide requirements at a reasonable

level of detail.15

NFV Phase-2 작업분야•목표

• Ensure multi-vendor interoperability.• Enable automation and simplify network operations.• Address new use cases bringing new requirements.• Identify enhancements leveraging recent advances in virtualisation and cloud

computing technologies.

• Potential work item (안)• Interfaces and information models for interoperability• Operations and evolution• Testing• Architecture & evolution• Carrier grade and miscellaneous
