Network Functions Virtualisation – Introductory White Paper
Issue 1
Network
Functions Virtualisation
ETSI GS NFV 001 V1.1.1
(2013-10)
An Introduction, Benefits, Enablers, Challenges & Call for Action
OBJECTIVES
This is a non-proprietary white paper authored by network operators.
The key objective for this white paper is to outline the benefits, enablers and challenges for Network
Functions Virtualisation (as distinct from Cloud/SDN) and the rationale for encouraging an
international collaboration to accelerate development and deployment of interoperable solutions
based on high volume industry standard servers.

unavailability can be attributed to server crashes or lack of networking reachability and

it indicates that a server can stay up for an average of nearly two years (0.5 unplanned restart rate).
This is consistent with our intuition that most restarts are due to planned events such as software

! 費用対効果について
"  VNF/NFVI/COTS vs 専用機
– 「品質と価格」のバランスが取れないケースも
– Zero-Loss Throughputの壁
– ベアメタル捨てられない
"  レイヤの分離による保守コスト増加
– ロックオンの入り口

– 「VXxxxx EXXxのverxxxでないと動作保証できません」
– 「その程度のメモリではとてもとても」
– 「全て弊社の製品であれば動くんですけど」
"  「おれおれデータ」が横行(チャンピオンデータ)
– 「構成は?」「さあ?」というケースは、いまでもあります
