Network Functions Virtualisation – Introductory White Paper Issue 1
Network Functions Virtualisation
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.

week—approximately 1% of the population—the average annualized restart rate drops to 2.53. In
another internal study conducted recently (data courtesy of Andrew Morgan, Google Inc, 2013)
planned server unavailability events were factored out from the total machine unavailability. The
remaining 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
and hardware upgrades.
Figure 7.3: Distribution of machine downtime, observed at Google over 6 months. The average annu-
alized restart rate across all machines is 4.2, corresponding to a mean time between restarts of just less
7.3. MACHINE-LEVEL FAILURES

! 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
" 頑張って検証、頑張ってチューニング
– 仮想IO系技術でがんばる（DPDK, SR-IOV・・・）

NFV Reality(2)
! MANO
" インタフェイスが複雑
– ETSI仕様通りに実装するの？
– スキーマ、モデル
" 発生する大量のイベントをどう扱うか
– 10万ノード、100万ノード
– Auto Scaling, Self Healing
– Deep Learning, コグニティブ？
! VNF / Controller開発保守
" ベンダーさん「年額ライセンスを対象VM数だけ買ってね」
" 作る？買う？保守はどうする？
" OSSのパワーをどううまく利用する？
" 既存Toolchainの活用とアレンジ

NFV Reality(３)
! 標準化と相互接続性
" ETSI NFV ISG, IETF, ITU-T, TMforum…
" 標準準拠が相互接続を担保する状況まで、遠い
" 現状は「検証命」
! よくわからない前提が横行
" 去年あたり、よくあった会話
– 「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
" スタンダード、Tipsがない。相互接続データが足りない
– Interop、次世代NSPコンソーシアム
