2015年11月10日に開催した、「Cisco EPN Innovation Seminar ～ネットワーク変革の源泉となるオープン コミュニティ～」と題したセミナーの資料です。

1. NTT Communications
Global IP Network Operation
Yasuyuki Hamada
NTTCom Engineering Corp.
November 2015

2. What’s NTTCom Engineering Corp.?
• An NTT Communications Company since Jan 2015
• Our scope is Layer1~3 Network Operation of NTT Communications
Services

3. NTT Communications Global IP Network (GIN)

4. NTT Com's Global IP Network Japan-U.S. Capacity Exceeds 1Tbps

5. Motivation for automatic traffic control
• Many events in our network
• Hardware trouble (Simple trouble is few, it’s getting complex)
• Submarine Cable cuts
• DDoS (Recently many huge volume attack happens)
• Manual Operation is not enough
• Quick response, resources, etc.

6. Example: Trial of Enhanced DDoS Defense Orchestrator System

7. Solution?
• Intra network traffic control
• MPLS-TE (not full-automatic but external tool calculate bandwidth)
• Ingress traffic control
• BGP is one option to transfer internal network quality information to users
• Example: A user can decide which ingress point to use.
• Egress traffic control
• BGP is one option to know external network quality information from users
• Example: An IPS can decide which egress point to use.

8. Thank you!
