Today’s Presentation 1 Challenges ahead 2 Technology Innovations 3 DCI solution 4 Wrap-up

Web-scale Networking Challenge Ahead On-demand Content Consumption, Mobile and IoT are Changing Cloud Networking Requirements

1X 5X 50X Unpredicted Demand Growth: Target Traffic 5X Worst Case Estimate 100 million consumers will shop in augmented reality by 2020, according to Gartner.(Oct 16, 2016) 50X Actual Traffic Source: https://cloudplatform.googleblog.com/2016/09/bringing-Pokemon-GO-to-life-on-Google-Cloud.html

Distributed Cloud Architecture Challenge: Populate the Edge Cloud quickly and dynamically Suggests more agility in the Transport System to get content to the edge Real-time Low Latency Local Relevance Global Relevance Data Centers “everywhere” – all needing Scalable, Dynamic & Agile Inter DC connectivity

Disaggregated Data Centre CBD Regional Metro Multiple DCs function as shared resource pool ICP/ DCO business models increasingly rely on Scalable, Dynamic & Agile Inter DC connectivity

but…. Traditional Networks are Static 100+ MB Worst case Demands Network overbuilt to handle worst case peak traffic demands 4MB Worst case Conditions 350kB Network overbuilt for EOL, Fiber inaccuracy, MTTR etc… 20kB Text message Photo via Instant Message 1 minute of video 1 minute of virtual reality video

but…. Traditional Networks are Static…. ~3 days ~2 days ~9 days ~5 days Order Submit Sales Engineering Details Design Circuit ID Assignment Check Order Managemnt Order submit starts parallel fulfillment process QA: check network Check service design Provision Internal service request schedule PM Update inventory Test and accept Billing Activated Complete On-net (fiber is in place) and slow in service activation Worst case Demands Network overbuilt to handle worst case peak traffic demands Worst case SLAs Network overbuilt to handle MTTR, BoD, etc… Continuing with network overbuilds and resource underutilization NOT sustainable in today’s environment
