Market Triggers Operator’s Network Transformation: Huge Traffic Large granularity of video is the major part of the traffic in future Challenges E2E traffic flow optimization is difficult Traffic not terminating at edge

Number and type of connection will increase significantly Market Triggers Operator’s Network Transformation : Large Connection Number and type of connection will increase significantly 25 Connected devices (billion) 15 Billion 28 Billion CAGR 2015-2021 IoT equipment CAGR is 23% between 2015 and 2021, will exceed the phone and become the largest Internet equipment. Global networking equipment is expected to reach 28 billion in 2021，16 billion relates to IoT 20 Cellular IoT 0.4 1.5 27% 15 Non-cellular IoT 4.2 14.2 22% 10 PC/laptop/Tablet 1.7 1.8 1% 5 Mobile Phones 7.1 8.6 3% Fixed Phones 1.3 1.4 0% Challenges Large amount of on-demand and dynamic business requirements

(Customer self service，NaaS) Market Triggers Operator’s Network Transformation: Digital service Past （Voice、SMS） Now （OTT、Pipe） Future (Customer self service，NaaS) Challenges Operators will change from selling resources to sell services. Traditional static, closed, pre-planned network will change to dynamic, open, on-demand network.

Suggestions on CORD Platform evolution Further improve stability and efficiency of building and deployment easy update cord platform without re-deploying from scratch More stable process for PXE booted computer nodes Multiple options for computer node installation: MaaS booted vs. others ways for computer node installation Cooperation with other Open Source Community and Standard Organization ONAP 、OPNFV、OCP、OVS…. MEF、BBF、ONF… Work together with all partner to build the ecosystem

Suggestions on CORD Platform evolution The mechanism is different between operator and the Open Source Community Development: per-plan the development plan、slow speed of development Operation: service change at any time 、quickly deployment and adjustment The lab testing vs deployment in real network Distribute architecture of head nodes for practical deployment: De-couple among the cord platform infrastructure services XOS cluster Openstack cluster ONOS cluster
