2 The Ways of Communication Evolve

3 Operator s challenges

4 Challenge 1 Revenue Growth Slow Down Expense rate device platform content Voice dominant Profit gap Data dominant Revenue growth time Revenue & investment decouples open network platform OTT Mobile Apps in Ecosystem Inefficient service delivery: the complex multi-network environments jeopardize the service s delivery in time and quality legacy income dropped: voice/text message are replaced by the novel mobile Apps (FaceTime, Line, Skype etc) Lost the initiative in emerging business: the traditional business and service model were broken. OTT services and smart device apps grab the money from users and investors

5 Challenge 2 CAPEX Increase Emerging technologies (3G/4G LTE, WiFi, xpon, PTN, OTN) drive huge investments over the network infrastructure upgrading Severe competition pushes increasing the coverage and bandwidth for wireless & optical to sustain the market shares Mobile data big bang: data traffic had exploded about 13 times compared with end of 2009

6 Challenge 3 OPEX Increase Complicated & Inconsistent Networks: manage a huge amount of various boxes from different NE vendors, heterogeneous EMSs and control planes Emerging services and Apps create a huge burden over network, increase the work of maintenance Lack of innovative technology for operation & management over the complex network and the control mechanism within the network devices

7 Challenge 4 Data Traffic Control SNS (5.2%) Etc. (13.5%) App. Store (13.6%) Multime dia (34.7%) Uniqu e (70%) Duplic ated (30%) Web (33%) Data traffic unbalance & duplication: The distribution of data traffic is skewed severely, and about 30% of data traffic is duplicated Unfair bandwidth occupation: traffic dominated by few power users causes unfairness for the rest of majority users; wired: 5% users dominate 50%, wireless: 1% users dominate 45% QoS Degrading: P2P traffic makes the multiple IP flow and causes unfairness issue Mobile Apps stay continuous on-line: overload the signaling control path

8 Challenges & Solutions observation Revenue Growth Slow Down Inefficient service delivery legacy income dropped Lost the initiative in emerging business CAPEX Increase Emerging technologies investment Severe competition OPEX Increase Complicated & Inconsistent networks Lack of innovative technology for operation management OTT mobile Apps cause network unstable response Manage exploding, dynamic data traffic, low-cost, simple & high capacity solution for Infrastructure, Programmable Network (by SDN) Big Data Analysis (new business) Smart pipe to provide quick new service in time Network Function Virtualization (NFv) technology (simplify variety of HW models) Distributed CDN & Smart Push (to balance the data traffic) Data Traffic Control Data Traffic Unbalance & Duplication Data unfair BW occupation & QoS degrading Mobile Apps stay constantly on-line

9 Is there any solution?

10 Definition what SDN ONF (Open Network Foundation) A new approach to networking and its key attributes include: Separation of data and control planes A uniform interface called OpenFlow between control and data planes A logical centralized control plan slicing and virtualization of the underlying network IETF (Internet Engineering Task Force) An approach to network that enables applications to converse with and manipulate the control software of network devices and resource

11 we SDN app app app app app SDN network OS abstraction layer hardware SDN SDN network OS abstraction layer hardware SDN SDN network OS abstraction layer hardware network OS network OS abstraction layer hardware abstraction layer hardware SDNs are subset of programmable networks, manage the entire network resource, enable networking application to request and operate services provided by the network, allow the network controller to provide network state to the applications

12 SDN SDN Provides two important interfaces, Northbound API, and Southbound API Northbound API: provide network programmability by applications, abstract networking technology details from the applications, and enable automation, on-demanding capabilities Southbound Interface: abstract networking protocols details from NetOS/Controller and provide vendors-independent programmability of network elements

13 SDN Resource Management Network virtualization Policy enforcement QoS Automation API for Apps Openness & standardization

18 our SDN solution

19 development our SDN 2013/7/26 Distributed domain Controller Distributed domain Controller

20 SDN Controller PTN Control & our SDN

21 our SDN Hybrid migration is the strategy to deploy SDNs The hybrid architecture enables a simples phase approach to the network transformation to SDN Traditional distributed model: tight coupling control and data plane Hybrid control model: the network element supports the separated control to SDN controller in additional to old control plane. Centralized control model: only support OpenFlow in the network element

22 network our SDN Provide a bottom-up view of the entire network Exploit visualization techniques showing integral star view, cloud view and ground view Simplify network operations with a powerful, intuitive GUI fast and easy point-and-click provision of e2e services

23 our SDN Star view: show the available network POP (Point of Presence) to customers Cloud view: show the logical link and devices within the source and destination points Ground view: show network devices physical location & connections within the source and destination points
