Way to Implement SDN Network In Data Center

Cloud Computing Era Is Coming Cloud computing market has a bright prospect According to a report from Forrester Research, the global cloud computing market will be increased from $40.7 billion in 2011 to $241 billion in 2020. IaaS will have its peak time in 2014. The global revenue of laas in 2014 will reach $5.9 billion. The SaaS market will increase from $21.2 billion in 2011 to $92.8 billion in 2016. Amazon cloud service (AWS) has been used in 190 countries and regions. It has more than 400 thousands commercial customers including The New York Times and NASDAQ Stock Market. Google APP Engine already has more than 10 million users. Google Apps already has more than 4 million enterprise users. The cloud service provider Salesforce already has more than 100 thousands paid users. The CRM market share of Salesforce has increased from 8% in 2006 to 46% in 2011. The cloud computing service ecochain has become mature. 1

SDN Is an Irresistible Trend Traditional DC problems Slow service adaptation: Network launching speed cannot adapt to fast service development. Maturity and commercial value Service Feature/Product Chip SDN is an irresistible trend. Programmability: fast adaptation to service requirements Single service expanding: 2 months All service expanding: 6 months N months 1 year N years Time Centralized controller: unified orchestration, and easy and fast network deployment Low-efficient service deployment: complex and long-period network adjustment 1 week 10 minutes 1 week 2 weeks 20 minutes Controller 10 minutes 4 weeks 20 minutes 2

Service Chain Orchestration Flexible customization: IT Service Chain Orchestration Service A administrators can flexibly adjust value-added service (VAS) nodes through the cloud management platform. Global orchestration: Fabric provides end-to-end "Service Chain" paths. Highly efficient routing: VAS Service B nodes do not need to maintain the dynamic routing table, which reduces routing complexity. Service C Service Chain Orchestration: Build VAS nodes and customize "Service Chain" routes based on service requirements. Controller translates the "Service Chain" routes, and the network executes forwarding polices. 10
