Q虚拟化和集中式软件管理已经渗透到了计算和存储领域，这项技术有哪些优势？
A With Software Defined Netowork, networks are no longer closed, proprietary, and difficult to program. They are transformed into an open and programmable component of the larger cloud infrastructure. SDN gives network owners and operators more control of their infrastructure, allowing customization and optimization, and reducing the overall capital and operational costs. SDN also allows service providers to create new revenue opportunities at an accelerated pace through the creation of software-based applications –as the PC, mobile, and Web industries have been doing successfully for years.

Q什么是软件网络
ASoftware Defined Network can be configured by the administrator after the network hardware are built up. That means how the packets flow within the network is configurable and controllable in realtime. That gives network owners and operators more control of their infrastructure, allowing customization and optimization, and reducing the overall capital and operational costs.

Q大数据时代有哪些急需解决的问题？
AThere will be a shortage of talent necessary for organizations to take advantage of big data. Policies related to privacy, security, intellectual property, and even liability will need to be addressed in a big data world. The use of big data will become a key basis of competition and growth for individual firms. From the standpoint of competitiveness and the potential capture of value, all companies need to take big data seriously.

Q数据中心的转型主要是指的什么？
ALegacy datacenter runs server virtualization. Typically the network is segmented into multiple L2 domains. Then network virtualization is introduced in legacy network. An ethernet trunk is extented from Top-of-Rack switches to each virtualized server. Next, a large number of the modem clod datacenters are built using L3(routing) to the ToR switch. Then virtual services within ulti-tenant clod datacents and multi-datacent cloud network appeared.

Q内容中心网络CCN和软件定义网络SDN两者是什么关系？
AContent-Centric Networking (CCN) is designed for efficient content dissemination and supports caching contents on the path from content providers to content consumers to improve user experience and reduce costs. However, this strategy is not optimal inside a domain. Using a Software-Defined Networkinga can be a solution to improve caching in CCN.

Q软件定义网络 如何去使用OpenFlow？
ASDN requires some method for the control plane to communicate with the data plane. One such mechanism, OpenFlow, is often misunderstood to be equivalent to SDN, but other mechanisms could also fit into the concept. The Open Networking Foundation was founded to promote SDN and OpenFlow, marketing the use of the term cloud computing before it became popular.

Q能不能简单介绍一下SDN？
A SDN是透過軟體來改變網路架構與機能，讓網路可以更加自由地控制管理。深受系統的規模日漸擴大，多樣化、複雜化所困的通訊業者與企業，就可以透過這項技術來更有效率地運用網路基礎設施，甚至是減少在設備運用上的成本和維護費用。
-
QSDN网络相比传统网络有什么不同？
A In a traditional network, data flow is controlled by switches and routers. Each switch and router contains the following basic elements, data plane, control plane and management plane. SDN allows network administrators to manage network services through abstraction of lower level functionality. This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forwards traffic to the selected destination (the data plane).
-
QSDN在服务器领域有什么用？
AWhere SDN contributes is by interfacing with an overall IT infrastructure management software that can track an application through servers, storage — and elements of the network. SDN can be centralized through a single console for an overview of the network, but it is only one of numerous elements that must be linked together into an end-to-end view of an application as the app traverses servers, storage, and the network.
