QSDN的应用领域有？
ACloud computing applications could be a big beneficiary of software-defined networking and OpenFlow because these technologies make provisioning in a multi-vendor virtual environment much simpler. A controller-based load balancing application could automate the movement of workloads among virtual machines by using the controller's library of data about the capacity of individual network devices. Much like virtualized network services appliances that are deployed on virtual machines, controller-based applications are more scalable, flexible, efficient and manageable than more conventional models that rely on physical devices to support functions. From a service provider perspective, OpenFlow could also promote better service to the end user by allowing for optimization with less oversubscription.

Q大量接入带来哪些技术挑战？
AI assume 大量接入 to be high speed input interface, like 10G-base ethernet. If not, please clarify it. Thanks! To support 10G ethernet or even higher, to implement the physical layer is a big challenge. The MAC, PHY and switch for 10G-base support need high-performance CPU and more memory to process the packets efficently.

Q飞思卡尔这些方案的可扩展性如何？
A Freescale QorIQ products have very good roadmap. We have new high-end T series with dual-thread support and 28nm process for data center and SDN market. For low-end, we have LS series with embedded ARM core. The LS series have low power number, low cost and plenty of SW supports. It is easy to migrate to high end or cost down to low end products on selecting hardware platform. Besides, with our SDK support, the software migration can be easy for engineer as well.

QNFV和SDN的区别是什么？
ANFV stands for network function virtualizations that virtualizes entire classes of function into building blocks that may be connected, or chained, together to create services. SDN is Software Defined Network which makes network backbone configurable and controllable in realtime.

Q主持人，你好，我还有如下疑问： 1.你刚才提到的FSL的i.MX产品在进行RSA 2k bit的数字签名认证时处理时间much less，请问这个时间可以再明确一些吗？ 2.在车载领域，FSL预计何时能够有集成above 2k bit的RSA硬件加密模块的MCU产品？ 3.在车载领域，MCU的哪些特性对RSA算法的软件实现性能有主要影响？ 谢谢！
AThis depends on which i.MX product you are using. The product specification should have the performance number. To answer your MCU specific question, it is best to contact the freescale sales or distributor and properly they can recommend a product that meet your require performance level.
