加入BBWF2014

网络函数虚拟化并软件定义网络将在今年BBWF2014宽带世界论坛引起极大兴趣,与服务提供商和大型企业交谈时,显然我们已经进入网络产业的另一大过渡阶段。

VF和SDN对网络意味着什么,我与许多有才能个人交谈过。其中一些视觉分布宽广长广,有些比较偏重快速交付或优化单服务。很明显NFV已被部署在许多不同的服务应用中,而SDN开发焦点跟踪速度明显慢化。即使是在实例中也是如此。虚拟网络函数内建系统等典型网络函数虚拟化,如虚拟化路由反射器x86服务器上反射器而不是运行线路反射程序

These NFV implementations have had a greater near term impact because they are quicker to deploy and have an arguably more immediate business impact.  If you think about SDN, it's an efficient way of managing large mixed networks and orchestrating NFV.  SDN is a much different task once you add the clause about mixed networks and once you consider the operational impacts of network wide orchestration capabilities.  Mixed networks in this context could mean deploying virtualization across multiple market segments like virtualized mobility, virtualized video, and virtualized network assets.  It could also apply to multi-layer services and multi-vendor deployments.  Anytime we discuss multi-layer convergence I see people start to squirm in their seats.  Making service delivery work across multivendor environments is even more complicated, but within this network evolution Multi-layer and multi-vendor are absolutely required.帮助解决混合网络管理调试使SDN的承诺如此强大

建立虚拟化必备文件列表 供我们接近BBWF14时参考

虚拟化需求

1. 端用户服务自服务门户创建修改
2. 多视频多路提供管理
3. 完全自动化编译服务减少操作费用
4. 服务基础设施VNF
5. 多重VNF服务链
6. 弹性用量/部署选项包括:
   1. 个体VNFs
   2. VNFs加SDN编程
   3. 完全集成SDN编程、设备部署服务
   4. As-As-Service提供模型

That's a quick list and I would guess that other than As-a-Service options, the rest of this is somewhat expected, sometimes overlooked, yet well understood.  As-a-Service options are well understood too.  I have seen more Service Provider interest in As-a-Service options in the past 12 months.  Much of this is due to either the desire to trial a new service with a lower first cost, or increased service velocity in competitive environments.  As-a-Service options are also attractive when trying to compete outside your typical service geography, or in other words to meet high priority customer requirements for a global service in regions that you don't normally have network assets deployed.

BBWF2014应是一个大事件 。我期待基调、辩论和新手展示博览会 。在如此短的时段内,这么多事需要消化, 重要的是先知道想看什么再走
