Cisco Enterprise NFVIS 包含了几个软件和多个硬件。
1.Cisco Enterprise Service Automation (ESA)
2.VNFs
Cisco Integrated Services Virtual Router (ISRv),
Cisco firewall (ASAv),
Cisco WAN acceleration (vWAAS),
Cisco Firepower NGFW Virtual (NGFWv),
Cisco wireless LAN controller (vWLC)
3.Unified Computing System (UCS) and Enterprise Network Compute System (ENCS) hardware platforms
4.Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM)
5.Cisco Prime Infrastructure

软件下载，一个是ISRv的，一个是支持UCS的Hypervisor.

软件下载截图

一个是ISRv的软件下载：

• ISRv Software
  一个是支持UCS的Hypervisor.
• NFV Infrastructure Software
  应该把 ASAv, NGFWv，WLCv 都整合在一起，包括以后第三方的一些虚机软件。

总之，感觉以后网络设备和计算主机设备全统一了，网络接口都是以太网接口，1G，10G，40G，100G的，交换机，路由器，防火墙上有一些处理网络协议的专用芯片，例如硬件处理VXLAN的帧格式和处理ACL的芯片，其他都一样了。上层都是支持x86的虚拟化的软件。让后是自动化，统一编排和部署。的确简单了。但是，业务层面的变更却变得日益复杂了，大量人工消耗在跟踪业务需求的变化。这也是虚拟化带来的业务快速变化的新挑战。

一般来说，Release Notes 一定要好好阅读，有坑儿的介绍。

不错，又学习了新知识。看看中国客户什么时候全面实现 NFV。尤其是远程分支机构里面的网络和计算部署硬件和网络连线应该变得非常简单。但是，软件和业务流程的变化将会变得越加复杂。
