1) Smart mobile devices are proliferating rapidly, with twice as many smart devices shipping as laptops in 2011, driving major changes in IT infrastructure needs. 2) The rise of BYOD and mobile workers is challenging IT departments with flat budgets to accommodate diverse devices and applications. 3) A distributed wireless architecture that is scalable, reliable, and cost-effective is proposed to address these issues, with centralized control and distributed forwarding to maintain functionality even if a controller fails.

Editor's Notes
- #4 Users are mobile and devices are no longer just e-mail or TextingRobust, real-time communication over wirelessAdoption is huge but IT budgets are flat3-4x increase in number of devicesAs IT staff are typically not RF experts Wireless inherently more complicated than wiredPeople want to BYODHow can you accommodate?CIOs want to leverage virtual desktop environments on commodity devicesIf the device is doing less, then network must do more for security and QoS
- #6 In 1999 there were no handhelds with Wi-Fi and very few laptops even used it as a standard. So not only was the presence low but the usage was very light.By 2003, .11g came along and some early handsets started to use it. It also started to become more standard in laptops and began to appear in some machine to machine communications.In 2007, the iPhone appeared and demonstrated that full-motion video, websites, real-time communication all translated to real, useful, business and life changing applications. Things could happen in real-time and these devices were powerful and inexpensive (by business standards). CIOs started to want them.Today, these devices are so robust they are replacing specialized, more expensive laptop technologies and even paper applications in some sectors (NFL playbooks are soon to be a thing of the past).
- #7 Cooperative control is a re-imagining of the control model for wireless networks that is only possible today thanks to Moore’s Law. What we can do with APs operating together and cooperating is was not possible 8 years ago unless you wanted to make an AP that cost $5000+ a piece. Now they’re below $500 per AP.This is similar to a grid computing paradigm where many computers are working together to solve bits of a common problem…in this case the problem is applying rules, policy, etc to massive amounts of data in real-time. Its also analogous to a global OSPF network where each router share state with the neighbors and it creates a resilient, failure-proof network.This greatly simplifies the network deployment and ultimately allows you to scale and start enabling cloud services on your network. Out in the future when 802.11ac comes along with 1Gbps wireless connectivity, then scalability and bottlenecks will be very very clear. That’s not of a few years yet but the decision needs to be made right now.
- #15 Scalabiilty is much higher today and it can scale infinitely. No controller bottleneck.
