3 UK Install base - FE Over 2500 Schools in the UK since 2007 have chosen Meru

4 UK Install base - HE

5 Mobile Growth Continues! 1.62 billion mobile devices BYOD trend started 59% organization s support BYOD By 2020, IDC predicts that third-platform technologies (mobile, cloud, social and Big Data) will comprise 80 percent of all IT spending, compared with 20 percent in 2011

6 Wireless is no longer a nice to have Wired Switch Applications Servers Wi-Fi Access Point The End user experience depends not only on how good the Wi-Fi is but how well you have control over the wired network

7 History of SDN Gartner Publishes ONE Magic Quadrant for the Wired and Wireless LAN Access Infrastructure Connectivity at the edge of an enterprise network is more than just a wired or wireless LAN infrastructure. Enterprises must chose infrastructure vendors that can integrate wired and wireless networking products Source: Gartner Magic Quadrant for the Wired and Wireless LAN Access Infrastructure Published: 13 June 2012

OpenFlow Concept Originated at Stanford work by Casado and McKeown The term SDN coined by MIT Technology Review when Casado and McKeown s work at Stanford was featured in the TR10 in March/April 2009 HP makes a major push in SDN Champions OpenFlow/SDN Over 15 million OpenFlow enabled ports 2013: NEC as 1 st OpenFlow Certified Wired company

12 What is SDN?

13 A Typical Network

14 A Typical Network Requires Effort Manual CLI/Scripts Box-by-box Human middleware

15 A Typical Network Element Memory CPU Mgmt Plane Telnet, SSH, SNMP, NTP, SYSLOG, HTTP, FTP/TFTP Flash Switching ASIC Control Plane Network topology, ACLs, Forwarding & Routing, QoS, Link Management Every element has its own intelligence & configuration Every vendor defines unique ways to configure the box Transceivers Forwarding Plane Link, Switching, Forwarding, Routing network element such as a switch

16 And in SDN, Memory CPU Flash Switching ASIC Mgmt Plane Telnet, SSH, SNMP, NTP, SYSLOG, HTTP, FTP/TFTP API SDN Controller Devices EXPOSE API to program SDN its forwarding Controller plane A software, SDN Controller makes all forwarding decisions. Transceivers Forwarding Plane Link, Switching, Forwarding, Routing network element such as a switch

17 A Typical Network with SDN SDN Controller Holistic View Programmable

18 SDN Wi-Fi Enable OpenFlow support in WLAN Controller or your autonomous/controller-less APs SDN Controller WLAN Controller Access Point Access Point

19 SDN enables Unified Wired-Wireless SDN Controller WLAN Controller Wired Switch Access Point

20 With SDN Wi-Fi, you achieve Holistic visibility of wired and wireless networks No Vendor Lock-in (mix and match) Predictable Quality of Service across the unified network Insight/Analytics across the unified network Diagnostic/Troubleshooting across the unified network Unified Wired Wireless is the PROBLEM that SDN for Enterprise can solve, and can solve very well!

21 Meru a wireless network focused on the end user Current issues Roaming Solutions Virtualisation Sticky clients Network in control Coverage not Density Complex management Fair usage Complexity in connecting Future proofing Apple Bonjour End to end application delivery Channel Layering Single channel Airtime fairness Smart Connect [eduroam] ac Service Control SDN

22 WLAN Architectures The evolution of the distributed mobile enterprise Fat AP Hot Spot Microcell Centralized Virtualized Single Channel Application specific Wireless Wi-Fi Usage Casual Convenience Business- Critical Mission- Critical Prime Transport Changes in App Delivery Fat Client Thin Client SaaS Mobile Cloud

23 The Latest standard ac and why fully utilising it s capabilities is important! Higher throughput for legacy and new devices Latest standard Better ROI Improved end-user experience Greater density of devices

24 Wider Channel Widths for Bigger Payloads MHz 5330 MHz 5490 MHz DFS Weath er radar Not allowed in North America 5730 MHz IEEE channel # 20 MHz 40 MHz 80 MHz 160 MHz The DFS Channels (Dynamic Frequency Selection) FCC Rule # (h)(2) requires that products operating in the UNII-2 and UNII-2 extended bands ( GHz and GHz) must support Dynamic Frequency Selection (DFS), to detect and automatically adjusts channels to protect WLAN communications from interfering with military or weather radar systems. All WLAN products that ship in Canada and the US on or after July 20, 2007 must meet the DFS for FCC requirements.

25 80MHz or 40MHz? Bandwidth # of spatial Streams 20 MHz (Mbps) 11ac (11n) 40 MHz (Mbps) 11ac (11n) 80 MHz (Mbps) 11ac 160 MHz (Mbps) 11ac /(65) 200/(144) /(144) 400/(300) /(216) 600/(450) /(300) 800/(600) *Phase 1 in Green

26 Rate and Range Power and space challenges are still the same Don t expect more than 3 data streams soon (-) Higher rates available at ranges closer to the AP (-) Higher throughput efficiency mean less time (power) spent for transmit (+) Users will still observe greater net throughput (+) Thank You

27 Some SDN applications

28 SDN existing examples: Lync

29 The Student Experience Connectivity Where Needed Campus Campus Library, Classroom, LRC Library LRC Classroom Classroom Classroom Halls Home like experience Dorms Dorms Dorms Remote Home, Distance Learning Clients

30 The Student Experience Home network Internet Printers Tablets and Smart Phones Within the home network all devices can connect NAS box or home server Apple TVs and Smart TVs PCs and Laptops

31 The Student Experience SDN Enhanced Individual Student s network University IT infrastructure Internet Personal Area Network Tablets and Smart Phones SDN Controller PCs and Laptops Printers Apple TVs and Smart TVs NAS box or home server

32 SDN Applications for the Unified Network Reliable Collaboration Automated end to end QoS Real time/improve IT Agility Reduce configuration complexity & cost of deploying Easy Diagnosis and problem isolation Energy Manager Save on energy costs by turning off the PoE ports for the Wi-Fi Access points that are not in use Wi-Fi Rate Adapter Dynamically adjust wireless rate with the WAN pipe usage

33 More SDN Applications Location/Analytics Actionable information based on wired or wireless location of asset/person Compare User/Customer Behavior and harvest for customer s business growth BYOD Security Automated across the unified network Real time proactive threat detection Lower costs by reducing need for dedicated security devices Traffic Control Accelerate the traffic for optimal application experience

34 Key Takeaways SDN a Network without boundaries Network in control ac No sticky clients Linear scalability with channel layering What is preventing you from deploying an all-wireless campus?
