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

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

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

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

17 A Typical Network with SDN SDN Controller Holistic View Programmable

18 Is SDN for me? Programmable network - sounds like engineering. Perhaps very useful for data centers as they have lot of switches. Does SDN have relevance to University/Campus? I have heard that SDN is a solution looking for problem to solve. Well, SDN is definitely great for Data Centers, and, when you enable SDN in Wi-Fi infrastructure, it is even greater for the Enterprise

20 SDN Wi-Fi Enable OpenFlow SDN Controller WLAN Controller Access Point Access Point

21 SDN Wi-Fi - Enables Unified Wired-Wireless SDN Controller WLAN Controller Holistic visibility of wired and wireless networks Predictable QoS across the unified network Diagnostic across the unified network Wired Switch Access Point

22 SDN Wi-Fi - Enables Vendor Agnostic WLAN Controller SDN Controller HP, Brocade, Juniper, Extreme, NEC, BigSwitch, Dell, lot of OpenFlow Vendors Meru can offer unified wired wireless with any unlike Cisco, Aruba etc. which offer unified only if you buy all gear from them Wired Switch Access Point

23 SDN Wi-Fi - Enables Applications SDN Controller Network Intelligence Applications Business Intelligence Applications WLAN Controller Meru App Stores Opportunity to sell software/services Build your own apps or bring your partners app in the app store Wired Switch Access Point

24 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!

25 Unified Collaborator Predictable Experience for Lync

26 26 Unified Collaborator A SDN Application that provides the ability to detect quality of service (QoS) issues on the network, deliver prescriptive resolution options and prioritize traffic across multi-vendor wired and wireless networks.

27 27 Unified Collaborator SDN Controller Unified Collaborator Lync Server WLAN Controller Wired Switch Access Point

29 Unified Collaborator Advantages End to end flow control across Unified Network Single pane of glass for policy deployment Diagnosis/Troubleshooting across the unified network

31 Personal Bonjour Personal bonjour to limit visibility of bonjour services from a device to the registered user only a personal area network solution.

32 Personal Bonjour Student A Student B Student C ```` Personal bonjour limits visibility of bonjour services from a device to the registered or authorized user only Student A devices visible to Student A, Student B devices visible to Student B. Or based upon access rights as decided by the device owner

33 Personal Bonjour Meru Personal Bonjour SDN Controller NBI NBI Policy Manager Student A Student B Registered to Faculty Student A Devices visible only to Student A Student B Devices visible only to Student B MERU PROPRIETARY INFORMATION. Copyright Meru Networks, Inc. All rights reserved.

34 Personal Bonjour Advantages Access Control of Bonjour Resources No visibility to unauthorized users Single pane of glass for policy deployment No Multicast flooding OpenFlow standards based access

36 Smart Bridging Meru smart bridging intelligently optimizes traffic (congestions) on wired network bridges the flow at the AP if those flows don t need to go to the controller in tunnel mode.

37 Smart Bridging Non optimized regular Tunneled flow Optimized Smart flow

38 Smart Bridging SDN Controller Smart Bridging SDN App WLAN Controller Access Point

39 Smart Bridging Advantages U-turn (i.e. bridge) flows that don t need to go central controller in tunnel mode Optimize traffic on wired network OpenFlow standards based access

40 SDN Applications for the Unified Network Reliable Collaborator 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

41 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

42 Summary The datacenter was where the need for SDN first surfaced and was most keenly felt, but SDN is applicable across the enterprise network. SDN is the only way to achieve unified wired-wireless network experience that does not lock you with a vendor OpenFlow is the open standards way to do SDN (otherwise it becomes Vendor Defined Networks)
