2 Strategic Approach to Vision Deliver breakthrough experience Offer compelling applications in growth areas Upgrade to session based environment Virtualized Services Next-generation cloud network infrastructure Avaya VENA 2011 Avaya Inc. All rights reserved. 2

3 Is your network ready..? The Private Cloud Better time-to-service with less complexity Virtual Enterprise Network Architecture Virtualized Data Center Backbone Operational efficiencies and flexibility Campus Network Virtualization Best effort moving to real-time ready 2011 Avaya Inc. All rights reserved. 3

4 Avaya VENA for the Data Center Virtual Services Fabric deployed within and between Data Centers creating the Private Cloud infrastructure Data Center Consolidation DC1 DC2 VSN Workload Mobility Bandwidth of 10 Gigabit and Beyond Simple & Efficient Provisioning Servers are dual-homed for active/active connectivity s provide secure connectivity with one touch provisioning 2011 Avaya Inc. All rights reserved. 4

5 Why extend Avaya VENA to the Campus..? Simplify Configuration & Management Efficient service activation free of error & delay Optimized Traffic Separation Ensure regulatory compliance & multi-tenant partitioning Delivering Network-as-a-Service Creating the only optimized end-to-end Cloud architecture 2011 Avaya Inc.

8 Existing Network Architecture Physical Topology Compute Access Data Center Core Campus Core Distribution Layer Access Layer Today s networks are not optimized for virtualized content delivery and next generation business collaboration VENA streamlines service delivery, provides traffic separation, and virtualizes network delivery 2011 Avaya Inc. All rights reserved. 8

9 Transition to the Virtual Services Fabric The physical infrastructure becomes irrelevant On-demand connectivity services where needed Network tiers not important as Fabric becomes the interconnect Virtual Services Fabric extended from the Data Center to the Campus Switch Clustering to the Edge for active/active connectivity 2011 Avaya Inc. All rights reserved. 9

10 Creation of s Network-as-a-Service Network Access Control authenticates Users & assigns to appropriate /VSN Management Identity Engines Ignition Server provides NAC Policy Enforcement Network Management and Network Services traffic isolated and secure from general network traffic 2011 Avaya Inc.

11 Virtualization Services Layer 2 Mapping of a Layer 2 into a delivering seamless Layer 2 extensions Layer 3 Mapping of a Layer 3 VRF into a delivering seamless Layer 3 extensions Inter-VSN Routing Enhancing IEEE 802.1aq by offering a policy-based Layer 3 internetworking capability of multiple s IP Shortcuts Native IP routing across the Virtual Services Fabric without the need for s or any additional IGP 2011 Avaya Inc. All rights reserved. 11

12 Example: Wireless Guest Services Layer 2 Mapping of a Layer 2 into a delivering seamless Layer 2 extensions Business Requirement Provide Wireless Guest Access in specified locations throughout the Campus Ability to quickly add / remove Guest Access from certain locations within the Campus Guest traffic must be isolated from internal network traffic Authentication of guest users required for compliance and security tracking 2011 Avaya Inc. All rights reserved. 12

13 Example: Wireless Guest Services The complexities we have to deal with today... Identity Engines Ignition Server Guest Manager Data Center Core Campus Core Distribution Layer Access Layer Internet Self-service Kiosk for Guest Access Many touch points for configuration / management / troubleshooting Broadcast domain seen at all points through the network Isolation of traffic 2011 Avaya Inc. All rights reserved. 13

14 Example: Wireless Guest Services Scalable, stable Guest WLAN networking Identity Engines Ignition Server Guest Manager Wireless LAN Guest Internet WLAN Guest Self-service Kiosk for Guest Access VRF separates guest traffic from all internal traffic with dedicated Internet connection Wireless LAN Guest Wireless Guest mapped into VSN maintains traffic separation Layer 2 extension across the Virtual Services Fabric /VSN provisioning at Fabric edge only 2011 Avaya Inc. All rights reserved. 14

15 Example: Multi-tenant Networks Layer 3 Mapping of a Layer 3 VRF into a delivering seamless Layer 3 extensions Business Requirement Provide campus infrastructure to support multiple different customers (airport, education, government, etc.) Maintain traffic separation between customers for data integrity and security Offer dynamic network to accommodate geographic location changes for network connectivity Share common resources where applicable (i.e. unified communications) 2011 Avaya Inc. All rights reserved. 15

16 Example: Multi-tenant Networks The complexities we have to deal with today... Compute Access Data Center Core Campus Core Distribution Layer Blue Departmental Access Layer Application with IGP configured for routing L3 Core with VRF & MBGP Green Departmental User s with IGP configured for routing VRF Configuration VRF to VSN Mapping Will be simplified by... VRFs traffic separation which is maintained through VSN Layer 3 VRF extension across the Virtual Services Fabric Use of shared services becomes simple and efficient 2011 Avaya Inc. All rights reserved. 16

17 Example: Multi-tenant Networks VRFs create traffic separation which is maintained through VSN Layer 3 VRF extension across the Virtual Services Fabric Use of shared services becomes simple and efficient Blue Departmental Virtual Services Network Green Departmental VRF Configuration VRF to VSN Mapping 2011 Avaya Inc. All rights reserved. 17

18 Example: Workgroup Networks Inter-VSN Routing Enhancing 802.1aq by offering a policy-based Layer 3 internetworking capability of multiple s Business Requirement Provide network access for a common set of users (department, agency, contractors, etc.) Maintain traffic separation for this set of users from the rest of the network Offer connectivity between this common set of users and applications that reside within the Data Center No desire to extend s across Campus to achieve this 2011 Avaya Inc. All rights reserved. 18

19 Example: Workgroup Networks Workgroup able to communicate with each other and applications Traffic separation is maintained through VSNs Security without the need for complex ACLs or separate hardware Workgroup Location A Workgroup A Workgroup Application Workgroup Application Workgroup Location B Workgroup B Inter-VSN Routing allows communications between different Virtual Services Networks without the IGP complexities 2011 Avaya Inc. All rights reserved. 19

20 Example: Business Collaboration IP Shortcuts Native IP routing across the Virtual Service Fabric without the need for s or any additional IGP Business Requirement Deploy new business collaboration services within the enterprise to provide high definition desktop video capabilities Simplify and optimize deployment across network infrastructure Ensure proper quality of service to provide acceptable user experience Reduce troubleshooting complexities associated with existing environments Avaya Desktop Video Device 2011 Avaya Inc. All rights reserved. 20

21 Example: Business Collaboration Route directly across the Virtual Services Fabric with IP Shortcuts No need to configure any IGP on any Policy allows redistribution control of IP routing over Fabric Aura Collaboration Server for the Flare Experience 2011 Avaya Inc. All rights reserved. 21
