All rights reserved. 6 Change Is Pervasive; So Too The Network Tomorrow’s application requirements are so different from yesterday’s Traffic patterns are evolving with the emergence of mobile, video, & embedded Why then, do most vendors offer products and solutions that are geared, and can only be deployed, as if nothing has changed..? With change pervasive, the network cannot be immune…

All rights reserved. 9 Evolution of the Data Center Once, Campus-class was good enough Racked Servers What this meant: –Application traffic traverses multiple Switch hops – Access- Core-ToR-Server-Core-Access –Core & Uplinks were more important than capacity between Racks Traditionally: The North-South to East-West ratio has been 80:20 Top-of-Rack Switches
© 2013 Avaya Inc. All rights reserved. 10 Avaya Distributed Top-of-Rack Delivering the Cloud-grade difference Now this means: –Server-to-Server, Rack-to-Rack traffic dramatically increases –Inter-Rack capacity is now crucial –Traditional designs introduce significant latency and degrade application performance The future: East-West traffic will dominate Data Center traffic – ‘the new 80%’ Top-of-Rack Switches Distributed ToR delivers the industry’s only low- latency solution Alternatives introduce latency & congestion, additional equipment, consume more ports Racked Servers

© 2013 Avaya Inc. All rights reserved. 18 Mapping a Layer 2 VLAN into a Virtual Service Network to deliver seamless extension across the Data Center Use Example: Virtual Machine Migration Business Requirement: Provide direct end-to-end connectivity at Layer 2 between applications running on multiple servers Facilitate live migrations to support application scaling and hardware support & maintenance Span L2 connectivity throughout the Data Center, and across multiple locations Layer 2 Virtual Service Network With Fabric Connect: Application VLANs mapped into unique VSNs VSNs extends L2 connectivity across the Fabric Provisioning only at Fabric edge Mitigates: many touch points for configuration, management, & troubleshooting, Broadcast domain seen at all points through the network, lack of traffic isolation
© 2013 Avaya Inc. All rights reserved. 19 Mapping a Layer 2 VLAN into a Virtual Service Network to deliver seamless Wi-Fi connectivity across the campus Use Example: Wireless Guest Services 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 Guests required for compliance and security tracking Layer 2 Virtual Service Network With Fabric Connect: Wireless Guest VLAN mapped into VSN maintains traffic separation Layer 2 VLAN extension across the Fabric Provisioning only at Fabric edge Mitigates: many touch points for configuration, management, & troubleshooting, Broadcast domain seen at all points through the network, lack of traffic isolation
© 2013 Avaya Inc. All rights reserved. 20 Use Example: Multi-Tenant Networks Business Requirement: Provide infrastructure to support multiple different customers (airport, education, government) Maintain traffic separation between customers for data integrity & security Offer dynamic network to accommodate geographic location changes for network connectivity Share common resources where applicable (e.g. UC) Mapping a Layer 3 VRF into a Virtual Service Network to deliver seamless Layer 3 extensions through the network Layer 3 Virtual Service Network With Fabric Connect: VRFs create traffic separation which is maintained through VSN Extends Layer 3 VRFs across the Fabric Use of shared services becomes simple and efficient Mitigates: complexity of configuration, difficulty in providing resiliency, excessive equipment
© 2013 Avaya Inc. All rights reserved. 21 Use Example: Workgroup Networks Business Requirement: Provide network access for a common set of users (department, agency, contractors, etc.) Maintain traffic separation 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 VLANs across Campus to achieve this Extending SPB by delivering a policy-based Layer 3 internetworking between multiple Virtual Service Networks Inter-VSN Routing With Fabric Connect: 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 Mitigates: many touch points for configuration, lack of isolation of traffic
© 2013 Avaya Inc. All rights reserved. 22 Use Example: Business Collaboration Business Requirement Deploy new business collaboration services 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 Direct IP Routing across the Fabric without the need for any additional IGP or even Virtual Service Network configuration IP Shortcut Routing With Fabric Connect: Route directly across the Fabric with IP Shortcuts No need to configure and IGP on any VLANs Policy allows redistribution control of IP routing over Fabric Mitigates: complexity of configuration, difficulty in providing resiliency, lack of isolation of traffic, providing appropriate quality-of- service
