Devices Are ChangingAlmost nothing in common, except that they’re all different…

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…

Compute Access ≠ User Access
Data Center presents is a very different scenario to the Wiring Closet
It's virtually unknown for Desktop ports to operate anywhere near line-rate
Top-of-Rack Switch: it is altogether feasible to talk of Servers running 10 Gigabit ports at or near line-rate
Consolidation & Chaos Theory combine into a perfect storm…

“By 2014, network planners should expect more than 80% of traffic in the
Data Center's local area network to be between Servers.”
Your Data Center Network Is Heading for Traffic Chaos

Evolution of the Data CenterOnce, 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

Avaya Distributed Top-of-RackDelivering 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-RackSwitches
Distributed ToR delivers the industry’s only low-latency solution
Alternatives introduce latency & congestion, additional equipment, consume more ports

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

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. 2020
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

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

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
