Applications Are ChangingTransition from Client/Server to Web 2.0 & Cloud…


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


Roles Are ChangingThe traditional workplace is disappearing…


People Are ChangingExpectations are different, expectations are higher…


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

Gartner


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

Top-of-RackSwitches


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

Empowering the Cloud

Mapping of Layer 2 VLANs into Virtual Service Networks delivering seamless Layer 2 extensions

Layer 2 Virtual Service NetworksVirtual Service Network

Mapping of Layer 3 VRFs into Virtual Service Networks delivering seamless Layer 3 extensions

Layer 3 Virtual Service NetworksVirtual Service Network

Policy-based Layer 3 internetworking capability between multiple Virtual Service Networks

Inter-VSN Routing

Virtual Service Network

Virtual Service Network

Direct IP Routing without the need for Virtual Service Networks (or any additional IGP)

IP Shortcut RoutingVLAN VLAN


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


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



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


Use Example: Multi-Tenant Networks


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



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


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


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


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
