Change Is Pervasive; So Too The Network
With change pervasive, the network cannot be immune…
 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..?

Compute Access ≠ User Access
Consolidation & Chaos Theory combine into a perfect storm…
 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

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

Evolution of the Data Center
Once, Campus-class was good enough
What this meant:
Traditionally:
The North-South
to East-West ratio
has been 80:20
– Application traffic traverses
multiple Switch hops – AccessCore-ToR-Server-Core-Access
– Core & Uplinks were more
important than capacity between
Racks
Top-of-Rack
Switches
Racked Servers

Avaya Distributed Top-of-Rack
Delivering the Cloud-grade difference
Now this means:
The future:
East-West traffic
will dominate Data
Center traffic –
‘the new 80%’
– Server-to-Server, Rack-to-Rack
traffic dramatically increases
– Inter-Rack capacity is now
crucial
– Traditional designs introduce
significant latency and degrade
application performance
Top-of-Rack
Switches
Alternatives introduce
latency & congestion,
additional equipment,
consume more ports
Distributed ToR
delivers the
industry’s only lowlatency solution

seamless extension across the Data Center
Business Requirement:
With Fabric Connect:
 Provide direct end-to-end
connectivity at Layer 2 between
applications running on multiple
servers
 Application VLANs mapped into
unique VSNs
 Facilitate live migrations to support

support & maintenance
 Span L2 connectivity throughout
the Data Center, and across
multiple locations
© 2013 Avaya Inc. All rights reserved.
 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
18

Layer 2 Virtual Service Network
Mapping a Layer 2 VLAN into a Virtual Service Network to deliver
seamless Wi-Fi connectivity across the campus
Business Requirement:
With Fabric Connect:
 Provide Wireless Guest Access in
specified locations throughout the
Campus
 Wireless Guest VLAN mapped into
VSN maintains traffic separation
 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 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
19
Use Example: Multi-Tenant Networks
Layer 3 Virtual Service Network
Mapping a Layer 3 VRF into a Virtual Service Network to deliver seamless
Layer 3 extensions through the network
Business Requirement:
With Fabric Connect:
 Provide infrastructure to support
multiple different customers
(airport, education, government)
 VRFs create traffic separation
which is maintained through VSN
 Extends Layer 3 VRFs across the

security
simple and efficient
 Offer dynamic network to
accommodate geographic location  Mitigates: complexity of
configuration, difficulty in providing
changes for network connectivity
resiliency, excessive equipment
 Share common resources where
applicable (e.g. UC)
