15
What Challenge Does SDN Really Address?
For Starters – It’s not about the technology, but the
application!
Secondly, even though two large players want to
make us believe it, SDN is not solely about DC
automation
So then, what is the problem?

Fabric Extend
Concept
Fabric Extend enables the extension of Avaya’s Fabric Connect fabrics over third party transport
networks
Introduces new Software logical IS-IS interface capability
Native support on the VSP 8200 and 8400. Support via a external ONA-100 for the VSP 4k *.
IP connection MTU requirements: at least 1584 bytes support for transport network.
Benefits
Allows extending SPB/Fabric Connect over an IP network
or 3rd party enterprise core to enable a unified fabric. IP
network can be campus backbone or MAN/WAN IP MPLS network.
Full fabric capabilities remain in tact over IP
Support for Hub and Spoke topologies
Can also be leveraged to extend Fabric Connect
network over VPLS WAN service.
Allows extending IST over WAN solution with vIST
Positioning
DC – DC Interconnects
Fabric “Islands” interconnect in campus networks
Fabric Connect to Branch Offices via IP based WAN
Timelines& Requirements
Requires: VOS Release 5.0 – mid 2015
Requires: Premier Switch Software License
Requires: Tunnel Manager (COM or SOM)
Trials starting end of Q2 CY15

General Challenges
Number of mobile devices and IoT devices is mushrooming with no end in sight
Fixed wired device mobility without requirement for complex pre-provisioning of access ports
Operational complexity
Security concerns
Need for granular device categorization and policy based isolation of devices and service categories
Regulatory and data privacy requirements (depending on specific environment and regulation)
Security risks arising from old / embedded OS on some devices, for example in medical, industrial and
utility environments
