Defining the “Problem”

What Challenge Does SDN Really Address?


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?


16

Today’s Enterprise IT Challenges

Financial

Reduction in Capex, OpEx and

Maintenance

Mature Markets

Standardization

Operational

Need for Agility

Faster time to service though simplification

and goals

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

SDN Fx Enabled Device / IoT Mobility and Flow Control

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
