Virtualisation of the Service Provider Network will happen
Virtualisation is the next transformative catalyst for the ServiceProvider Network
The purpose of virtualisation todayis to address OpEX
Should we stop there?
No!
Orchestration can extend the impact of virtualisation
It will add capabilities to the Service Provider top line

Characteristic General PurposeCPU
Custom ASIC / NPU
Throughput (BW) Low High (10x)
Performance (pps) Low High (10x)
Power efficiency (Gbps/W) Low High
Integration Effort Low High
Flexibility High Low/Medium
System development
cost & time Low High
Use x86 (General CPU) for control, signalling and high touch, low BW
applications where cost, flexibility and fast development are required
Use Custom ASIC/NPU implementations for high BW, high performance
processing where algorithms are well defined/known

Rules of Thumb
Downside
20% increase in requiredprocessing
Upside
Moores Law Processing doublesevery 36 months
NeilsensLawb/w increases by50% annually
Butters Law - cost per optical bitdecreases by 50% every 9 months
BUT we need to pay attention toWirths law
S/W gets slower more rapidly thanH/W becomes faster

So, yes, it is sustainable ... but
you have to really think about it

What is the relationship of interests?
You hear things like: Your apps are you
And then there are statistics like this ...
48% of users would be less likely to use the app again if its performance isbad
84% of users say app store rating are important in their download and install
decisions
78 % of users expect mobile apps to load as fast as, or faster than, a mobile
