1. The Internet has a great future behind it.
Jon Crowcroft,

2. Communications Research Strategy
Too long trying redo Internet success
Both CS&EE programs of research
Give up & Admit it was serendipity
What alternative Strategies?
To retain funding/momentum
Engage new people

3. Evolution versus Revolution
Rexford & Dovrolis argued in /
Deployment is not a research goal
But problems from internet do inspire
But clean slate is also inspiring…
Also look at deployment timescales
I co-led IPng requirements 22yrs ago
We only now see 15% of net runs IPv6

4. Top down versus Bottom up
Top down initiatives rarely work
Arpanet is not repeatable,
Wasn’t the Internet as we know it anyhow
That came out of much smaller groups
Really skunkworks/stealth
Fire/FIND/Geni etc…..hmmm
Doesn’t engage people thinking out of the box
Much, because competitive funding mostly…
...goes to same 5 places....

5. Problem versus Challenge led 1.
Change link/net/transport or
Solve accountability when needed
Change net
Solve mobility as needed

6. Problem versus Challenge led 2.
Data Center Networks
Latency bounding
Routing Scaling
Iot
Availability
security

7. Problem versus Challenge led 3.
Inherent in 5G
Capacity – massive mimo, coop relay etc
Availability, security
Wireless tech, not IP level?
Not obvious – e.g. net coding
Interdomain/multiprovider
But IP failed to deliver scale here
For IoT or Data Centers
So why do you expect it to save 5G?

8. Layer Violation&Appropriation
Rebuilding IP at three layers is a bad idea
Just as ATM (ABR) was a bad mix with TCP CC

9. Communities of interest/expertise
UK suffers from few EECS departments
NGN v. Commnet2 split not just cultural
Build on existing communities
Organise joint event (inject
Engage or ignore?
Parallel play
Throw challenges over the fence at each other
True Engagement
Help me out here – some examples
Perhaps scaling interdomain
Or wireless security?
Priv (traffic anal)&ddos prob. esp.

10. Funding Programmes
Parallel play: throw challenges over the fence at each other
Then do joint bids for joint problem, e.g.
Coding
Crypto
Massive multipath
More close Engagement
Help me out here – some examples:
Perhaps scaling inter-domain routing for 5G
Or wireless security for 5G IoT++?
Accountable
Privacy v. traffic analysis
Ddos resistance prob. Especially for BCP38

11. Time for something else?
Suggestions from what you find hard
Debugging net
With Isolation at all levels
With ultra fast mobility
Sustaining net
With 1 billion devices per city
1% broken at any given time

12. Networked Machine Learning #1
ML is Analytics
Ignoring deep learning/NN (for now)
Analytics runs on hadoop or spark
In a data center –
“embarassingly parallel”
Main tricks are to cope with node outage
Needs low latency (barrier synch phase)
What if wide area networked ML?

13. Networked Machine Learning #2
For example, 1 billion personal clouds
Smart home hub holds human data
User offers it to service provider
E.g. power consumption/device
To electricity provider
in exchange for money/discount
In a privacy preserving way
How does EDF run ML on 1 billion small nodes?

14. Networked Machine Learing #3
Can run on smart city, transport, etc
+Can run on network monitoring itself
Needs low latency, synch, replicas
In presence of multi-path, fails, etc
Needs to work multi-domain
Where multi=10^9
So what does this look like?
No real idea – c.f.
