Where are things moving? SDN Interesting SDN applications Support more technologies Improved controller design Cross-layer optimization
3
SDN applications SDN Interesting SDN applications
4
SDN applications – BGP free core Complicated to configure Complicated to manage Expensive devices
5
SDN applications – BGP free core Apply SDN! Similar to demo, but BGP Single BGP node Cheap devices RouteFlow project http://cpqd.github.com/RouteFlow
6
SDN applications – BGP free core Lots and lots of entries Can we reduce the memory requirements?
7
SDN applications – BGP free core Normally, full forwarding tables everywhere What if we split the forwarding table and distribute it?
8
SDN applications – BGP free core Cleverly split the forwarding table into multiple pieces Install to switches, add tunnel magic Dramatic reduction in memory Slight increase in delay
9
Where are things moving? SDN Improved controller design
10
Improved controllers - Abstraction Earlier we mentioned abstractions, but how? Abstract a whole network to a single node Scalability, simplicity Combine nodes into one Grow single nodes, “super-nodes”
11
Improved controllers - Abstraction Need something similar as in the BGP free core example But how can we do it for full OpenFlow rules?
12
Where are things moving? SDN Support more technologies
13
Support more technologies - Opto Basic support for Optical nodes more or less done Simple wavelength setup Not a big gain compared to existing systems
14
What if we add support for basic monitoring (e.g. BER) Much simpler with the SDN approach Detect degradation, reconfigure network
15
Add support for modifying physical parameters (like modulation) Tune network based on monitoring input Again, the SDN approach makes it easier
16
More physical parameters! Tune modulation format, spectral width, based on current demand
17
Where are things moving? SDN Cross-layer optimization
18
Highly reconfigurable link technologies (both opto and radio) More dynamic routing schemes How can we combine these to optimize for: Latency, throughput, energy efficiency? Cross-layer optimization
19
The end! Any of this sounds interesting? We’re looking for partners, e.g. FP7 call 11 in Spring 2013 Any questions? Pontus.skoldstrom@acreo.se, Anders.gavler@acreo.se Pontus.skoldstrom@acreo.seAnders.gavler@acreo.se Wolfgang.john@ericsson.com Elisa.bellagamba@ericsson.com Thanks for listening!
