Summary

SummaryConclusions of Clean Slate

• Stacks v. Heaps
• Role Based Architectures, Control Plane
  deconstruction of layers
• Virtualisation
• Software v. hardware
• Declarative/metarouting
• high level languages for systems on networks
• Privacy preserving network measurement
• Distributed or in archives
• Radical Wireless Net stuff
• Power saving - need more info on traffic
• Mobility - use vehicular info to trade-off
  differently
• See next
• Can people send me slides to dist to attendees
• Do we mind putting agenda/attendee (NOT email of
  course)
• and/or slides on web?
• Who needs the bus (6.30) - or walk to castle,
  then jesus (now)?

2
Adjacency - what is a network (graphs, queues,
links etc)???

• Jon. Crowcroft
• Computer Lab
• University of Cambridge

3
Shared Media v. Pt2Pt v. Switches (NBMA) etc etc

• Wireless Mesh (multiple overlapping mesh and
  radio?)
• And Packet v. Connection v. (say) swarms (see
  later)?
• There is no connection
• How to build a testbed
• What are the interesting questions?

4
clouds

• Net folk often draw clouds - this is not a crazy
  abstraction
• Encapsulate a notion of useful adjancy
• Usefulness defined by
• Community (policy in AS sense)
• Reachability (in same comms protocol role/layer
  sense)
• Information rate (e.g. spectrum, or lambda) (SIR
• Can recurse/nest, or merge/split
• Spectrum management for incumbent, community
  mesh, C3
• Multipath, multi-radio, distributed MIMO
• Mpls LSRs
• Etc etc etc -
• so what is the Computer Science instantiation of
  this architecture

Swarms (tm)

• Is my mad idea to replace packets and circuits
  with
• A pure network layer version of bittorrent
• Using cross layer net coding (if needed)
• No sender/receiver
• Pub/sub or event/notify, but as first class net
• ADU is net object (e.g. in end system, but also
  in net)
• (e.g. imagine rabin fingerprint/coded object
• being net coded in XORS in the air sense
• Or 10Mbyte or 1Gbyte MTU/MSS packet in photonics
  case

6
Questions?

• Cloud is a fuzzier notion of a net than a Set
• Basically, convolves performance AND reachability
• I.e. like a potential well w/ depth
• Other than thatI havnt got a clue -)
