1. Summary&Conclusions 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, C^3 Multipath, multi-radio, distributed MIMO Mpls LSRs Etc etc etc - so what is the Computer Science instantiation of this architecture

5. 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 that…I havnt got a clue :-)
