State assumptions Not mobile code Not dynamic path creation Not doing service discovery Who owns clusters? Assumption valid for large set of applications Expected contribs before outline Harvest -- related work Related work -- Berkeley intensive End of related work -- why rel work don't do what you're doing Next generation portals -- composing services; MS won't do it, Yahoo might State assumptions about business model Criterion for feasibility Throw in other loss characteristics -- uniform... What are the architectural issues -- before design Routing -- lots of details... Problem you're solving -- service instance choice -- motivate this Choice of test sites... Berkeley+UNSW -- too wide Worst-case? Developing prototypes Going to be much more regionalized... Who owns the services? Be very clear about assumptions... Better estimation of the size of overlay. Scalability? Cumulative distbn? Why 4000/5000 nodes? What is the end-product? A little vague? What are you actually going to build? Emulation on millennium? What is the product that is come out? What are the pieces of the architecture? How do you know when you're done? Flow of info between pieces - business model or operational model Characterize end services.. detailed characterization Were'nt enough real examples Music playback -- what is quick recovery? Internet jitter -- vague -- give a reference Cite -- and biblio Backup slides... What are the kinds of optimization metrics? Why rel work does'nt look at this? Have'nt looked at geographically dist indep service providers -- bring that out in the title itself Rel work -- IDMaps How do you manage state? How the big picture related to service providers? Dichotomy between bigger picture and details What are you trying to show in the evaluation? What are the impact of the results Limit the area you cover -- do one thing in depth Research methodology -- too many metrics; some notion of direction Too long on the UDP stuff -- small expt -- less details -- ground it better Evaluation -- should'nt spend too much time on this as well. Rel work -- don't just throw in stuff -- say what's good about them USITS paper -- TRIADS stuff Collapse the related work
