6 Representing & Identifying Things Maurizio Dècina, Internet del futuro, Roma La Sapienza, 22 maggio Any Virtual Object is addressable Every Virtual Object can be dynamically associated to a User Identity Every user can have control over a specific virtualized object or aggregation of objects For each Real Object there is a representation in the cloud for duplications, synchronization, re- creation of the object, etc. Actions and events on the Real Object act on network images and clones, and vice versa Source: Dion Hinchcliffe, 2008 URI type format Web markup HTML, XHTML Data XML, ATOM, JSON Images JPG, SVG, PNG Video MPEG, AVI, H.264 Code Jsvascript, SWF WOA/Client Interact via HTTP An Individual, Uniquely Addressable Resource Web- Oriented Architecture (WOA) Resource Examples : Web page Customer Orders Products Blog posts Stock quotes Geolocations Map tiles Headshots Call records Podcasts Ajax components Web widgets Advertisements OpenOffice docs Non exhaustive list of possible representations Links (URIs) to globally unique resources, in lieu of copies

21 Distributed Hash Table - DHT Chord: Query Routing Maurizio Dècina, Internet del futuro, Roma La Sapienza, 22 maggio Properties – Routing table size O(log(N)), where N is the total number of nodes – Guarantees that a file is found in O(log(N)) steps Routing Rule Upon receiving a query for item id, a node – Checks whether stores the item locally – If not, forwards the query to the largest node in its successor table that does not exceed id, or that is equal or immediately greater than id i id+2 i succ Succ. Table i id+2 i succ Succ. Table i id+2 i succ Succ. Table i id+2 i succ Succ.
