  1. FARA: Reorganizing the Addressing Architecture Mikko Särelä 30.1.2008

  2. Overview • New organization of concepts of naming and routing • General architectural model: FARA • Forwarding directive and association architecture • Defines a class of architectures; a conceptual framework • Avoids overloading of identities and topological locations • separation of location and identity • without a new global namespace

  3. Basic Components • Entity • generalization of an application that is an end-point in communications • smallest unit that can be mobile • Association • logical communication link • roughly analogous to transport layer connection • Association Id AId • Communications substrate • below the line - above the line divide • Forwarding Directive in header - part of the API

  4. Assumptions • Mobile entities • Association naming • no global namespace • Entity naming • End system addresses

  5. FARA • Creating an association • Rendezvous mechanism • FARA directory service • End to end security • Communication substrate mechanisms • Packet delivery • FD management • Delivery failure notification • Resource control • Network-layer security

  6. FARA cont. • Forwarding directives • Slots • Protocol Stack

  7. M-FARA • Multiple domains • separate addressing per domain • two level domain hierarchy • (FDup, FDdown) • FD maintenance • M-agents • Associations • simple • connected • mobile • reliable • Prototype • IPv4 and IPv6 domains

  8. Conclusions • Generalized architectural description • Drawbacks: No multicast support
