1. FARA: Reorganizing the Addressing Architecture
Mikko Särelä

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 Association Communications substrate
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 Entity naming
no global namespace
Entity naming
End system addresses

5. FARA Creating an association End to end security
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 FD maintenance Associations Prototype
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
