Fara reorganizing the addressing architecture

FARA: Reorganizing the Addressing Architecture

Mikko Särelä

30.1.2008


Overview

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


Basic components

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


Assumptions

Assumptions

  • Mobile entities

  • Association naming

    • no global namespace

  • Entity naming

  • End system addresses


Fara reorganizing the addressing architecture

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


Fara cont

FARA cont.

  • Forwarding directives

  • Slots

  • Protocol Stack


M fara

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


Conclusions

Conclusions

  • Generalized architectural description

  • Drawbacks: No multicast support
