Potential new areas of activities

  • WP1 (services and application requirements &control protocols)
    • Multi-media related Network control requirements
    • NGN control architecture (functional decomposition)
    • NGN interfaces & control protocols (APIs, SIP …)
  • WP2 (call/session and resource control requirements)
    • Resource and QoS control functions
  • WP3 (signalling/control protocols)
    • Protocol selection and profile for call/session/bearer (SIP, MPLS, RSVP, COPS …)
    • Call/bearer control protocol interactions & interworking
  • WP4 (transport of control protocols)
    • Signalling transport architecture and protocol profiles (e.g. based on SIGTRAN RFCs)

  • Per Session Control Protocols:
  • Session (call): 1
  • Service/Application: 2
  • Resources allocation & traffic policy control: 2, 3

Session (or call)

control (Call Agents)

E.g. BICC, H323, SIP, SIP-T/SIP-GTD

3

e.g. H248

Resource control &

Traffic policing

Bearer

control (Switch/Routing)

E.g. ATM sig, MPLS/RSVP ...

  • Transport resource control:
  • Bearer/Connection control: 4
  • Backbone resource control: 5, 6

5 (UNI)

6 (NNI)

Transport

(xDSL/GbE/SDH/DWDM/Optical)

E.g. GMPLS with RSVP-TE

or CR-LDP, or Optical-PNNI

slide4

Next steps ...

  • Confirmation of SG11 as the UIT-T study group lead on Network Control Architectures & Protocols
    • legacy and emerging ones for NGN architectures
  • Initiation of a SG11 ‘N2CAP’ project
    • Part of the NGN 2004 SG13 coordinated Project
  • Organise its preparation & launch
    • e-mail activity (moderated by the Project coordinator)
  • Impacts on the SG11 Questions and Structure
    • SG11 Questions update
    • SG11 structure adjustments possibly needed
