Question 16/11 – Protocol procedures relating to specific services over IPv6

(New Question approved on 11 June 2012)


Whereas the global exhaustion of IPv4 addresses is forcing a transition to IPv6, and whereas significant differences exist between IPv4 and IPv6, how to guarantee the service continuity becomes more and more important for the service providers. New protocol procedures may be required to enable implementation and deployment of the services over IPv6 (e.g., wired broadband, IPTV etc.).


Study items to be considered include, but are not limited to:

  • What existing ITU-T Recommendations need updating to take advantage of IPv6?
  • What new services can be identified for which the introduction of IPv6 is a necessary precondition?
  • What new protocol procedures are required to implement services identified above?


Tasks include, but are not limited to:

  • Review existing Recommendations for implicit or explicit dependency on IP version, and update where necessary to provide for a successful transition to IPv6 (working with the relevant Study Groups/Questions)
  • Identify services for which new protocol procedures are required for the transition to IPv6
  • Develop new protocol procedures for the services identified above.



  • Y.2053, Y.2054 and Q.33xxi-series


  • Q1/11, Q2/11, Q3/11, Q4/11, Q5/11, Q7/11

Study Groups:

  • ITU-T SG 13 on NGN (especially Q1/13, Q3/13, Q4/13 and Q7/13)
  • ITU-T SG 16 on multimedia services and applications
  • ITU-T SG 2 and other SGs working on IPv6 issues

Standardization bodies

  • IETF, Broadband Forum,
