  1. Diameter Group Signaling –Progress towards a suitable Solution M. Liebsch IETF82, TaipeiDiameter Maintenance and Extensions (DIME) WG 17th November 2011

  2. Scope of the solution document Specify the following components: • Formatof bulk/group signaling message(s) • Grouping of users and associated attribute-value pairs • Mechanisms and Operation for bulk operations Opt for.. • Description of use cases coming along with the specification document

  3. Format of commands • Analysis of different practices done since IETF81 • Dedicated new bulk operation command for selected existing commands • Generic and new bulk operation command • Use existing messages, indicate bulk operation within the message • Practices assessed according to.. • Ease of implementation and deployment • Flexibility • Extensibility

  4. Grouping of users and context • Representation of groups • Static • Dynamic • Role of per-user IDs • Session-ID • Identification of groups • Group ID • List of Session IDs • Encoding of options to include group and context information into bulk commands

  5. Grouping APVs for bulk signaling(in the order of efficiency and example for discussion) • Group-ID identifies multiple users, list of attributes/values applies to all users of the group • List of Session-IDs identifies a group of users, list of attributes/values applies to all users of the group • List of Session-IDs identifies multiple users, each Session-ID has an individual list of AVPs associated Diameter Hdr [Session-ID] AVP 1 AVP 2 AVP N Group-ID Diameter Hdr [Session-ID] AVP 1 AVP 2 AVP N Session-ID 1 Session-ID K Diameter Hdr [Session-ID] Session-ID 1 AVP 1.1 AVP 1.2 AVP 1.N Session-ID K AVP K.1 AVP K.2 AVP K.N

  6. Next Steps • Formulate and agree on charter text • Agree on milestones • Single document considered sufficient • Converge on solution and move towards WG document
