A new IETF working group has been proposed in the Real-time Applications and Infrastructure Area. The IESG has not made any determination as yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg@ietf.org) by May 22, 2008. Data for Reachability of Inter/tra-NetworK SIP (drinks) ------------------------------------------- Last modified: 2008-05-14 Current Status: Proposed Working Group Chairs: TBD Area Directorate: Real Time Applications (RAI) RAI Director(s): Jon Peterson jon.peterson@neustar.biz Cullen Jennings fluffy@cisco.com Mailing Lists: peppermint@ietf.org General information about the mailing list is at: https://www1.ietf.org/mailman/listinfo/peppermint Description of working group: The IETF has been working on various aspects of SIP-enabled Multimedia administrative domains among SIP Service Providers (SSP's). SSP's are entities that provide session services utilizing SIP signaling to their customers. In addition, the IETF has done significant work on data exchanges among various network elements. The ENUM and SPEERMINT working groups provide the underlying context for much of the intended work that the DRINKS working group will undertake. The ENUM working group is specifically chartered to develop protocols that involve the translation of E.164 numbers to URIs. While the SPEERMINT working group has been chartered to develop requirements and best current practices among real-time application SSPs and to describe how such services may best interconnect across administrative boundaries. Specifically, DRINKS will provide details of how Session Establishment Data (SED) is collected, what comprises SED, how SED should be used to properly identify an optimal path to a destination SIP user agent (UA), either internally or externally to the SSP. For the initial iteration of this charter, the SED data is assumed to be fields that might be provisioned for ENUM, with limited exceptions. If the working group would like to work on data types unrelated to ENUM registries and databases, the WG will recharter. In addition DRINKS will ensure that the SED and the SIP session data securely exchanged between the peering functions. Typical SED data might include: + Routes - Destination SIP/SIPS/TEL URI Egress and Ingress Routes - Relevant route names, identifiers, and services - Attributes affecting route selection - PSTN database information + Targets - Individual, ranges, or groups of user-agent identifiers - Target aggregation entities (e.g. service areas) and target-to-aggregate associations + Treatment Profiles - Priority - Location Potential SED Data types not in scope will be session rating or other billing or pricing information between SSP's. It is also recognized that peering relationships become more complex as multiple peers are added to a common relationship; these complex aspects and requirements are defined within the contexts of a peering Federation. The DRINKS working group is chartered with a scope that is orthogonal to SPEERMINT and ENUM. The protocol work of DRINKS will be designed to build from the work of SPEERMINT and ENUM to identify and define the data structures and data exchange protocol(s) among SIP based Multimedia administrative domains. These administrative domains may be of any practical size and could be any type of SSP, such as recognized telephony carriers, enterprises, end-user groups, or Federations. Data exchanges among these administrative domains may be bi-lateral or multi-lateral in nature, and could include bulk updates and/or more granular real-time updates. Administrative domains may exchange data directly between each other or might use an external registry to aggregate data from multiple administrative domains or multiple data providers into a single view. The working group will draw upon expert advice and on-going consultation from the ENUM and SPEERMINT working groups, and also the XML Directorate. The working group will consider the reuse of elements of RFC 4114. The final work product(s) from this working group will utilize and be based on XML documents and XML document exchanges. GOALS AND MILESTONES Nov 08 - WGLC for Requirements for Session Establishment Data (SED) data exchanges (Proposed Standard).

Mar 09 - WGLC for Exchange of Session Establishment Data (SED) from registries to Location Routing Function databases (Proposed Status). Apr 09 - IESG Submission for Exchange of Session Establishment Data (SED) from registries to Location Routing Function databases. _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
