Data for Reachability of Inter-/Intra-NetworK SIP (DRINKS)
Use Cases and Protocol Requirements
Abstract
This document captures the use cases and associated requirements for
interfaces that provision session establishment data into Session
Initiation Protocol (SIP) Service Provider components to assist with
session routing. Specifically, this document focuses on the
provisioning of one such element termed the "registry".

1. Overview
[RFC5486] (Section 3.3) defines Session Establishment Data, or SED,
as the data used to route a call to the next hop associated with the
called domain's ingress point. More specifically, the SED is the set
of parameters that the outgoing signaling path border elements (SBEs)
need to establish a session. However, [RFC5486] does not specify the
protocol(s) or format(s) to provision SED. To pave the way to
specify such a protocol, this document presents the use cases and
associated requirements that have been proposed to provision SED.
SED is typically created by the terminating or next-hop SIP service
provider (SSP) and consumed by the originating SSP. To avoid a
multitude of bilateral exchanges, SED is often shared via
intermediary systems -- termed "registries" within this document.
Such registries receive data via provisioning transactions from SSPs,
and then distribute the received data into Local Data Repositories
(LDRs). These LDRs are used for call routing by outgoing SBEs. This
