  "abstract": "This document describes how to adapt the Session Description Protocol (SDP) to express one or more source addresses as a source filter for one or more destination \"connection\" addresses. It defines the syntax and semantics for an SDP \"source-filter\" attribute that may reference either IPv4 or IPv6 address(es) as either an inclusive or exclusive source list for either multicast or unicast destinations. In particular, an inclusive source-filter can be used to specify a Source-Specific Multicast (SSM) session. [STANDARDS-TRACK]",
