Type name: application Subtype name: trickle-ice-sdpfrag Required parameters: None. Optional parameters: None. Encoding considerations: The media contents follow the same rules as SDP, except as noted in RFC 8840. The media contents are text, with the grammar specified in Section 9.2. Although the initially defined content of a trickle-ice-sdpfrag body does only include ASCII characters, UTF-8 encoded content might be introduced via extension attributes. The "charset" attribute may be used to signal the presence of other character sets in certain parts of a trickle-ice-sdpfrag body (see RFC8866). Arbitrary binary content cannot be directly represented in SDP or a trickle-ice-sdpfrag body. Security considerations: See [RFC 8866] and RFC 8840 Interoperability considerations: See RFC 8840 Published specification: See RFC 8840 Applications which use this Media Type: Trickle-ICE Fragment identifier considerations: N/A Additional information: Deprecated alias names for this type: N/A Magic number(s): N/A File extension(s): N/A Macintosh File Type Code(s): N/A Person and email address to contact for further information: The IESG (iesg&ietf.org) Intended usage: Trickle-ICE for SIP as specified in RFC 8840.
