The following errata report has been submitted for RFC8832,
"WebRTC Data Channel Establishment Protocol".

You may review the report below and at:

--------------------------------------
Type: Editorial
Reported by: JC Yan <jc.yan.2003@gmail.com>

Section: 5.2

Original Text
-------------
This message is sent in response to a DATA_CHANNEL_OPEN_RESPONSE
message. It is sent on the stream used for user messages using the
data channel. Reception of this message tells the opener that the
data channel setup handshake is complete.

Corrected Text
--------------
This message is sent in response to a DATA_CHANNEL_OPEN message.
It is sent on the stream used for user messages using the data
channel. Reception of this message tells the opener that the
data channel setup handshake is complete.

Notes
-----
RFC 8832 defines only two message types: DATA_CHANNEL_OPEN (0x03) and DATA_CHANNEL_ACK (0x02). There is no DATA_CHANNEL_OPEN_RESPONSE message defined anywhere in the document. The reference appears in early drafts of the protocol (draft-jesup-rtcweb-data-protocol-00, March 2012), which defined a DATA_CHANNEL_OPEN_RESPONSE (msg_type 1) as a separate message. This seems to have been replaced with DATA_CHANNEL_ACK. Section 6 (Procedures) correctly describes the ACK as a response to the OPEN message, confirming this is an editorial oversight.

Instructions:
-------------
This erratum is currently posted as "Reported". (If it is spam, it
will be removed shortly by the RFC Production Center.) Please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party
will log in to change the status and edit the report, if necessary.
