RFC 6958, "RTP Control Protocol (RTCP) Extended Report (XR) Block for Burst/Gap Loss Metric Reporting", May 2013

Source of RFC: xrblock (rai)

Errata ID: 4524

Status: Held for Document Update
Type: Technical

Section 3.2 says:

  Number of Bursts: 16 bits

    The number of bursts in the period of the report (Interval or
    Cumulative).

    The measured value is an unsigned value.  If the measured value
    exceeds 0xFFFD, the value 0xFFFE MUST be reported to indicate
    an over-range measurement.  If the measurement is unavailable,
    the value 0xFFFF MUST be reported.

It should say:

  Number of Bursts: 12 bits

    The number of bursts in the reporting period (Interval or
    Cumulative).

    The measured value is an unsigned value.  If the measured value
    exceeds 0xFFD, the value 0xFFE MUST be reported to indicate
    an over-range measurement.  If the measurement is unavailable,
    the value 0xFFF MUST be reported.

Notes:

This was discussed on the mailing list after the Prague meeting and agreed at the Yokohama meeting.

Block length: 16 bits

      This field is in accordance with the definition in [RFC3611].  In
      this report block, it MUST be set to 4.  The block MUST be
      discarded if the block length is set to a different value.

      This field is in accordance with the definition in [RFC3611].  In
      this report block, it MUST be set to 3.  The block MUST be
      discarded if the block length is set to a different value.

Notes:

The block length is calculated and indicated incorrectly in two places: the packet format and the definition of the block length.

Notes:

The packet format on Section 3.1 shows 12 bits, however
section 3.2 defines the "Number of bursts" as a 16-bit field.

Relevant text from Section 3.2 pasted below:

Number of Bursts: 16 bits

The number of bursts in the period of the report (Interval or
Cumulative).

The measured value is an unsigned value. If the measured value
exceeds 0xFFFD, the value 0xFFFE MUST be reported to indicate
an over-range measurement. If the measurement is unavailable,
the value 0xFFFF MUST be reported.
--VERIFIER NOTES--
There is an error in the report. The reporter will report a new corrected errata.
