[xrblock] Proposed change to summary discard draft to address discard type issue

["Huangyihong (Rachel)" <[e-mail]>]

Hi all,

In the last IETF meeting, one open issue of summary statistics draft (http://tools.ietf.org/html/draft-ietf-xrblock-rtcp-xr-summary-stat-00) raised is to add some words to point out discard type chosen. Here  is the proposed text to address this issue.

In section 3.2.2, the description of Gap Discard Rate field, the third paragraph.
OLD TEXT:
"
      where "number of packets discarded" is obtained from the RTCP XR
      Discard Block [DISCARD] and Packets Expected is calculated as the
      difference between "extended last sequence number" and "extended
      first sequence number" (Interval or Cumulative) provided in the
      Measurement Information block [MEASIDENT].
"
NEW TEXT:
"
where "number of packets discarded" is filled with number of packets due to both
early and late to be played out which is obtained from the RTCP XR
Discard Block [DISCARD], and Packets Expected is calculated
as the difference between "extended last sequence number" and "extended
first sequence number" (Interval or Cumulative) provided in the
Measurement Information block [MEASIDENT].
"

Best Regards!
