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


  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!

  Rachel

   

   

  Best Regards!
