Any other opinions on this issue? Roni, I understand that your preference for option 2 is not blocking. Am I correct?

And I'll revise the "reserved" field in section 3.2 to 8 bits. Thanks. Best Regards!

However in other XRBLOCK drafts using I field, at least one type of Interval metric flag is used. unlike other XRBLOCK drafts using I field, none of Interval metric flags (from I=00 to I=11) is used in this draft. So I prefer to keep as it does.

There is no other reason Roni From: Qin Wu [mailto:bill.wu@huawei.com] Sent: 10 May, 2013 4:05 AM To: Roni Even; 'Shida Schubert'; 'xrblock' Cc: 'xrblock-chairs' Subject: RE: [xrblock] 2nd WGLC for draft-ietf-xrblock-rtcp-xr-synchronization Hi,Roni: Thank for your comment, if I understand correctly, Initial Synchronization Delay metric Only needs to be reported once, i.e., at the beginning of the session since the value of Initial Synchronization Delay metric usually is fixed and will Not change at each report interval. So I think your 1st option is more straightforward.

It looks OK. I have one comment The "reserved" field in section 3.2 should be 8 bits since the "I" field was removed. Another option is to keep the "I" field and say that it should be ignored Roni Even From: xrblock-bounces@ietf.org<mailto:xrblock-bounces@ietf.org> [mailto:xrblock-bounces@ietf.org] On Behalf Of Shida Schubert Sent: 08 May, 2013 4:56 AM To: xrblock Cc: xrblock-chairs Subject: [xrblock] 2nd WGLC for draft-ietf-xrblock-rtcp-xr-synchronization This is an announcement of a 2 weeks XRBLOCK WG last call on "Report Block for Synchronization Delay and Offset Metrics Reporting" priort o requesting publication of the document as a proposed standard.
