Re: [OPSAWG] WG last call for "Mechanisms for Optimal LAG/ECMP Component Link Utilization in Networks"

Hi,

I apologize for the one day delay in sending this review. Vacation interfered. 

I read the document and I have a basic unclarity. Hopefully it is just me, and maybe some clarification text and references to be added. 

What does this document exactly refer to when saying 'LAG/ECMP techniques'? Is this either LAG (layer 2) or ECMP, or a combination of the two, or all of these? There is no reference at all in the document for LAG, no solid reference for ECMP (2992 only refers to 'an ECMP algorithm'). 

I also had a hard time finding the sFlow references. In desperation I went to wiki http://en.wikipedia.org/wiki/SFlow which kindly informed me that 

> sFlow is a technology for monitoring network,[1] wireless[2] and host[3] devices. The sFlow.org consortium[4] is the authoritative source for the sFlow protocol specifications.[5] sFlow version 5 is the current version of sFlow. Previous versions of sFlow, including RFC 3176, have been deprecated.[6]

This seems problematic. RFC 3176 has no mark of being 'deprecated' in IETF terms anyway. 

Regards,

Dan
