Hi All,

This is a useful document for DC operators as well as SPs that are
operating data centers. And I would like to support this adoption.

With the following comments,
1. title of section 2, "Hash-based Load Distribu tion in LAG/ECMP", you
might need to remove the space within 'distribution'
2. For Section 3.1.1., there is a short discussion about flow
identification of several tunneling protocols, VXLAN, NVGRE, etc, I expect
more description of the challenges and problems for these protocols as they
are happening with the DC, e.g., mapping of the overlay flow pattern to the
physical layer, could be a useful guidance for those who are operating
these tunnel.

Best regards,
zhen
