Mingui,

Are you familiar with the english (maybe just american) expression
"grabbing at straws"?

I think datacenter interest in Trill and SPB is declining,
particularly in very large datacenters where scaling limits are being
felt.  The current chaos in datacenters revolves around SDN, or more
precisely at this point, arguing about what SDN is and isn't.
