FTTH = Fiber to the home...
then you'll be
increasing the size
of the last-hop MTU without increasing the MTUs on
intermediate hops, so
you won't gain much. Might be more important to preserve the
1500 byte
The reason to increase the MTU anywhere in the network must originate
from the edge at some point in time. 802.3ah is the single most
important innovation in the edge of the network since G.983. This is
why we have to start somewhere. Why should all IPv6 stacks in the world
support 4 Gig MTU's if its never going to be used outside of
supercomputing labs?
