Re: [802.3ae] 10GbE WAN PHY vs. GFP
Tae Kyu
Kang,
There is a radical difference between 10GbE of all types and
GFP. The coding scheme used for GFP was rejected for use in
10GbE. GFP is for use in mapping all sorts of non-transmission
based protocols, not just Ethernet, into a transmission infrastructure
overhead. 10GbE WAN PHY already has the transmission infrastructure
overhead. GFP is un-needed to support 10GbE when the WAN PHY is
used.
Thank you,

What's
the main difference between 10GbE WAN PHY(WIS) and
GFP(Generic Framing Procedure)
?
I think GFP is similar to WIS
function.(GFP have the WIS function)
Does 10GbE Std. adopt GFP in WAN PHY
?
