fault pinpointing in case of 10gbe

["Ashwin Kumar .T.C." <kumar.ashwin@xxxxxxxxx>]

Hi All

I have this question regarding how the sanity of the signal i.e, 10gbe
which travels  across lot many networks and ultimately drops as
10gb at the destination Ethernet detected and measured.
SONET uses  the Path AIS and other signalling to pinpoint the error.
But how does the 10gbe take care of this.

The typical case is :

10g ethernet                                10g
ethernet                                                  10g ethernet
------------->Ring with DWDM -------------> Ring with DWDM or
ATM--------------->destination

So in this case how is the error detection done at the destination
Ethernet setup.
Is RMON the answer to this.
Are there any alternatives to this in 10gb e.
What is it in the signal that carries the info regarding the fault and
how is this decoded at the required.
Any pointers to this will be of great help to me.

Thanks & Regards

Ashwin
