is about a year ago and my search for a standard largely ended at the I-D you referenced above. However, I did find that Juniper has a proprietary implementation of this draft -- search for mib-jnx-bgpmib2.txt. -Chris -- Chris Tracy Energy Sciences Network (ESnet) Lawrence Berkeley National Laboratory

power just right -- hence the need to re-balance if your aggregate signal changes a lot -- too low and the EDFA would not kick on at all, too high and you'd saturate the amp. -Chris -- Chris Tracy Energy Sciences Network (ESnet) Lawrence Berkeley National Laboratory

s topology) and output of 'lspci -tv' can help you determine the best PCI slot to stick the card into to avoid contention. Some cards support checksum offloading, 'ethtool -S' can often tell you whether that's working or not, etc. -Chris -- Chris Tracy Energy Sciences Network (ESnet) Lawrence Berkeley National Laboratory

Re: 1G/10G options over 130 km of fiber

It would be helpful to know what type of fiber you are working with...SMF-28(e) G.652, NZDSF G.655, ...? You not only need to account for dB loss over the span, but also chromatic dispersion. At 1550nm, you can expect <= 0.22 dB/km for SMF-28 G.652 if you have a nice clean fiber path...possibl
