Huawei optical transport

Everyone, I was curious if anyone has used Huawei Optical transport. We are looking at OptiX OSN 6800A to upgrade our backbone to 10G. Pro's and Con's would be great if anyone has used the platform. Thanks, Jeremy

Conclusion: Smart hands in NYC area and new: Tokyo
by Elmar K. Bins 06 Aug '09

06 Aug '09

Hello altogether, I got a couple of freelancers and a few tips which companies to use. I thought I'd at least share the company recommendations, of which I'll have the bosses pick. One other thing - I'll be needing the same thing in Tokyo by the end of the year. If anyone has recommendations, please don't hesitate. I'm not shy of travelling, but I'd rather save time and money there... Yours, Elmar.

Do you aggregate?
by Zartash Uzmi 06 Aug '09

06 Aug '09

Hi all, I hope most people on the list look at the routing table analysis reports. Excerpt from last week show about 292961 prefixes which after maximum aggregation can be reduced to 138493. I wonder how many of you do actually aggregate? If so, do you aggregate manually or using some algorithm? In either case (manual or automatic aggregation), how frequently do you aggregate? more frequent than the BGP updates frequency? If you aggregate, do you announce the aggregated prefixes or the original un-aggregated prefixes? how big is your network? (Tier-1, 2, 3, campus, etc.) I am hoping to get a few answers :) Regards, Zartash
