Re: Recent NTP pool traffic increase

Prepending with another ASN you don't own

Is it acceptable to prepend using another networks ASN as long as your ASN is the last one in the path? I can think of a few scenarios where this is helpful. One scenario: Anycast content provider with an ISP (who you aren't directly peering with) is choosing to send all traffic to a PoP on

Re: Wanted: volunteers with bandwidth/storage to help save climate data

Surfing through the links - any hints on how big these datasets are? Everyone's got a few TB to throw at things, but fewer of us have spare PB to throw around. There's some random #s on the goog doc sheet for sizes (100's of TB for the landsat archive seems credible), and there's one number that

Re: Wanted: volunteers with bandwidth/storage to help save climate data

It would seem like the more copies the better, seemingly chunking this data up and using .torrent files may be a way to both (a) ensure the integrity of the data, and (b) enable an additional method to ensure that there are enough copies being replicated (initial seeders would hopefully retain the

Re: Multicast IPTV on DOCSIS

Yes it works over docsis, you assigned downstreams to part of a multicast group and the CMTS will use those when a device asks to join. X1 is both traditional HFC and also full on IPTV which is where everyone is going including HFC plants. Mediaroom is the least popular middleware when

Re: Prepending with another ASN you don't own

Even in that case I believe you should encapsulate between two instances of your own ASN. Your example follows this but the text says only about the last one in the path, while having both last and at least one previous is better since you won't be implying that some other AS has connection to yet
