Ars Technica: "Netflix takes up 9.5% of upstream traffic on the North American Internet"
i wonder why it's acking so much
I read that as 9.5% of traffic leaving NA is Netflix, i.e. foreign users streaming Netflix over VPN
wow
netflix is meant to be coming to new zealand in march
(that's just my interpretation of the headline though)
oh nah
this is about uploading
tcp/ip acks way too much
i wonder if things like ps4 don't do sack or something stupid
hmm it may just be that people aren't uploading much
and it's not a percentage of the total, but of upload in general.
Indeed, that could just be 10% of 1mbps or 10% of 1000gbps, it doesn't say
well skype is uploading more than downloading.
i think it's meant to be of the bandwidth the isp is doing in general.
But skype calls are far shorter and less ubiquitous than netflix
but they also use just as much downstream as upstream
for instance, 4/5 users watch netflix for hours on end, while 1/5 makes a 20 minute skype call
yeah i was more meaning you can't compare percent upload vs percent download
because skype should show in downstream table if that's the case
because it's about 1;1 upload/download
i dont' watch netflix, and talk on skype for more than 20 minutes sometimes.
but i know what you mean
skype is pretty convenient really
there was this idea years ago of doing ack pacing to remove redundant acks on cable networks
because upload was congesting a lot.
and really the whole ack system could do with an update
but no-one wants to break the internet
it would especially help 3g/4g/wireless which are half-duplex though
QUIC may actually help
anybody have experience with vultr?

fink: According to the IRC logs, yes some people do http://irclogger.arpnetworks.com/irclogger_log_search/arpnetworks?search=vultr&action=search&error=0
brycec: cool, thanks
np - I knew I'd heard the name recently
i'll try it out
you get a lot of ram for your buck
i tried it
cos they have sydney location
i'm using up most of the bandwidth on it :(
there's a few annoying things about it
like when doing ubuntu it installs this cloud crap
so i screwed up my bootup, when i was trying to shift away from dhcp and that auto dns manage thing
but in the end i screed up because i set netmask wrong.
they don't do fancy /30s like arp :)
so you get all these arp requests
hmm i'm seeing bootp/dhcp requests even
mercutio: do they put a whole bunch of hosts in a /24 ?
ie: different customers
some of them are /23s
but yes.
it's actually very common
If I had a supermicro server with 2 nics for connectivity, as well as one IPMI nic for power cycling / remote console connectivity, how would I setup access if I only have one ethernet cable from my provider that comes to my 2U colocation space? Would I use something like a Cisco ASA Firwall to protect the IPMI interface, while providing connectivity to the 2 regular Nics ?
something that can do transparent bridging
or just a switch would work, if you have some other way to restrict traffic to the management nic
For that matter, perhaps the BMC has its own firewall
mnathani: lots of them can run the ipmi through the primary ethernet
but ipmi's aren't really safe on the internet
the bmc's suck, and supermicro suck just as much or more than other.s
(As most embedded devices aren't, due to lack of update)
ip acl would be cool i suppose
i'm not aware of being able to do that easily
you can set vlan
but providers don't seem to usually provide vpn access to oob
arp does :)
normally i'd jkust recommend to run 2 1u servers rather than 1 2u, and be able to bounce via the other one and run them redundant/backup
