[swinog] Fun with Fiber
The Netflix guys wiring up a fully loaded ASR9010 with 118 single mode fibers: http://www.youtube.com/watch?v=tyb-nnRNwfw For those who don't know yet, Netflix is an online movie rental company and uses so much bandwidth that they had to push out their own CDN boxes to ISPs and IXPs. Their CDN boxes are almost stock FreeBSD 9.1 based, contain some 35 HDDs at 4TB plus a couple of SSDs and push about 15Gbit/s *each* during the evening hours. They are limited by HDD (seek) bandwidth. -- Andre ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

Do you think they use ZFS+L2ARC as the filesystem of their content push system? groet, Pim -- Pim van Pelt PBVP1-RIPE - http://www.ipng.nl/ ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

They don't care about disks dying, so no RAID. The availability of the content is controlled from upper layers. So if a disk dies requests for that content get redirected to another box with the same content. Only the popular movies and shows are stored on the CDN boxes. The long tail is served from AWS S3. -- Andre ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
[swinog] TSP: Agreement template for 'clip no screening' / 'special arrangement'
Yo! out there! I know this list is more about ISP than TSP, but as we mostly do both and an informal inter-TSP discussion list does not exist (or did I miss it?) I'm addessing the swinog list. We had a couple of our telephony customers asking us if we would do clip-no- screening (swisscom calls this special arrangement'). Pass on every caller-ID the customer is sending. Well, there are use cases where this can be desidered, like a PBX doing a manual transfer after answering the call, thus opening a second call leg but with the wish, that the number of the original caller is being transmitted. But! We already see a lot of abuse with invalid or fake number from other TSP with no propper outbound screening. So we would like to make our customers singn an agreement which hopefully would prevent such. Swisscom has no such template. How about the other TSP? Is there one I could use as a template for our agreement?

Re: [swinog] TSP: Agreement template for 'clip no screening' / 'special arrangement'
Hi about the list, maybe we should really create a TSP list. i would be one of the first signing up there. Roger Am 18/03/2013 11:09, schrieb Benoit Panizzon: Yo! out there!
