RE: Netskrt - ISP-colo CDN

[Dennis Burgess via NANOG]

They are not a CDN themselves, they partner with CDNs etc, and focusing on live 
video streams.  For FREE, you will peer with their device and they will send 
you one prefix.  That prefix will be used by CDNs if they have provisioned your 
IPs with NetSkrt.  Live streaming video will be grabbed from Amazon and 
delvered to the NetSkrt appliance once, and then all other streams within your 
netblock will be directed to that single IP on the NetSkrt device, therefore, 
you receive one stream from the internet, and the rest of the network will get 
that same stream from that box.

Again, I have several customers doing this, seeing that its FREE, all you have 
to do is give them information on the /30 that you will assign it, your BGP 
peering information and that’s about it.  Very simple.  Honestly, unless you 
have something that will deliver that transit, its really a no brainer to just 
install it and let it run.  As more services opt to use them, they will have 
more fill time as well though…

Thanks ... that svta caching sounds interesting.  i watched the presentation, 
but don't understand how it's used by ISP's that want to benefit from it.

I wonder if this is a prepackaged Open Cache box.

We also don’t appear to have had any traffic from them.  Not much on the 
peeringdb for the USA ASN either.

BGP.tools shows they have upstreams with each ASN, and are on Ohio IX with 
AS53471, but not really any peers anywhere.  Looks like Cogent and Zayo for 
upstreams and only peer I see is AS1239 (Sprint Wireline (Cogent))

Thanks... they told me it was free.

That name rang a bell so I looked up my emails.

They contacted me last year, they were claiming to be "working with some of the 
major streaming brands, such as Amazon Prime Video, to improve the quality of 
both VOD and live streaming while also reducing the load on ISP networks such 
as your own.".

Based on my quick research, they have a few registered ASNs (their peeringdb 
page) with a few netblocks but I get 0 
traffic from them (we're a sizable eyeball network). Their origin network might 
still not be ready but digging a little bit more, it seems they act as a 
third-party video caching solution and not as an origin CDN so in the end, 
they're really just trying to sell ISPs and other types of customers their 
caching solutions.

Anyone out there using Netskrt CDN?  I mean, installed in your network
for content delivery to your customers.  I understand Netskrt provides
caching for some well known online video streaming services... just
wondering if there are any network operators that have worked with
Netskrt and deployed their caching servers in your networks and what
have you thought about it?  What Internet uplink savings are you seeing?
