IOS new versions and network load

Mon Sep 18 16:16:03 UTC 2017

We use a commercial product from https://qwilt.com/.  Here is some info for the month of August, while it does reduce transit the customers are also getting better speeds when it comes from us. We span links from our core to the server in order to get visibility into the server, this does cause some issues since we’ve expanded our core outside of one location.

While we don’t use Apple's caching servers we do have transparent caching in place which nets us about 82% of their content being serverd locally. On a big IOS update it will probably be close to 99% for that one title.

Would you be open to elaborating a bit on how that’s set up on your network? :)

Regards,
Marco Slater

Curious as mentioned if anyone doing this on scale? I kind of doubt it but love to hear otherwise. My assumption is this is more Enterprise focused than ISP

We've been looking into the caching server bit lately given that we're not due to get an official Apple node for at least another year yet.

It looks very difficult to manage, given the DNS TXT records and domain search fields. If it was as simple as entering the supported IP ranges, it'd be a lot easier to implement.

The caching service does support a lot more than content than "once a
year" https://support.apple.com/en-us/HT204675

Server is an app now, any MacOS can have it running.

But do carriers/ISPs really want to deal with a rack unfriendly Mac
Mini or iMac at a carrier hotel? If the Server App could run on Linux,
or if OS-X could boot on standard servers, perhaps, it it seems to be
a very bad fit in carrier/enterprise environments.

Implementation will be a little tricky, because you need your
customers to look a record in your domain.

I've tried reading some about it.
The cache server app registers with Apple its existence and the IP
address ranges it serves

When a client wants to download new IOS version, Apple checked and
finds that the client's IP is served by the caching server whose
"local" IP is a.b.c.d (akaL the inside NAT IP address). Tells client
to get version of software from that IP address.

The DNS TXT records are used by the Caching Server to get the list of
IP blocks it can serve. (not needed in the target small office
environments where everyone is on same subnet and the caching server
can tell the apple serves the one subnet it seves).
