Re: Global caches
When I did post the following, I did not, as it turns out, have good documentation of how TLMC actually works. I do hope that what I've done during these days, can describe TLMC better than the current website can. So there is a file called 'document packages' on the site right now. (tlmc-20130207-r1.tar.gz) The file 'TLMC.OVERVIEW' should, hopefully, get you an better idea of how TLMC works. The complete DNS server for both the CSP and the ISP is included as well as the plug-in for the Traffic Server (which is required to let end user/customer to cache the content at their home). Does anybody know of any other CDN providers that offer similar caches? Yes. The Last Mile Cache. http://tlmc.fredan.se It's an completely open solution for everybody, both the ISP (Internet Service Provider) and CSP (Content Service Provider). -- //fredan

Most CDN providers also provide free access to super node caches at major datacentres and peering points - depending on where you are located, which datacentres you're in, and what your network looks like, you may find that it's cheaper for you to interconnect with the CDNs within a datacentre (particularly if you can do it via an IX), than the provide space and power for CDN nodes within your own network.

Re: Global caches
While I would agree with that, having peering helps but certainly doesn't replace a localized CDN. Certainly better than nothing though. It also of course depends on the size of your network. If you are paying to carry that traffic (leased backhaul, etc.) from your peering point to your customers, you are still paying the same amount to deliver that content to your users (excluding any transit savings if moving from transit to get that CDN content). That is where an on-net CDN really saves you significantly as you can bury it deep into your network. I can't speak specifics here but I can tell you that the CDNs we have are filled at off-peak, so it really does become a win-win from a technical perspective (business case and politics are a completely different conversation though). -Jeff On Feb 4, 2013, at 6:50 AM, Simon Lockhart si...@slimey.org wrote: On Mon Feb 04, 2013 at 02:03:54PM +, Kyle Camilleri wrote: Does anybody know of any other CDN providers that offer similar caches?

RE: Global caches
Hi Alex, We already have Google Cache although we don't peer with them directly. As said earlier, what I'm after is to cache content to provide better performance to our customers and alleviating some bandwidth towards provider. Taking an example of Global Google Cache, they provide and manage the servers themselves, absolutely no huge effort needed from the ISP. Making it very convenient. I know of Akamai and Netfix that does this in a fairly similar way, but would like to know if there are any other CDNs that do this.

Does anybody know of any other CDN providers that offer similar caches? I think I should give a note of caution first. Normally, CDNs will only consider you for caching if you already peer with them - in most cases the majority of any performance or cost improvements come from direct peering with a CDN first. Unfortunately, I can't find an entry for you on PeeringDB, but assuming that you are AS12709, you only seem to be peering with a few 'major' networks (Vodafone Malta (AS33874) WIND Italy (AS1267), Global Crossing (AS3549) and Level3 (AS3356)). If you don't (or can't) peer with, say, Google or Akamai, they are unlikely to invite you to join their caching systems. I'm guessing that because you are on an Island in the middle of the Mediterranean; with nobody wanting to peer on the Island, you are looking to cache as much as possible on the Island, as undersea cables are expensive. Is this correct? If you give the list a bit more information about what the problem you are trying to solve is, the people here are pretty good at coming up with solutions or putting you in contact with people who may be able to help. Best wishes, Alex
