Gather evidence, attempt to work cooperatively, then name and shame if necessary. But yes, that's close to my intention. If you do your homework properly, the greater networking community is very powerful and will back you. Those companies are largely ones that will work with you. Forget Amazon, Sony, etc. though.
I've heard from people seeing this with Microsoft, Akamai, Limelight and Apple. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "That One Guy /sarcasm" <[email protected]> To: [email protected] Sent: Monday, September 19, 2016 10:16:26 PM Subject: Re: [AFMUG] CDN Overload Did you just indicate an intention to get a cdn to alter a corporate policy?

What have you identified the traffic to be? What is the access network? Where is the rate limiting done? How is the rate limiting done (policing vs. queueing, SFQ, PFIFO, etc,, etc.)? What is doing the rate limiting? What is the rate-limit set to? Upstream of the rate-limiter, what are you seeing for inbound traffic? One connection or many? How much traffic? How does other traffic behave when exceeding the rate limit? Where is NAT performed? What is doing NAT? Shared NAT or isolated to that customer? Have you done a packet capture before and after the rate limiter? The NAT device? Would you be willing to send a filtered packet capture (only the frames that relate to this CDN) to the CDN if they want it? There have been reports of CDNs sending more traffic than the customer can handle and ignores TCP convention to slow down. Trying to investigate this thoroughly so we can get the CDN to fix their system. Multiple CDNs have been shown to do this. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP
