Traffic Shaping on ISPs

Thu Sep 10 08:50:53 UTC 2009

Hi Jake

While I cannot confirm officially, there is a lot of rumors, that several
larger UK ISP's are throttling traffic at that time period.
I am not sure who to contact, but the individual ISP's to solve this, from
your point, maybe another NANOG'er knows.

Subject: Traffic Shaping on ISPs

Hi Nanog, 

We have recently introduced a MMORPG (online game) to the Internet. We
currently are receiving many complaints from UK (and a few EU) customers of
sudden traffic loss or slowness which makes the game unplayable. The
complaints come through like clockwork from 6:00PM to 11:59PM (GMT). Our
chief complaint customers originate from British Telecom who equate to an
aggregate estimate of 200Mbps during said hours. 

Is there any advice, known traffic shaping bucket or predictive traffic
shaping of sorts that could be impeding our customers use over our ports
TCP/7000-7500? Would our traffic be considered P2P traffic and throttled
once inside their ASN (or even outside)? 

Understandably ISPs would want to protect the precious bandwidth and IP
services.

We are based in US but I am at a wits end on route shifting over our major
ISP connections and finding no resolution. 

Is there anyone who has experienced cross-the-pond issues such as this and
had had luck in finding a resolution or at least an answer? (Maybe a form to
fill out for cut-through allowance/whitelist for our prefix and port range,
if such a thing existed?).

Much obliged, 
Jake
