Content providers (e.g. Netflix, Hulu, YouTube) will always try to get their
content serviced for little to no cost. The low cost, web-only plan isn't
sustainable, and the amount of Netflix traffic around the globe is a good
example; There's a lot of traffic that they aren't paying for. The fre

It's essentially a 2 token bucket system. We implement based on the rate plan
given via our DHCP server for residential customers, but it can be implemented
using QoS on any router. Most DHCP server platforms offer it, and it is written

Interestingly enough, we've tried to do H.323 with some folks on a CMTS
connection, and have yet to succeed in smooth video. M
So, we seem to circle the same points:
1. Who pays for the infrastructure to support the increased bandwidth
requirements?
Comcast and most ISPs want the content provider to do so, since they
are collecting fees for the service and they are not, but still have to pay for
the bandwidth
Interesting point. I'd also like to point out that putting the cost on the
content providers rather than the network may raise the cost of the content
service, but only to those that want that service. In effect, if the transport
provider is paying for the bandwidth generated by a content provid
This should also be a wake-up call that for whatever reason (who cares what for
this discussion), if our bandwidth demands exceed our bandwidth supply, we must
become more efficient at using our bandwidth. I'm hoping that we not only
discuss peering and bandwidth, management and implementation,
I'm surprised that no one seems to think that "bandwidth" is really just a
series of interconnects. If indeed their links are saturated, they are probably
either near an upgrade point (if their forecasting was correct) or trying to
negotiate one (if their forecasting is bad or there is a sudden
I don't see anything listed that indicates operation that is at all different
from any other service provider network.
The "capacity" issue listed is not an issue at all. It's simply inciting anger
and the same rhetoric that pollutes the legitimate discussion of backbone
network constraints.

I just wanted to stop and say I'm glad we can have this kind of debate :)
I think we need to start with education at every level. Watching 1-2 movies a
day, some additional streaming content, using the VoIP phone whenever, and
surfing the web is normal behavior. Running occasional P2P is normal

Essentially, the question is who has to pay for the infrastructure to support
the bandwidth requirements of all of these new and booming streaming ventures.
I can understand both the side taken by Comcast, and the side of the content
provider, but I don't think it's as simple as the slogans spew
Do you have the VPN/SSL AIM module? That would offload the crypto work.

have to rely on someone else.

What exact commands did you add to get the MPLSoGRE working ? If you
remove them do the web traffic issues stop ? Is the traffic narrowed to
being dropped by the 7600 ?
