Comcast Predicts Usage Cap Within 5 Years

petecarlson UBB makes sense to me (475 comments)

I have to admit that I see his point. Residential bandwidth pricing is based on the concept of oversubscription. I run a small local ISP and have seen sustainable oversubscription numbers move from around 75:1 ten years ago to somewhere around 12:1 today and am using 8:1 to plan deployments for the next 2-3 years. Equipment and transit costs have come way down, which have allowed us to keep pricing relatively stable while increasing package speeds, but as we approach 1:1 usage, there is no way to make the model work without passing on full bandwidth costs, core costs, and last mile costs to the end user. Around 3% of our subs end up costing us more in bandwidth usage then they pay us for service which is supportable for now, but as that percentage grows with increased full time streaming, we will either need to raise prices across the board, or start charging based on actual usage. What would be ideal, IMHO, is 95th percentile billing, i.e 10mbps on a 100mbps circuit with 95th percentile billing above 10mbps, but the vast majority of users just wouldn't get it.

One Broken Router Takes Out Half the Internet?

petecarlson Re:I'm not sure I follow (412 comments)

If I'm understanding this 'router' thing correctly, its like a faucet connected to the series of tubes?

If not, exactly what role does this router thing play in tube interaction?

Your understanding is rather accurate but what your missing is the manifolds. You see, all the tubes connect to big manifolds with valves to control what gets sent where. At each manifold room there is some poor admin who is in charge of opening and closing valves in order to make sure that the right AOL gets sent down the right tube. In order to keep track of what tube to send your AOL down, the admin keeps a list of all the other manifold rooms and how to get to them. Some of the manifold room operators didn't have a wide enough notebook to write down the new directions so they just closed all of their valves and went home.

Perhaps they were just trying to load balance a 56k modem and a 10gb connection.

It wasn't just AS47868, it was kicked off by AS47868 sending real long routes like you can get to a by going through b, c, d, e, f ,g, h... and so on and so forth. Older versions of IOS wack out with the crazy long routes and lose their BGP sessions so it is possible that he lost half of the internet while you were on a network segment which was not seeing the issue. If the OP were to post the ASN or IP block he was on we could run BGP play and see just how much of the net he really lost. I'm going to guess about .5%.
