Why are folks turning away 10G orders? I forgot to mention a couple other issues that folks brought up: 4) the 100G equipment won't be standardized for a few years yet, so folks will continue to trunk which presents its own challenges over time. 5) the last mile infrastructure may not be able to/willing to accept the competing video traffic . There was some disagreement among the group I discussed this point with however. A few of the cable operations guys said there is BW and the biz guys don't want to 'give it away' when there is a potential to charge or block (or rather mitigate the traffic as they do now). My favorite data point was from Geoff Huston who said that the cable companies are clinging to their 1998 business model as if it were relevent in the world where peer-2-peer for distribution of large objects has already won. He believes that the sophisticated peer-2-peer is encrypting and running over ports noone will shut off, the secure shell ports that are required for VPNs. So give up, be the best dumb pipes you can be I guess. Bill On 1/10/07, Brandon Butterworth <brandon@rd.bbc.co.uk> wrote:
Then that wouldn't be enough since the other Tier 1's would need to upgrade their peering infrastructure to handle the larger peering links (n*10G), having to argue to their CFO that they need to do it so that their competitors can support the massive BW customers.
Someone will take the business so that traffic is coming regardless, they can either be that peer or be the source with the cash. If they can't do either then they're not in business, I hope they wouldn't ignore it congesting their existing peers (I know...)
Then even if the peers all upgraded the peering gear at the same time, the backbones would have to be upgraded as well to get that traffic out of the IXes and out to the eyeball networks.
The Internet doesn't scale, turn it off
