Actually, it sounds a lot like the Electric7 tariffs found in the UK for electricity. These are typically used by low income people who have less education than the average population. And yet they can understand the concept of saving money by using more electricity at night.
I can't comment on MPLS or DSCP bits but the concept of night-time on the internet I found interesting. This would be a localized event as night moved around the earth. If the scheduling feature in many of the fileshare applications were preset to run full bore during late night hours and back off to 1/4 speed during the day I wonder how that might affect both the networks and the ISPs. Since the far side of the planet would be on the opposite schedule from each other, that might also help to localize the traffic from fileshare networks. Seems to me a programmer setting a default schedule in an application is far simpler than many of the other suggestions I've seen for solving this problem. Geo. George Roettger Netlink Services
