What are we doing?
We used to have an allowance of 10GB a week data transfer per ResNet user. We are changing this so that in future we will have no overall limit for the whole week, but limits for the busiest time of day only. The day is divided into peak and off-peak periods:
- Off-peak period (12 midnight-6pm): no limit
- On-peak period (6pm-12 midnight): allowance of 2.5GB a person a week
Why are we doing this?
We have had a ResNet fair usage policy for a while. It tries to make sure that our pipe to the Internet is available fairly to all and not used up by a few.
The evening is the busiest time for ResNet. It is only during the busiest period that our pipe to the Internet can get full and performance suffers. We’d like to reduce usage during this time so the network still works well for everyone on it.
If we have spare capacity during the rest of the day there is no reason that people shouldn’t use it then. Some things, like backups or large downloads, you can do at any time.
We are trying as far as we can to provide a service that suits everyone, or at least balances conflicting demands. For example, heavy users can schedule large downloads to take place off-peak without any penalty. As there is no off-peak limit then over a week heavy users will actually be able to do more than they could before. Reducing large transfers during the evening means that sensitive real-time usage (such as webcams, telephony or games) will work better during the busy period.
When does it start?
Monday 23rd April 2007 (start of summer term)
What happens if I use more than the allowance?
The morning after you exceed your weekly on-peak allowance your ResNet connection will be automatically moved into a different network segment and will stay there for the rest of the week. This network area is shared with other heavy users. Your connection may be much slower. You will still be able to get at websites, email, and internal University resources like Blackboard, but other things such as Skype, webcams or Internet radio will stop working.
How do I know how much I’m using?
See Manage My ResNet to view your usage.
Please first see the fair usage policy for more information and then email us if there is more you need to know.
