Overview of Bucket VTA Example

In this example each subscriber has a bucket account; that is, an account that is periodically measured and refilled depending on the usage of the account.

In this example, there are two bucket sizes:

• Behaving bucket size—2 GB
• Misbehaving bucket size—1 GB

The rate at which the buckets are refilled depends on usage. If the subscriber is staying within the behaving rate, the bucket account is refilled at the rate of 2 GB per week. If the subscriber is exceeding the behaving rate, the bucket account is refilled at the rate of 1 GB per week:

• Behaving refill rate—3550 bps, or 2 GBs per 7 days
• Misbehaving refill rate —1775 bps, or 1 GB per 7 days
