Implementations
Leaky bucket
A leaky bucket is a buffer used to store incoming/outgoing traffic. It then leaks out packets at a set rate slowing down incoming or outgoing traffic to a desired rate.
Token Bucket A Token bucket is like a leaky bucket except that is uses tokens which are added to the bucket at a set rate. The Speed at which it lets traffic pass through the bucket is determined by the number of tokens currently in the bucket. Tokens are rmoved from the bucket as traffic is allowed to pass through.
Costs and Benefits
Use's
ISP's Internet Service providers will use traffic shaping increase performance of traffic that depends on good delivery times. This includes VoIP and gaming. Doing this by slowing down traffic that does not depend on latency. An example of this would be Torrents. Often users have torrents running in the background so having there traffic slowed down causes little inconvenience.
