Abstract
A system and method for policing of access to resources in a heterogeneous data redirection device is disclosed. The invention utilizes Random Early Detection to determine whether or not a given packet should be dropped or accepted into the resource. The invention uses a combination of different metrics each of which utilizes a different version of RED. Schemes can include a Per-Flow Weighted RED metric, a Global RED metric and a Fair Share Pool metric, where shared resource allocation is dependent dynamically upon the number of users at the time a packet requests access. These metrics can be combined in variety of ways to yield a final drop or accept decision for an incoming packet so that it does not access resources.
