A technique for improving performance on slow links such as dialup lines. It is particularly useful when these links carry audio along with video and data. Large data or video packets can cause latency problems for any audio packets that follow them. They are reassembled at the remote end. Policy and the Admission Control Service.
Policy is a set of general rules for handling traffic.
For example, a policy might be that SAP traffic should always be given priority over other forms of traffic. Policy is stored as a schema in a policy store such as the Active Directory TM directory service. These are devices, such as routers and switches, that see the traffic flowing through them and implement the policy by allocating the resources. Policy implementation is a combination of knowing what the administrative policy is and meting out the available resources. In general, admission control determines how much traffic can be included in some class of service.
