One-way Loss Pattern Sample Metrics

Using the base metric defined in RFC 2680, this document defines two derived metrics loss distance and loss period, and the associated statistics that together capture patterns experienced by packet streams on the Internet. The Internet exhibits certain specific types of behavior (e.g., bursty packet loss) that can affect the performance seen by the users as well as the operators. The pattern or distribution is a key parameter that determines the performance observed by the users for certain real-time applications such as packet voice and video. For the same rate, two different distributions could potentially produce widely different perceptions of performance.
