Abstract： |
The invention discloses a method for real-time measuring local service quality state of a computer network, belonging to the field of computer network measuring technique, and characterized in that: it arranges a real-time measuring module on the top of each router, where the module can generate measuring packets and is provided with a calculating formula for parameters of service quality state and a data processing method for filtering temporary fluctuation in the measuring result; as the module operates, it calculates clock difference, pack transmission delay, usable bandwidth for oriented link and packet losing ratio by periodical timer and transmission and reception of measuring packet, and adds the calculated results to a sample space and makes data processing; the module can accurately measure the latest and stable parameters of service quality state, the measuring packets are a small burden on the link and the extendibility is better. |
