METHOD FOR NON-COOPERATIVE MEASUREMENT OF NETWORK DATA-PATH QUALITY
First Claim
1. A method for non-cooperatively measuring data-path quality of a communications network, comprising:
- (a) sending from a measuring node a probe designed to elicit a response from a remote node, said probe comprising at least two data packets with a content being application messages, and said response from said remote node containing at least one data packet which contains at least one application message or a portion of an application message;
(b) receiving and processing said data packet in said response which are capable of providing at least three types of data-path quality metrics; and
(c) obtaining a measurement or assessment about data-path quality between said measuring node and said remote node from said data-path quality processed in step (b).

Abstract
A method and apparatus for measuring network path quality in a non-cooperative manner, which involves sending a probe consisting of a plurality of probe data packets to a remote node and receiving a response consisting of at least one response data packet therefrom. Both the probe and response data packets carry application messages and are exchanged according to normal transmission mechanisms, so that the method can void the reliability problem suffered by methods using non-data probes. The response data packets, at the same time, provide sufficient information for obtaining a rich set of data-path quality metrics in an efficient way.
