<p>PROBLEM TO BE SOLVED: To provide methods and apparatus for determining the quality of a communication link transmitting a specified packet type.SOLUTION: A method includes configuring first packets, which share transmission characteristics with a specific packet type, such as a voice over IP packet, such that the first packets experience similar communication link treatment to the specific packet type. The first packets are then transmitted to a quality monitoring server located near termination equipment of the particular communication link. Second packets, which are transmitted by the server in response to the first packets, are received and evaluated to determine the quality of the communication link based on characteristics of the second packets.</p> |
