Claim Text:
1. A transmitting side terminal, comprising: a packet classifier configured to classify input service packets, used for a communication service to transmit data to a receiving side terminal over a network using a network bandwidth, as probing packets or non-probing packets, based on one or more respective features of the service packets, the probing packets being compatibly used for the communication service and probing to monitor the network without additionally consuming the network bandwidth; and a packet transmitter configured to selectively transmit the probing packets and the non-probing packets, wherein the packet classifier classifies a given input service packet of the input service packets as one of the probing packets when the given input service packet has a respective size greater than a predetermined probing size threshold, and classifies the given input service packet as a non-probing packet when the respective size is less than the predetermined probing size threshold.
