Abstract: A communication apparatus can perform reliable and stable communication with one or more counterpart apparatuses in a communication network, where the network has plural communication paths in which data communication transmissions are performed according to a predetermined transmission condition. The transmission condition of a communication packet for at least one of the plural communication paths is determined to be different from the predetermined transmission condition if bandwidth measurement is not performed on that communication path while bandwidth measurement is performed on one or more of the other communication paths. Accuracy of measuring available bandwidth in the communication network can be improved because communication paths that perform bandwidth measurements are less impacted by communication paths that do not perform bandwidth measurement.
