1. A method of transmitting packets over a network, comprising:

  • receiving a bandwidth requirement for transmitting packets over a network;

    from a first network endpoint, transmitting a first plurality of test packets over a single network path of the network to a second network endpoint during a first plurality of time locations that are spaced apart in time, wherein a transmission rate of the first plurality of test packets is determined based on the received bandwidth requirement;

    based on an evaluation of the first plurality of test packets, determining which of the first plurality of time locations corresponds to favorable network traffic conditions over the single network path; and

    scheduling data packets for transmission over the single network path of the network during one or more of the time locations corresponding favorable network traffic conditions, wherein the data packets are synchronized to a time reference frame at the first network endpoint.
