Techniques for synchronizing a clock of a first apparatus and a clock of a second apparatus in communication with the first apparatus via a network. The techniques include communicating first data between the first apparatus and second apparatus via a network, communicating, while at least a portion of the first data is being communicated via the network, a synchronization packet between the first apparatus and the second apparatus, and communicating second data between the first apparatus and the second apparatus after synchronization between the first apparatus and the second apparatus has been established.
