Abstract :
This letter considers an Internet streaming protocol (SP) for the transport of real time continuous data stream. SP makes use of measured network delay to optimally set retransmission time-outs and scale reliability. The sender streams out packets in a periodic manner, and a NACK is issued by the receiver if it does not receive an expected packet by a certain time. Although it may appear at first glance that the sender´s and receiver´s clocks must be synchronized, we prove that that the SP would work even if the clocks were not synchronized, a situation not uncommon in the Internet.
