摘要：
A method for migrating data transmitted from a transmitter to a receiver over a first stream to a second stream in a reliable multicast system is provided. The method comprises transmitting a first message from the transmitter to the receiver over the first stream to notify the receiver that a first data flow transmitted on the first stream will be transmitted on the second stream. The transmitter transmits a second message to the receiver over the second stream after a second threshold has expired. The receiver tunes to the second stream based on the second message. The transmitter transmits a third message to the receiver over the first stream after a third threshold has expired to notify the receiver that transmission of the first data flow over the first stream will be terminated. The transmitter then transmits a fourth message from the transmitter to the receiver over the second stream after a fourth threshold has expired.
