to construct the original data. In addition, the concept of path diversity can also
be employed by multisource P2P systems. More specifically, in Apostolopoulos
[68], a multisource video communication system is proposed where the Multiple
Description Coding (MDC) is used. Multiple video servers transmit video sub-
streams to a receiver through different network paths. The concept of path
diversity is that by transmitting packets through different network paths, once
a path fails or encounters traffic congestion, the receiver can still obtain most
remaining video substreams and decode the video frames with only partial
distortion. In Nguyen and Zakhor [69], the path diversity concept is again used
