Recently, it has a tendency to reduce an error correction and flow control in order to realize a high speed transmission in a burst transmission systems such as ATM network, IP (Internet Protocol) network, frame relay and so on. Therefore a degradation of network quality, an information loss caused by buffer overflow and decrease of average bit error rate, are occurred, especially for high speed information such as high definition television signals, it is necessary to improve these degradations.This paper proposes one of the typical reconstruction methods of lost information and an improvement of average bit error rate. In order to analyse the degradation phenomena, the Gilbert model is introduced for burst errors and the Fluid flow model for buffer overflow.This method is applied to ATM network which mainly transmit a video signals and it makes clear that proposed method is useful for high speed transmission.
