Generalized error control techniques for integrated service packet networks

This paper presents some generalized error control techniques that allows one to fulfill the delay and reliability demands of applications over integrated service packet networks (ISPNs). Binary frequency shift keying (FSK) modulation, which is suitable for lightwave packet networks and which, in addition, allows noncoherent detection in place of the classical coherent detection, has been considered. Performance is derived in terms of region-by-region and end-to-end error control. The proposed protocols performed better than previously described techniques, especially under poor channel conditions. In addition, the use of noncoherent detection produced a considerable reduction in receiver implementation complexity
