Usually in the form of parallel processing with parallel multi-processor systemsare designed .For this reason irregular flow may occur with packages. When you retired and it all comes out in his NP (Network Processors) system, Reset dependingon network performance is negatively affected and we delayed To do this, Thedesign of processors working in parallel packet transmission by avoiding any packetreordering occur, If reordering, this time delay is minimal. Several algorithms havebeen proposed in recent years. In this paper, we will describe some of thefundamental concepts involved in NP architecture and algorithms packet reorderingin recent years, which causes delays are minimized packet reordering, theevaluation will be compared
