Abstract: A novel burst assembly algorithm with safety space is proposed for optical burst switching in edge routers.Moreover, a concept of unit input bit rate is introduced to improve universality.Based on this algorithm and self-similar traffic, the assembly process is simulated.Influences on burst creation, burst length distribution, packet loss ratio, total output data, and valid information ratio are discussed by setting appropriate parameter values including ultimate burst lengths, assembly time threshold, etc.

Key words: assembly algorithm, self-similar traffic, wavelength division multiplexing, optical burst switching
