Providing a photonic alternative to the current electronic switching in the backbone, optical packet switching (OPS) and optical burst switching (OBS) require optical buffering. Optical buffering exploits delays in long optical fibres; an optical buffer is implemented by routing packets through a set of fibre delay lines (FDLs). Previous studies pointed out that, in comparison with electronic buffers, optical buffering suffers from an additional performance degradation. This contribution builds on this observation by studying optical buffer performance under more general traffic assumptions. Features of the optical buffer model under consideration include a Markovian arrival process, general burst sizes and a finite set of fibre delay lines of arbitrary length. Our algorithmic approach yields important performance measures such as the packet loss rate and the mean delay with a reasonable amount of computational time.
