Scalability analysis of optical packet switch architectures

This paper addresses the major physical layer constraints of the optical packet switch (OPS) architectures. These constraints make the scaling in-efficient and this has been found that the OPS architecture can work efficiently within the bounded regimes. Analysis presented in the paper suggests that most of the already proposed architectures will not be a suitable option and multi-wavelength controlling inside the buffer is essential for the implemental optical packet switch architectures. This paper also presents an improved version of the multi-wavelength optical packet switch architecture to resolve contention among packets which further reduce the physical loss of the switch.
