Queueing analysis of optical hybrid switching

In this paper, we present a simple analytical model of optical hybrid switching which combines Optical Burst Switching (OBS) and Optical Circuit Switching (OCS). For queueing analysis, the burst generation process is assumed to follow a two-state Markov Modulated Poisson Process (MMPP), and the service rate fluctuates based on the number of concurrent OCS sessions. This paper has provided an analytical tool for provisioning capacity in an optical hybrid system to increase network utilization subject to meeting QoS requirements.
