Optimal Resource Allocation for Integrated Optical Path and Optical Packet Switch
Dang-Quang Bui,Hiroaki Harai,Won-Joo Hwang 한국멀티미디어학회 2010 한국멀티미디어학회 학술발표논문집 Vol.2010 No.1
Integration of optical paths and packets in a switch is one of key techniques to support ultra-highspeed traffic in New Generation Networks. However, the question on how to efficiently allocate wavelengths for optical packets and optical paths has not been solved yet because there lacks of a systematic model for evaluating performance of the integrated switch. In this paper, we model the operation of the integrated switch as a system of two queueing models: M/M/x/x for optical paths and M/M/1/LPS for optical packets. From the model, we find an optimal policy to dynamically allocate wavelength resources in an integrated switch. The simulation shows that our mechanism has better performance than other methods.

In New Generation Networks, integration of optical paths and packets in a switch is one of key techniques to support ultra-high-speed traffic. However, the wavelength allocation for optical packets and optical paths has not been efficiently resolved yet. In this paper, from modeling the operation of the integrated switch as a system of two servers, one for optical paths and the other for optical packets, we utilize Newton method to find an optimal policy for sharing of wavelength resources. Then, we propose an algorithm to dynamically allocate wavelength resources in an integrated switch. Finally, we evaluate performance of that algorithm.
