| Research Abstract |
Our final objective indicates realizing improvement in packet loss performance, in the next-generation optical packet switching network, taking device restrictions of an optical buffer, light wavelength conversion, etc. into consideration. In this study, first of all, we established tightly-cooperated control method between wavelength converters and optical buffers which improves the loss performance of an optical packet switch. Next, the connection-level prioritized wavelength assignment method suitable for an optical packet switching network was established. Finally, the determination method of the priority wavelength set (priority wavelength bundle) to assign to each route on entire network was established.
