Recently, Optical WDM technology is introduced into backbone networks.
On the other hand, as the future optical switching scheme, Optical Burst Switching (OBS) systems become a realistic solution. OBS systems do not consider buffering in intermediate nodes. Thus, to avoid overlapping wavelength reservation between partially interfered paths is an important issue.To solve this problem, so far, the wavelength assignment scheme which has priority management tables has been proposed. This method achieves the reduction of burst blocking probability. However, this priority management table requires huge memory space. In this paper, we propose a wavelength assignment algorithm that reduces not only the number of priority anagement tables but also burst blocking probability. To reduce priority management tables, we allocate and manage this table by each link. To reduce burst blocking probablity, our method announces information about the change of their priorities to intermediate nodes. We evaluate its performance in terms of the burst blocking probability and the reduction rate of priority management tables. |
