An On-Line Routing And Wavelength Assignment Algorithm For Dynamic Traffic In A Wdm Bidirectional Ring |
Abstract | ||
|---|---|---|
We develop an on-line routing and wavelength assignment (RWA) algorithm for A WDM bidirectional ring with N nodes. The algorithm dynamically supports all k-allowable traffic matrices, where k denotes an arbitrary integer vector (k(1),..., k(N)), and node i, 1 less than or equal to i less than or equal to N, can transmit at most k wavelengths and receive at most k(i) wavelengths. Our algorithm uses [Sigma(i=1)(N) k(i)/3] lengths in each ring direction to support all k-allowable traffic matrices in a, rearrangeably nonblocking fashion. Furthermore, our algorithm requires at most three light-path rearrangements per new session request regardless of the number of nodes N and the amount of traffic k. In a special case with k(i) = k for all i, 1 less than or equal to i less than or equal to N, the algorithm uses [kN/3] wavelengths in each ring direction, which is shown in [1] to be. the minimum number of wavelengths required for any off-line nonblocking RWA algorithm. |
