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 (k1,..., kN), and node i, 1 i N, can
transmit at most ki wavelengths and receive at most ki wavelengths. Our algorithm uses
