Abstract

We propose an optical network and an algorithm for it to distribute a token (shared resource) mutually exclusively among a set of n processing elements (nodes). The token is granted in constant amortized time following a request, assuming constant propagation time for light within the environment. Additionally, the distribution of tokens is fair, ensuring that no token request is denied more than \(n-1\) times in succession. The proposed algorithm is distributed (nodes operate without centralized control) and asynchronous (does not use a common clock).
