✦ Synopsis
A simple solution for the wavelength-routing assignment problem has been presented. This solution relies on a basic algorithm, and the first aim of the solution is either to propose a minimum delay path or, as far as possible, to minimize the number of wavelengths in the network. The solution also relies on the use of a simple and widely available platform, such as Maple, with predefined graph libraries.
A criticism that software experts may pose is that Maple is an inconveniently hea¨y platform for dealing with WRA problems. They might also object that a better job would be done with dedicated software.
Although, strictly speaking, the above is true, the present solution reaches satisfactory practical results, with minimal effort, time, and cost.
The discussion may then become one of choosing to give Ž . importance to pragmatism the present solution or time-con-Ž suming software purism which means implementing a dedi-. cated software .
Concluding, the literature presents some other solutions for the WRA problem using sophisticated and expensive pieces of software, sometimes running with workstations and supercomputers. These tools are only affordable for wealthy research groups. The very simple solution presented in this paper may easily deal with networks up to 13᎐15 nodes in a very economical way. It is also able to deal with 80᎐90% of the situations that occur in actual practice, using widely available tools. Although this paper does not add to the present state of the art of WRA itself, it offers a much-needed contribution to the WRA field, which until now has been very costly. It opens up a pragmatic possibility for modest groups to work and endeavor to compete in the WRA field.
