Time-Domain Wavelength Interleaved Networking With Wavelength Reuse
Overview Time-domain Wavelength Interleaved Networking (TWIN) is a cost-effective network architecture that can provide fine-grained, flexible connectivity using passive optics in internal nodes. Each wavelength is dedicated to carry traffic to a single node. This paper introduces TWIN with Wavelength Reuse (TWIN-WR), an extension of TWIN that allows the number of nodes to exceed the number of wavelengths. The authors formulate an associated design problem, decompose it into subproblems, and provide algorithms for solving the subproblems. The paper experimentally demonstrates that the algorithms come close to upper bounds over a wide range of parameters, and show that the resulting designs are robust in the face of traffic variability and uncertainty.
