Absrrtrcr-Due to limited available photonic devices, optical networks in the near future will likely employ routing schemes that do not require sophisticated processing of optical packets. In this paper, we propose a novel self-routing scheme for all-optical packet networks that can be applied to networks with arbitrary topology. The proposed routing scheme requires only single hit processing and can he implemented with existing technologies.

Satellite communication is distinguished by global coverage and the ability to support a wide range of applications. LEO (Low Earth Orbit) satellite systems employing inter-satellite links offer rich connectivity in space and provide direct broadband access and personal communication service. One of the technical challenges for LEO systems is the design of eMicient routing strategies tailored to their highly dynamic nature. In this paper, we present a new routing method which solves the routing problem effciently by overlaying a static logical topology over the physical constellation. The algorithm generates near-optimal shortest paths. The performance of our proposed scheme is evaluated through theoretical analysis and simulations.
