From PANDORA Network to PANDORA Switch

摘要

PANDORA is a network architecture that uses a static scheduling of predetermined data transfer patterns to exploit the reduction of the data transfer delay on optical communication channels. Static scheduling of data transfers removes or hides the other overheads, such as routing and buffer control, which often are a major bottleneck in current interconnection networks. Earlier we proposed an optical implementation of PANDORA based on the use of Wavelength Division Multiplexing to achieve bit-parallel data transfer on a single waveguide. In this paper, we describe a further refinement in the PANDORA network architecture to achieve sub 100 ns data transfer delays.
