Abstract

This paper studies the problem of the implementation of distributed computing applications in local area networks. We propose a novel Dynamical Wavelength Scheduled Wavelength Division Multiplexing Passive Optical Network (WDMPON) architecture, in which the number of the available upstream wavelength channels is greatly less than that of optical network units (ONU). And we experimentally demonstrate the feasibility of the proposed WDM-PON, which enables dynamically scheduling upstream data in the time division multiplexing (TDM) and WDM scheme from ONU to optical line terminal (OLT). The Time-Wavelength Co-Allocation (TWCA) Problem is defined in the proposed WDMPON architecture to aggregate large files for distributed computing applications and three scheduling algorithms are presented to solve this problem. The significant improvement compared with the conventional TDM-over-WDM PON is illustrated through simulations.
