Conventional search techniques for extrasolar planets have not yielded indisputable evidence of such planets. The small sample sizes of previously employed searches ensure that a null result provides little or no information on the numbers or distributions of such planets. The photometric technique, wherein monitoring is performed to detect light curves distinctively characteristic of a planetary transit, has been a tantalizing prospect, but has always been rejected because of its observational intensity. Moderate aperture (0.5-1.0 m) automated telescopes and multi- color CCD imaging arrays with image recognition software form the instrumental foundation for a global network to conduct such a search. Catalogs of cool dwarf stars provide a program star list with the advantages of orbital geometries and photometric properties enabling detection of planetary transits with a network of modes proportions. We reaffirm the viability of the photometric approach and outline the methodology of the search. Computer modelling of various strategies of conducting such a planetary search has been undertaken and we outline the resulting network configurations and observing strategies suggested by this effort.
