In response to the difficulty of satellite network management and maintenance and the urgent need for large-capacity data transmission. a software-defi ned satellite optical network cross-layer wavelength routing algorithm based on ant colony algorithm (SDNCLRWA) was proposed. The algorithm took delay and available wavelength rate as heuristic functions. and designed a two-stage cross... https://www.unitedssports.shop/product-category/winter-sports-soft-goods-baselayer/
