Data transport for the SKA

The Square Kilometre Array (SKA) will be the world´s largest and most sensitive radio telescope. It will address fundamental unanswered questions about our Universe including how the first stars and galaxies formed after the big bang, how dark energy is accelerating the expansion of the Universe, the role of magnetism in the cosmos, the nature of gravity, and the search for life beyond Earth. In this paper we discuss the data transport challenge posed by this transformational instrument.
