Abstract
In contrast to the first ~30 years of VLBI development, where highly specialized equipment for VLBI data-acquisition was designed and built at great cost, the last few years are being driven more and more by adapting to rapidly developing technology in the computer and networking industry. This trend is only likely to accelerate, and VLBI must position itself to take maximum advantage of these technologies. Already, the transition from magnetic tapes to magnetic disks has been very rapid, and disks will almost certainly be the mainstay of VLBI data-acquisition for the next few years. However, development of e-VLBI continues to be rapid and will accelerate. Already, international e-VLBI links of more than 500 Mbps have been demonstrated, with speeds in excess of 1-10 Gbps surely achievable in the near future. The advantages of real-time and near-real-time VLBI made possible by e-VLBI are significant, but major potential stumbling blocks are ‘last-mile ’ connectivity for many telescopes and potentially high networking costs. The future of VLBI data-acquisition and transport in the light of current and projected developments will be examined.
