A Simulation Model for e-VLBI Traffic on Network Links in the Netherlands

The presenters will introduce an ns-2-based model that simulates e-VLBI traffic and the bottlenecks currently limiting the transfer speeds of astronomical data from radio telescopes across the world over high-speed Internet links to the central processing centre in the Netherlands. This model shows that a combination of large intervals between data packets, inefficient receiver hardware and excessive background traffic negatively affect the performance of e-VLBI data.
