Bandwith comparison
| Submitter: | Paul Boven |
| Description: | There is a famous quote by computer scientist Andy Tanenbaum: 'Never underestimate the bandwidth of a stationwagon laden with computer tapes hurtling down the highway'. It's not a fast way to send data, but you can send quite a lot. During the past year, TIGO in Chile sent out 111 diskpacks of 2TB to Europe and the USA for correlation. That makes an average troughput of 61Mb/s. Even for remote locations like TIGO, e-VLBI is catching up: during our latest testing, we reached comparable speeds. But a diskpack takes at least a week to reach us, while data sent trough the internet is only enroute for 150ms - a huge improvement for scientists and other users, and enabling real-time correlation. |
