High Rate Internet Data Transfer for eVLBI
نویسنده
چکیده
Very Long Baseline interferometry (VLBI) is a well established technique in radio astronomy for the study of celestial sources at high angular resolution. VLBI is gradually moving to the point where Gbps data rates are becoming routine. A number of experiments have shown that the internet can be used at data rates of several hundred Mbps on production networks. However the use of switched light paths should enable higher data rates to be achieved. VLBI is resilient to packet loss, but not to loss of bandwidth. The statistics of packet loss as found by recent tests and the effects of loss on VLBI performance will be discussed. Recent measurements comparing the UKLight connection to JIVE in the Netherlands will be compared with tests on the production network.

Packet Loss in High Data Rate Internet Data Transfer for eVLBI
VLBI is gradually moving to the point where Gbps data rates are becoming routine. A number of experiments have shown that the internet can be used at data rates of several hundred Mbps on production networks. However use of the network is accompanied by packet loss. The paper discusses the statistics of packet loss as found by recent tests and investigates the expected effect of packet loss on ...

Kiwi Advanced Research and Education Network (KAREN) has been used to transfer large volumes of radio astronomical data between the Radio Astronomical Observatory at Warkworth, New Zealand and various international organizations involved in joint projects and VLBI observations. Here we report on the current status of connectivity and on the results of testing different data transfer protocols. ...
متن کاملFrom truck to optical fibre: the coming-of-age of eVLBI
Spurred by the advent of disk-based recording systems and the nearly explosive increase of internet bandwidth, eVLBI (Parsley et al. 2004) has undergone a remarkable development over the past two years. From ftp-based transfers of small amounts of astronomical data, through near real-time correlation (disk-buffered at the correlator), it has culminated this spring in the first three telescope r...

متن کاملeVLBI Development in TIGO
The Geodetic Observatory TIGO in Chile is one of the few VLBI network stations in the southern hemisphere. Concerning the growing eVLBI community TIGO, due to its remote location, has access to a very limited bandwidth of the transcontinental communication networks. Recent data transmission speed tests have been executed between TIGO and some correlator locations showing a maximum speed of 5 Mb...
