RocketStream Station 的免费替代品？
我刚刚尝试使用 RocketStream Station (www.rocketstream.com) 作为 FTP 的替代方案，用于长距离 Internet 传输大文件（延迟相对较高），并且它的性能令我震惊，对我来说，它的速度是 FTP 速度的 125 倍以上。它使用 Udp 作为数据通道或他们称为“Pdp”的协议。
此应用程序有免费（或更便宜）的替代品吗？
I just tried RocketStream Station (www.rocketstream.com) as an alternative to FTP for transferring large files over long Internet distances (relatively high latency) and was blown away by its performance which for me was over 125 times the speed of FTP. It uses Udp for the data channel or a protocol they call "Pdp".
Are there any free (or cheaper) alternatives to this application?

Kurt，
我们使用 Data Expedition, Inc. 公司的产品。他们的 ExpeDat 软件是一款高速文件传输产品，非常适合我们（我们的平均文件大小为 4GB，在加利福尼亚和欧洲之间的线路为 45Mbps）。它们也是基于 UDP 的，大约 18 个月前，当我们做出决定时，我们将它们与几个供应商进行了比较。 Rocketstream 是 Data Expedition 为我们的情况击败的供应商之一。
希望这有帮助！
Kurt,
We use a product from a company called Data Expedition, Inc. Their ExpeDat software is a high-speed file transfer product that works very well for us (our avg. file size 4GB, 45Mbps lines, between California and Europe). They are also UDP-based and we compared them to a couple of vendors, roughly 18 months ago, when we were making our decision. Rocketstream was one of the vendors Data Expedition beat out for our situation.
Hope this helps!
我还必须回应 Jim 上面关于 ExpeDat 和 Data Expedition 的声明。我们的特定场景涉及纽约和英国之间的 100 兆连接，每天移动 10 GB。由于某种原因，我们测试的大多数基于 UDP 的应用程序都很难扩展，并且只能为我们提供约 50-60% 的吞吐量，而 ExpeDat 始终为我们提供 90% 以上的吞吐量。
除了技术之外，这些人真的很容易合作（没有支持或定价等方面的废话），我们很高兴找到他们，绝对是一家规模较小的公司，但我们已经向客户推荐过他们。 www.dataexpedition.com 是那里的网站。祝大家好运！
I have to also echo Jim's statement above re: ExpeDat and Data Expedition. Our particular scenario involves 100 meg connections between NY and the UK with 10's of GBs being moved daily. For some reason most of the UDP-based applications we tested had a hard time scaling and were only getting us ~50-60% throughput while ExpeDat consistently gets us 90+.
Technology aside, these guys have been really easy to work with (no BS on support or pricing, etc.) and we're pretty glad we found them, definitely a smaller company but one which we've recommended up and down to our clients. www.dataexpedition.com is there site. Good luck all!
