Nifty, but Not Peer-To-Peer
For publishers, engineers and anyone else who needs to send very large files (100MB to 1GB-plus) over the Internet, performance and reliability can be big problems.For publishers, engineers and anyone else who needs to send very large files (100MB to 1GB-plus) over the Internet, performance and reliability can be big problems. After all, no one wants to wait a couple of hours downloading a large file and then have to start all over again if something goes wrong two-thirds of the way through. An answer to this problem, (although not "the" answer) is Gigabyte Express 5 from Niwot Networks. Although Niwot pitches it as a peer-to-peer product, the $795 Gigabyte Express is more accurately a point-to-point product, letting a business connect to clients over the Internet for managing large file downloads. The client can use standard TCP/IP, but it also uses an extension to TCP/IP for increased download reliability.
In tests, Gigabyte Express did a good job of seamlessly recovering from interrupted packets. Performance improvements (or lack thereof) may vary based on the situation. On a standard Internet connection between clients in Colorado and Massachusetts, Gigabyte Express was actually slower than an FTP connection. However, I got improved speed on a cable modem, and Niwot positions the product to businesses with international clients.
