Transfer Parameters in FileCatalyst Express
FileCatalyst Express (and the two way java applet) now have the ability to set transfer parameters for transfer speeds up to 10 Gbps. Transfers up to 500 Mbps were always possible with Express using the out-of-the-box settings. For faster speeds however (>1 Gbps on high latency networks), users normally required tuning a few parameters in order to get full speeds out of our client software. These parameters are now exposed in the Express and two way applet as of v3.1 build 23.

Feature of the Month
Congestion Control Algorithms
Being a UDP transport protocol, FileCatalyst cannot rely on lower level protocols (TCP) to see if we've saturated the line to its maximum potential, or for slow downs due to other traffic being detected on the same link. The portion of FileCatalyst software responsible for this is called "congestion control".
There are two strategies we employ for congestion control: loss based or RTT based.
The default (as of v3.1) is our packet loss algorithm, which uses a combination of network statistics to determine if the line speed is over saturated, including decaying latency values and line packet-loss. This is a very fast responding algorithm which is the best solution for terrestrial transfers with limited packet loss.
The RTT based algorithm works extremely well in high loss transfer environments. Not being bound to packet loss as an indicator for network congestion (wi-fi/cellular transfers, some overseas links), the protocol can overcome links which would normally bring other protocol to their knees.
But for some links, having the option of NO congestion control is very desirable. Dedicated satellite links (where periodic high packet loss compounded by high latencies), removing congestion control and simply sending data at line speed will produce the fastest transfer rate.
Tips and Tricks
HotFolder: Run at Login on Mac OS X
For any clients that are running HotFolders on Mac OS X that use scheduled upload times for regular data transfer, it may be best to have them enable the "run at login" feature.
To enable this feature have them perform the following:
- Under "System Preferences", select "Users & Groups"
- Select the user and select "Login Items"
- "Unlock" to make changes (enter password when requested)
- Select "+" to add program
- Browse to "FileCatalystHotFolder.app" and select it
- Select "Hide" to have the application launch with no GUI but with scheduled transfers still enabled.
Note: the application is not being set up as a system service; it will be launched only when the specified user logs in.

Pride in our Work. Confidence in our Performance.
Last year, the FileCatalyst team was approached with an interesting proposition. A PhD researcher from the Anhalt University, wished to test multiple transfer solutions from competing vendors as part of his work.

FileCatalyst Central v3.2: Flexible Views
With the upcoming release of FileCatalyst Central 3.2, the team managed to find a bit of time to sneak in the "flexible views" feature. While hovering over the blank space in the title bar of any panel (on desktop computers), you will see the "crosshairs" cursor appear..
