Accelerating Data Transfer
Through the use of tunnels, ActiveTransfer speeds up file transfers by using the server’s full bandwidth regardless of network latency or distance. For more information about this process, see Configuring and Managing Acceleration.
Use the following procedure to define a tunnel for an ActiveTransfer Server instance.
*To define a tunnel
1. In My webMethods: Administration > Integration > Managed File Transfer > Server Management.
2. Select the server instance. For details, see Selecting the Instance to Work With.
3. Click the Acceleration tab.
4. To add a new tunnel, do the following:
a. Click the button.
b. In the Tunnel Name box on the Add a Tunnel dialog box, type a name for the tunnel. The new tunnel appears in the list of tunnels.
5. Select the tunnel in the tunnel list and edit the following options in the Basic tab:
a. If you want the tunnel to start as soon as it is ready without any user intervention, select the Auto-Start check box.
b. In the Server section, the default host and port values for the destination server are 127.0.0.1 and 55580, respectively. Do not change these values.
c. In the Client section, the default host and port values for the destination server are 127.0.0.1 and 55555, respectively. Do not change these values.
d. To connect the tunnel to ActiveTransfer Server, create a tunnel back to your system, and then connect to a destination from there, select the Reverse check box.
e. In the Channels section, specify the maximum number of inbound and outbound channels to use for file transfer. These values should correspond to the appropriate multiplier for the speed gain you are looking for. Use the smallest value that still gives you the performance you need, usually 10 to 20.
6. On the Advanced tab, in the Advanced Settings section, enter the following tunnel details:
a. In the Stability Interval box, enter the number of seconds to build an average speed for a single connection. After this time is reached, channels are added.
b. In the Channel Ramp Up box, enter the number of channels to be added as the data transfer speed increases.
c. In the Minimum Fast Speed box, enter the minimum speed (in KB/s) that each channel should reach before new channels are added.
d. In the Minimum Slow Speed box, enter the speed (in KB/s) below which the channels are removed.
e. In the Speed Threshold box, enter the threshold of the speed reached (in percentage) before a new channel is added.
7. Click Save.
8. Ensure that the remaining acceleration configuration tasks described in Configuring and Managing Acceleration are completed.
