Using the file transfer Advanced tab

When creating a new file transfer stream, or editing an existing one, use the Advanced tab of the Stream properties sheet to set the following items:

• In the Multicast Adapter Address box, select the address of the network adapter to use for broadcasting on your server. If your server has only one adapter, do not change the default selection. On computers with multiple adapters, you can use this option to broadcast separate programs simultaneously by entering a different adapter address for each program.
• In the Maximum Bandwidth box, enter the maximum amount of bandwidth to be used to broadcast the file.

  When broadcasting to clients connected to the network via modem, values in the range of from 10 kilobits per second (Kbps) through 20 Kbps are recommended.

  When broadcasting to clients on a typical Ethernet local area network (LAN), values below 1,000 Kbps are recommended.

• In the Redundancy box, set the amount of error correction to be used when broadcasting the program.

  The value that you type in the Redundancy box is rounded up to the next percentage. The setting for redundancy can range from 0.4 percent to 100 percent.

  While higher percentages of error correction help to ensure that the client receives the file correctly, they also increase the time it takes to send the file. For example, 100 percent redundancy doubles the time it takes to send a file.

• In the Duration box, type the length of time for the stream to run. Use the format hh:mm:ss, where h represents hours, m represents minutes, and s represents seconds. When the time is up, either the program ends or, if there is another stream following the current one, the next stream starts.
• In the Logging box, create a log of the file transfer broadcast. Type the path and file name for the log file in the File Path box. When the file transfer occurs, a log file containing a list of the files transferred and the destination information for each file is created.
• Click Fully Reliable to enable fully reliable file transfer.

Fully reliable file transfer allows clients to request the server to resend data that they failed to receive. After receiving a resend request, the server broadcasts the requested data to all clients. Using fully reliable file transfer can increase the network bandwidth used by the system.
