5. The most important parameter to set is the VFS Gateway Address. Enter the
IP address of the Vipersat modem (e.g., CDM-570L) on the local network
that serves as the gateway to the VMS for this PC/workstation.
6. Set the default parameter values for Session Configuration:
Source Root Path – Directory path location on local transmitting host from
which files will be transferred.
Destination Root Path – Directory path location on remote receiving host to
which files will be transferred. This must be a valid/existing path.
Ideal Bit Rate – Maximum bit rate for file transfer. Ideally, this value will
match the Application Policy maximum bit rate.
Minimum Bit Rate – Minimum bit rate for file transfer.
7. Set the default parameter values for Global Configuration:
Retry Count – Number of retries allowed to complete any single VFS
transaction (e.g., session set-up, VESP, dropped packet retransmission).
Time Out – Amount of time allowed to attempt to complete any single VFS
transaction before ending that attempt. This time must accomodate any
delays and/or latencies expected in the network.
The check box Options are defined as follows:
Archive – Once the specified file/folder has been successfully transferred,
it is removed from its source directory and placed into the VFS Archive
folder that is created in that same directory. Once the file/folder has been
archived, it is no longer available for subsequent transfers from the source
directory.
Overwrite – For periodically scheduled transfers, the received file
overwrites the previous copy of that file in the destination directory.
Share – Allows shared access to the source and destination file during file
transfer.
Blocking – Prevents concurrent file transfer sessions. This is an option for
Hub gateway modems to prevent exceeding the bandwidth on the TDM
outbound carrier.
Aggregate Bit Rate – The maximum sum of the bit rates for all concurrent
VFS sessions allowed over the TDM outbound channel from the Hub. This
parameter must be set to a value that is less than the available bandwidth of
the TDM outbound.
Excess Bandwidth – Percentage of additional bandwidth required to
accommodate any overhead transmitted from a Remote.
