NETWORK_FAULT_TOLERANT - UDM Manager configuration option

Description

The NETWORK_FAULT_TOLERANT option sets whether or not UDM transfer sessions are network fault tolerant by default.

The Network Fault Tolerant (NFT) feature allows UDM to recover from network faults and continue processing without interruption. NFT is turned on or off with the UDM script open command.

NETWORK_FAULT_TOLERANT sets the default NFT value if it is not specified in the open command.

tip

The ACK_WINDOW configuration option controls how often UDM will stop and wait for a message to be acknowledged during a transfer. The default is for every block to be acknowledged, which may increase the total transfer time significantly in some environments. Increasing the ACK_WINDOW will decrease the total transfer time, at the cost of UDM having to retransmit more data in the event of a network fault.
