This is the function to receive the lost packet by sending a resend request to the ITCH server for recovery if the loss of a UDP multicast packet or participant system failure are detected.
The ITCH user can receive the lost packet by sending a resend request to the ITCH server when the loss of a UDP multicast packet are detected.
Since Rewind is used for recovery in the event of information loss or participant system failure, in principle, it should not be used for other purposes.
