3.5. TCP service Configuration
If a TCP session is established between two hosts, the connection should be closed (normally or
abnormally) by either of the hosts to prevent the lock-up of the corresponding TCP port. To prevent
this type of lock-up situation, the Parani-MSP1000 provides a TCP “keep-alive” feature. The Parani-
MSP1000 will send packets back and forth through the network periodically to confirm that the network
exists. The corresponding TCP session is closed automatically if there’s no response from the remote
host.
