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.
