Usage Guidelines

Usage Scenario

An HSB service sends and retransmits HSB packets to prevent long TCP interruption that is not detected by the protocol stack. If a device does not receive an HSB packet from the peer device within the period (value of retransmit-times x value of interval-value), the local device receives a message indicating the exception and then re-establishes a channel to the peer.

Prerequisites

An HSB service has been configured.

Example

# Set the retransmission times of HSB service 0 to 5, and the retransmission interval to 1 second.
