General

This module includes functions for all Thread roles.

Summary

The Network Data Publisher provides mechanisms to limit the number of similar Service and/or Prefix (on-mesh prefix or external route) entries in the Thread Network Data by monitoring the Network Data and managing if or when to add or remove entries.

All the functions in this module require OPENTHREAD_CONFIG_NETDATA_PUBLISHER_ENABLE to be enabled.

Note: The functions in this module require OPENTHREAD_FTD=1 or OPENTHREAD_MTD=1.

This function requires the feature OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE to be enabled.

Only stable entries can be published (i.e.,aConfig.mStable MUST be TRUE).

A subsequent call to this method will replace a previous request for the same prefix. In particular, if the new call only changes the flags (e.g., preference level) and the prefix is already added in the Network Data, the change to flags is immediately reflected in the Network Data. This ensures that existing entries in the Network Data are not abruptly removed. Note that a change in the preference level can potentially later cause the entry to be removed from the Network Data after determining there are other nodes that are publishing the same prefix with the same or higher preference.

Details
Parameters	[in] aInstance A pointer to an OpenThread instance. [in] aConfig The external route config to publish (MUST NOT be NULL).
Return Values	OT_ERROR_NONE The external route is published successfully. OT_ERROR_INVALID_ARGS The aConfig is not valid (bad prefix, invalid flag combinations, or not stable).

This function requests an on-mesh prefix to be published in the Thread Network Data.

This function requires the feature OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE to be enabled.

Only stable entries can be published (i.e.,aConfig.mStable MUST be TRUE).

A subsequent call to this method will replace a previous request for the same prefix. In particular, if the new call only changes the flags (e.g., preference level) and the prefix is already added in the Network Data, the change to flags is immediately reflected in the Network Data. This ensures that existing entries in the Network Data are not abruptly removed. Note that a change in the preference level can potentially later cause the entry to be removed from the Network Data after determining there are other nodes that are publishing the same prefix with the same or higher preference.

Details
Parameters	[in] aInstance A pointer to an OpenThread instance. [in] aConfig The on-mesh prefix config to publish (MUST NOT be NULL).
