General#

This module includes functions for all Thread roles.

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.

A call to this function will remove and replace any previous "DNS/SRP Service" entry that was being published (from earlier call to any of otNetDataPublishDnsSrpService{Type}() functions).

Publishes the "DNS/SRP Service Unicast Address" by including the address and port info in the Service TLV data.


Definition at line 127 of file include/openthread/netdata_publisher.h

otNetDataPublishDnsSrpServiceUnicastMeshLocalEid#

void otNetDataPublishDnsSrpServiceUnicastMeshLocalEid (otInstance * aInstance, uint16_t aPort)

Requests "DNS/SRP Service Unicast Address" to be published in the Thread Network Data.

Parameters
[in]aInstance

A pointer to an OpenThread instance.

[in]aPort

The SRP server port number to publish.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

A call to this function will remove and replace any previous "DNS/SRP Service" entry that was being published (from earlier call to any of otNetDataPublishDnsSrpService{Type}() functions).

Unlike otNetDataPublishDnsSrpServiceUnicast() which requires the published address to be given and includes the info in the Service TLV data, this function uses the device's mesh-local EID and includes the info in the Server TLV data.


Definition at line 145 of file include/openthread/netdata_publisher.h

otNetDataIsDnsSrpServiceAdded#

bool otNetDataIsDnsSrpServiceAdded (otInstance * aInstance)

Parameters
[in]aInstance

A pointer to an OpenThread instance.

[in]aCallback

The callback function pointer (can be NULL if not needed).

[in]aContext

A pointer to application-specific context (used when aCallback is invoked).

A subsequent call to this function replaces any previously set callback function.

Requires the feature OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE to be enabled.

otNetDataUnpublishDnsSrpService#

void otNetDataUnpublishDnsSrpService (otInstance * aInstance)

Unpublishes any previously added DNS/SRP (Anycast or Unicast) Service entry from the Thread Network Data.

Parameters
[in]aInstance

A pointer to an OpenThread instance.

OPENTHREAD_CONFIG_TMF_NETDATA_SERVICE_ENABLE must be enabled.


Definition at line 186 of file include/openthread/netdata_publisher.h

otNetDataPublishOnMeshPrefix#

otError otNetDataPublishOnMeshPrefix (otInstance * aInstance, const otBorderRouterConfig * aConfig)

Requests an on-mesh prefix to be published in the Thread Network Data.

Parameters
[in]aInstance

A pointer to an OpenThread instance.

[in]aConfig

The on-mesh prefix config to publish (MUST NOT be NULL).

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.


Definition at line 213 of file include/openthread/netdata_publisher.h

otNetDataPublishExternalRoute#

otError otNetDataPublishExternalRoute (otInstance * aInstance, const otExternalRouteConfig * aConfig)

Requests an external route prefix to be published in the Thread Network Data.

Parameters
[in]aInstance

A pointer to an OpenThread instance.

[in]aConfig

The external route config to publish (MUST NOT be NULL).

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.


Definition at line 238 of file include/openthread/netdata_publisher.h

otNetDataReplacePublishedExternalRoute#

otError otNetDataReplacePublishedExternalRoute (otInstance * aInstance, const otIp6Prefix * aPrefix, const otExternalRouteConfig * aConfig)

Replaces a previously published external route in the Thread Network Data.

Parameters
[in]aInstance

The previously published external route prefix to replace.

[in]aPrefix

The external route config to publish.

[in]aConfig

The requester (kFromUser or kFromRoutingManager module).

Requires the feature OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE to be enabled.

If there is no previously published external route matching aPrefix, this function behaves similarly to otNetDataPublishExternalRoute(), i.e., it will start the process of publishing aConfig as an external route in the Thread Network Data.

If there is a previously published route entry matching aPrefix, it will be replaced with the new prefix from aConfig.

  • If the aPrefix was already added in the Network Data, the change to the new prefix in aConfig is immediately reflected in the Network Data. This ensures that route entries in the Network Data are not abruptly removed and the transition from aPrefix to the new prefix is smooth.

  • If the old published aPrefix was not added in the Network Data, it will be replaced with the new aConfig prefix but it will not be immediately added. Instead, it will start the process of publishing it in the Network Data (monitoring the Network Data to determine when/if to add the prefix, depending on the number of similar prefixes present in the Network Data).

[out]aNumBins

Pointer to return the number of bins in histogram (array length).

[out]aBinInterval

Pointer to return the histogram bin interval length in milliseconds.

Requires OPENTHREAD_CONFIG_TX_QUEUE_STATISTICS_ENABLE.

Histogram of the time-in-queue of messages in the transmit queue is collected. The time-in-queue is tracked for direct transmissions only and is measured as the duration from when a message is added to the transmit queue until it is passed to the MAC layer for transmission or dropped.

The histogram is returned as an array of uint32_t values with aNumBins entries. The first entry in the array (at index 0) represents the number of messages with a time-in-queue less than aBinInterval. The second entry represents the number of messages with a time-in-queue greater than or equal to aBinInterval, but less than 2 * aBinInterval. And so on. The last entry represents the number of messages with time-in-queue greater than or equal to (aNumBins - 1) * aBinInterval.

The collected statistics can be reset by calling otThreadResetTimeInQueueStat(). The histogram information is collected since the OpenThread instance was initialized or since the last time statistics collection was reset by calling the otThreadResetTimeInQueueStat().

Pointers aNumBins and aBinInterval MUST NOT be NULL.
