Interface FlowRuleService

  • All Superinterfaces:
    ListenerService<FlowRuleEvent,​FlowRuleListener>
    public interface FlowRuleService
extends ListenerService<FlowRuleEvent,​FlowRuleListener>
    Service for injecting flow rules into the environment and for obtaining information about flow rules already in the environment. This implements semantics of a distributed authoritative flow table where the master copy of the flow rules lies with the controller and the devices hold only the 'cached' copy.

        default java.lang.Iterable<FlowEntry> getFlowEntriesByLiveType​(DeviceId deviceId,
                                                               FlowEntry.FlowLiveType liveType)
        Returns a list of rules filtered by device id and flow live type.
        Parameters:
        deviceId - the device id to lookup
        liveType - the flow live type to lookup
        Returns:
        collection of flow entries

      • getFlowEntriesByState

        default java.lang.Iterable<FlowEntry> getFlowEntriesByState​(DeviceId deviceId,
                                                            FlowEntry.FlowEntryState flowState)
        Returns a list of rules filtered by device id and flow state.
        Parameters:
        deviceId - the device id to lookup
        flowState - the flow state to lookup
        Returns:
        collection of flow entries

      • applyFlowRules

        void applyFlowRules​(FlowRule... flowRules)
        Applies the specified flow rules onto their respective devices. These flow rules will be retained by the system and re-applied anytime the device reconnects to the controller.
        Parameters:
        flowRules - one or more flow rules

      • purgeFlowRules

        void purgeFlowRules​(DeviceId deviceId)
        Purges all the flow rules on the specified device.
        Parameters:
        deviceId - device identifier

      • removeFlowRules

        void removeFlowRules​(FlowRule... flowRules)
        Removes the specified flow rules from their respective devices. If the device is not presently connected to the controller, these flow will be removed once the device reconnects.
        Parameters:
        flowRules - one or more flow rules

      • removeFlowRulesById

        void removeFlowRulesById​(ApplicationId appId)
        Removes all rules submitted by a particular application.
        Parameters:
        appId - ID of application whose flows will be removed

      • getFlowEntriesById

        java.lang.Iterable<FlowEntry> getFlowEntriesById​(ApplicationId id)
        Returns a list of rules with this application ID.
        Parameters:
        id - the application ID to look up
        Returns:
        collection of flow rules

      • getFlowRulesByGroupId

        java.lang.Iterable<FlowRule> getFlowRulesByGroupId​(ApplicationId appId,
                                                   short groupId)
        Returns a list of rules filtered by application and group id.

        Note that the group concept here is simply a logical grouping of flows. This is not the same as a group in the GroupService, and this method will not return flows that are mapped to a particular Group.

        Parameters:
        appId - the application ID to look up
        groupId - the group ID to look up
        Returns:
        collection of flow rules

      • apply

        void apply​(FlowRuleOperations ops)
        Applies a batch operation of FlowRules.
        Parameters:
        ops - batch operation to apply

      • getFlowTableStatistics

        java.lang.Iterable<TableStatisticsEntry> getFlowTableStatistics​(DeviceId deviceId)
        Returns the collection of flow table statistics of the specified device.
        Parameters:
        deviceId - device identifier
        Returns:
        collection of flow table statistics

      • getActiveFlowRuleCount

        @Deprecated
default long getActiveFlowRuleCount​(DeviceId deviceId)
        Deprecated.
        since 2.1
