Abstract: Example methods and systems for a network management entity to perform configuration change monitoring. One example method may comprise receiving a request to monitor a datapath to which a configuration change is applicable. The datapath may include multiple network elements. The method may also comprise instructing the first host to inject, at a first network element, one or more trace packets for transmission along the datapath to a second network element. The method may further comprise: obtaining state information associated with the configuration change, and detecting that an operating condition associated with the datapath is affected by the configuration change based on the state information.

Abstract: Example methods are provided for a network management entity to perform network configuration failure diagnosis in a software-defined networking (SDN) environment. The method may comprise receiving a request to diagnose a network configuration failure; and generating and sending control information to a host to cause the host to inject, at a first network element, a diagnostic packet for transmission along a datapath to a configuration server via multiple second network elements. The diagnostic packet may be configured according to a network configuration protocol supported by the configuration server. The method may also comprise: receiving report information associated with the diagnostic packet from at least one of the following: the first network element, the multiple second network elements and the configuration server; and based on the report information, determining a diagnosis result associated with the network configuration failure.

Abstract: Example methods are provided for a network management entity to perform query failure diagnosis in a software-defined networking (SDN) environment. The method may comprise receiving a request to diagnose a query failure; and generating and sending control information to a host to cause the host to inject, at a first network element, a diagnostic packet for transmission along a datapath to a query failure via multiple second network elements. The diagnostic packet may be a query configured according to a query protocol supported by the query server. The method may also comprise: receiving report information associated with the diagnostic packet from at least one of the following: the first network element, the multiple second network elements and the query failure; and based on the report information, determining a diagnosis result associated with the query failure.
