    Patent number: 9565163
    Abstract: Verification of continuity for a network service path that includes at least one network function that blocks test packets may be achieved by providing a bypass mechanism to bypass test packets around the at least one network function that blocks test packets. Verification of continuity may be done when the network service is available for active use or when it is not ready for active use. Detection of a continuity problem leads to more detailed diagnostic work.
