Abstract: A process is provided for auditing a communication session between a source connected to a first node of a service network and a destination connected to a second node of the service network. At least one of the source and destination are outside of the service network and are in communication with an interface of the service network. In the process, flow activity of selected traffic outside of the service network, as well as in or at an interface of the service network, is captured between the source and the destination at selected states and points in time during the communication session. Comparisons are conducted between the flow activity captured outside of the service network and flow activity captured in or at an interface of the service network to audit the delivery of services in the service network.

Abstract: Flow activity of selected traffic is captured between a source and a destination at selected states and points in time during a communication session between nodes of a service network. The flow activity includes a flow descriptor for selected datagrams placed in the service network. The flow activity also includes either a service identifier for the selected datagrams which identifies a service interface in the service network that the datagram is transmitted to or received from, or any service labels that are within or appended to the selected datagrams, wherein the service labels reference the service to be given to the datagrams. The service being provisioned on predefined service interfaces is identified. The identified provisioned service and the service identifiers or service labels are used to determine the service provisioned for the datagrams associated with the captured flow activity.
