Real-time customer packet traffic is instrumented to determine measured delays between two or more points along a path actually traveled by a packet, such as within or external to one or more packet switching devices. These measurements may include delays within a packet switching device other than the ingress and egress time of a packet. These measured delays can be used to determine whether or not the performance of a packet switching device or network meets desired levels, especially for complying with a Service Level Agreement.
