Service disruption time determination in packet switched networks
The present invention provides an accurate and automatic technique that can take packet delay into account. A source unit (102) attached to one point of a packet-switched network under test (104) generates a stream of test packets and transmits the stream of test packets to an analysis unit (106) at...

| Zusammenfassung: | The present invention provides an accurate and automatic technique that can take packet delay into account. A source unit (102) attached to one point of a packet-switched network under test (104) generates a stream of test packets and transmits the stream of test packets to an analysis unit (106) attached to another point in the network (104). A service disruption is detected by detecting anomalous packet(s), and a service disruption time is measured by determining the time between the last packet before the disruption, and the first packet after service restoration after careful qualification of service restoration. Measurement of service disruption periods are useful in automatic protection switching (APS) networks. |
