Method and apparatus for detecting and localizing an anomaly for a network

摘要

A method and apparatus for detecting and localizing an anomaly for a network are disclosed. For example, the method sends a first set of probe packets on at least one path of the network, and detects a performance anomaly on a first path of the at least one path. The method then identifies at least one link on the first path that is responsible for the performance anomaly by applying a second set of probe packets.

1. A method for detecting a performance anomaly for a network, the method comprising:
sending, by a processor, a first set of probe packets on a first path of the network; detecting, by the processor, a first indication of the performance anomaly on the first path, wherein the first indication of the performance anomaly on the first path is detected via the first set of probe packets; selecting, by the processor, a second path of the network that only partially intersects a portion of the first path, wherein the second path includes a link that is not on the first path; sending, by the processor, a second set of probe packets on the second path, wherein the selecting and the sending are performed in response to the detecting the first indication of the performance anomaly on the first path; detecting, by the processor, a second indication of the performance anomaly on the second path, wherein the second indication of the performance anomaly on the second path is detected via the second set of probe packets; and identifying, by the processor, a link that is on both the first path and on the second path that is responsible for the performance anomaly.
