Abstract: Example methods, apparatus and articles of manufacture to monitor communication paths in communication systems are disclosed. An example method includes identifying links of a communication system, the links communicatively coupling router pairs, identifying communication paths in the communication system, each of the communication paths being routed via one or more of the links, testing the links during a first interval by testing at least a first portion of the communication paths, testing the links during the second interval by testing at least a second portion of the communication paths, changing the first portion of the communication paths to include at least one of the communication paths from the second portion of the communication paths such that testing the first portion of the communication paths and testing the second portion of the communication paths collectively test each of the links, and identifying a link failure based on the testing.

Abstract: A method and apparatus for diagnosing and isolating label-switched-path impairments in a network are disclosed. For example, the present method receives an impairment notification indicating a potential impairment for at least one label switched path between a source device and a destination device. The method then identifies all routers along each of the at least one label switched path. The method then determines automatically whether each of the routers along each of the at least one label switched path is enabled for exchanging label mapping information. Finally, the method identifies at least one of the at least one label switched path as being impaired if at least one of the routers on the switched path is deemed not enabled for exchanging label mapping information.
