Methods, apparatus and articles of manufacture to monitor communication paths in communication systems
First Claim
1. A method, comprising:
- identifying a plurality of communication links of a communication system, the communication links communicatively coupling routers in the communication system;
identifying a plurality of communication paths in the communication system, each of the communication paths being routed via one or more of the communication links;
testing the plurality of communication links during a first interval by testing at least a first portion of the communication paths;
testing the plurality of communication links during a second interval by testing at least a second portion of the communication paths different from the first 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 plurality of communication links; and
identifying a communication link failure based on the testing.

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 routers, 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.

5. A method, comprising:
-
identifying a plurality of communication links of a communication system, the communication links communicatively coupling routers in the communication system; identifying a plurality of communication paths in the communication system, each of the communication paths being routed via one or more of the communication links; testing the plurality of communication links during a first interval by testing at least a first portion of the communication paths; testing the plurality of communication links during a second interval by testing at least a second portion of the communication paths different from the first portion of the communication paths; detecting at least one of a removed communication link or a removed communication path; 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 remaining in the plurality of communication links; and identifying a communication link failure based on the testing. - View Dependent Claims (6, 7)

8. An apparatus, comprising:
-
a topology analyzer to; identify a plurality of communication links of a communication system, the communication links communicatively coupling routers in the communication system; identify a plurality of communication paths in the communication system, each of the communication paths being routed via one or more of the communication links; and detect at least one of a removed communication link or a removed communication path; and a collector to; test the plurality of communication links during a first interval by testing at least a first portion of the communication paths; test the plurality of communication links during a second interval by testing at least a second portion of the communication paths different from the first portion of the communication paths; change 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 plurality of communication links; and identify a communication link failure based on the testing. - View Dependent Claims (9, 10, 11)
