Methods, apparatus and articles of manufacture to monitor communication paths in communication systems
First Claim
1. A method comprising:
- identifying first and second inter-network communication links of a communication system;
identifying a first plurality of router pairs associated with the first inter-network communication link;
identifying a second plurality of router pairs associated with the second inter-network communication link;
partitioning the first plurality of router pairs into a first subset of router pairs and a second subset of router pairs;
partitioning the second plurality of router pairs into a third subset of router pairs and a fourth subset of router pairs;
during a first time interval, performing first reachability tests for respective ones of the first and third subsets of router pairs;
during a second time interval, performing second reachability tests for respective ones of the second and fourth subsets of router pairs; and
changing at least one router pair in the first subset of router pairs to the second subset of router pairs.

Abstract
Example methods, apparatus and articles of manufacture to monitor communication paths in communication systems are disclosed. A disclosed example method includes identifying first and second inter-network communication links of a communication system, identifying a first plurality of router pairs associated with the first inter-network communication link, identifying a second plurality of router pairs associated with the second inter-network communication link, partitioning the first plurality of router pairs into a first subset of router pairs and a second subset of router pairs, partitioning the second plurality of router pairs into a third subset of router pairs and a fourth subset of router pairs, during a first time interval, performing first reachability tests for respective ones of the first and third subsets of router pairs, and during a second time interval, performing second reachability tests for respective ones of the second and fourth subsets of router pairs.

10. An apparatus comprising
a topology analyzer to create a list of router pairs for a communication system; -
a monitoring subset creator to partition the list of router pairs into a first subset of router pairs and a second subset of router pairs to satisfy a network test coverage criteria; and a collector to, during a first time interval, perform first reachability tests for respective ones of the first subset of router pairs, and to, during a second time interval, perform second reachability tests for respective ones of the second subset of router pairs. - View Dependent Claims (11, 12, 13, 14)
