Abstract
An abnormal point locating method includes: a link primary abnormality judgment procedure that acquires information on a link through which each observation flow passes, locates a link through which an observation flow observed at an observation point passes, and judges whether the located link is normal or abnormal based on the observation flow; and a link secondary abnormality judgment procedure that judges a probability of abnormality based on a result of the link primary abnormality judgment procedure by using a connection relationship as seen from each observation point.
Claims17
A non-transitory computer-readable recording medium storing an abnormal point locating program allowing a computer to execute:
- acquiring information on a link through which observation flow passes,
- locating a link through which the observation flow passes, on an observation point-by-observation point basis,
- first judging whether the located link is normal or abnormal based on whether the observation flow is normal or abnormal when the observation flow is observed on a basis of an observation point;
- and
- second judging a probability of abnormality of a link on an observation point-by-observation point basis based on a result obtained by the first judging by using a tree-shaped upper/lower link connection relationship as seen from each observation point.
An abnormal point locating apparatus for locating an abnormal point of a network, the apparatus comprising:
- a memory which stores a program;
- and
- a processor which executes, based on the program, a procedure comprising:
- acquiring information on a link through which observation flow passes;
- locating a link through which the observation flow passes, on an observation point-by-observation point basis, and
- first judging whether the located link is normal or abnormal based on whether the observation flow is normal or abnormal when the observation flow is observed on a basis of an observation point;
- and
- second judging that judges a probability of abnormality of a link on an observation point-by-observation point basis based on a result obtained by the first judging by using a tree-shaped upper/lower link connection relationship as seen from each observation point.
An abnormal point locating system in which a plurality of flow quality measurement agents and an abnormal point locating apparatus are connected in such a way that data communication therebetween is possible,
- the flow quality measurement agents each include:
- a memory which stores a program;
- and
- a processor which executes, based on the program, a procedure comprising:
- acquiring information on a link through which observation flow passes,
- locating a link through which the observation flow passes, on an observation point-by-observation point basis, and
- first judging whether the located link is normal or abnormal based on whether the observation flow is normal or abnormal when the observation flow is observed on a basis of an observation point;
- second judging to judge a probability of abnormality of a link based on a result obtained by the first judging by using a tree-shaped upper/lower link connection relationship as seen from an observation point;
- and
- notifying the abnormal point locating apparatus based on a result obtained by the second judging,
- acquiring the result obtained by the second judging from each flow quality measurement agents.
An abnormal point locating method locating an abnormal point of a network, the method comprising:
- acquiring, from a network path information storing unit storing information on a passage path through which an observation flow passes, information on a link through which each observation flow passes,
- locating a link through which the observation flow passes, on an observation point-by-observation point basis, and
- first judging whether the located link is normal or abnormal based on whether the observation flow is normal or abnormal when the observation flow is observed on a basis of an observation point;
- and
- second judging that judges a probability of abnormality of a link on an observation point-by-observation point basis based on a result obtained by the first judging by using a tree-shaped upper/lower link connection relationship as seen from each observation point.
