Abstract
Official abstract text for this publication.
Conventional network quality monitoring systems require high monitoring cost, because: physical maintenance cost is high, since monitors are required to install on many portion of the network; the number of monitoring flows is apt to increase; the cost for information synchronization between monitors is required; and the network cost to collect information from apparatuses is required. In the present invention, based on a network whose route is definable by an external controller and changing the monitoring flow route appropriately, it is possible to perform monitoring of the communication quality under a small number of monitoring terminals and flows. Further, the role of the monitoring flow is divided into the monitoring flows to monitor the quality degradation occurrence and to specify the quality degradation point. The former is used for normal time, and the latter is for the quality degradation time. Consequently, the network monitoring system reducing the cost is proposed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A communication quality monitoring system, comprising: a normal monitoring route planning unit configured to determine a normal monitoring route for sensing an event of a quality degradation having occurred in a quality monitor area of a network formed by a packet transfer apparatus whose packet transfer route is controlled by an external controller; a quality degrading point monitoring route planning unit configured to determine, when a quality degr…
