Network Management Apparatus for Traffic Volume Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network management techniques face challenges in accurately monitoring traffic volume across large networks due to increased load on switches when collecting statistical information, leading to potential estimation errors.
Innovation Solution
A management apparatus and method that acquires topology information and selects monitoring target switches to reduce the number of switches from which statistical information is collected, focusing on endpoints of links within the network to minimize load and enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If statistical information is collected from all switches in the network, then the accuracy of traffic volume monitoring is improved, but the load on the network and switches increases
Solution Approach 1:
The patent segments the network into multiple groups, where each group contains a set of switches and a designated monitoring target switch. This segmentation allows statistical information to be collected from selected representative switches in each group rather than all switches, reducing overall network load while maintaining monitoring accuracy through intelligent selection of monitoring targets based on link topology and traffic characteristics.
2Measurement precision
If statistical information is collected at shorter time intervals, then the accuracy of traffic volume monitoring is improved, but the load on switches increases
Solution Approach 1:
The patent extracts and focuses monitoring efforts on specific monitoring target switches that are strategically selected based on network topology and link characteristics. By concentrating statistical information collection on these key switches rather than distributing it across all switches at high frequency, the system achieves accurate traffic volume monitoring while reducing the processing load on individual switches.
3Measurement precision
If monitoring target switches are selected based on link topology, then the accuracy of traffic volume estimation is improved, but the complexity of switch selection increases
Solution Approach 1:
The monitoring target switch selection is performed automatically by the management apparatus based on link topology information and predetermined selection criteria. The system self-determines which switches should be monitoring targets by analyzing the network topology and applying selection rules, eliminating the need for manual configuration or complex external intervention while ensuring accurate representation of network traffic patterns.

AI summary
[Problem] To reduce a load caused to acquire a traffic volume, and contribute to grasp of a precise traffic volume. [Solution] A management apparatus is provided with: a topology information acquisition unit that acquires topology information regarding a group of links having, among a first group of switches included in a network, a switch included in the first group of switches at an end point; a switch selection unit that selects one or more switches to be monitored, which are a set of switches including either of the end points of each link constituting the group of links; and a statistical information acquisition unit that acquires statistical information from the switches being monitored.
