Network Management Device for Mixed IPv4 IPv6 Node Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networks with both IPv4 and IPv6 protocols, existing management devices struggle to correctly identify and display address information from nodes supporting both protocols as a single entity, often mistakenly treating multiple addresses as belonging to separate nodes.
Innovation Solution
A management device that sends request packets using a single protocol to obtain address information from nodes, and displays this information in a way that recognizes multiple addresses as belonging to a single node, using a representative address selection mechanism to prevent misidentification, and allows user-defined rules for address prioritization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the management device obtains address information from nodes using broadcast/multicast requests in a mixed IPv4-IPv6 network, then it can collect address information from both IPv4 and IPv6 nodes, but it mistakenly treats multiple addresses as belonging to separate nodes instead of recognizing them as a single node
Solution Approach 1:
The management device uses feedback mechanisms by sending request packets to nodes and analyzing the response packets. When a node responds, it provides feedback containing its address information. The management device then uses this feedback to identify whether multiple addresses belong to the same node by examining the response packet structure and node identity information, thereby resolving the contradiction between network adaptability and identification accuracy.
2Loss of information
If the management device displays all obtained address information, then complete information is provided, but excessive detail is shown which may confuse users about which addresses belong to a single node
Solution Approach 1:
The management device applies segmentation by dividing the display of address information into logical groups corresponding to individual nodes. Instead of presenting a flat list of all addresses, it segments the information hierarchy to show which addresses belong to which node, making the relationship clear to users while maintaining complete address information.
Solution Approach 2:
The management device adds a dimensional organization to address information display by introducing a node-level grouping dimension. Addresses are not just listed linearly but are organized in a hierarchical structure where the first dimension is node identity and the second dimension is address detail, enabling users to understand the relationship between nodes and their addresses more easily.

AI summary
According to an aspect of the invention, there is provided a management device used in a network to which nodes are connected. The management device includes an information requesting unit to send out a request packet requesting address information concerning addresses of each node through the network while using a predetermined single protocol, an information receiving unit to receive the address information retuned from each node as a response to the request packet, and an information displaying unit to display addresses contained in the received address information such that if two or more addresses are in the address information received from a single node, the two or more addresses are treated as addresses belonging to the single node.
