Network Bridge IP Address Control for Cross-Domain Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in managing network bridges when their IP addresses belong to different domains, often requiring manual and complex settings or unauthorized changes.
Innovation Solution
A network bridge with an IP address control unit that determines the destination IP address and replaces the source IP address with a virtual IP address, allowing direct communication and management without additional IP address settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user terminal sets another IP address to belong to the same domain as the network bridge, then direct communication and management are enabled, but the user terminal requires authorization to set or change IP addresses and manual settings become complicated
Solution Approach 1:
The network bridge acts as an intermediary by introducing a virtual IP address that belongs to the same domain as the network bridge's IP address. When the bridge receives a management packet, it replaces the source IP address with the virtual IP address, enabling the user terminal to communicate with the bridge as if they were in the same domain without requiring the user terminal to actually change its IP address configuration.
Solution Approach 2:
The network bridge creates a virtual IP address that copies the domain characteristics of the bridge's own IP address. This virtual IP address serves as a representative copy that allows management communication without requiring the user terminal to physically adopt a different IP address configuration, thus simplifying the operation while maintaining domain compatibility.
2Device complexity
If the user terminal uses its existing IP address from a different domain, then no additional IP address settings are needed, but the user terminal cannot directly manage the network bridge due to domain mismatch
Solution Approach 1:
The network bridge serves as a mediator by implementing an IP address replacement mechanism. When receiving management packets from user terminals with different domain IP addresses, the bridge replaces the source IP address field with a virtual IP address that matches its own domain, thereby enabling management operations without requiring the user terminal to change its IP address configuration.
3Reliability
If manual IP address settings are performed to enable management, then domain compatibility is achieved, but the process requires complicated steps and time
Solution Approach 1:
The network bridge performs preliminary action by pre-configuring a virtual IP address that matches its domain before any management operations occur. This pre-prepared virtual IP address is stored in the bridge's memory and automatically used for IP address replacement when management packets are received, eliminating the need for users to perform time-consuming manual IP address configuration steps.
Solution Approach 2:
The network bridge provides self-service by automatically performing IP address replacement using its pre-configured virtual IP address. The bridge independently handles the domain compatibility issue by modifying the source IP address field in received packets, without requiring user intervention or manual configuration, thus saving time and reducing operational complexity.

AI summary
A network bridge and a network management method are provided, and the network bridge includes a first network interface, an IP address control unit, and an application unit. The first network interface receives a first packet sent from a first apparatus in a first network. The IP address control unit includes an address determination unit and an address replacement unit. The address determination unit determines whether an IP address of the network bridge is in a destination IP address field of the first packet. The address replacement unit replaces an IP address of the first apparatus in a source IP address field of the first packet with a virtual IP address when the IP address of the network bridge is in the destination IP address field of the first packet. The application unit receives the replaced first packet from the IP address control unit and processes the replaced first packet.
