Network Communication Device Packet Routing Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IP sharing devices waste time and efficiency by translating internal packet addresses twice before forwarding them to the Internet, due to the need for address translation in both the address translation module and the IP routing module.
Innovation Solution
A network communication device with a transceiver module, address translation module, control buffer module, and IP routing module that determines if packet addresses need translation, marks translated addresses with flags, and directly forwards packets without redundant translation by querying the control buffer module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the address translation module translates addresses of internal packets and sends them to the IP routing module for routing, then the packets can be routed correctly, but the packets are sent to the address translation module twice causing unnecessary time consumption and decreasing utilization efficiency
Solution Approach 1:
The address translation module performs address translation in advance and marks translated packets with flags before sending them to the IP routing module. When packets return from routing, the control buffer module checks the flags to determine if addresses have already been translated, avoiding redundant translation operations and reducing packet forwarding time while maintaining routing correctness
Solution Approach 2:
The control buffer module maintains a feedback mechanism by recording flags that indicate whether packet addresses have been translated. This feedback information allows the address translation module to quickly determine if re-translation is necessary, preventing unnecessary processing and optimizing the packet forwarding path
2Productivity
If the address translation module translates all packet addresses before routing, then all packets can be forwarded to the Internet, but unnecessary translation operations are performed on packets that do not require translation
Solution Approach 1:
Instead of translating addresses of all packets, the system performs partial translation only when necessary. The flag mechanism allows the address translation module to identify and skip packets that have already been translated or do not require translation, reducing unnecessary processing operations and energy consumption while maintaining high packet forwarding throughput

AI summary
A network communication device includes a transceiver module, an address translation module, a control buffer module, an IP routing module, and a processor. The transceiver module is configured for forwarding packets. The address translation module determines if addresses of the forwarded packets need to be translated and translates the addresses of the forwarded packets when needed. Next, the address translation module marks the packets of translated addresses with flags and records the flags in the control buffer module. The IP routing module routes the forwarded packets from the address translation module and sends the forwarded packets back to the address translation module. The address translation module receives the forwarded packets from the IP routing module, determines if the addresses of the forwarded packets have been translated by querying the flags in the control buffer module, and sends the forwarded packets that have been translated to the transceiver module.
