Wireless Adaptor Address Translation for Network Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network transmission methods are inefficient due to the reliance on hardware addresses for message routing, leading to increased ARP requests and lack of integration between local networks, which hampers transmission efficiency and security, especially when concealing source host addresses.
Innovation Solution
A wireless adaptor and method that records hardware and protocol addresses in a bridge device, allowing for transformation and replacement of hardware addresses with bridge addresses, enabling efficient message transmission and reducing ARP requests while integrating local networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hardware address based routing is used in Ethernet transmission, then message transmission can proceed at the data link layer, but the number of ARP requests increases and transmission efficiency decreases
Solution Approach 1:
The patent pre-establishes a correspondence relationship table between hardware addresses and protocol addresses in the bridge device before message transmission occurs. This preliminary action allows the bridge to perform address translation using pre-computed mappings, eliminating the need for dynamic ARP requests during actual message transmission and thereby improving transmission efficiency while reducing time loss.
2Adaptability or versatility
If bridge device uses hardware address for message filtering, then local networks can be linked together, but the capability to conceal source host hardware address is lost
Solution Approach 1:
The patent introduces the bridge device as an intermediary that performs address translation between hardware addresses and protocol addresses. The bridge replaces the source host's hardware address with its own bridge hardware address in transmitted messages, thereby concealing the original source host's hardware address while still enabling proper message routing and network integration through the established correspondence relationships.
3Ease of operation
If ARP broadcast packets are transmitted to query hardware addresses, then address resolution can be achieved dynamically, but network traffic increases and transmission efficiency decreases
Solution Approach 1:
The patent pre-establishes address correspondence relationships in the bridge device before actual message transmission. This preliminary action eliminates the need for dynamic ARP broadcast packets during normal operation, as the bridge can perform address translation using pre-computed mappings stored in its correspondence relationship table, thereby reducing network traffic volume while maintaining address resolution functionality.

AI summary
A method for transmitting and receiving a message is provided. The method includes steps of providing a bridge device having a bridge hardware address and a first end, receiving a first message including a first hardware address, a first protocol address and a second protocol address from the first end, recording the first hardware address and the first protocol address on a table, replacing the first hardware address with the bridge hardware address, transmitting the first message to a second end having a second hardware address corresponding to the second protocol address; transmitting a second message including the first protocol address, the second protocol address, the bridge hardware address, and the second hardware address from the second end to the bridge device, replacing the bridge hardware address with the first hardware address according to the table; and transmitting the second message to the first end.
