Direct-Link Data Transmission With Network-Layer Header Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network communication, packets exchanged between communication apparatuses often carry redundant content in headers, leading to increased data transmission delay and power consumption due to the inclusion of unnecessary protocol headers.
Innovation Solution
A data transmission method that simplifies packet structure by omitting network layer headers, using only transport and data link layer headers for peer-to-peer or star connections, identified by MAC addresses and port numbers, reducing reliance on IP addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets include complete TCP/IP headers (network layer, transport layer, data link layer), then packet transmission reliability is ensured, but packet overhead increases and data transmission efficiency decreases
Solution Approach 1:
The patent extracts and removes the network layer header from the packet structure, retaining only the transport layer and data link layer headers. This extraction is justified in scenarios where communication apparatuses are directly connected without intermediate network devices, making the network layer header redundant while maintaining transmission reliability through the remaining headers.
Solution Approach 2:
The patent segments the packet structure by separating the necessary headers (transport and data link layers) from the unnecessary network layer header. This segmentation allows the packet to be optimized for specific communication scenarios where direct connection is established, reducing overhead while preserving essential transmission functions.
2Adaptability or versatility
If packets carry complete headers including network layer information, then packet routing and forwarding are enabled, but power consumption increases
Solution Approach 1:
The patent extracts and removes the network layer header that contains routing information, retaining only the data link layer and transport layer headers. This is applicable in direct connection scenarios where routing functionality is already established at the data link layer, eliminating the need for redundant network layer routing processing and reducing power consumption.
Solution Approach 2:
The patent applies partial action by including only the necessary headers for the specific communication scenario (data link and transport layers) rather than the complete set of headers (including network layer). This partial inclusion is sufficient for direct connections while avoiding the excessive processing and energy consumption associated with full header processing.
3Adaptability or versatility
If standard TCP/IP protocol is used for all communication scenarios, then protocol compatibility is ensured, but unnecessary processing overhead increases
Solution Approach 1:
The patent introduces dynamic packet structure selection based on the communication scenario. When direct connection is detected (without intermediate network devices), the packet structure is dynamically simplified to exclude the network layer header. This dynamic adaptation maintains protocol compatibility for standard scenarios while reducing processing overhead for direct connection scenarios.
Solution Approach 2:
The patent applies local quality by tailoring the packet structure to the specific local communication scenario. For direct connections, the packet uses a simplified structure without the network layer header. For connections requiring network layer routing, the complete header structure is used. This localized optimization reduces unnecessary processing overhead while maintaining compatibility where needed.
Data Source
AI summary
A data transmission method applied to data transmission between communication apparatuses is described. In the method, when a communication connection established between two communication apparatuses is a data forwarding connection without using a network layer, a structure of a packet exchanged between the communication apparatuses is simplified, the packet does not carry a network layer header, and only a transport layer header and a data link layer header that are used to implement packet transmission are reserved.
