Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional packet transmission routing is used, then transmission speed and simplicity are maintained, but carbon emissions are not optimized and network sustainability deteriorates
Solution Approach 1:
The system performs preliminary carbon emission predictions for all devices in the network before packet transmission occurs. Carbon emission maps are pre-calculated and stored, allowing routing decisions to be made quickly without real-time computation overhead. This preliminary action enables low-carbon routing without adding significant complexity to the transmission process.
Solution Approach 2:
The patent introduces carbon emission maps as an intermediary data structure that mediates between network traffic and routing decisions. These maps contain pre-computed carbon emission information that guides packet routing without requiring complex real-time calculations. The emission maps act as a lookup table that simplifies the routing decision-making process while achieving carbon optimization.
2Object-affected harmful factors
If carbon emission prediction is performed for each device, then routing optimization is achieved, but computational overhead and processing time increase
Solution Approach 1:
Carbon emission predictions are performed in advance and stored in carbon emission maps before packets need to be routed. The system pre-calculates emission values for all devices based on historical data, device characteristics, and environmental factors, eliminating the need for time-consuming real-time predictions during packet transmission.
Solution Approach 2:
The patent extracts carbon emission information from complex real-time calculations and stores it as pre-computed values in carbon emission maps. This extraction separates the computationally intensive emission prediction from the time-sensitive packet routing process, allowing rapid routing decisions based on pre-existing emission data.
3Productivity
If existing routing methods are used, then transmission efficiency is maintained, but environmental sustainability and resource optimization deteriorate
Solution Approach 1:
The system dynamically routes packets based on carbon emission maps that reflect current network conditions and environmental factors. Rather than using static routing tables, the emission maps are updated to capture changing conditions such as device power states, traffic patterns, and environmental data, enabling adaptive routing that optimizes both efficiency and sustainability.
Solution Approach 2:
The patent changes the routing parameter from traditional metrics like shortest path or least hops to carbon emission levels. By using emission values as the primary routing parameter, the system can achieve comparable transmission efficiency while significantly reducing environmental impact. The emission maps provide the necessary parameter transformation to enable this shift.

AI summary
A computer-implemented method (CIM), according to one embodiment, includes, in response to receiving a first packet from a first application, performing a predetermined process for determining a low carbon emission transmission route along a source to a target. The predetermined process includes predicting for each of a plurality of devices between the source and the target, carbon emissions that would result from using the device for transmitting the first packet, and generating a carbon emission map. The predetermined process further includes selecting, from the carbon emission map, a first transmission route that hops along at least one of the devices, where the first transmission route is selected over a second transmission route based on the second transmission route having a greater carbon emission than the first transmission route. The CIM further includes causing the first packet to be transmitted from the source to the target along the first transmission route.
