Solution Overview
Problem
Existing multi-node network communication systems face challenges in increasing processing speed and reducing power consumption while maintaining compatibility with established protocols like IEEE 802.1CB, especially in demanding environments such as automotive and industrial settings.
Innovation Solution
The method involves configuring payload headers and data link layers within a multi-node network to efficiently route payload data between nodal circuits, using a data link layer with associated payload headers to convey data and a network layer with routing information to identify the destination nodal circuit, allowing for efficient data transmission and processing.

Engineering Contradiction Analysis
1Speed
If standard IEEE 802.1CB protocols are used for multi-node network communication, then protocol compatibility and security are maintained, but processing speed is limited and power consumption is high
Solution Approach 1:
The patent segments the routing information into two distinct parts: network layer routing headers that remain unchanged for compatibility, and data link layer payload headers that are configured by intermediate nodes to identify actual source and destination addresses. This segmentation allows standard protocols to be maintained while enabling optimized routing operations.
Solution Approach 2:
The patent introduces an intermediate node (such as a switch) that acts as a mediator between the sending and selected nodes. This intermediary configures the payload header to reflect the actual source and destination addresses, enabling efficient routing decisions without requiring end nodes to process complex routing logic, thus improving processing speed while maintaining protocol compatibility.
2Productivity
If intermediate nodes configure payload headers to identify actual source and destination, then routing efficiency is improved, but data link layer complexity increases
Solution Approach 1:
The intermediate node performs preliminary configuration of the payload header before forwarding the data frame. By pre-configuring the source and destination addresses in the payload header based on the network layer routing information, the intermediate node enables the selected node to quickly identify and process the frame without complex runtime routing decisions, thus improving transmission efficiency.
Solution Approach 2:
The intermediate node creates a copy of the routing information from the network layer header and uses it to configure the data link layer payload header. This copying mechanism allows the payload header to reflect the actual communication endpoints while the network layer header maintains the original routing path information, enabling efficient routing without increasing overall system complexity.
3Use of energy by stationary object
If network layer routing information is used to identify destination, then routing flexibility is maintained, but processing overhead and power consumption increase
Solution Approach 1:
The patent extracts the critical routing information (source and destination addresses) from the network layer header and places it in the data link layer payload header. This extraction allows the selected node to quickly identify the intended recipient using the payload header information without having to process the entire network layer routing structure, thereby reducing processing overhead and power consumption while maintaining routing flexibility.

AI summary
Aspects are directed toward a data-communication approach using an arrangement of node-node communication according to a protocol involving layered routing of payload as might be similar to layered-based communication-protocol standards used in automotive applications. A particular payload is conveyed between nodes via a protocol having a data link layer and a network layer, the latter being used to indicate to which node(s) the payload is to be routed. For compatibility with standard(s), the protocol accommodates transfer of data between nodes by permitting for use of both the data link and network layers. In some implementations, to increase efficiency and processing overhead for payload transmissions, the protocol does not require use of the network layer to indicate where to transfer the payload.
