Virtual L2 Integration for Cloud Processing of Edge Protocol Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud environments struggle to effectively integrate and process domain-specific protocols operating at OSI layer 2 (L2) due to limitations in higher layer abstractions, requiring complex conversions and hardware modifications, which hinder seamless connectivity and resource management between edge devices and cloud systems.
Innovation Solution
A cloud layer management (CLM) agent dynamically instantiates virtual L2 devices in a cloud computing environment, using a relay tool to establish network topology and manage domain-specific data sources, enabling seamless communication without altering application code, and supports error correction across OSI layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cloud environments use higher layer abstractions (OSI L3 and above) for communication, then network management and resource allocation are simplified, but integration with domain-specific L2 protocols becomes difficult and requires complex conversions
Solution Approach 1:
The patent introduces a cloud layer management (CLM) agent as an intermediary component that bridges OSI L2 domain-specific protocols and higher layer cloud infrastructure. The CLM agent receives L2 frames from edge devices, performs error detection and correction, and enables communication without requiring complex protocol conversions across the entire system
Solution Approach 2:
The patent segments the protocol handling functions by introducing virtual L2 devices that operate at the L2 layer while maintaining separation from higher layer abstractions. This segmentation allows L2 protocol processing to be handled independently by specialized components (CLM agents) while the rest of the cloud infrastructure continues to use standard L3+ protocols
2Adaptability or versatility
If hardware modifications are implemented to support L2 protocol integration, then protocol compatibility is achieved, but system complexity and cost increase
Solution Approach 1:
The patent replaces hardware-based protocol handling with software-based solutions. Virtual L2 devices and CLM agents implemented in software provide L2 protocol support without requiring physical hardware modifications, thereby maintaining protocol compatibility while avoiding hardware complexity
Solution Approach 2:
The CLM agent provides universal L2 protocol handling capabilities that work across multiple domain-specific protocols (CAN, LIN, FlexRay, Ethernet). This multi-functional approach achieves broad protocol compatibility through a single software component rather than requiring separate hardware modifications for each protocol
3Reliability
If error correction is implemented across OSI layers, then data reliability is improved, but processing time and computational resources increase
Solution Approach 1:
The patent implements error detection and correction as preliminary actions at the L2 layer before data proceeds to higher layers. By performing error correction early in the communication stack, the system ensures data reliability without requiring repeated error handling at higher layers, thereby reducing overall processing time
Data Source
AI summary
A system and method of processing datasets that are compliant to a layer 2 (L2) protocol of an open systems interconnection (OSI) model in a cloud computing environment on behalf of an edge computing environment. The method includes receiving, from the edge computing device, a set of L2 frames. The method includes detecting one or more errors in the set of L2 frames based on an L2 protocol of the OSI model. The method includes correcting the one or more errors in the set of L2 frames to generate a corrected set of L2 frames. The method includes generating, by a processing device of a cloud computing system, a processed dataset based on the corrected set of L2 frames.
