Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile-edge computing environments, the existing routing protocols are limited in applying changes to routing paths for Internet traffic processing between Layer 2 (L2)-based switches and Layer 3 (L3)-based traffic-processing gateway nodes, hindering efficient traffic management.
Innovation Solution
An edge platform management device identifies routing events and transfers event messages, such as gratuitous ARP (GARP) messages, to update routing tables in switches, enabling efficient routing table updates and changes in edge gateway devices without relying on existing L3-based routing protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing L3-based routing protocols are used to manage Internet traffic between L2 switches and L3 gateway nodes, then routing path changes can be processed, but the system complexity increases and requires additional software maintenance
Solution Approach 1:
The patent replaces complex L3-based routing protocols with a simplified L2-based event-driven mechanism. Instead of using traditional routing protocols that require complex software processing, the system uses event messages (GARP, RTT, RTE) transmitted between L2 switches and gateway nodes to dynamically update routing tables. This substitution of mechanical routing protocol processing with event-driven L2 messaging reduces software complexity while maintaining routing adaptability.
Solution Approach 2:
The patent introduces event messages as intermediaries between L2 switches and gateway nodes. These event messages (GARP for gateway allocation, RTT for gateway failure, RTE for routing table updates) serve as mediators that carry routing information without requiring full L3 routing protocol processing. This intermediary mechanism simplifies the system by separating routing control from complex protocol processing.
2Reliability
If L3-based routing protocols are implemented, then routing functionality is provided, but maintenance costs and operational difficulty increase
Solution Approach 1:
The patent implements self-service routing where the system automatically detects routing events and updates routing tables without manual intervention. When gateway nodes are allocated, failed, or routing changes occur, the system automatically generates and processes event messages (GARP, RTT, RTE) to update routing tables in real-time. This eliminates the need for manual routing configuration and maintenance operations.
Solution Approach 2:
The patent establishes feedback mechanisms where gateway nodes and switches continuously exchange event messages to maintain accurate routing information. When routing changes occur, event messages provide feedback about the new state, and routing tables are automatically updated based on this feedback. This continuous feedback loop ensures routing reliability while eliminating manual operational complexity.
3Adaptability or versatility
If traditional routing protocols are used, then routing paths can be managed, but response time to routing changes increases
Solution Approach 1:
The patent prepares routing tables in advance by pre-establishing event message processing mechanisms. When routing changes occur, the system immediately processes event messages (GARP, RTT, RTE) without waiting for traditional routing protocol convergence. This preliminary preparation of event handling infrastructure enables rapid response to routing changes, reducing update delays compared to traditional protocols.
Solution Approach 2:
The patent implements dynamic routing table updates through real-time event message processing. Instead of static routing entries that require protocol convergence, the system dynamically updates routing tables based on incoming event messages that reflect current network state. This dynamic approach enables immediate response to routing changes as they occur, eliminating the time delays inherent in traditional protocol-based updates.
