Inner Header Routing for Mobile Network Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile telecommunications networks, existing technologies fail to accurately identify and direct data packets based on their original source and destination addresses, as this information is not provided in the outer headers, leading to inefficiencies in data traffic management and routing.
Innovation Solution
The implementation of inner headers within data packets that contain the original source and destination addresses, allowing routing components to accurately route, inspect, and manage data traffic by referencing this information, even when outer headers are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If outer headers are added to data packets for mobile network routing, then network traffic management becomes possible, but the original source and destination addresses become inaccessible for routing decisions
Solution Approach 1:
The patent embeds the original IP header (containing source and destination addresses) within the GRE tunnel packet structure. The inner header is nested inside the outer header, allowing both headers to coexist. The routing component can access the outer header for network routing while also extracting and using the inner header's original addresses for routing decisions, quality of service policies, and traffic management.
Solution Approach 2:
The patent divides the packet header information into two distinct segments: the outer header containing mobile network routing information (GRE headers with mobile device and network address) and the inner header containing the original IP header with source and destination addresses. This segmentation allows each segment to serve its specific purpose without interfering with the other, enabling dual routing capabilities.
2Productivity
If routing components only use outer header information, then simple routing is possible, but precise routing based on original destinations cannot be achieved
Solution Approach 1:
The original source and destination addresses are preserved in the inner header before the packet enters the mobile network tunnel. The routing component is pre-configured to inspect both outer and inner headers, enabling it to make routing decisions based on original destinations even while packets traverse through the tunnel infrastructure. This preliminary preservation of address information enables precise routing without requiring complex real-time extraction.
3Reliability
If inner headers are inspected and used for routing, then precise data packet management is achieved, but processing complexity increases
Solution Approach 1:
The routing component creates a copy of the inner header information (original source and destination addresses) for routing decisions while leaving the original packet structure intact. This copying approach allows the system to use the embedded header information for routing without requiring complex parsing or modification of the nested packet structure, reducing processing overhead while maintaining routing accuracy.
