Network Traffic Routing via Alternative Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network technologies face limitations in efficiently routing network traffic to third-party resources, often resulting in suboptimal performance due to reliance on default paths that may not provide the best connectivity, especially when accessing resources outside the internal network domain.
Innovation Solution
The method involves determining multiple paths to a third-party network resource, combining performance scores for both internal and external network domain paths, and rerouting traffic along a path with superior performance, using alternative network devices and paths to optimize traffic flow and reduce reliance on default routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic is routed through a remote network location (default path), then network connectivity is maintained, but network performance and response time deteriorate
Solution Approach 1:
The system dynamically selects between default and alternative paths based on real-time performance metrics. Network devices monitor bandwidth availability, latency, and other performance indicators, then adaptively route traffic through the optimal path (default or alternative) to maintain both connectivity reliability and performance speed.
Solution Approach 2:
The invention changes routing parameters by introducing alternative network paths with different performance characteristics. By evaluating parameters such as bandwidth availability, latency, and path cost, the system selects the path that optimizes the balance between connectivity reliability and transmission speed.
2Reliability
If traffic is routed through the internal network domain, then connectivity to third-party resources is established, but bandwidth usage and congestion increase
Solution Approach 1:
The network routing is segmented into multiple paths: default internal network paths and alternative external network paths. By dividing traffic routing options into distinct segments, the system can direct specific traffic flows through alternative paths that bypass the internal network domain, thereby maintaining connectivity while reducing internal bandwidth consumption and congestion.
Solution Approach 2:
Alternative network devices and paths act as intermediaries between internal network devices and third-party resources. These intermediary paths provide indirect routing options that achieve the same connectivity goal while consuming less internal network bandwidth and reducing congestion in the core network domain.
3Productivity
If multiple paths are evaluated and alternative routing is implemented, then network performance is optimized, but system complexity increases
Solution Approach 1:
Network devices automatically perform path evaluation, performance monitoring, and routing decisions without requiring complex centralized control. Each network device independently assesses alternative paths using predefined performance metrics and autonomously selects the optimal route, thereby optimizing network performance while avoiding the complexity of centralized routing management systems.
4Productivity
If alternative network devices are used for routing, then traffic flow optimization is achieved, but device configuration complexity increases
Solution Approach 1:
Alternative network devices are designed with universal routing capabilities that allow them to function both as default path devices and as alternative path devices. This multi-functionality enables the same device types to be used throughout the network, simplifying configuration and management while still providing optimized traffic flow through alternative routing options.

AI summary
A method may include identifying an address within a packet of a traffic flow associated with a network device. The method may also include comparing the address within the packet with a stored address, the stored address associated with a route for an alternative traffic path, where the alternative traffic path may be different from a default route of traffic passing through the network device. The method may additionally include, based on the address within the packet matching the stored address, routing the packet along the alternative traffic path instead of the default route of traffic.
