Dynamic Policy-Based Network Path Routing for Traffic Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks require pre-set network paths for inspections and controls, making it difficult to dynamically manage network traffic and resource distribution, especially during changes in network switches and routers, which limits the flexibility and efficiency of network application appliances in handling service sessions.
Innovation Solution
Implementing a policy-based network path system that allows data packets to be routed dynamically based on packet information and processing criteria, using policy enforcing points and databases to determine and select optimal network paths for inspections and controls, enabling flexible deployment of network application appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If network paths are pre-set using traditional routing protocols, then network stability and predictability are improved, but network flexibility and adaptability to changes in switches and routers deteriorate
Solution Approach 1:
The patent implements dynamic network path selection by enabling network application appliances to autonomously determine and switch between different network paths based on real-time conditions, transforming the static pre-set path model into a dynamic adaptive system that responds to network changes without requiring manual reconfiguration
Solution Approach 2:
The patent introduces policy enforcing points as intermediary components that mediate between the network application appliances and the network infrastructure, allowing appliances to request and receive alternative network paths without directly modifying routing protocols or network switch configurations
2Reliability
If network application appliances are deployed along pre-set network paths, then inspection and control functions are ensured, but network engineering complexity and deployment difficulty increase
Solution Approach 1:
The patent enables network application appliances to self-determine their optimal network paths and autonomously select alternative routes when needed, eliminating the need for network administrators to manually engineer and plan paths for each appliance deployment, thereby reducing network engineering complexity while maintaining functional reliability
Solution Approach 2:
The patent establishes policy enforcing points in advance that are configured with policies for selecting network paths, allowing network application appliances to automatically utilize these pre-configured paths without requiring real-time network engineering or complex deployment planning
3Productivity
If additional network application appliances are deployed to handle increased traffic, then processing capacity is improved, but network path planning complexity and resource distribution challenges worsen
Solution Approach 1:
The patent enables each network application appliance to independently and dynamically determine its own network path based on real-time traffic conditions and appliance capabilities, allowing multiple appliances to be deployed without requiring complex centralized path planning or load distribution strategies, thereby scaling processing capacity while maintaining path determination simplicity
Data Source
AI summary
Provided are methods and systems for processing data packets in a data network using a policy-based network path. The method may commence with receiving the data packet associated with a service session from a client. The method may continue with determining data packet information associated with the data packet. The method may further include determining the policy-based network path for the data packet based on the data packet information and one or more packet processing criteria. The method may continue with routing, based on the determination of the policy-based network path, the data packet along the policy-based network path.
