Virtual Network Map Updates via Shadow System Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-path routing techniques in network communications, such as Hash-Based Routing and Smart Path Assignment in Networks, face challenges in dynamically adapting to changing network traffic conditions, leading to suboptimal VLAN configurations that fail to efficiently distribute traffic over time.
Innovation Solution
A shadow system simulates network traffic to generate probabilistic routing tables and VLAN maps, which are periodically updated based on flow rate statistics, allowing for dynamic adaptation of VLAN sets by creating new paths or reconfiguring existing VLANs to optimize route selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-path routing techniques are used to provide alternative paths through the network, then fault tolerance and bandwidth are improved, but the system fails to dynamically adapt to changing network traffic conditions
Solution Approach 1:
The patent implements dynamic adaptation by continuously monitoring network traffic conditions and updating VLAN configurations in real-time. The system transitions from static routing to dynamic routing where paths are automatically adjusted based on current network state, enabling the system to adapt to changing traffic patterns while maintaining fault tolerance.
Solution Approach 2:
The patent employs feedback mechanisms where network traffic statistics are collected and used to update VLAN maps and routing decisions. This closed-loop feedback system allows the network to learn from actual traffic patterns and adjust configurations accordingly, resolving the contradiction between maintaining reliability and adapting to changing conditions.
2Productivity
If VLAN configurations are updated frequently to reflect changing conditions, then traffic distribution efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the network system to automatically update its own VLAN configurations based on monitored traffic conditions. Rather than requiring manual intervention or complex centralized management, the system autonomously adjusts routing paths and VLAN assignments, improving traffic distribution efficiency while keeping management complexity manageable through automation.
Solution Approach 2:
The patent changes key parameters in VLAN configurations dynamically based on network conditions. By adjusting parameters such as traffic weights, path selections, and VLAN assignments according to real-time statistics, the system optimizes traffic distribution without requiring complete reconfiguration, thus improving productivity while controlling complexity through incremental parameter adjustments.
Data Source
AI summary
A switch determines a path, not included in a first set of virtual networks associated with the switch. It is determined if the path can be added to an existing virtual network in the first set of virtual networks. If the path cannot be added, a new virtual network is created to include the path.
