Locale-Specific Configuration for Distributed Logical Network Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network virtualization technologies like VMware NSX struggle to optimize network performance across different physical contexts, such as data centers, due to uniform connectivity assumptions that do not account for locale-specific properties and limitations.
Innovation Solution
Implementing distributed logical network elements, such as logical switches and routers, that are configured according to the physical context of each locale using locale-specific information to modify behavior, optimize resource usage, and manage next-hop preferences and VM placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform connectivity assumptions are used for distributed logical network elements, then ease of operation and simplified configuration are achieved, but network performance and resource usage efficiency deteriorate due to inability to adapt to locale-specific properties
Solution Approach 1:
The patent introduces locale-specific configuration parameters that allow each physical location to have customized network settings while maintaining the overall distributed logical network structure. This enables optimization for local conditions (such as datacenter-specific requirements) without sacrificing the simplicity of centralized logical network management, thereby resolving the contradiction between ease of operation and network performance.
2Productivity
If locale-specific configurations are implemented for each physical location, then network performance and resource optimization are improved, but device complexity and configuration management burden increase
Solution Approach 1:
The patent employs configurable parameters that can be adjusted based on locale-specific requirements. These parameters allow the distributed logical network elements to adapt their behavior to local conditions without fundamentally changing the architecture. The parameter-based approach enables fine-tuned optimization of resource usage while keeping the underlying system structure manageable and not excessively complex.
3Ease of manufacture
If distributed logical network elements are configured uniformly across all physical nodes, then ease of manufacture and deployment are improved, but adaptability to different physical contexts deteriorates
Solution Approach 1:
The patent introduces dynamic configuration capabilities that allow distributed logical network elements to adapt their behavior based on locale-specific conditions. The system can dynamically adjust parameters such as next-hop preferences, routing policies, and resource allocation based on local context, while maintaining a uniform baseline configuration for ease of deployment. This dynamic adaptability resolves the contradiction between deployment simplicity and locale-specific adaptation.

AI summary
A system for network virtualization in which physical network resources in different physical contexts are configured to implement one or more distributed logical network elements, at least some of the physical network resources implementing the distributed logical network elements configured according the physical context of those network resources. The local configuration of a physical locale is a version of the logical configuration that is modified specifically for the physical locale. Such modification is based on locale identifiers that are assigned to the physical locales. Some systems use locale-specific information to modify next-hop preference. Some system use locally modified configurations to determine the placement of VMs.
