Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional networks face scalability issues and inefficiencies in handling large network growth and node mobility, preventing nodes from concurrently accessing services from multiple distinct service domains.
Innovation Solution
A network framework that allows nodes to be members of multiple social networks by maintaining a selected mesh of connections and using virtual nodes with services engines, communications engines, and transport engines to facilitate concurrent access to services across different enterprises, enabling efficient communication and service utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hierarchical networks are used, then network structure is simple and easy to manage, but scalability is poor and cannot accommodate large network growth
Solution Approach 1:
The patent segments the network into service domains (SDs) and service instances (SIs), allowing independent scaling of each domain. Each SD can grow independently without affecting the entire network, resolving the scalability issue while maintaining manageable structure through modular organization.
Solution Approach 2:
The patent introduces service discovery mechanisms and location services as intermediaries that enable nodes to automatically discover and connect to services without manual configuration. This mediation layer simplifies the complexity of service discovery and network convergence.
2Reliability
If nodes tunnel back to their home enterprise network, then hierarchy is maintained and security is improved, but communication efficiency deteriorates when nodes are physically close
Solution Approach 1:
The patent implements dynamic routing where nodes can dynamically choose between tunneling to home network or using local service domains based on real-time conditions. When nodes are physically close and local services are available, direct communication is preferred for efficiency; when security requires it, tunneling is used. This dynamic adaptation resolves the contradiction between security and efficiency.
3Adaptability or versatility
If nodes can join multiple enterprise networks simultaneously, then service accessibility is improved, but network management complexity increases
Solution Approach 1:
The patent creates a universal service domain framework where nodes can join multiple SDs and SIs simultaneously through standardized interfaces. The service discovery mechanism provides universal access to services across different domains without requiring domain-specific management protocols, enabling multi-network membership while simplifying management through uniform procedures.
4Reliability
If full mesh connections are established between all nodes, then communication reliability is improved, but network complexity and resource consumption increase
Solution Approach 1:
The patent merges multiple connection paths through service domains and instances, allowing nodes to access services through shared infrastructure rather than dedicated point-to-point connections. This consolidation maintains communication reliability through multiple logical paths while reducing physical connection complexity and resource consumption.
