Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network systems face challenges in managing data flows from user equipment in tunneling packet data networks, particularly due to the high cost and operational complexity of passive probing nodes used for monitoring network traffic.
Innovation Solution
A data replication system is introduced, featuring a replication gateway node and a replication control system located in visited and home networks, which creates replication tunnels to replicate data streams, perform analysis, and manage routing, utilizing a replication control plane to isolate, divert, and manage data streams effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If passive probing nodes are used to monitor network traffic, then data flow monitoring capability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent creates a copy of the data stream by establishing a replication tunnel that duplicates traffic flow to a monitoring node. Instead of using complex passive probing nodes that intercept and analyze live traffic, the system creates a simplified copy of the data flow that can be monitored separately, reducing operational complexity while maintaining monitoring capability
Solution Approach 2:
The patent introduces a replication gateway node as an intermediary that sits between the data stream source and destination. This intermediary creates replication tunnels to divert copies of traffic to monitoring nodes, simplifying the monitoring architecture by replacing complex passive probes with a standardized gateway-based approach
2Measurement precision
If passive probing nodes are deployed to monitor network traffic, then data flow analysis capability is improved, but cost increases
Solution Approach 1:
The replication gateway node serves multiple functions: it creates replication tunnels, manages data stream copying, and enables monitoring capabilities. This multi-functional approach replaces the need for multiple specialized passive probing nodes, reducing overall system cost while maintaining data flow analysis capability
Solution Approach 2:
Instead of deploying expensive passive probing nodes throughout the network, the patent uses a single replication gateway to create copies of traffic flows that can be monitored. This copying approach significantly reduces the quantity of monitoring equipment needed, thereby reducing cost
3Adaptability or versatility
If replication tunnels are created for data stream replication, then data management flexibility is improved, but device complexity increases
Solution Approach 1:
The replication tunnel system is designed to be dynamic, allowing tunnels to be created, modified, and terminated based on real-time data management needs. The gateway node can adaptively manage multiple replication tunnels simultaneously, providing flexibility without requiring complex manual configuration for each scenario
Data Source
AI summary
A data replication system of a communication network is disclosed. According to one embodiment, the data replication system includes a replication gateway node and a replication control system located in one or more of a visited network and a home network. The replication gateway node is configured to create a first replication tunnel between a first gateway node and the replication gateway node and a second replication tunnel between the replication gateway node and a second gateway node. The replication gateway node replicates data streams between the first gateway node and the second gateway and delivers the replicated data stream to a management node for further analysis.
