Integrated Traffic Generator for IPSEC Tunnel Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network traffic analysis tools and traffic generation systems operate as separate entities, lacking integrated capabilities for simulating secure IPSEC tunnels and comprehensive network testing, which hinders effective validation of VPN performance and security in IP networks.
Innovation Solution
A system comprising a traffic generator and receiver, coupled with a gateway, simulates hosts and gateways to create and process traffic, establishing IPSEC tunnels for secure data transmission, allowing for the validation of tunnel capacity, setup rates, encryption/decryption latency, throughput, and loss, and providing real-time diagnostics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate network traffic analysis tools and traffic generation systems are used, then device complexity is reduced, but validation comprehensiveness deteriorates
Solution Approach 1:
The patent combines separate network traffic analysis tools and traffic generation systems into a single integrated system. The system includes both a traffic generator component and a network analyzer component that work together within one device, enabling comprehensive network validation while maintaining manageable complexity through unified architecture.
Solution Approach 2:
The integrated system performs multiple functions simultaneously: it generates network traffic, analyzes network performance, validates VPN tunnel capacity, measures encryption latency, and monitors network security. This multi-functional capability allows a single system to replace multiple separate tools while enhancing overall validation comprehensiveness.
2Measurement precision
If comprehensive VPN validation is performed, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system performs continuous network traffic generation and analysis without interruption. The traffic generator continuously sends packets through VPN tunnels while the network analyzer simultaneously monitors and measures performance metrics, enabling comprehensive validation to be completed efficiently without repeated setup and teardown cycles.
Solution Approach 2:
The system pre-configures multiple VPN tunnel scenarios and test parameters before execution. By preparing test configurations, traffic patterns, and measurement criteria in advance, the system can perform comprehensive validation more quickly when actually executed, reducing the time loss associated with on-the-fly configuration during testing.
Data Source
AI summary
There is disclosed methods and apparatus for generation of processed traffic. An environment may include a traffic generator, a network, a gateway and a traffic receiver. The abilities of the gateway may be tested by generating traffic from the traffic generator and transmitting it to the traffic receiver via the network and the gateway. Time constraints of processor-intensive processing may be avoided by holding or looping back traffic from the traffic generator so that the traffic may be transmitted as needed for a test.
