IP Telecom Network Dual-Address Architecture for Secure QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP networks, such as the Internet, lack the necessary security and Quality of Service (QoS) guarantees required for high-security and high-QoS telecommunications services, making it difficult to migrate these services to existing Internet infrastructure, and thus hindering the development of next-generation telecom networks that require both security and flexibility.
Innovation Solution
An IP Telecom Network system is designed with dual-address connectionless data networks, edge gateway devices, and address mapping devices to provide secure and reliable communication, resource management, and support for high-QoS services through a layered architecture, address mapping, and tunnel establishment mechanisms, enabling secure and efficient transmission of packets with header compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing Internet infrastructure is used to carry telecommunication services, then network flexibility and ease of operation are improved, but security and quality of service guarantees deteriorate
Solution Approach 1:
The system divides the network into two distinct segments: an IP network for flexibility and an NCT network for reliability. The IP network handles routing and addressing with its connectionless nature, while the NCT network provides the secure, QoS-guaranteed transmission channel. This segmentation allows each network type to operate in its strength zone without compromising the other.
Solution Approach 2:
The patent introduces edge gateway devices as intermediary components that bridge the IP network and NCT network. These gateways perform protocol conversion, packet encapsulation, and address mapping between the two networks, enabling telecommunication services to leverage both the flexibility of IP networking and the reliability of traditional telecom infrastructure.
2Adaptability or versatility
If traditional telecom networks are transformed to use IP network technology, then network flexibility and adaptability are improved, but security control and service quality management become more difficult
Solution Approach 1:
The system maintains a clear separation between the control plane (in the IP network for flexibility) and the data plane (in the NCT network for controlled transmission). This segmentation allows IP-based adaptability in routing and addressing while preserving traditional telecom-level control and management in the NCT network segment.
Solution Approach 2:
The edge gateway devices are designed with multi-functionality, handling IP packet routing, NCT packet forwarding, address mapping, and security management all in one device. This universality reduces overall system complexity by consolidating multiple functions into standardized gateway components.
3Reliability
If a dual-network architecture is implemented to provide both security and flexibility, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The edge gateway devices serve as intelligent intermediaries that automate the complexity of dual-network management. They handle protocol translation, packet encapsulation/decapsulation, and address mapping automatically, shielding upper-layer applications from the underlying network complexity while maintaining both security and flexibility.
Solution Approach 2:
The system uses packet copying and encapsulation techniques where IP packets are copied and wrapped in NCT packet formats for transmission through the secure network. This copying mechanism allows the same data to traverse different network types with appropriate protocols, maintaining reliability without requiring complete system redesign.
