Polymorphic Network Control for Mobile Terminal Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing IP-based Internet architecture is not well-suited for mobile devices, leading to reliability and continuity issues with mobile terminal access due to its reliance on static network addresses and fixed communication paths, which is inadequate for the increasing number of mobile devices and data traffic.
Innovation Solution
A polymorphic network control system and method that separates identifiers from locators, utilizing a global identity resolution service, a polymorphic SDN controller, and hybrid routing based on identity and address information to support mobile terminal access, enabling flexible and reliable data transmission across changing network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If IP-based Internet architecture with static network addresses is used, then network management is simplified, but mobile terminal access reliability and continuity deteriorate
Solution Approach 1:
The patent segments the network address into two independent components: identity information (permanent identifier) and location information (temporary address). This segmentation allows the identity to remain constant while location changes, resolving the contradiction between simplified management and mobile reliability.
Solution Approach 2:
The patent introduces a polymorphic SDN controller as an intermediary between the terminal and the network infrastructure. This controller dynamically manages the mapping between identity and location, maintaining connection continuity during mobile access without requiring complex terminal-side modifications.
2Device complexity
If static network addresses and fixed communication paths are used, then network routing is simplified, but mobile device support deteriorates
Solution Approach 1:
The patent implements dynamic routing by separating fixed identity information from variable location information. The routing system can dynamically update location mappings in the polymorphic SDN controller while maintaining the same identity-based routing logic, enabling mobile device support without increasing terminal complexity.
Solution Approach 2:
The patent extracts location information from the traditional IP address and handles it separately through the polymorphic SDN controller. This extraction allows the core routing mechanism to remain simple and identity-based, while mobile-specific location management is handled by the intermediary controller.
3Reliability
If network address reassignment is required upon connection change, then network security is improved, but communication continuity deteriorates
Solution Approach 1:
The patent performs preliminary binding of identity to location information in the polymorphic SDN controller before communication occurs. When mobile devices change connections, the controller proactively updates the mapping before disconnection happens, maintaining communication continuity while the identity remains securely bound to the device.
Solution Approach 2:
The patent maintains continuous communication by keeping the identity-based connection active while allowing location information to change. The polymorphic SDN controller ensures seamless updates to location mappings, allowing communication to continue without interruption during network transitions.
Data Source
AI summary
A polymorphic network control system and a polymorphic network control system method supporting terminal mobile access. A network architecture is redesigned based on the idea of separation of an identifier from a locator. In this network mode, the three-layer protocol is no longer a traditional IP message, but a message carrying a locator and an identifier. The polymorphic SDN network controller is responsible for forwarding the data packet to a destination corresponding to a destination locator. When the network location of a mobile device is changed, the transmission connection established based on the identifier will suspend communication due to the disconnection of the physical link. When the mobile device is re-accessed and a new forwarding path is established, the transmission connection can recover communication.
