Solution Overview
Problem
Current technologies, such as PCP, fail to efficiently and effectively discover network address allocations and translations in complex wireless communication systems, particularly for wireless communication devices with multiple IP paths and NAT layers.
Innovation Solution
A communication network system that enables wireless communication devices to discover and report IP address allocation and translation data through a process involving gateway systems, DNS servers, and NAT systems, using protocols like DHCP and NAT64, to generate content delivery footprint data that includes internal and external IP address mappings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If PCP is used to discover NAT translations, then IPv6 prefix translation can be identified, but wireless communication devices cannot efficiently discover network address allocations and translations in complex IP systems with multiple NAT layers and parallel IP paths
Solution Approach 1:
The patent extends PCP functionality to work universally across multiple IP versions and NAT layers. The system implements a discovery protocol that can identify NAT translations in IPv4, IPv6, and dual-stack environments, making it applicable to complex wireless communication systems with mixed protocols and multiple NAT layers simultaneously.
Solution Approach 2:
The patent adds a new dimension to PCP by introducing a discovery mode that operates independently from the traditional port control function. This enables the system to discover NAT translations across multiple IP paths and NAT layers without interfering with normal data traffic, effectively adding a discovery dimension to the existing PCP framework.
2Adaptability or versatility
If multiple NAT layers and parallel IP paths are implemented, then connectivity and compatibility services are enhanced, but the complexity of discovering and managing IP address translations increases
Solution Approach 1:
The patent implements self-service by enabling wireless communication devices to automatically discover their own NAT translations and IP address allocations through the enhanced PCP protocol. Devices can query for their assigned addresses and translations without requiring manual configuration or complex management from network administrators, reducing operational complexity despite the presence of multiple NAT layers.
Solution Approach 2:
The system incorporates feedback mechanisms where the discovery protocol continuously monitors and reports on NAT translation status. This feedback enables dynamic adaptation to changing network conditions, allowing devices to maintain accurate routing information even as NAT layers are added or modified in complex wireless communication environments.
Data Source
AI summary
A wireless user device is served by a wireless network that performs Network Address Translation (NAT). The wireless user device exchanges user data using a device IP address and a network gateway exchanges the user data with external systems using an external IP address. The user device receives network information that indicates a network server and queries the network server for IP address translation data. The user device receives the IP address translation data from the network server that indicates that the external IP address is associated with the device IP address for the wireless user device. The user device transfers content delivery footprint data to a content delivery network. The content delivery footprint data indicates media content stored on the user device and indicates that the external IP address is associated with the device IP address for the user device.
