DNS-Based Registration for Utility Network Address Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility network management systems face challenges in large-scale networked commodity metering deployments and dynamic network infrastructure, where earlier standards like ANSI C12.22 and DA protocols are not designed to handle complex address resolution and registration in large-scale, dynamic environments.
Innovation Solution
Implementing DNS-based registration support and address resolution services using well-known IP-based application protocols like Domain Name Servers (DNS) or directory server technology, such as LDAP, to facilitate easier registration and address resolution for devices communicating at the application layer, enabling multi-homing and increased robustness in utility networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DNS-based registration support and address resolution services are implemented, then address resolution efficiency and network robustness are improved, but device complexity and infrastructure requirements increase
Solution Approach 1:
The patent introduces DNS servers and LDAP directory servers as intermediary components that mediate between devices and the network infrastructure. These intermediaries handle address resolution and registration functions, allowing devices to communicate without direct complex infrastructure support. The DNS server resolves domain names to IP addresses, while LDAP servers provide directory services for device registration and authentication, thereby improving network robustness while distributing complexity to specialized infrastructure components.
2Adaptability or versatility
If multi-protocol support is implemented for comprehensive network services, then adaptability and versatility are improved, but device complexity and protocol management overhead increase
Solution Approach 1:
The patent implements universal infrastructure components (DNS servers, LDAP servers, relay nodes) that can serve multiple protocols and device types simultaneously. These universal components provide common services like address resolution, registration, and authentication across different communication protocols (GPRS, CDMA 1X RTT, and other cellular technologies). By using universal infrastructure, the system achieves multi-protocol support without requiring each device to manage protocol-specific complexity individually, as the infrastructure handles protocol translation and routing.
Solution Approach 2:
Relay nodes act as intermediaries between devices using different protocols and the core network infrastructure. These relay nodes translate between various cellular protocols and the standardized DNS/LDAP infrastructure, enabling multi-protocol devices to access network services without directly managing protocol complexity. The relay node receives messages from devices using different protocols, resolves addresses through DNS/LDAP, and forwards messages appropriately, thereby reducing protocol management overhead at the device level.

AI summary
The functionality of communications standards and protocols that are application-layer specific are overlaid on an IP-based infrastructure, by employing an IP DNS server as the registration host for IP and other communications standards based and protocol based communications. Communication can occur at either the IP layer or the communications standards or protocol application layer. At the IP layer, a host application can interrogate network nodes. To extend this service to other communications standards or protocol communications, device registration and resolve services are implemented on the DNS server. Similar to the manner in which an IP-based service uses a native, IP-based DNS resolve request, a host can utilize a resolution request against the communications standards and protocol-enabled DNS server for standards and protocol application-layer interrogation of endpoints.
