Proxy Gateway Batching for AMI Network Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The registration process in Advanced Metering Infrastructure (AMI) networks consumes a large portion of bandwidth, causing traffic congestion due to individual node registration, which is inefficient in large networks with thousands or millions of nodes.
Innovation Solution
Implementing proxy gateways that collect and relay registration information from nodes in batch mode, acting as intermediaries between new nodes and network gateways or Access Points (APs), reducing communication traffic and congestion by segmenting the network into sub-networks with designated proxy gateway nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual node registration is implemented in large AMI networks, then each node can establish communication and register its presence, but network bandwidth is consumed excessively and traffic congestion occurs
Solution Approach 1:
The patent introduces a proxy gateway as an intermediary between nodes and the central system. The proxy gateway collects registration requests from multiple nodes and forwards them in batch mode, reducing individual node communications and overall bandwidth consumption while maintaining reliable registration for all nodes.
Solution Approach 2:
The patent merges multiple individual registration requests into a single batch request. By combining registration data from multiple nodes into one consolidated communication event, the system reduces total bandwidth usage and eliminates the additive bandwidth consumption of individual registrations.
2Loss of information
If individual node registration is performed, then complete node information is captured, but network traffic congestion increases due to the large number of registration requests
Solution Approach 1:
The patent combines multiple node registration requests into a single batch request processed by the proxy gateway. This merging approach maintains complete node information for all registering nodes while significantly reducing network traffic volume and improving overall network throughput by eliminating redundant communication overhead.
3Loss of energy
If batch mode registration is implemented, then network bandwidth is optimized and traffic congestion is reduced, but the complexity of the registration system increases
Solution Approach 1:
The patent introduces a proxy gateway as an intermediary layer that implements batch processing logic. While this adds a system component, it centralizes the complexity in a dedicated gateway rather than requiring complex logic in each node or the central system, making the overall architecture more manageable and scalable.
4Productivity
If proxy gateways are introduced to batch registration requests, then bandwidth usage is reduced and traffic congestion decreases, but the device complexity of the network architecture increases
Solution Approach 1:
The patent introduces proxy gateways as intermediary devices that consolidate registration traffic. While this adds architectural layers, it improves network efficiency by reducing overall traffic volume and congestion. The complexity is localized to the gateway layer, which can be managed independently, allowing the rest of the network to operate more efficiently.
Data Source
AI summary
A system and method is presented for broadcasting from a utility node a request for network routing information, receiving at the utility node routing information from neighboring utility nodes in response to the broadcast request, and registering the utility node with an access point that provides ingress and egress to and from the network. A node is selected to function as a proxy gateway for one or more other nodes in the network. A new utility node becomes connected to one or more utility networks by registering with the proxy gateway. The proxy gateway transmits registration requests and registration information from each node to a back office server and/or a Domain Name Server via an access point for which the proxy gateway functions as its proxy.
