Solution Overview

Problem

Current MoCA home networks experience high reservation request overhead, which linearly increases with the number of nodes, leading to increased access latency and reduced efficiency in data transmission.

Innovation Solution

Implementing a method that dynamically optimizes reservation requests by monitoring ingress traffic patterns, predicting future transmission needs, and aggregating data packets for transmission during designated future opportunities, thereby reducing media access latency and reservation request overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional reservation request methods are used in MoCA networks, then each node can transmit data with guaranteed quality of service, but the reservation request overhead linearly increases with the number of nodes

Engineering Contradiction:
Improvequality of serviceVSAvoidreservation request overhead
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple reservation requests into a single aggregated reservation request that represents multiple nodes' transmission needs. Instead of each node sending individual reservation requests, the system merges these requests and processes them collectively, reducing the total number of reservation requests from O(n) to O(1) where n is the number of nodes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal reservation request mechanism that can represent and handle transmission requests from multiple different nodes simultaneously. A single reservation request structure is designed to accommodate aggregated data from multiple sources, making the reservation system multi-functional and applicable to various node combinations without requiring node-specific request formats.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If individual reservation requests are sent by each node, then transmission requirements can be accurately tracked, but access latency increases due to processing overhead

Engineering Contradiction:
Improvetransmission requirements trackingVSAvoidaccess latency
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges multiple individual transmission requirement tracking operations into a single aggregated tracking process. By combining the reservation requests and processing them together, the system reduces the number of separate tracking operations while maintaining the ability to monitor and manage transmission requirements for all participating nodes through the aggregated request structure.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If reservation requests are processed for every node individually, then network control precision is maintained, but network efficiency decreases

Engineering Contradiction:
Improvenetwork control precisionVSAvoidnetwork efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent merges the processing of multiple individual reservation requests into a single consolidated processing operation. The network controller receives and processes aggregated reservation requests that represent multiple nodes' needs, reducing the processing load from O(n) individual operations to O(1) consolidated operations while maintaining precise control over each node's allocated resources through the aggregated request structure.

Inventive Principle:
Principle #5Merging (Combining)
