Solution Overview

Problem

Existing multicast protocols face challenges in efficiently utilizing scarce transmission resources in airborne networks with high terminal node mobility and fail to seamlessly integrate across crypto-partitioned networks, leading to inefficient bandwidth usage and overhead due to redundant data transmissions and lack of uniform support for multicast networking.

Innovation Solution

The implementation of Dynamic Adaptive Hybrid Multicast Routing (DAHMR) and INE-compliant Multicast Signaling Protocol (HC-MSP) enables adaptive multicast routing, optimizing network resource usage and secure, efficient multicast services across red-black boundaries by dynamically adapting to network changes and using multicast gateways to interconnect heterogeneous networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mesh-based protocols are used to reduce packet loss in high mobility networks, then delivery ratio is improved, but bandwidth overhead increases due to redundant paths

Engineering Contradiction:

Improvedelivery ratioVSAvoidbandwidth overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic adaptation between mesh-based and tree-based protocols based on real-time network conditions. The system monitors mobility patterns and delivery requirements, switching from mesh-based routing (providing redundancy for high mobility) to tree-based routing (reducing overhead when mobility is lower), thereby optimizing the trade-off between delivery ratio and bandwidth overhead

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes routing parameters dynamically by adjusting the degree of redundancy and path selection based on network state. When terminal node mobility is high, the system increases redundancy parameters to maintain delivery ratio; when mobility decreases, it reduces redundancy to minimize bandwidth overhead, achieving adaptive optimization of the contradiction

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If tree-based multicast protocols are used to reduce bandwidth overhead, then bandwidth efficiency is improved, but delivery ratio deteriorates in high mobility networks

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent implements dynamic adaptation between mesh-based and tree-based protocols based on real-time network conditions. The system monitors mobility patterns and delivery requirements, switching from tree-based routing (low overhead but vulnerable to mobility) to mesh-based routing (high redundancy for mobility resilience), thereby optimizing the trade-off between bandwidth overhead and delivery ratio

3Loss of energy

If PIM-SM protocols are used to build shared distribution trees, then bandwidth utilization is improved in sparse networks, but adaptability deteriorates when group members are concentrated in specific regions

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidadaptability to member distribution

Core Design Contradiction:

Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic protocol selection that adapts to the spatial distribution of group members. When members are sparse and widely distributed, the system uses PIM-SM shared trees for efficient bandwidth utilization. When members concentrate in specific regions, the system switches to mesh-based or source-specific trees that better adapt to localized distributions, thereby resolving the contradiction between bandwidth efficiency and adaptability

Inventive Principle:

Principle #15Dynamics

4Device complexity

If multicast routing protocols are designed for wired networks, then protocol simplicity is improved, but versatility deteriorates when deployed in wireless mobile networks

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent creates a universal multicast routing system that functions effectively across both wired and wireless mobile networks. By implementing adaptive protocol selection and hybrid routing mechanisms, the system achieves multi-functionality that resolves the contradiction between simplicity and versatility, allowing the same system to optimize performance in different network environments without requiring environment-specific protocol versions

Inventive Principle:

AI summary

This disclosure is directed to techniques for internet group management protocol tunneling. This may be done by electing, by each of a plurality of multicast gateways in a subnet, a designated router in the subnet. The designated router sends internet group management protocol queries to at least one router in the subnet. The designated router further tunnels internet group management protocol reports.
