Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite networks face inefficiencies due to high bandwidth costs and latency, exacerbated by traditional routing protocols that are not optimized for peer-to-peer applications, leading to suboptimal routing and increased overhead in bandwidth usage.
Innovation Solution
A mesh connectivity approach in satellite networks with a central route server that collects and distributes routing information, allowing terminals to redirect packets based on local route tables, reducing overhead and improving protocol efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional routing protocols are used in satellite networks, then routing functionality is provided, but bandwidth overhead increases and protocol efficiency decreases
Solution Approach 1:
The routing system is segmented into a centralized route server that collects routing information and multiple route clients that receive distributed routing updates. This segmentation allows routing information to be aggregated at one point and efficiently distributed, reducing redundant routing traffic across the satellite network while maintaining protocol functionality.
2Ease of operation
If hub and spoke architecture is used, then network connectivity is provided, but delay increases for peer-to-peer applications
Solution Approach 1:
The network architecture transitions from a two-dimensional hub-and-spoke model to a three-dimensional mesh topology where nodes can communicate directly with multiple neighbors. This dimensional change enables peer-to-peer routing paths that bypass the central hub, reducing delay for applications that require direct node-to-node communication while preserving the underlying hub-and-spoke infrastructure for connectivity.
3Adaptability or versatility
If mesh connectivity is implemented, then peer-to-peer routing is enabled, but network complexity increases
Solution Approach 1:
A centralized route server acts as an intermediary that manages the complexity of mesh connectivity. The route server collects routing information from all nodes, computes optimal paths, and distributes routing updates to route clients. This intermediary approach enables peer-to-peer routing capabilities while centralizing the computational complexity, making the mesh network manageable without requiring each node to independently handle complex routing calculations.

AI summary
An approach for routing over a radio network is provided. A terminal receives a packet over the radio network, which supports meshed connectivity, wherein the packet is destined for a destination host. The terminal determines whether the destination host is reachable by a communication interface based upon a route table, and selectively redirects the packet over the radio network according to the route table. A route server is provided to collect routes from the terminal as well as other terminals within the radio network. The route server then disseminates the collect routes to the terminals for updating of their respective route tables. The present invention has particular applicability to a fully meshed satellite network.
