Bandwidth Adaptive N-to-N Communication Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed computing environments, existing communication mechanisms, such as 1-to-N multicast channels, require N^2 channel subscriptions and O(N^2) state maintenance, leading to scalability issues for large numbers of computing devices.
Innovation Solution
Implementing a single shared channel where each computing device subscribes, allowing each device to publish its state as packets, and using bandwidth adaptive methods to transmit data, reducing subscriptions to N and state maintenance to O(N), enabling efficient communication across devices with varying connection speeds.

Engineering Contradiction Analysis
1Adaptability or versatility
If 1-to-N multicast channels are used for direct communication between computing devices, then communication capability is provided, but system complexity and state maintenance requirements increase quadratically with the number of devices
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes the maintenance of participant state information. Instead of each participant maintaining O(N) subscriptions and state for every other participant, the server maintains a centralized state store that all participants access. This reduces the distributed state maintenance complexity from O(N^2) across all participants to O(N) centralized at the server, while preserving full communication capability between any pair of participants through the mediating server.
2Reliability
If each computing device subscribes to every other device's channel, then direct communication is enabled, but the number of subscriptions required increases quadratically
Solution Approach 1:
The patent merges N separate 1-to-N multicast channels into a single shared communication channel. Instead of each participant creating and maintaining subscriptions to N individual channels (resulting in N^2 total subscriptions), all participants subscribe to one unified channel. The server manages participant state on this single channel, reducing the total subscription count from O(N^2) to O(N) while maintaining the ability for any participant to communicate with any other participant through the shared channel.
3Adaptability or versatility
If bandwidth adaptive transmission is implemented, then devices with varying connection speeds can participate, but data transmission complexity increases
Solution Approach 1:
The patent implements dynamic bandwidth adaptation by making the server selectively transmit participant state data based on real-time network conditions and recipient capabilities. The server monitors transmission success and adjusts its behavior dynamically - retransmitting data to participants with slower connections who may have missed updates, while avoiding redundant transmissions to participants with fast, reliable connections. This dynamic approach allows the system to adapt to varying bandwidth conditions without requiring complex client-side bandwidth management logic at each participant device.

AI summary
Methods and systems for bandwidth adaptive computing device to computing device communication are described. Bandwidth adaptive communication includes receiving a communication from a first participant, storing the payload data of the communication in a channel memory element associated with the first participant, and transmitting the payload data to a second participant.
