Adaptive Packet Spacing for Peer-to-Peer Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peer-to-peer networks experience congestion issues due to the lack of a central server, leading to packet loss and reduced throughput, which existing methods struggle to effectively manage.
Innovation Solution
Nodes in the network detect congestion and non-congestion events, adjusting the spacing of connectionless protocol packets to manage traffic, increasing spacing during congestion and decreasing it during non-congestion to maximize throughput and minimize packet loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If nodes continuously send packets in peer-to-peer network, then throughput is maximized, but packet loss increases due to congestion
Solution Approach 1:
The patent applies dynamics by making packet spacing adaptive rather than fixed. Nodes dynamically adjust the time interval between packets based on real-time network conditions (congestion events), transitioning from continuous sending during non-congestion to spaced sending during congestion. This dynamic adjustment resolves the contradiction by allowing high throughput when possible while preventing packet loss when needed.
Solution Approach 2:
The patent implements feedback mechanisms where nodes monitor network conditions (detecting congestion events) and use this information to adjust packet spacing. The feedback loop consists of: detecting congestion events, adjusting packet spacing accordingly, and continuing to monitor network conditions. This feedback mechanism enables nodes to self-regulate traffic, resolving the throughput-reliability contradiction through continuous adaptation.
2Reliability
If nodes increase packet spacing to reduce congestion, then packet loss decreases, but throughput is reduced
Solution Approach 1:
The patent resolves this contradiction through dynamic packet spacing that adapts to network conditions. During non-congestion periods, nodes use small packet spacing to maximize throughput. When congestion is detected, nodes automatically increase spacing to reduce packet loss. This dynamic behavior ensures that throughput is maximized when possible while reliability is protected when needed, rather than using a fixed spacing that would permanently sacrifice one for the other.
Solution Approach 2:
The patent changes the parameter of packet spacing based on network conditions. Instead of using a constant spacing value, the system varies the spacing parameter in response to detected congestion events. This parameter change allows the system to optimize for throughput during good conditions and optimize for reliability during congestion, resolving the contradiction through conditional parameter adjustment.
3Ease of operation
If nodes continuously monitor network conditions to adjust packet spacing, then traffic management improves, but processing overhead increases
Solution Approach 1:
The patent applies self-service by enabling nodes to autonomously monitor their own network conditions and adjust their own packet spacing without external intervention. Each node independently detects congestion events and self-regulates traffic based on local conditions. This self-service approach simplifies traffic management while avoiding the processing overhead of centralized control, as nodes only perform basic monitoring and adjustment operations.
Solution Approach 2:
The patent uses feedback mechanisms where nodes monitor network conditions and adjust packet spacing based on detected events. The feedback loop is simple: detect congestion, adjust spacing, continue monitoring. This lightweight feedback approach enables effective traffic management without requiring complex processing, as nodes only need to implement basic event detection and spacing adjustment logic.

AI summary
In a peer-to-peer network, one or more congestion events are defined that imply congestion on the network. In addition, one or more non-congestion events are defined that imply a lack of congestion on the network. When a node detects the occurrence of one or more of the defined congestion events, the node increases the spacing of connectionless protocol (e.g., UDP) packets that are sent by the node. When a node detects the occurrence of one or more of the defined non-congestion events, the node decreases the spacing of connectionless protocol packets that are sent by the node.
