Dynamic Congestion Window Initialization via Historical Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard networking protocols, such as TCP, suffer from inefficiencies in fixed or recurring network environments due to their slow-start mechanisms, which can be optimized by dynamically initializing the congestion window based on previous connection data, without compromising interoperability.
Innovation Solution
Implementing an initialization agent that monitors and tracks congestion windows of recurring connections to dynamically initialize the congestion window of new connections with values derived from previous instances, thereby bypassing the TCP slow-start phase and improving network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If standard TCP slow-start mechanism is used to initialize congestion window, then interoperability with standard protocols is ensured, but network throughput is reduced and transmission time is increased
Solution Approach 1:
The system performs preliminary actions by monitoring and tracking congestion window values from previous connections between the same endpoint pairs. Before a new connection is established, the initialization agent retrieves the previously observed congestion window value and configures it for the upcoming connection, thereby avoiding the need for slow-start mechanism and enabling immediate high-throughput data transmission.
Solution Approach 2:
The system creates a copy of the congestion window configuration from a previous connection instance and applies it to the new connection. The initialization agent copies the tracked congestion window value from historical data and uses it to initialize the new connection's congestion control parameters, replicating the successful configuration from prior connections.
2Productivity
If dynamic congestion window initialization is implemented to improve network performance, then throughput is enhanced, but protocol complexity increases
Solution Approach 1:
The initialization agent acts as an intermediary component that sits between the standard TCP stack and the network connection. It monitors congestion window values, tracks them in a database, and automatically configures new connections without requiring changes to the core TCP protocol implementation. This intermediary approach enables performance optimization while maintaining compatibility with standard TCP protocols.
Solution Approach 2:
The system implements self-service by automatically monitoring, tracking, and configuring congestion window values without manual intervention. The initialization agent autonomously retrieves historical congestion window data, matches it with new connections based on endpoint pairs, and applies the appropriate configuration, eliminating the need for manual protocol tuning or complex configuration management.
3Adaptability or versatility
If TCP slow-start mechanism is used to ensure protocol standardization, then interoperability is maintained, but the number of outstanding packets that can be sent initially is limited
Solution Approach 1:
The system changes the congestion window parameter from its standard TCP initial value to a dynamically determined value based on historical connection data. By modifying this key parameter while maintaining the overall TCP protocol structure, the system enables a larger number of outstanding packets to be sent initially, thereby improving throughput while preserving interoperability through standard protocol mechanisms.

AI summary
Some embodiments increase throughput across a connection between a host and a client by initializing the congestion window for that connection dynamically using a previously settled value from a prior instance of the connection established between the same or similar endpoints. An initialization agent tracks congestion window values for previously established connections between a host and various clients. For the tracked congestion window values of each monitored connection, the initialization agent stores an address identifying the client endpoint. When establishing a new connection, the initialization agent determines if the new connection is a recurring connection. A new connection is recurring when the new connection client address is similar or related to an address identified for a previous monitored connection. For a recurring connection, the initialization agent initializes the new connection congestion window using a value derived from the tracked congestion window values of the recurring connection.
