Data Transmission Method for Initial RTT Bandwidth Utilization

1Reliability

If congestion control algorithms limit data transmission rate, then network congestion is prevented, but network bandwidth utilization decreases and throughput is reduced

Engineering Contradiction:

Improvecongestion preventionVSAvoidnetwork bandwidth utilization

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by sending a large quantity of data packets in the initial RTT before congestion can occur. The transmit end proactively utilizes free network bandwidth by sending multiple data packets simultaneously in the first round-trip time, rather than waiting for acknowledgments between packets. This preliminary data transmission fills the network bandwidth before congestion control mechanisms would otherwise limit the rate.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics by dynamically adjusting the data transmission strategy based on whether it is the initial RTT or subsequent RTTs. In the initial RTT, the system transmits a large quantity of packets at high rate, while in subsequent RTTs, it transitions to traditional congestion control. This dynamic adjustment allows the system to maximize bandwidth utilization when the network is known to be free, while maintaining reliability when congestion risk exists.

Inventive Principle:

Principle #15Dynamics

2Reliability

If traditional congestion control is used in initial RTT, then congestion is avoided, but data transmission delay increases and throughput decreases

Engineering Contradiction:

Improvecongestion avoidanceVSAvoiddata transmission delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by sending a large quantity of data packets in the initial RTT before congestion can occur. The transmit end proactively utilizes free network bandwidth by sending multiple data packets simultaneously in the first round-trip time, rather than waiting for acknowledgments between packets. This preliminary data transmission fills the network bandwidth before congestion control mechanisms would otherwise limit the rate.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies skipping by rushing through the initial RTT with a high rate of data packet transmission, skipping the cautious slow-start phase of traditional congestion control. By sending a large quantity of packets immediately in the initial RTT, the system rushes to utilize available bandwidth before network conditions change, thereby reducing transmission delay.

Inventive Principle:

Principle #21Skipping (Rushing through)

3Productivity

If data packets are sent at high rate in initial RTT, then bandwidth utilization increases, but network congestion probability increases
