Dual-Channel Data Transfer Balancing TCP Reliability and UDP Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer technologies face undesirable latency issues due to increased network distances and data sizes, which are exacerbated by the use of protocols like TCP, and hardware-based solutions are not always feasible.
Innovation Solution
Implementing a protocol module that utilizes a control channel with a different protocol (e.g., TCP) for control information and a transmission channel with a less latency-prone protocol (e.g., UDP) to adjust and prioritize data transmission, ensuring reliable and efficient data transfer without requiring hardware modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP protocol is used for data transmission, then reliability is improved, but latency increases
Solution Approach 1:
The patent segments data transmission into two separate channels: a control channel using TCP protocol for reliability-critical control information, and a data channel using UDP protocol for latency-sensitive data transmission. This segmentation allows each channel to use the most appropriate protocol for its specific function, resolving the contradiction between reliability and latency.
Solution Approach 2:
The patent introduces a protocol module as an intermediary layer between the application and the network. This module manages two separate channels (control and data channels), mediating between the reliability requirements of TCP and the latency requirements of UDP, allowing the system to leverage both protocols' strengths without requiring hardware modifications.
2Adaptability or versatility
If data transmission distance increases, then network coverage is improved, but latency increases
Solution Approach 1:
The patent implements dynamic protocol selection and channel management within the protocol module. The system can dynamically adjust which channel (control or data) is used for specific transmissions based on network conditions, distance, and data type, allowing optimal performance across varying network distances without hardware changes.
3Productivity
If existing applications are modified to reduce latency, then transfer speed is improved, but system complexity increases
Solution Approach 1:
The protocol module serves as an intermediary that existing applications can use without modification. By placing the dual-channel protocol logic in this intermediate layer rather than requiring changes to applications themselves, the system achieves improved transfer speed while minimizing the increase in system complexity.
Solution Approach 2:
The protocol module is designed as a universal component that can serve multiple functions: it handles both control information and data transmission, supports both TCP and UDP protocols, and works with existing applications without requiring them to be modified. This multi-functionality reduces overall system complexity while improving productivity.

AI summary
Embodiments of systems and methods for data transfer are presented herein. Specifically, embodiments of such a data transfer methodology may utilize one or more transmission channels for the transmission of the data to be transferred. In addition, a control channel in a different protocol than the transmission channels may be utilized to transmit control information between the sender and recipient. The rate at which data is sent on the transmission channels may be adjusted or the transmission of data on the transmission channel prioritized.
