UDP Networking Stability via Error Pattern Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UDP networking faces instability and packet damage issues due to lack of reliability, especially when passing through firewalls and complex network environments, which compromises real-time flexibility and leads to packet blocking.
Innovation Solution
A UDP networking method that adds a specific header area to UDP packets, including sequence data, error detection, and error pattern analysis to ensure stability and prevent packet blocking, by fragmenting data, generating and transmitting UDP packets, determining errors, storing error information, and resetting transmission patterns based on detected errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UDP protocol is used for transmission, then real-time flexibility is maintained, but reliability of transmission data deteriorates
Solution Approach 1:
The patent segments the UDP protocol functionality into two parts: the core UDP protocol maintains its lightweight, fast nature for real-time flexibility, while a separate reliability management module handles error detection, error pattern analysis, and transmission control. This segmentation allows the system to enjoy UDP's speed advantages while adding reliability capabilities through modular components that operate independently but coordinate to ensure data integrity.
2Reliability
If error detection and correction mechanisms are added to UDP, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the receiver analyzes error patterns in received UDP packets and sends feedback information back to the transmitter. The transmitter uses this feedback to adjust transmission strategies, such as modifying transmission intervals or retransmitting problematic data. This feedback loop enables automatic adaptation to network conditions without requiring complex manual configuration or centralized control, thereby improving reliability while keeping the system relatively simple.
3Adaptability or versatility
If fragmentation is applied to large datagrams, then transmission capability is improved, but susceptibility to firewall blocking increases
Solution Approach 1:
The patent applies asymmetry by using non-uniform fragmentation strategies and varying the structure of fragment headers. Instead of using regular, predictable fragmentation patterns that firewalls can easily detect and block, the system employs asymmetric fragment sizes, variable header formats, and randomized sequencing. This makes it difficult for firewalls to identify and block fragmented UDP packets while still enabling transmission of large datagrams through the network.

AI summary
The present invention relates to a UDP networking method which improves the stability against a data damage occurring during a transmission by configuring an additional header area in a UDP transmission packet. The UDP (User Datagram Protocol) networking method for stability improvement may include the steps of: (A) generating, by a transmission terminal, a UDP packet by fragmenting transmission data on a packet basis; (B) transmitting, by the transmission terminal, the generated UDP packet to a reception terminal; (C) determining, by the reception terminal, whether the received UDP packet has an error; (D) storing, by the reception terminal, error information on UDP packet reception and detecting an error pattern; (E) transmitting, by the reception terminal, the detected error pattern to the transmission terminal; and (F) resetting, by the transmission terminal, a packet transmission pattern by reflecting the error pattern. The present invention can ensure stability in processing of repeatedly received data.
