Data Transmission Unit Subdivision for Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transport networks experience packet loss due to congestion and limitations, leading to high costs for businesses seeking high performance and low latency across geographically remote locations, with existing solutions either requiring extensive retooling or being protocol-specific.
Innovation Solution
The system subdivides data transmission units from a source network into smaller units with additional encoded units for transmission through a transport network, allowing for recreation of original units even if some are lost, and requests re-transmission if insufficient units are received, using a server architecture with segmentation and reassembly modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high performance transport networks are leased to ensure good application performance and minimize packet loss, then data transmission reliability is improved, but network cost increases
Solution Approach 1:
The patent segments data transmission units into multiple smaller packets for transmission. This allows the system to use lower-cost transport networks while maintaining reliability through segmentation and redundancy, as individual packet losses can be recovered without requiring expensive high-performance networks
Solution Approach 2:
The patent performs preliminary encoding and adds redundant data to packets before transmission. This preliminary action enables the system to recover from packet losses during transmission without requiring expensive retransmission protocols or high-performance networks, thereby reducing network costs while maintaining reliability
2Reliability
If custom protocols are used at end networks to be less affected by data loss and latency, then application performance is improved, but system complexity and retooling requirements increase
Solution Approach 1:
The patent introduces an intermediary encoding/decoding layer that sits between standard TCP/IP protocols and the transport network. This intermediary handles the complexity of dealing with packet loss and latency, allowing end networks to use standard protocols while still achieving improved application performance without extensive retooling
3Reliability
If TCP/IP sessions are initiated at the destination network to transfer data across the transport network, then data transmission is improved for TCP/IP systems, but other protocols such as UDP/IP are affected by latency and packet loss
Solution Approach 1:
The patent creates a universal encoding/decoding mechanism that works across multiple protocols including TCP/IP, UDP/IP, and others. The encoding layer provides multi-functional protection against packet loss and latency for all protocols, making the system adaptable and versatile without being protocol-specific
Data Source
AI summary
Systems and methods for transporting data from a source network to a destination network by way of a transport network. Data transmission units (DTUs) from the source network are received at a server logically located between the source and the transport networks. These first DTUs are subdivided into second DTUs and are transmitted to the destination network by way of the transport network. Also transmitted are encoded or extra second DTUs that allow the original first DTUs to be recreated even if some of the second DTUs are lost. These encoded second DTUs may be merely copies of the second DTUs transmitted, parity second DTUs, or second DTUs which have been encoded using erasure correcting coding. At the destination network, the second DTUs are received and are used to recreate the original first DTUs. In the event an insufficient number of second DTUs are received, such that recreating the original first DTU cannot be accomplished, a re-transmission of the second DTUs is requested.
