Self-Replicating Code for Network Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods in large communication networks, such as multicasting, face inefficiencies due to bandwidth constraints and lack of real-time transfer status monitoring, as well as the need for pre-installed software on receiving devices, and the risk of self-replicating code propagating uncontrollably.
Innovation Solution
Self-replicating code that establishes and maintains communication channels between nodes in a network, allowing data transfer without pre-installed code on nodes and enabling real-time monitoring of transfer status, while avoiding uncontrollable propagation.

Engineering Contradiction Analysis
1Productivity
If multicasting is used to transfer data to multiple devices simultaneously, then transfer efficiency is improved, but network bandwidth is quickly used up
Solution Approach 1:
The patent segments the data transfer process into multiple stages: first transferring a small bootstrap code via multicasting, then having each receiving device independently download the remaining large data portion. This segmentation allows the network to handle many devices simultaneously with minimal bandwidth consumption during the initial phase, while individual devices perform the bulk data transfer independently.
Solution Approach 2:
The patent introduces a bootstrap code as an intermediary element that enables receiving devices to become self-sufficient. This small code contains the information needed for devices to independently access and download the full data set from external sources, acting as a mediator between the central server and individual devices.
2Ease of operation
If multicasting is used to transfer data to multiple devices, then individual device handling is avoided, but receiving devices need pre-installed software to receive the multicast
Solution Approach 1:
Instead of requiring receiving devices to have pre-installed software to receive multicasted data, the patent inverts the approach by multicasting the software itself (bootstrap code) first. This allows devices to acquire the necessary software through the multicast process, eliminating the prerequisite of pre-installed receivers.
3Adaptability or versatility
If traditional worms replicate themselves on network devices, then self-replicating code can be used, but communication channels between parent and child worms are not maintained
Solution Approach 1:
The patent implements feedback mechanisms where receiving devices send acknowledgments back to the sender after successfully executing the bootstrap code and completing data transfer. This feedback loop allows the sender to monitor transfer status and verify successful delivery, maintaining communication channels throughout the process rather than losing them after replication.
Data Source
AI summary
A method and communication network for transferring data is described. For the method, responsive to executing first code in a first node in a communication network, the first node establishes a communication channel with a second node, replicates itself to generate second code, and provides the second code to the second node over the communication channel. Responsive to executing the second code in the second node, the second node establishes a communication channel with a third node, replicates itself to generate third code, and provides the third code to the third node over the communication channel. The second node then receives data from the first node over the communication channel and executes the second code to handle the data. The third node then receives the data from the second node over the communication channel and executes the third code to handle the data.
