Multicast Data Segmentation for Source Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High demand for data file retrieval over communication networks can lead to resource depletion and delayed responses at source devices due to concurrent processing of multiple requests, causing negative impacts on response times.
Innovation Solution
Segmenting data files into multiple modules for multicast transmission, with error detection and correction, and cyclic transmission, allowing destination devices to receive data modules out of sequence while maintaining the ability to reconstruct the entire file, and using a combination of multicast, point-to-point, and broadcast connections to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-to-point data transfer is used for each request, then data transmission can be established between source and destination devices, but memory and processor resources at the source device are depleted when handling high numbers of concurrent requests
Solution Approach 1:
Multiple individual point-to-point data transmission requests are merged into a single multicast transmission. The source device creates one execution process that handles multiple destination devices simultaneously by sending data packets to a multicast group address, rather than creating separate processes for each destination device. This consolidates memory and processor resource usage while maintaining reliable data delivery to all requested devices.
Solution Approach 2:
The multicast transmission mechanism provides multi-functionality by serving multiple destination devices through a single transmission channel. The source device's execution process becomes universal, capable of simultaneously managing data delivery to any number of destination devices that have joined the multicast group, rather than being dedicated to a single point-to-point connection.
2Productivity
If multiple concurrent processes are created to handle multiple data requests, then all requests can be processed simultaneously, but response time is negatively impacted due to resource depletion and processing delays
Solution Approach 1:
Multiple sequential request processing operations are merged into a single concurrent multicast transmission process. The source device establishes one execution process that simultaneously handles data delivery to multiple destination devices, eliminating the sequential overhead of creating and managing multiple individual processes while maintaining high productivity through parallel data distribution.
3Reliability
If data files are transmitted as complete units, then data integrity is maintained, but transmission efficiency is reduced and resource usage increases when the same file is requested by multiple destination devices
Solution Approach 1:
Complete data files are segmented into smaller data packets that can be efficiently transmitted through multicast channels. The source device divides the file into manageable segments, transmits them via multicast to multiple destination devices simultaneously, and ensures data integrity through proper packet addressing and reconstruction processes at each destination.
Solution Approach 2:
Multiple transmissions of the same complete data file to different destination devices are merged into a single multicast transmission. The source device sends one copy of each data packet to the multicast group, and all destination devices receive and process the same segments, dramatically reducing transmission energy and resource usage compared to sending separate copies to each device.
Data Source
AI summary
Methods and systems for transmitting and receiving data, such as, for example, entertainment data, are presented. In one example, a data file is segmented into a plurality of data modules. A header is generated for each of the data modules, with the header including a module identifier for the data module associated with the header. An indication of a number of the plurality of data modules associated with the data file, and at least one multicast address from which the plurality of modules may be received via a multicast transmission, are generated and transmitted. The data modules with their associated headers are transmitted over a communication network in the multicast transmission.
