Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communication systems face bottlenecks due to heavy network traffic, especially with the increased popularity of streaming media content, leading to bandwidth restrictions and inefficiencies, as they often rely on single network links and blind transmission techniques that result in data loss without recovery mechanisms.
Innovation Solution
A hybrid network configuration that utilizes multiple network links with different communication techniques, including bi-directional and uni-directional links, to efficiently deliver data communication content, incorporating techniques like automatic repeat requests, hybrid retransmission, and statistical feedback for data loss recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If blind transmission techniques are used to avoid utilizing network resources for acknowledgments and retransmission requests, then network resource utilization is reduced, but data loss occurs without recovery mechanisms
Solution Approach 1:
The system segments the data transmission process into two distinct phases: an initial blind broadcast phase for efficient content distribution, followed by a targeted retransmission phase for lost packet recovery. This segmentation allows the system to achieve both low network resource utilization during broadcast and high reliability through selective retransmission only when needed.
Solution Approach 2:
The system implements feedback mechanisms where receiving devices report packet loss statistics to the transmitting device. This feedback enables the transmitting device to identify which packets were lost and initiate retransmission only for those specific packets, rather than retransmitting everything, thus maintaining efficiency while improving reliability.
2Reliability
If feedback techniques are utilized to provide acknowledgment of receipt and request for retransmission, then data delivery reliability is improved, but network resources are heavily utilized and data latency is introduced
Solution Approach 1:
Instead of using full feedback mechanisms that require acknowledgment for every single packet (excessive action), the system uses partial feedback by aggregating packet loss statistics and only initiating retransmission when loss is detected. This partial feedback approach maintains reliability for affected data while avoiding the network resource exhaustion that would result from complete feedback mechanisms.
3Device complexity
If single network links are used for data communication, then device complexity is reduced, but bandwidth restrictions and network bottlenecks occur during heavy traffic
Solution Approach 1:
The system makes the broadcast network link universal by enabling it to serve multiple functions: initial content distribution to all devices, and subsequent retransmission of lost packets to specific devices. This multi-functionality allows a single network link to handle both efficient broadcast communication and reliable unicast communication, avoiding the need for separate dedicated links while maintaining high productivity.

AI summary
Systems and methods which provide data communication content delivery through a hybrid network implementation are disclosed. A hybrid network configuration may utilize a broadcast communication technique to deliver large amounts of data communication content to one or more mobile communication device via uni-directional network links and a uni-cast communication technique via bi-directional network links with the one or more mobile communication device to facilitate delivery and utilization of the data communication content. Data content delivery loss recovery techniques implemented according to embodiments of the invention utilize network links of the hybrid network other than or in addition to the uni-directional network links to implement loss recovery techniques such as a hybrid repeat technique, a hybrid retransmission technique, hybrid statistical feedback technique, and/or combinations thereof.
