Local Data Distribution Device for Cloud Video Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud computing architectures face bandwidth challenges when managing multiple high-definition video streams, especially during videoconferencing, as traditional methods require significant bandwidth for uplink and downlink communications across wide area networks, leading to increased network traffic and resource consumption.
Innovation Solution
Implementing a data distribution device within a local area network that selectively routes and compresses multimedia data between thin clients, reducing the need for data to be transmitted to a central cloud server, thereby minimizing bandwidth usage on wide area networks by caching and forwarding communications locally and transcoding streams for efficient distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If all video streams are routed through the central cloud server for processing and distribution, then centralized control and resource management are achieved, but WAN bandwidth consumption increases significantly
Solution Approach 1:
The patent segments the video stream distribution function by introducing local distribution servers at each LAN site. These local servers handle video stream distribution within the LAN, while the central cloud server only manages control functions and distributes to local servers. This segmentation reduces WAN bandwidth consumption by eliminating redundant video stream transmissions across the WAN.
Solution Approach 2:
The patent introduces local distribution servers as intermediary components between the central cloud server and end-user clients. These intermediaries receive compressed control streams from the cloud server and locally generate and distribute the full-resolution video streams within the LAN, acting as a buffer that reduces WAN traffic while maintaining centralized control.
2Loss of energy
If video streams are compressed to reduce bandwidth usage, then WAN bandwidth consumption decreases, but processing requirements at the server increase
Solution Approach 1:
The patent segments the processing workload by having the central cloud server perform only control function processing and compression of control streams, while local distribution servers handle the computationally intensive task of generating full-resolution video streams from these compressed control streams. This distribution of processing tasks balances the load and reduces the processing power requirement at any single location.
3Adaptability or versatility
If multiple clients participate in videoconferencing simultaneously, then communication capability increases, but aggregate bandwidth requirements increase exponentially
Solution Approach 1:
The patent segments the videoconferencing function by implementing local distribution servers at each LAN site that handle all video stream distribution within that location. This allows multiple clients at the same LAN to communicate without requiring WAN bandwidth, while still maintaining connection to the central cloud server for control functions. The segmentation of communication domains reduces aggregate bandwidth requirements.
Solution Approach 2:
The patent merges multiple video streams at the local distribution server level, where a single compressed control stream from the cloud server is used to generate and distribute video to multiple clients simultaneously. This merging approach allows one upstream connection to serve multiple downstream clients, reducing the aggregate bandwidth requirement proportional to the number of clients served by each local server.

Example embodiments of the present disclosure concern a system and method for selectively intercepting communications in a cloud computing environment by receiving communications from one or more thin-client terminal systems connected via a local area network, determining one or more recipients of each received communication, and based on a determination that the one or more recipients of a communication include only thin-client terminal systems connected via the local area network, intercepting the communication and preventing the communication from being transmitted to a central server connected to the local area network via a wide area network, storing the communication, and forwarding the communication to the one or more recipients connected to the local area network.
