Adaptive Streaming Metadata Modulation for Network Traffic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content transmission systems using Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (DASH) technology face issues with increased network traffic due to excessive client connections, leading to traffic overload and inefficiencies in content configuration for diverse communication networks.
Innovation Solution
A method and apparatus for controlling traffic by modulating metadata to exclude information on certain representations from the metadata when network traffic exceeds a threshold, and transmitting content based on maximal bandwidth, using a communication network device to manage traffic between the server and clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If client control streaming scheme is used to reduce server load, then server overload is prevented, but network traffic increases due to all clients using maximal bandwidth
Solution Approach 1:
A communication network device is introduced as an intermediary between the server and clients. This device receives metadata from the server, modulates it by excluding information on certain representations based on network traffic conditions, and transmits the modulated metadata to clients. This intermediary controls network traffic by preventing clients from requesting high-bandwidth representations when the network is congested, thus reducing overall traffic volume while maintaining server control capacity.
2Adaptability or versatility
If metadata includes all representation information to provide full adaptability, then client selection flexibility is maximized, but network traffic increases
Solution Approach 1:
The communication network device extracts and excludes information on certain representations from the metadata based on current network traffic conditions. By removing unnecessary representation information that would lead to high bandwidth consumption, the device reduces metadata size and subsequent network traffic while maintaining adaptability for appropriate content selections.
Solution Approach 2:
The metadata is dynamically modulated based on real-time network traffic conditions. The communication network device adjusts which representation information is included in the metadata according to current network status, making the system adaptable to changing traffic conditions rather than using a static full-metadata approach.
3Adaptability or versatility
If server provides all content representations to ensure complete coverage, then content availability is maximized, but network bandwidth consumption increases
Solution Approach 1:
The communication network device acts as a mediator that receives complete content representations from the server in metadata form, then selectively excludes certain representations based on network bandwidth conditions before transmitting to clients. This maintains content availability in the server while controlling actual network bandwidth consumption by preventing requests for high-bandwidth content during congested periods.

AI summary
A method for network operators to control traffic between a server and a client so that client-induced traffic preemption may be prevented is provided. The method includes the processes of an operator determining a network status, the network in which a server is streaming content via a multi-media transmission system, in accordance with a status of the network, determining whether to modify meta data by considering a set of predetermined conditions, and transmitting to a terminal data reflecting the modification decision.
