Multicast Source Strategy Adaptation via Signaling Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multicast broadcast networks are inherently unreliable due to the use of UDP protocol in non-connected mode, leading to congestion when destinations or source changes increase, as existing methods require the source to know all destinations and often necessitate secure error correction mechanisms.
Innovation Solution
A method where a multicast source adjusts its broadcasting strategy based on received parameters, broadcasting an identifier of the new strategy in a multicast signaling channel, allowing the source to modify its strategy without knowing the specific destinations, and using secure unicast messages to avoid network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the source broadcasts strategy characteristics to all destinations using existing peer-to-peer methods, then the destinations can recover the stream, but the source must know all destinations and security mechanisms cause great network congestion
Solution Approach 1:
The patent extracts the strategy characteristics from the data stream itself, allowing destinations to autonomously recover and reconstruct the broadcasting strategy without requiring the source to explicitly transmit strategy information to each destination. This eliminates the congestion caused by security mechanisms while maintaining reliability.
Solution Approach 2:
Destinations are empowered to self-service by autonomously recovering strategy characteristics from the data stream and independently reconstructing the broadcasting strategy, eliminating the need for source-controlled security mechanisms and reducing network congestion.
2Adaptability or versatility
If the source sends strategy characteristics to destinations, then destinations can adapt to strategy changes, but the source must know the destinations which increases system complexity
Solution Approach 1:
The patent creates a universal mechanism where the data stream itself carries the strategy characteristics that any destination can interpret and adapt to, eliminating the need for the source to maintain knowledge of specific destinations while enabling universal strategy adaptation across all receivers.
3Reliability
If error correction codes or specific protocols are used to secure strategy transmission, then destinations can request resending, but this causes great congestion when destinations or strategy changes increase
Solution Approach 1:
The patent extracts strategy characteristics directly from the data stream content, eliminating the need for separate secure transmission channels and error correction protocols. Destinations recover strategy information autonomously from the stream itself, preventing congestion even when strategy changes occur frequently.

AI summary
A method of broadcasting data from a multicast source (S) to a plurality of receivers (CL) in a telecommunications network (1) in accordance with a broadcasting strategy, including: a step (E40) of receiving parameters (STAT, AG, CS); a step (E50) of adjusting said strategy as a function of said parameters; and in the event of modification of said strategy, a step (E70) of broadcasting in a multicast signaling channel, an identifier of this new broadcasting strategy.
