1Loss of energy
If network encoding is implemented to reduce bandwidth consumption, then bandwidth efficiency is improved, but determining relay nodes and optimizing bandwidth allocation becomes complex
Solution Approach 1:
The patent segments the network into multiple elementary networks, each capable of independently implementing network encoding. This segmentation allows the complex problem of determining relay nodes in the entire network to be broken down into simpler sub-problems for each elementary network, reducing overall complexity while maintaining bandwidth efficiency.
Solution Approach 2:
The patent applies local quality by allowing different elementary networks to have different encoding schemes and relay node configurations optimized for their specific characteristics. Each elementary network can be independently configured with appropriate relay nodes and encoding parameters, rather than applying a uniform complex scheme across the entire network.
2Manufacturing precision
If bandwidth is allocated to improve decoding capacity for all destination nodes, then decoding quality is improved, but bandwidth resources are wasted on nodes that already have sufficient capacity
Solution Approach 1:
The patent implements feedback mechanisms where destination nodes report their decoding capacity and quality requirements to the network controller. This feedback allows the system to dynamically identify which nodes actually need additional bandwidth allocation for decoding, preventing waste on nodes that already have sufficient capacity while ensuring adequate resources are allocated to those that need them.
Solution Approach 2:
The patent dynamically adjusts bandwidth allocation parameters based on the specific needs of each destination node. By changing allocation parameters selectively for different nodes based on their decoding capacity and quality requirements, the system optimizes the balance between decoding quality improvement and bandwidth resource efficiency.

AI summary
One embodiment of the invention pertains to a method for allocating bandwidth in a communications network, characterized in that it comprises steps for:a) determining a subset of elementary networks from a set of possible elementary networks in a communications network, the elementary networks of the subset each being capable of simultaneously implementing a elementary network encoding scheme;b) determining at least one critical destination node in the communications network;c) allocating at least one bandwidth portion released by an application of the elementary network encoding scheme in at least one elementary network of the subset, for a transmission of at least one additional data unit to the at least one critical destination node.
