Method for Forwarding Data Packets in a Communication Network and Communication Network Having Flooding Transport Properties

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a simplified and robust method for forwarding data packets in a communication network. Instead of complex traditional routing, data packets are 'flooded' through all network nodes (repeaters), with each packet containing specific individualizing information (such as recipient, geography, or security keys). Only authorized receivers who possess this information can access the packet's content, enabling secure and efficient data delivery without the need for routing tables or traditional addressing schemes.

Use CasesContent extracted from patent full text and abstract with AI.

• Large-scale content distribution (e.g., live video streaming or over-the-air software updates) across geographically dispersed users.
• Secure group communication where only authorized participants can access shared information, useful in confidential enterprise environments or defense networks.
• Simplified network infrastructures for emerging markets or disaster recovery scenarios where rapid deployment, low cost, and reliability are priorities.
• Resilient sensor networks (IoT) where nodes can freely join or leave, and data needs to reach all interested parties without central management.
• Broadcast messaging platforms with built-in security and anonymity features for mass notification systems.

BenefitsContent extracted from patent full text and abstract with AI.

• Eliminates the need for complex routing protocols and routing tables, reducing management overhead and potential misconfiguration.
• Enhances security and privacy as only intended recipients (with the correct individualizing information/key) can access the data, regardless of packet propagation.
• Increases network robustness and fault-tolerance, as the flooding approach is not susceptible to single points of failure.
• Simplifies network device requirements, allowing use of low-cost hardware (repeaters instead of routers), reducing infrastructure expenses.
• Supports easy scalability and rapid deployment, as new nodes or users can be added with minimal configuration.
• Enables filtering by geography or priority to limit unnecessary data transmission and manage network load.

Patent Abstract

A method for forwarding data packets in a communication network N is disclosed, comprising the steps of: a) generating a stream of data packets at a first subscriber (2); b) adding to each of the data packets in said stream a recipient individualizing information (6) to form individualized data packets (IDP); c) forwarding the individualized data packets (IDP) to a first repeater node (RP1); d) flooding the individualized data packets (IDP) from the first repeater node (RPl) to any further subscriber connected to said first repeater node (RP1); e) flooding the individualized data packets (IDP) to any further repeater node (RP2, RP3) connected to said first repeater node (RP1); f) flooding the individualized data packets (IDP) in any further repeater node (P4 to RP6) analogous to the steps d) and e); g) connecting any possible further subscriber (4) of said stream of individualized data packets (IDP) to a repeater node selected from a group containing the first repeater node (RP1) and any further repeater nodes (RP2 to RP6) and g) enabling only those of said any possible subscribers (4) to access a content of said individualized data packets (IDP) when able to identify as authorized subscriber by knowledge of the recipient individualizing information (6) added to the data packets.
