Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peer-to-peer networking environments face challenges in seamlessly interconnecting and accessing devices and services across different networking environments due to protocol and format incompatibilities, leading to difficulties in device and service discovery, description, and connectivity.
Innovation Solution
The implementation of a tunneling mechanism that provides tunnel sockets between network computing environments, allowing for the translation of device and service descriptions into a uniform format for discovery and access across various platforms and protocols, enabling transparent interconnection and interaction of devices and services regardless of their underlying platforms or locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices and services use different protocols and formats in heterogeneous networking environments, then each environment can maintain its own operational standards and compatibility, but interconnection and discovery across environments become difficult and complex
Solution Approach 1:
The patent introduces a tunneling mechanism that acts as an intermediary between heterogeneous networking environments. The tunneling socket creates a virtual communication channel that translates and bridges different protocols (such as SLP, MDNS, Jini, UPnP) without requiring modification of the underlying protocols. This mediator approach allows devices in different environments to communicate while maintaining their native protocol compatibility, thus resolving the contradiction between protocol adaptability and interconnection complexity
Solution Approach 2:
The tunneling socket implements a universal interface that can handle multiple different networking protocols and formats through a single unified mechanism. Rather than requiring separate integration solutions for each protocol pair, the tunneling socket provides multi-functional capability to translate between various protocols (SLP, MDNS, Jini, UPnP, etc.), reducing overall system complexity while maintaining broad adaptability
2Adaptability or versatility
If protocol translation is implemented to enable cross-environment communication, then interoperability improves, but protocol modification requirements increase system complexity and risk
Solution Approach 1:
The tunneling mechanism serves as a protocol-agnostic intermediary that translates at the application layer rather than modifying underlying protocols. The tunneling socket intercepts communication between devices and translates messages between different protocol formats without requiring changes to the original protocols or their implementations, thus achieving interoperability while minimizing complexity and risk
Solution Approach 2:
The tunneling socket creates virtual copies of protocol messages and translates them between formats. Rather than modifying original protocol implementations, the system creates translated copies of communication messages that conform to the target protocol format, allowing cross-environment communication while preserving the integrity and simplicity of original protocols
3Ease of operation
If a unified device description format is implemented across all networking environments, then discovery and translation become simpler, but flexibility to support legacy devices with format-specific descriptions is reduced
Solution Approach 1:
The tunneling mechanism implements local quality by allowing each networking environment to maintain its native device description format (SLP, MDNS, Jini, UPnP, etc.) while the tunneling socket performs format-specific translation as needed. Each environment operates with its own format characteristics locally, while the tunneling mechanism provides the necessary translation capability to enable cross-environment discovery, thus achieving both simplicity and legacy support
Solution Approach 2:
The tunneling socket dynamically changes format parameters based on the source and target environments. When translating device descriptions between environments, the system adjusts format parameters (such as protocol-specific fields, data structures, and encoding formats) to match the target environment's requirements, enabling universal discovery while preserving legacy format compatibility
Data Source
AI summary
Method and apparatus for multiplexed data communication tunneling channels. Embodiments of the tunneling mechanism may provide tunnel sockets between networking environments that allow a node in one networking environment to interconnect with network resources in other networking environments. A tunnel socket is a proxy or bridge across a peer-to-peer network between different networking environments. Using the tunneling mechanism, descriptions of network resources in one format may be translated to advertisements in a uniform description format, which may then be published on the network. The published advertisements may be discovered by entities in other networking environments and translated into formats of the other networking environments for access by the entities. To the entities, the resources appear to be in their local networking environment.
