Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of diverse service discovery protocols and transport mechanisms in All-IP networks leads to compatibility issues during service discovery and consumption, particularly in multimedia sessions, where differences in video formats and transport protocols prevent seamless communication between devices.
Innovation Solution
A comprehensive translation mechanism is introduced, utilizing a service translation proxy that translates service discovery requests and responses across different protocols, detects incompatibilities, and adapts media formats and transport protocols to ensure compatibility between service providers and consumers, allowing for seamless service discovery and consumption across various devices and networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple diverse service discovery protocols are integrated in All-IP networks, then service variety and network flexibility increase, but compatibility issues arise between different protocols and devices
Solution Approach 1:
The patent introduces a service discovery protocol translator as an intermediary component that mediates between diverse service discovery protocols (SLP, SSDP, mSDP, etc.) and the service registry. This translator handles protocol conversion transparently, allowing devices using different protocols to communicate without direct compatibility between them, thus resolving the complexity issue while maintaining service variety
Solution Approach 2:
The service discovery function is segmented into separate components: service registrars, service resolvers, and protocol translators. This segmentation allows each component to handle specific protocol conversions independently, reducing overall system complexity while supporting multiple protocols simultaneously
2Ease of operation
If service discovery protocols are made protocol-specific, then implementation simplicity increases, but service discovery scope is limited to single protocol environments
Solution Approach 1:
The service registry and resolver are designed with universal functionality to work with multiple service discovery protocols simultaneously. The system can register and discover services using SLP, SSDP, mSDP, or other protocols through a unified interface, expanding service discovery scope while maintaining implementation simplicity through standardized operations
3Reliability
If video format compatibility is ensured through transcoding, then multimedia session compatibility improves, but system complexity and processing overhead increase
Solution Approach 1:
A media gateway is introduced as an intermediary that handles video format transcoding between service providers and consumers. The gateway transparently converts video formats (e.g., H.263, MPEG-2, VC-1) without requiring changes to end terminals, ensuring multimedia session compatibility while isolating complexity within the gateway component
4Adaptability or versatility
If transport protocol translation is implemented, then service accessibility across different transport mechanisms improves, but translation overhead and processing time increase
Solution Approach 1:
The service discovery protocol translator performs protocol translation and compatibility checks during the service discovery phase, before actual service consumption. This preliminary action identifies required transport protocol translations in advance, allowing optimization of translation processes and reducing time overhead during actual service delivery

AI summary
A service translation proxy provides a variety of translation services during the service discovery and subsequent service consumption phase. The service translation proxy receives a service request in accordance with one particular Service Description Protocol (SDP) and optionally translates the service request into the correct SDP as required using the appropriate service discovery interface. In addition, session description, session media, and session transport translations are implemented by the service translation proxy as required to support the service.
