Realtime Kernel Stream Graph for Secure Virtual Area Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently managing and processing data streams in a virtual area application, particularly in constructing and configuring stream handlers for real-time data processing, and ensuring secure, reliable, and efficient communication between network nodes.
Innovation Solution
The Realtime Kernel supports remote configuration of stream handlers using the STRAW service to manage secure, connection-oriented data streams, employing a directed graph of processing elements and utilizing the STRAW transport protocol for encrypted, sequenced data transmission, along with components like the audio stream service and media channel service for audio and text communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a complex stream handler configuration is used to process multiple data streams, then the processing capability is improved, but the system complexity increases
Solution Approach 1:
The stream handler is divided into multiple independent processing elements (audio calculation objects, mixing objects, effect objects) that can be configured and instantiated separately. Each processing element handles a specific function, allowing the system to process multiple data streams through modular components rather than a monolithic complex handler.
Solution Approach 2:
The transport bus acts as an intermediary that manages the directed graph of processing elements. It receives configuration instructions from the area service, instantiates the appropriate processing objects, and coordinates data flow between them, thereby reducing the complexity of direct configuration relationships.
2Adaptability or versatility
If remote configuration of stream handlers is implemented, then the system adaptability is improved, but the configuration processing time increases
Solution Approach 1:
The area service pre-configures stream handler specifications before runtime. The configuration is parsed and processing elements are instantiated in advance based on SODA definitions, so that when actual data stream processing is needed, the infrastructure is already in place and ready for immediate operation.
Solution Approach 2:
The system uses SODA (Semantics On Demand) definitions as templates that can be copied and instantiated multiple times. When remote configuration is received, the area service copies the predefined SODA definitions and instantiates the corresponding processing elements, avoiding the need to recreate entire configuration structures from scratch.
3Reliability
If STRAW protocol with encryption and sequencing is used, then the communication reliability is improved, but the data transmission overhead increases
Solution Approach 1:
The patent extracts and separates the reliability and security functions into dedicated STRAW protocol layers that operate independently from the core data processing functions. The encryption and sequencing mechanisms are implemented as separate protocol components that can be configured independently, allowing the system to maintain security without embedding it throughout every processing operation.

AI summary
A realtime kernel supports realtime communications between communicants operating on respective network nodes. The realtime kernel handles the complex tasks of connecting to communicants, virtual areas, and other network resources, switching those connections in response to user inputs, and mixing realtime data streams. The realtime kernel enables developers to focus on developing high-level communications functionality instead of low-level plumbing code. The realtime kernel imposes relatively low computational resource requirements so that realtime communications performance can be achieved using a wide range of computing devices and network connections that currently are available.
