Multi-service Platform Integrating Switched Fabric With VMEbus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VMEbus systems can only support one simultaneous high-bandwidth communication, failing to meet applications requiring simultaneous high-speed data transfers between payload modules.
Innovation Solution
Integration of a switched fabric network alongside the VMEbus network, where the switched fabric network operates concurrently or in parallel to handle high-speed data transfers while the VMEbus manages the system, using standards like InfiniBand, Serial RapidIO, or FibreChannel, and employing keying mechanisms to ensure compatibility and prevent incompatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a shared multi-drop bus architecture is used, then system compatibility and ease of operation are maintained, but the system can only support one simultaneous communication, limiting bandwidth and productivity
Solution Approach 1:
The system is segmented into two distinct network layers: the VMEbus network for control and management functions, and the switched fabric network for high-speed data transfers. This segmentation allows each network to be optimized for its specific function, enabling simultaneous high-bandwidth communications without compromising system compatibility
Solution Approach 2:
Payload modules act as intermediaries between the VMEbus network and the switched fabric network. These modules include both VMEbus interfaces and switched fabric interfaces, enabling translation and coordination between the two networks while maintaining their operational independence
2Productivity
If the VMEbus architecture is modified to support simultaneous high-speed transfers, then productivity increases, but the existing VMEbus network architecture is altered, increasing device complexity
Solution Approach 1:
The solution merges the VMEbus network and switched fabric network into a hybrid architecture where both networks coexist and operate simultaneously. The VMEbus network maintains its original operation for control functions, while the switched fabric network provides additional high-speed pathways, achieving enhanced productivity without modifying the VMEbus architecture
Solution Approach 2:
The payload modules are designed with multi-functionality, supporting both VMEbus interfaces and switched fabric interfaces. This universality allows the same hardware platform to handle both control communications and high-speed data transfers, maintaining ease of operation while enabling simultaneous high-bandwidth transfers
3Reliability
If a switched fabric network is added alongside VMEbus, then simultaneous high-speed transfers are enabled, but device complexity increases
Solution Approach 1:
The system dynamically selects the appropriate network for each communication task: VMEbus for control and management, and switched fabric for high-speed data transfers. This dynamic allocation optimizes resource utilization and maintains reliability while managing complexity through intelligent traffic routing
