Bus Virtualization via VLAN Mapping for Parallel Network Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network interfaces serialize parallel signals for transport over LAN and WAN, leading to performance losses and increased costs due to serialization and demapping processes.
Innovation Solution
Implementing bus virtualization by mapping control and data lines to logically segmented virtual local area networks (VLANs), allowing parallel communications to be maintained without serialization, thereby extending the parallel bus over networks between computing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If parallel signals are serialized for transport over network, then transmission distance is extended, but transmission performance deteriorates and costs increase
Solution Approach 1:
The patent segments the parallel bus signals into multiple separate communication channels, with each channel carrying a portion of the parallel data. This segmentation allows the signals to be transmitted over network infrastructure while maintaining their parallel nature, avoiding the performance degradation associated with traditional serialization.
Solution Approach 2:
The patent introduces network adapters as intermediary devices that facilitate parallel communication over network infrastructure. These adapters translate bus signals into network-compatible formats without requiring full serialization, acting as a mediator between the parallel bus and network transport layers.
2Length of stationary object
If parallel signals are serialized for transport over network, then transmission distance is extended, but economic costs increase
Solution Approach 1:
By segmenting parallel signals into multiple channels that can be transmitted simultaneously over existing network infrastructure, the patent eliminates the need for expensive serialization/deserialization hardware and processing, thereby reducing economic costs while extending transmission distance.
3Adaptability or versatility
If serialization and demapping processes are used, then parallel communications can be transported over network, but transmission overhead increases
Solution Approach 1:
Network adapters serve as intermediaries that enable network transport of parallel signals without requiring complex serialization and demapping processes. The adapters handle the conversion locally, reducing transmission overhead by avoiding repeated serialization/deserialization cycles at multiple network points.

AI summary
To reduce performance losses and costs associated with serializing parallel communications when communicating with other computing devices over a local area network (“LAN”) or a wide area network (“WAN”), bus virtualization is provided to maintain parallelization for inter machine communications over a network. Control lines and data lines associated with a parallel bus communication can be received by a network adapter, and instead of serializing the communications, the network adapter can map each of the control and data lines to respective virtual local area networks (“VLAN”). Multiple VLANs can exist together on a LAN or WAN while logically segmented, allowing the respective VLANs to facilitate communications for the control and data lines over the network.
