Selective Field Transmission: Bandwidth Efficient Communication Under Standardized Message Schemas
提出SFT中间件，在发布-订阅系统中按接收方需求传输标准消息字段，并评估其带宽与延迟效果。
核心要点
- 开发者常在标准消息互操作性与定制消息降带宽之间权衡。
- SFT将传输内容与静态消息类型解耦，保留未修改标准接口。
- 接收方声明或自动推导所需组件，发布方仅序列化并发送对应子集。
- 评估显示可显著降低带宽，且无可测逐消息延迟开销。
验证范围与局限：摘要未说明具体机器人、任务或实验环境。
英文摘要 (Abstract)
In this paper, we introduce and evaluate Selective Field Transmission (SFT), a middleware mechanism that decouples transmission content from statically defined message types in publish-subscribe systems. Industrial and robotics developers often face a dilemma: They can follow established best practices and use standard message types, such as in the Robot Operating System 2 (ROS 2) and COVESA projects, to benefit from reusable and interoperable interfaces, or they can introduce proprietary, project-specific message types tailored to receiver requirements to reduce bandwidth. SFT resolves this trade-off by dynamically adapting the transmitted message components to each receivers actual needs while preserving unmodified standard interfaces. Receivers declare or automatically derive the required message components, which are communicated to the publisher. The publisher then serializes and transmits only the required component subset per receiver with minimal developer intervention. Our evaluation shows that SFT achieves significant bandwidth reductions without measurable per-message latency overhead, with savings proportional to the number and size of unused fields.
