摘要

越来越多的应用程序对其数据传输有最后期限要求,例如360°视频,云VR游戏和自动驾驶。这些应用程序通常需要带宽。幸运的是,这些应用程序的数据可以分成具有不同优先级的多个块,从而可以通过将某些块优先于其他块来减少带宽消耗。然而,现有的传输层太原始了,无法实现这一点。因此,这些应用程序被迫构建自己定制的复杂车轮。在这项工作中,我们提出了截止日期感知传输协议(DTP)来提供截止日期前的交付服务。应用程序向DTP表示数据的截止日期和元数据。然后DTP尝试通过调度块来满足需求。与现有协议相比,DTP提供了有意义的服务,减轻了应用程序开发人员的负担。

DTP: Deadline-aware Transport Protocol
More and more applications have deadline requirements for their data delivery such as 360° video, cloud VR gaming and autonomous driving. Those applications usually are band-width hungry. Fortunately, the data of those applications can be split into multiple blocks with different priorities making it possible to reduce the bandwidth consumption by prioritizing some blocks over others. However, the existing transport layer is too primitive to accomplish that. So those applications are forced to build their own customized and complex wheels. In this work, we propose Deadline-aware Transport Protocol (DTP) to provide deliver-before-deadline service. The application expresses the deadline and metadata of the data to DTP. Then DTP tries to meet the requirement by scheduling blocks. Compared to existing protocols, DTP provides meaningful service and reduces the burden of the application developer.
