In the paper, we propose a reliable asynchronous image transfer protocol, RAIT. RAIT applies a double sliding window method to node-to-node transfer, with one sliding window for the receiving queue, which is used to prevent packet loss caused by communication failure between nodes, and another sliding window for the sending queue, which prevents packet loss caused by network congestion. The routing node prevents packet loss between nodes by preemptive scheduling of multiple packets for a given image. RAIT implements a double sliding window method by means of a cross-layer design between the RAIT layer, routing layer, and queue layer. We demonstrate that RAIT guarantees a higher reliability of image transmission compared to the existing protocols.
在本文中，我们提出了一种可靠的异步图像传输协议 RAIT。RAIT 在节点到节点的传输中应用了双滑动窗口方法，其中一个滑动窗口用于接收队列，用于防止节点之间的通信故障导致的数据包丢失，另一个滑动窗口用于发送队列，用于防止网络拥塞导致的数据包丢失。路由节点通过为给定图像预先调度多个数据包来防止节点之间的数据包丢失。RAIT 通过 RAIT 层、路由层和队列层之间的跨层设计来实现双滑动窗口方法。我们证明，与现有协议相比，RAIT 保证了更高的图像传输可靠性。
