摘要:: RDP( Remote Desktop Protocol)是微软的终端服务协议，它提供了客户端远程访问服务端的能力。针对RDP在广域网或者无线网络环境中，其交互过程仍存在较大时延的问题，文中提出了一种基于混合阶Markov算法的预测模型。该模型是根据客户端过去的输入事件预测下一时刻的屏幕更新事件，在服务端更新事件到来前更新屏幕，从而有效增强用户体验，减少更新时延。实验结果表明该模型具有很高的准确率和覆盖率，从而证明了该预测模型算法能有效地减少传输时延。

Abstract:: RDP ( Remote Desktop Protocol) is a Microsoft terminal services protocol,which provides the ability of the client remote ac-cess server. Aiming at the problem of large delay in interaction for RDP in WAN or wireless network environment,a prediction model based on mixed-order Markov algorithm is proposed. The model is to predict the next input events according to the client's past screen update event of the moment,before the arrival of the server update event to update the screen,so as to effectively enhance the user experi-ence,reducing the update delay. The experimental results show that the model has a high accuracy rate and coverage,thus proving the forecasting model algorithm can effectively reduce the transmission delay.
