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。
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.
