摘要:

针对云环境和物联网中存在海量、差异化的计算单元和终端设备,硬件资源和运算能力的差异对高可靠高性能的数据通信提出了新的挑战这一问题,提出了支持差异化可协商的数据通信机制。提出参数协商方法,发送端根据接收端能力不同进行参数协商,实现差异化、可协商的数据通信;设计重传反馈机制,发送端通过接收端反馈的数据接收情况动态调整发送速率和重传数据,提高通信效率和可靠性。实验结果表明,所提机制能够根据接收端能力差异,进行动态自适应、高效、并行通信。

关键词: 自适应, 差异化, 可协商, 滑动窗口, 通信机制

Abstract:

In view of the massive and differentiated computing units and terminal devices in the cloud environment and the Internet of things, the differences in hardware resources and computing capabilities posed new challenges to high reliability and high performance data communication, a data communication mechanism supporting differentiation and negotiation was proposed.A parameters negotiation method was proposed, and parameters were negotiated by the sender according to the difference of the receiver capability to achieve differentiated and negotiable data communication.A retransmission feedback mechanism was designed, and the transmission rate was dynamically adjusted and the data was retransmitted based on the data reception feedback of the receiver by the sender to improve communication efficiency and reliability.The experimental results show that the proposed mechanism can perform dynamic adaptive, efficient and parallel communication according to the difference of the receiver capability.

Key words: adaptive, differentiated, negotiable, sliding window, communication mechanism
