延迟/中断容忍网络(DTN)是为了实现自动化网络通信而开发的，尽管空间通信通常具有较长的链路延迟和频繁的链路中断。DTN汇聚层适配器(CLA)协议在非对称空间通信信道上的性能尚未得到全面表征。在这篇文章中，我们提出了一种用于在非对称信道速率的空间通信基础设施上进行可靠数据传输的DTN CLA协议的实验性能评估，特别是最近开发的Licklider传输协议(LTP)CLA(即LTPCL)。LTPCL的性能与其他两个可靠的类TCPCLA和TCPCLA和LTPCL的混合进行了比较，用于在存在高度不对称的信道速率的情况下进行长时延环月通信。在链路时延很长、链路中断时间较长的深空通信场景中，对LTPCL进行了评估和分析。
Delay/disruption tolerant networking (DTN) was developed to enable automated network communications despite the long link delay and frequent link disruptions that generally characterize space communications. The performance of DTN convergence layer adapter (CLA) protocols over asymmetric space communication channels has not yet been comprehensively characterized. In this paper, we present an experimental performance evaluation of DTN CLA protocols for reliable data transport over a space communication infrastructure involving asymmetric channel rates, with particular attention to the recently developed Licklider transmission protocol (LTP) CLA (i.e., LTPCL). The performance of LTPCL is evaluated in comparison with other two reliable CLAs, TCP CLA and a hybrid of TCP CLA and LTPCL, for long-delay cislunar communications in the presence of highly asymmetric channel rates. LTPCL is also evaluated and analyzed in a deep-space communication scenario characterized by a very long link delay and lengthy link disruptions.
