Delay/disruption tolerant networking(DTN) is proposed as a networking architecture to overcome challenging space communication characteristics for reliable data transmission service in presence of long propagation delays and/or lengthy link disruptions. Bundle protocol(BP) and Licklider Transmission Protocol(LTP) are the main key technologies for DTN. LTP red transmission offers a reliable transmission mechanism for space networks. One of the key metrics used to measure the performance of LTP in space applications is the end-to-end data delivery delay, which is influenced by factors such as the quality of spatial channels and the size of cross-layer packets. In this paper, an end-to-end reliable data delivery delay model of LTP red transmission is proposed using a roulette wheel algorithm, and the roulette wheel algorithm is more in line with the typical random characteristics in space networks. The proposed models are validated through real data transmission experiments on a semi-physical testing platform. Furthermore, the impact of cross-layer packet size on the performance of LTP reliable transmission is analyzed, with a focus on bundle size, block size, and segment size. The analysis and study results presented in this paper offer valuable contributions towards enhancing the reliability of LTP transmission in space communication scenarios.

Based on the panel data of 30 provinces(autonomous regions,municipalities)in China from 2006 to 2019,the empirical study finds that the target values of economic growth expectation can promote high-quality economic development,and there is an inverted U-shaped relationship between elastic target constraints and high-quality economic *** elastic constraints can reduce the investment rate and improve the total factor productivity(TFP),which promotes high-quality economic development,but its mediating effect accounts for a small *** the improvement of the marketization degree,the inhibiting effect of elastic constraints on high-quality economic development *** analysis of the heterogeneity between the new or old normal and the levels of economic development shows that in the future,developed regions should set high target values and low elastic constraints,and underdeveloped regions should set high elastic constraints on the target values of economic growth expectation.
