At the same time, policies can be specified with sufficient detail in RPSL so that the low level router configurations can be generated from them. This paper is a discussion on using the RPSL to describe routing policies of relative AS in the Internet routing registry (IRR). We first analyze the relationships between a pair of ASes, and then explain how to specify various relative AS routing policies in RPSL. At last, we show an example of configuring routing policies using RtConfig that is a tool developed by the Routing Arbiter Project (RAP).展开更多

Methods: A database was set up by collecting and sorting out the relevant literature, and the analysis was made with the complex network. Results: It was found that Bai Jie Zi (白芥子 Semen Sinapis Albae), Xi Xin (细辛 Herba Asari), Gan Sui (甘遂 Radix Euphorbiae Kansui) and Yan Hu Suo (延胡索 Rhizoma Corydalis) were used as the basic prescriptions of drugs, Feishu (BL 13), Dazhui (GV 14) and Shanzhong (CV 17) were selected as the basic prescription of points. Conclusion: The knowledge obtained from the complex networks on the basic prescriptions of drugs and points for point-application in summer to treat diseases with attacks in winter can provide a data support for working out operation norms and carrying on verification research.展开更多
