摘要:
Disclosed are an apparatus and a method for swapping headers for authenticating policy based domains and tracing paths at the time of high-reliable data plane transmission. The method includes receiving packets forwarded through predetermined paths, confirming whether the received packets are normal packets, determining whether the path identification information corresponding to the paths of the received packets is present in a header information storage unit of a domain receiving the packets, swapping the headers included in the packets to swapping headers of the header information storage unit by using the identification information if it is determined that the path identification information is present, and correcting the path tracing information. By this configuration, degradation in data plane performance due to the lengths of headers can be solved.

摘要:
Provided is a method for preparing (S)-5-chloro-N-((3-(4-(5,6-dihydro-4H-1,2,4-oxadiazin-3-yl)phenyl)-2-oxooxazolidin-5-yl)methyl)thiophene-2-carboxamide derivatives of Formula (I) which are useful as blood coagulation factor Xa inhibitors, and said method using 1-fluoro-4-nitrobenzen as a starting material. According to the method of the present invention, (S)-5-chloro-N-((3-(4-(5,6-dihydro-4H-1,2,4-oxadiazin-3-yl)phenyl)-2-oxooxazolidin-5-yl)methyl)thiophene-2-carboxamide derivatives of Formula (I) which are useful as blood coagulation factor Xa inhibitors can be prepared in a high purity and a high yield.
摘要:
An open access node receives a dynamic IP address corresponding to a terminal that requests a connection from a specific server, and provides the dynamic IP address to the terminal. Next, the open access node receives a service that is requested by a user from the terminal that is connected using the dynamic IP address, and stores a MAC address of the terminal and a service in a database. When the terminal again requests a connection, the open access node identifies a service that is requested by a user of the terminal based on the MAC address of the terminal.
