Title: Method for re-sorting management information modeling language
Inventor: JUNG MOON SANG
IPC: G06F9/44
Filed: 1998-12-24
Abstract: PURPOSE: A method for re-sorting a management information modeling language is provided to improve an execution speed of a program, and remove a complex structure to increase an efficiency, by performing the re-sort operation in advance using a grade value when the data type of an ASN.1 is declared, the language being used in conversion of the information between network management domains. CONSTITUTION: A grade value is initialized(401). The first loop for the declaration of the ASN.1 data type and the second loop for a data type to be compared are configured(402,403). A data type with a lower grade in the frist and second loops is searched(404,405). It is determined if the data type with a high grade is subjected to reference in the data type with a low grade(406-408). A loop for all data types in the second loop is formed again(410). If a data type in the formed loop exists in a range of the grade value of a compared data type(411), the grade value thereof is incremented by 1 and thereby the grade value of a next data type is adjusted(413). The aforementioned processes are performed for all data types of the first and second data types(414-416). It is checked if the adjustment for all data types are terminated(417).
