Abstract

It is appropriate to use the NETCONF to monitor and manage today's complex networks that are composed of variety links and heterogeneous equipment. Since the first standard of the NETCONF are launched, there have been several revisions, but disadvantages of each layer capabilities is still present and the most typical disadvantage is XML document processing efficiency of the Content layer. In this paper, we perform data modeling by constructing a sub-tree based on the dependencies between Content layer data, and suggest method of extract efficiently data from XML by applying the extended VTD-XML technique for the XPath query. We performs experiment to compare NETCONF in proposed method to NETCONF in previous studies and NETCONF standard. we validate superiority of improved NETCONF in the paper. As experimental results, we verify that improved NETCONF is better than the other two NETCONF each 4% and 10% in terms of query processing rate, and faster than each 3.9 seconds and 10.4 seconds in terms of query processing speed.
