The comparison and analysis of tree data model and table-like data model based on NETCONF

NETCONF is a new standard network configuration protocol. For further research we have developed an open experimental platform for NETCONF protocol, BUPT-NEP (BUPT NETCONF Experimental Platform). Moreover, based on the experimental platform some significant technologies, such as data filtering, data storage and so on, are considered. This paper gives a detailed introduction of the tree data model and the table-like data model, which both could be used to organize and store the network facilities´ information, and highlights the comparison of them in two aspects of the space occupancy as well as the filtering performance. From the comparison results it comes to a conclusion that the table-like data model could keep more information; however, the tree data model is easy to understand and shows better filtering performance.
