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.
