At present, network services have covered complex applications and value-added services, and service providers also need to consider service quality for customers' satisfaction. The equipment performance and faults directly affect the quality of service. Therefore, analyzing the relationship of service performance (the traffic distribution, transmission delay etc.), the network performance and faults...
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...
NETCONF, a new network management protocol, was released in 2006 which has overcome the weaknesses of SNMP. In the NETCONF protocol, it proposed a new mechanism subtree filtering, which allows an application to select particular XML subtrees. With the Subtree Filtering, specifically information of XML can be filtered out as a XML subtree. However, since the Subtree Filtering depends on the parsing...
The paper focuses on implementation of association pattern between the network performances and the general network faults. We use network simulation tool, OPNET, to accomplish network simulations of different network faults and different situations based on VoIP. Network performance parameters such as end-to-end delay, jitter, traffic dropped, queuing delay, link throughout, link utilization are...
NETCONF is a new network management protocol, based on the XML encoding method, which was proposed by IETF in 2006. It aims to overcome the shortcomings of SNMP predominantly used for configuration tasks at present. In the NETCONF protocol, subtree filtering mechanism and XPath capability is defined, both used to allow a client to select particular XML subtrees of the data model of the server. In...
In 2006, the IETF released its latest effort, NETCONF, a brand new network management protocol, which is based on the XML encoding method. The NETCONF protocol is thought to be able to meet the requirement of configuration management which SNMP fails to do well. The NETCONF protocol also performs better in other fields such as the efficiency, more flexible operations, etc. But, as a new protocol,...
As SNMP management system has some weaknesses due to its built-in functional limitation, NETCONF, with XML as its data encoding scheme, is viewed as a promising solution for future network configuration management. To make NETCONF interoperable and capable of manipulating data in a standardized fashion, an extensible data modeling language, YANG, was proposed to model data including configuration...
