This paper focuses on research device management mechanisms such as routers and switches, based on the NETCONF protocol, considered user authentication mechanisms using RADIUS-server and implementation of these mechanisms in currently being developed Eltex Network OS. Reflected the main features of NETCONF protocol — Network Configuration Protocol, produced theoretical and experimental comparison...
Different architectures of interactions between the objects in the Internet of Things have been proposed, based on direct exchange of data between the wireless devices or based on synchronization with fixed network devices or cloud infrastructure. We evaluated how the selection of the communication architecture influences the performance of the data exchange using discrete event simulation. The distribution...
The Hard Real-Time Ethernet Switch (HaRTES) allows using the same network to handle multiple traffic flows, without compromising the performance of real-time applications. Furthermore, it also provides flexible and on-line scheduling techniques with admission control capabilities, thus real-time communications flows can be added, removed and updated online with strict temporal isolation. However,...
Traditional SNMP network management protocol can not meet the configuration requirements of modern complex networks. IETF Organization has developed the NETCONF XML-based network configuration management protocol, and it is imminent how to develop a new network management system to both support SNMP network devices and NETCONF devices. It is critical that we call the SNMP Bean or NETCNONF Bean by...
This paper presents an overview and empirical study of NETCONF, which is a new network management protocol approved by IETF in December 2006. The traditional approaches of CLI, SNMP, and CORBA are discussed, along with their deficiencies in network management. In this paper we present an empirical study based on a standard NETCONF implementation. We highlight the major capabilities of NETCONF, which...
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...
As networks become more and more heterogeneous, SNMP can not meet current management requirements for complex networks, especially those configuration management needs. NETCONF protocol is a next generation configuration protocol developed by IETF organization. In this paper, in the full considerations for architectures of NETCONF Agent we explicate the details of NETCONF protocol 'implements, especially...
In the paper, we describe a "plug-and-play" configuration of nodes of a tactical network on the basis of XML configuration templates and a network plan, developed during the network planning process. We present the concept of a configuration repository, an XML-based database that stores network structure and configuration data, and describe how the Simple Network Management Protocol is used...
This paper addresses the consistency of heterogeneous device access control in the network management area. It addresses well-know network management frameworks like SNMP (v3), CLI, Netconf and the lesser known TR-069 proposed in the framework of ADSL operators. For each of these, a formal definition of the access control model is proposed as well as the conversion towards a unified Role-Based Access...
As the Internet continues to grow, the tasks of configuration management for IP network devices are becoming more and more difficult. Over the past few years, much effort has been given to improve the deficiency of SNMP in the configuration management scope, but only few have succeeded to be standardized, the famous one of which is Netconf, developed by the IETF. Even the Netconf is still far from...
