The advantages of avionics switched network in network scale and flexibility greatly improve the communication performance of avionics network, promote the development of IMA/DIMA technology and also increase network scale and complexity. Meanwhile, requirements for the management of the avionics system are also on the rise. In this paper, the characteristics of SNMP protocol and airborne switched...
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...
Since the cloud computing technology is commonly developed, some new inventions of the Internet are required to operate in hybrid architecture with both virtualized and physical components. To evaluate these kinds of innovations in testbeds, the ability of emulation is the key point. This paper presents a prototype design implemented in a network testbed for providing virtual nodes. By doing this,...
Network management system (NMS) is important to ensure security and efficiency of network. Traditional NMS usually adopts SNMP as management protocol and has achieved great success. However, with emerging of various services, traditional network exposes shortcomings. Software-Defined Network (SDN) is a new paradigm which separates the control plane from the forwarding plane as opposed to the distributed...
The application of SDN and OpenFlow in a production network will face the challenges of integration with legacy routers and legacy control and management protocols. Our contribution is to preserve distributed basic functions in legacy network devices and improve central control on complex functions with OpenFlow. This paper describes a refactoring process of an intra-AS source address validation from...
Network management system based on SNMP is a new way to manage the distributed photoelectric theodolites and their components. This paper presents the design of SNMP network management system by VC++ in Windows XP professional. Basic knowledge on network management and SNMP, SNMP architecture in Windows XP professional and program construction of network management system for theodolites and their...
Network resources monitoring and management is critical to ensure security and load balance of network and information system, especially in the increasingly extensively used cloud computing and distributed parallel architecture. This paper presents a distributed network resources monitoring solution based on multi-agent and matrix grammar. A distributed multi-agent architecture for network resources...
IPv6 over low-power wireless personal area networks (6LoWPAN), composed by large number of constrained devices with wireless communication ability, are becoming more and more important, not only because their reduced cost but also a lot of real world applications and their ability to connect to IP networks. Since devices in 6LoWPAN are expected to be deployed in extremely large numbers and they are...
This article analyzes network management system based on C/S and B/S architecture. Incorporating with advantages of two types of architecture, a design idea is brought up for building a network management system based on J2EE and RIA technology. Major common functions for network management system are designed and realized through research and analysis of data transmission mechanism among each layer...
When developing a network management system, the developer is faced with many choices concerning how to interact with the network resources and how to embed into the schema of manager agent architectures. In this paper we propose NMX (Network Management Extensions), a software framework implementation based on Java JMX (Java Management Extensions) technology and SNMP (Simple Network Management Protocol)...
SNMP (Simple Network Management Protocol) is a standard protocol for management of network devices. It provides excellent features, such as scalability, information management, authentication, encryption, and access control. However, SNMP has a structural weakness to fully support control functions for integrated management of digital convergence devices, and it has a limitation of message length...
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...
Service Oriented Computing (SOC) is the fast emerging successor of the Object Oriented Computing design paradigm. Web Services technology, which is considered as an implementation of the SOC model, has had an incredible acceptance but tumultuous growth. This apparent chaos is due to its inherent lack of flexible cooperation strategies, generic service model and weak semantic description, mainly when...
Traditional approaches to network management are mostly based on the centralized client/server model. Due to the intrinsic limitations of SNMP-based management paradigms, such as information bottlenecks and lack of flexibility, have encouraged a trend towards distributed management system. The emergence of mobile agent frameworks has led many researchers to examine their applicability to network management...
This article describes application of enterprise service Bus (ESB) architectural pattern implementation to integrate simple network management protocol (SNMP) with Java Management Extensions (JMX). The key goal is to enable managing JMX enabled applications using SNMP protocol and to demonstrate the features of Java Business Integration (JBI) integration platform. In the literature it is possible...
Power Line Communication (PLC) is an evolving technology which uses the existing power lines for data transmission. Like any other communication networks, PLC networks need to be managed for efficient use of resources and secure operations. Major PLC chipset and modem vendors are trying to provide network management solutions using SNMP by defining their own management information, but it is not sufficient...
With advancement in networking technologies and remarkable increase in the growth of IP networks, need of efficient management become essential part for network administrator. Without an intelligent, automated and self-learning management tool, it will become increasingly difficult to manage such a large network. Earlier techniques rely heavily on SNMP-MIB information or utilize ICMP-echo request/reply,...
