Network monitoring system plays an important role in ensuring network security and maintaining network stability. Based on the thorough study of the application of the simple network management protocol (SNMP), a network intelligent monitoring model for test internet protocol (IP) network is designed, and a network monitoring system is developed. The system can realize the network equipment operation...
A network topology algorithm based on SNMP was put forward and implemented. This algorithm could confirm the connection between ports and improve the efficiency of discovery through combining the topology discovery of the network layer and the link layer. It could solve the problem of subnet information redundancy and incomplete information of address forwarding table during the discovery. The experimental...
In presented paper we describe a design and implementation of an information system based on base of embedded client and Linux application server architecture. Presented information system serves for remote collection, storing and processing information on the number of carried out mechanical cycles for group of older existing fatigue test machines in an automotive components production. This upgrade...
In today's digital era with the development of various types of gadgets causes the growth of traffic and the number of internet service on the network. To provide the maximum monitoring system that can determine service availability, network conditions, uptime and downtime. Protocol monitoring system used in this research is the Simple Network Management Protocol (SNMP). Due to the use of SNMP protocol...
The single chip microcontroller units (MCU) are widely applied in various embedded systems combined with different function type of sensors, robots, hybrid vehicle, or communication interfaces to control circuits. Usually single chip MCU system is triggered via the input voltage to affect the internal program logic, and then, the output state is changed. Simple Network Management Protocol (SNMP) is...
In this paper, we propose an autonomic network management system that analyzes, evaluates, and optimizes the redundancy of routes providing access to remote sites from a local area network. The proposed solution ARRC is based on SNMP as simple network management protocol to monitor the gateways, analyze their layer 3 operations and perform an extra configuration that enhances the availability of network...
Nowadays, many researchers are interested in the concept of Internet of Things (IoT). IoT is evolving our knowledge and conception of the world. IoT aims to offer a common communication paradigm for all objects via the Internet and its protocols. For that reasons, it is being applied in all areas of life, such as environmental monitoring, healthcare, military, cities management, and industry. One...
Communications systems fielded by US-DoD and commercial organizations are often highly customized by individual programs and vendors. These systems are typically integrated into larger individual (system-of-systems) platforms one platform at a time. While such systems perform very well for their designed use, many do not consider enterprise requirements such as scalability, and aggregation of control...
The enlargement of the current enterprise network scale makes the conflict between application systems and network devices inevitable. To address this issue, this paper proposed a verification method of network reach ability based on topology path. Our approach extracts communication need of application systems through formalization method, so the problem of whether the communication need will be...
Industrial communication networks become more complex and real-time networking protocols primarily developed for them become more common in our daily lives as technology evolves. As a result of this, topology discovery and diagnostic mechanisms developed for industrial communication networks come into prominence. One of the most well-known industrial communication networks, PROFINET is the basis of...
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...
Substation automation using IEC61850 (IEC61850 SA) now is widely implemented by many power utilities around the world. Currently, communication architecture of IEC61850 SA is based on Ethernet and TCP/IP technology. Thus, the SA network consists of computers, Ethernet switches and many various IEDs such as protection relays and bay controls units (BCUs). The performance of most SA functions relies...
ARP spoofing is a deception within the LAN caused by ARP protocol flaws, which could cause the whole network paralyzed and even worse users' important information stolen through spoofing. The features of ARP is introduced in detail, the update mechanism of ARP mapping table is summarized by ARP spoofing simulation experiment, and the process of ARP spoofing is analyzed. An effective solution which...
Network performance management need to monitor, analyze and record several of performance indexes in order to find out the switch happens or potential danger. This paper briefly introduced the goals of network performance management and basic functions, and network performance analysis based on SNMP including the port status analysis, port flow analysis and equipment resources utilization analysis,...
It is very tedious and trivial if a network administrator has to manage all the equipment manually. Unfortunately, there are usually numerous and heterogeneous devices over which an administrator must watch. This paper proposes the design and development of an automatic event-driven system to reduce the burden on network administrators. By allowing managers to pre-define the action of some conditions,...
Wireless sensor networks (WSNs) have received lots of attention in recent years. WSNs have been applied to multiple fields such as video surveillance, home automation, and health care. How to efficiently manage WSN devices thus becomes an important issue. Simple Network Management Protocol (SNMP) is an IP-based network management protocol which can collect and modify management information from network...
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...
As the foundation of network management technology, Network topology has been always the research hotspot which reflects the basic characteristic of a network, so from its topology, you can figure out the bottleneck and hidden security problems of a network easily and quickly. The technology of network topology visualization is such a technique that it researches on network topology by discovering,...
Time slot and wavelength switching have increasing role in IP networks due to their ability to switch high speed data flows in simpler and more economical and energy efficient way than packet switching. The introduction of GMPLS directly integrates IP layer with underlying time slot and wavelength switched layers, whose most important representative is OTN layer. This paper describes one solution...
Knowledge of the physical topology of an IP network is crucial to a number of network management tasks, including reactive and proactive resource management, root-cause analysis, and event correlation. Given the dynamic nature of IP networks, keeping track of network topology information manually is a daunting task. So, effective algorithms for automatically discovering physical topology of an IP...
