BGP control mechanism has been offered to be engaged with the existing inter-domain routing protocol (BGP) to be able to fulfill and manage the internet scalability demands of bandwidth, services, applications, technologies and off course users.
This work focuses on the further reduction of the bandwidth usage of the Bloom Filter based SNMP by means of an additional compression scheme. The zip compression technique is used for the zip encryption and the zip decryption of the Bloom Filter. The experiment with compression ratio was done and the results show that the SNMP bandwidth that utilizes the proposed compression scheme is reduced to...
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...
Current management models based on client/server suffer from scalability and flexibility problems. Furthermore, the staleness of gathered data (due to network latency involved) and probable error in the selection of management task being carried over (owing to the staleness of data) reduces the reliability of the management applications. In this sense, use of mobile agents offer many possibilities...
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,...
This paper proposes a simple and low cost implementation framework for a policy-based network management (PBNM) system. The framework consists of reusing traditional network management system resources, specifying network management policies through the database language SQL, and designing a management database. It supports automatic network management policy processing. Finally, we used a simple...
With the continuous expansion of the network scale, the complexity and heterogeneity of computer networks request high toward network management. While a SNMP-based centralized network management has disadvantage in the scalability and flexibility. By applying mobile agent is a good solution to those problems. In this paper, a mobile agent-based distributed network management framework is presented...
Nowadays Internet become more and more important in our life maintenance, the security of network was put into an important place. The valid data of the network traffic monitor not only enables network administrators to obtain the most direct information of the network movement in time; at the same time, completes the supervision of the traffic, and is also a necessary method of network management...
More than a decade ago, MA(mobile agents) were introduced for NM(network management) of distributed computer networks in tandem with the design paradigm of code-shipping the agents to remote node, where they are programmed to collect, analyze and process data locally. However, even today, most networks employ SNMP (simple network management protocol), an inherently client-server based stable and proven...
During the last decade several network management solutions have been proposed or extended to cope with the growing complexity of networks, systems and services. Architectures, protocols, and information models have been proposed as a way to better respond to the new and different demands of global networks. However this offer also leads to a growing complexity of management solutions and to an increase...
As wireless mesh networks become more popular, there exists a need to provide centralized management solutions, which facilitate network administrators to control, troubleshoot and collect statistics from their networks. Managing wireless mesh networks poses unique challenges due to limited bandwidth resources and dynamic channel quality. A robust management solution should function despite network...
WiMAX features several QoS service classes to schedule different types of traffic. In this paper, we will assess the existence of self-similar traffic for each service class. The experiment starts by capturing the traffic data with a dedicated SNMP-based network management system (NMS). NMS manages the deployment of fixed WiMAX network defined in IEEE 802.16d-2004 Standard and records the inbound...
As a system for guaranteeing Quality of Service of continuous media by traffic control, there exists Integrated Services using Resource ReSerVation Protocol that guarantees bandwidth for object traffics by executing bandwidth control. This system, however, restricts bandwidth for other traffics through the session of object traffics because of its static bandwidth control. Then, to solve the problem,...
SNMP, SNMPv2 and SNMPv3 are the standard protocols for network management in traditional wired networks. New RFCs have updated SNMP, but it remains focused on high-availability, high-bandwidth networks. In the dynamic MANET of tactical edge networks, fast-moving aircraft and terrain obscuration combine to create conditions where traditional SNMP is less effective. In this paper, we propose innovative...
This paper compares the performance of Web services based network monitoring to traditional, SNMP based, monitoring. The study focuses on the ifTable, and investigates performance as function of the number of retrieved objects. The following aspects are examined: bandwidth usage, CPU time, memory consumption and round trip delay. For our study several prototypes of Web services based agents were implemented;...
The composition of the network becomes more complex and the number of nodes that compose a network has increased greatly. Therefore, efficient network management is becoming vital. SNMP (Simple Network Management Protocol) with its advantages of high efficiency has been widely used in the management of a variety of network communication equipments, but how effectively transmit large bulk data between...
