Traditional network management approach involves the management of each vendor's equipment and network segment in isolation through its own proprietary element management system. It is necessary to set up a new network management architecture that calls for operation consolidation across vendor and technology boundaries. In this paper,an architectural model for Intelligent network management (INM) is presented. The INM system includes a manager system, which controls all subsystems and coordinates different management tasks; an expert system, which is responsible for handling particularly difficult problems, and intelligent agents, which bring the management closer to applications and user requirements by spreading intelligent agents through network segments or domain. In the expert system model proposed, especially an intelligent fault management system is given. The architectural model is to build the INM system to meet the need of managing modern network systems.

The healthcare sector holds valuable and sensitive data.The amount of this data and the need to handle,exchange,and protect it,has been increasing at a fast pace.Due to their nature,software-defined networks(SDNs)are widely used in healthcare systems,as they ensure effective resource utilization,safety,great network management,and monitoring.In this sector,due to the value of thedata,SDNs faceamajor challengeposed byawide range of attacks,such as distributed denial of service(DDoS)and probe attacks.These attacks reduce network performance,causing the degradation of different key performance indicators(KPIs)or,in the worst cases,a network failure which can threaten human lives.This can be significant,especially with the current expansion of portable healthcare that supports mobile and wireless devices for what is called mobile health,or m-health.In this study,we examine the effectiveness of using SDNs for defense against DDoS,as well as their effects on different network KPIs under various scenarios.We propose a threshold-based DDoS classifier(TBDC)technique to classify DDoS attacks in healthcare SDNs,aiming to block traffic considered a hazard in the form of a DDoS attack.We then evaluate the accuracy and performance of the proposed TBDC approach.Our technique shows outstanding performance,increasing the mean throughput by 190.3%,reducing the mean delay by 95%,and reducing packet loss by 99.7%relative to normal,with DDoS attack traffic.

An emulating environment for network management of the space network was presented. The emulating environment was developed with node-link model. The nodes of the satellite entities were controlled by the controlling network, which consist of sets of HLA/RTI based federates. These federates described the different aspect of the attributes of the satellites, such as orbit coordinate, routing table and the chain budget. We described the architecture of the emulation environment and the software design of federates. We measured the response time of the protocol data units and verified the detecting of the network topology in the environment. The environment was open that the on board router and the simulator of satellite link which developed by third party could be integrated.

Owing to the increasing great complexity, computer network systems requiremore sophisticated management strategies to be adopted so as to guarantee adequate levels ofperformance. The classic centralized paradigm, adopted by SNMP, which was once appropriate in theprevenient phrase, has posed problems with the explosive expansion of networks, as well as othercentralized models. Mobile Agent (MA), owing to its capability of implementing a distributed system,represents a challenging approach to provide network management with high performance. In thispaper we analyze the network management structure model based on MA at first, and then we putforward a reference scenario based on MA and compare it with the traditional model. We also describea prototype implementation based on our mobile agent system named MAS. Finally, we do someexperiments to verify the performance of our framework prototype.

Security of mobile-agent based network management must be considered due to the widespread adoption of mo-bile agents in network management,which involves the protections of mobile agents,management station and managed de-vices.The integrated security model proposed in our paper incorporates the effective security countermeasures of these entitiesinto a trusted execution environment and two security protection layers.Sandbox based on Java virtual machine and Javacard independent on the network devices also with the cryptography technology in this model together protect the networkmanagement process.

With the development of computer network, the SNMP network management model has not been able to meet the requirement. A new kind of management system and strategy must be provided to enhance the reliability and performance of the network management. This paper discusses the issue which exists in the tradition network management, and analyzes the active network management system structure and the management mechanism. We propose a new kind of active network management model based on mobile Agent, analyze this network management system structure and the management mechanism.

IP Multimedia Subsystems （IMS） is considered as a comprehensive approach for full-service operation. However, traditional network management concepts are not applicable to IMS network management. This is because IMS is characterized by a flat, all-IP architecture, simplified functionality of network Elements （NE）, and a variety of NEs, This paper introduces an IMS network management system design that covers full-service operation. It then discusses the significant role IMS network management plays in the unification of NE management layers, the increasing importance of end-to-end applications, and the convergence of Enhanced Telecom Operation Map （eTOM） and IT Infrastructure Library （ITIL）.

To improve the scalability of RMON-based network management, the concept of Mobile RMON Agent (MRA) was presented by combining the mobile agent technology with RMON. Then an MRA-based network management System (MRANMS) was designed and implemented. RMON functions were achieved by programming the mobile agent to make it capture and analyze packets locally. The experimental result on the Grasshopper platform indicates that MRA as a mobile agent can migrate to another subnet and calculate a RMON MIB value and TrafficMatrix in a subnet with 29 hosts. Furthermore, the behavior of MRA can be customized to achieve new RMON functions, such as the statistics of hostTable in RMON MIB. It can be concluded that MRANMS is based on the mode of distribution, and besides the compatibility with standard RMON, the system possesses scalability of management function.
