Proceedings JENC6 M. R. Siegl HIERARCHICAL NETWORK MANAGEMENT A Concept and its Prototype in SNMPv2 Manfred R. Siegl Georg Trausmuth Abstract The increasing size of networks makes their management more and more di cult. While large networks are already structured hierarchically in two or three layers, network management has not yet moved from at...

XML has been applied to numerous information processing application areas for various objectives and has earned excellent reputation for simplicity, extensibility, and openness. Researchers and developers in the network and system management area have begun to investigate the use of XML technologies in order to solve the problems that exist in Internet management standards such as SNMP. However...

In the management world, the web is considered by many people the best user interface for next generation management systems. This is because the use of the web has several benefits with respect to non web-based management applications such as: • Web browsers are provided with almost every OS. • Hypertext facilities can be profitably used for on-line help and documentation. • Web pages can inte...

The continuous growth in scale and diversity of computer networks and network components has made network management one of the most challenging issues facing network administrators. It has become impossible to carry out network management functions without the support of automated tools and applications. In this chapter, the major network management issues, including network management require...

Today’s wireless networks are highly heterogeneous, with mobile devices consisting of multiple wireless network interfaces (WNICs). Since battery lifetime is limited, power management of the interfaces has become essential. We develop an integrated approach for the management of power and performance of mobile devices in heterogeneous wireless environments. Our policy decides which WNIC to empl...

The purposes of this paper have to discuss issues related to Network Traffic Management. A relatively new category of network management is fast becoming a necessity in converged business Networks. Mid-sized and large organizations are finding they must control network traffic behavior to assure that their strategic applications always get the resources they need to perform optimally. Controlli...

As the world’s communication needs increase, telecommunications providers are building larger and more complex networks to meet this demand. These evolving networks will often contain many technologies, and while most modern networks are still single-vendor, many companies are looking to diversify their networks. While on-the-wire interoperability is clearly defined by various standards bodies,...

We introduce the architecture, object model, components, and protocols of a management overlay for federated service management, called Web Services Management Network (WSMN). WSMN targets management of web services that interact across administrative domains, and therefore typically involves multiple stakeholders (examples are business-to-business, service provider interconnections, help desks...

Configuring a network is a tedious and error-prone task. In particular, configuring routing policies for a network is complex as it involves subtle dependencies in multiple routers across the network. Misconfigurations are common and certain misconfigurations can bring the Internet down. In 2005, a misconfigured router in AS 9121 blackholed traffic for tens of thousands of networks in the Inter...

The ubiquity and complexity of modern networks require automated management and control. With increases in scale, automated solutions based on simple data access models such as SNMP will give way to more distributed and algorithmic techniques. This article outlines present and near-term solutions based on the ideas of active networks and mobile agents, which permit sophisticated programmable co...
