Today’s enterprise networks are composed of multiple types of interconnected networks. Furthermore, organizations use a variety of systems and applications on these networks. Operations and management staff must provide an efficient, reliable and secure operating environment to support an organization’s daily activities. Enterprise networks must be monitored for performance, configuration, security, accounting and fault management. Current management practices typically involve the use of complex, hard-to-learn and hard-to-use tools. What is needed desperately is a set of simple, uniform, ubiquitous tools for managing networks. Web-based management promises to provide such solutions. This paper focuses on the use of Web technology and the Multi-Router Traffic Grapher (MRTG) for the purposes of enterprise network traffic monitoring and reporting. In this paper, we first examine the requirements for enterprise network traffic monitoring, analysis and reporting, and then present the design and implementation of a Web-based network traffic monitoring and reporting system that satisfies those requirements. We also present guidelines we have formulated and used for analyzing enterprise network traffic. We then discuss our experiences in using such a system for traffic monitoring on two large enterprise networks.

The use of Virtual Private Networks (VPNs) is one of the major trends in the integrated broadband communications environment. Currently, the control and management of VPN resources is mainly supported by the provider of the bearer telecommunication services, and VPN customers have no control over these resources. The increasing importance of the broadband communication infrastructure in corporate operations and transactions is stressing the requirement for a customizable configuration, operation and management of VPN services. First, this paper discusses the evolution of VPN environments towards customized VPN configurations and goal-driven management of these VPNs. VPN service characteristics and management requirements are analyzed. Then, the paper introduces the proposed customer management architecture satisfying these requirements. The architecture is based on the multi-level virtualization of network resources through the partitioning of resources in the provider’s shared communication infrastructure and the dynamic allocation of these resources to customers. A Web-based distributed approach is used for implementing the proposed customer management of VPNs.

This paper describes an architecture for management services. The architecture consists of a number of small components, each performing a highly specialized task. Together, they form a dynamic, highly automated, yet integrated management system. The components are plug-and-play services that use Jini to dynamically establish communication links among themselves and form transient management federations. Our architecture is built around a configuration service which provides for consistent configuration of managed resources. We identify a number of common management scenarios and demonstrate how they can be supported by our system.

Web-based network element management provides an administrator with the ability to configure and monitor network devices over the Internet using a Web browser. The most direct way to accomplish this is to embed a Web server [Embedded Web Server (EWS)] into a network device, and use that server to provide a Web-based management user interface constructed with HTML, graphics, Java and other features common to Web browsers. In this paper we present EWS-based management application interface mechanisms for use between embedded management applications and embedded Web servers. We propose a guideline for choosing an efficient interface mechanism, which is based on the characteristics of management information and Web documents. A Web-based management user interface through embedded Web servers has many advantages such as ubiquity, platform independence and user-friendliness. In order to be truly useful, a Web-based management user interface must have a low development cost and a short development time. We provide effective integration mechanisms for each interface. We validate these mechanisms by implementing them in an Internet router.

Mobility, tightening competition and changes in system administrator behavior present new challenges in the management world. In particular, the need to constantly monitor services and rapidly identify and fix problems is becoming increasingly important. The Internet has made it possible to offer a comprehensive range of management services and applications accessible over the web. Nevertheless, in the near future a new and improved way to manage systems will be done by means of mobile phones. This paper shows how existing web-based solutions can be enhanced to support the new generation of media phones based on WAP (Wireless Application Protocol) technology. Although the specific focus of this work is on management solutions, the rsults are general and applicable to many other types of existing web-based applications. Some implementation details and experiences drawn from adding a WAP interface to an existing web-based management application are described.
