The importance of integrated management stems from the vision of merging telecommunications and distributed computing systems management within the same framework, rapid globalization of world enterprises, and the pressing need for networks and services to be more responsive to “end users.” This paper proposes an integrated and distributed management platform which is in line with, but not limited to, the integration of DME, OSI, TMN, and ODP principles. Furthermore, it focuses on a specific layer of the platform describing formally (i) the management domain and management policy concepts; (ii) the services which manage and enforce them; (iii) the performance policy enforcement service; and (iv) how to build-up policy hierarchies. In addition, this paper defines an Intelligent Multimedia Message Handling System (IM3HS) and depicts the high applicability of the domain and policy concepts to its management. Finally, an integrated management architecture for the IM3HS, as well as implementation issues of the IM3HS distributed management platform services are presented.

ADSL (Asymmetric Digital Subscriber Line) is a new key technology for offering broadband services to home users and small businesses. ADSL technology is ready to take off. Management discussions aim at achieving an ADSL broadband service architecture are still taking place, however. In order to support multiple services over widely spread networks incorporating various transmission techniques, a cost-effective network operation requires an end-to-end network management architecture. We describe here how to integrate ADSL equipment into the existing telecommunications management network. Alternative protocols and information models are also discussed. The overall network management architecture gives the motivation for the management concept applied to our Digital Subscriber Line Access Multiplexer (DSLAM). The design of such a network element covers all management functionality that is required to multiplex ATM connections being transferred over the ADSL system and to integrate the network element into any telecommunications network. We have chosen a flexible approach to adapt the DSLAM management to different usage environments.

The MANDAS project has defined a layered architecture for the management of distributed applications. In this paper we examine a vertical slice of this architecture, namely the management applications and services related to configuration management. We introduce an information model which captures the configuration information for distributed applications and discuss a repository service based on the model. We define a set of services and management applications to support maintenance of configuration information, and describe how the different types of configuration information are collected. Finally, we present two management applications that use configuration information.

Total Quality Management (TQM) is one of the most interesting and effective concepts of management. Although, as of today, it has been extensively applied to manufacturing and industrial sectors, TQM principles have not received wide acceptance in the area of Telecommunications Network and Service Management. Application of those principles in Telecommunications can be facilitated by employing pertinent techniques and tools. This paper focuses on aspects of the performance management of Telecommunications Networks and Services. As basic quality control mechanisms, two versions of a Dynamic Scaling Service (DSS) are used to regulate the end-user perceived quality: a Crisp DSS and a Fuzzy Logic DSS. A quality-oriented user behavior model is built and a comparative study between the different quality control schemes is presented. Concluding, the paper delineates the scope of TQM with respect to QoS management in telecommunications.

In this paper we consider wide-area backbone networks where multiple connection-oriented guaranteed services with differing bandwidth/flow requirements are offered. Specifically, we consider the case where each service requires a quality-of-service (QoS) peak rate bandwidth/flow allocation (different rate for different services) for the duration of the connection in a loss network environment. We present several dynamic routing schemes in such multi-service settings along with an admission control policy. The routing schemes cover issues such as crankback, periodicity of computation of routing, what type of information is to be used in routing decision, and whether to use centralized or decentralized computation. We present results for various measures, i.e., in addition to well-known call blocking performance, we also address and quantify measures such as signaling loads impact due to alternate routing, crankback impact, and revenue impact, and provide a comparative evaluation of various dynamic routing schemes in multi-service settings.

As service management systems are deployed in an open service market environment, the pressures on their developers to shorten development times and improve the flexibility of systems will increase. Component reuse may help in alleviating some of these pressures; however, while object-oriented reuse is used in the definition of interfaces for management systems, the systematic application of reuse to the systems’ internal design is not well established. This paper examines some of the approaches applicable to service management system development from the Telecommunications, Distributed Systems, Internet and Software Engineering fields. Experience in applying some of these approaches is presented, and based on this, refined approaches to service management system development are discussed.
