Following the success of CORBA based systems the OMG has standardized the CORBA Component Model (CCM) to improve the implementation process of large distributed systems. The European project COACH [16] has been set up to build an Open Source development platform to construct CCM applications. As part of COACH a toolset for CCM components and system testing(More)
Traditionally, policy management has been mainly restricted to the Internet protocol (IP) domain. However, policy management principles can be applied to all management layers and to several technology domains. In close cooperation with several network operators, Lucent investigated policy management requirements for, and implemented policy management(More)
The next generation of communication networks is expected to create a heterogeneous network environment encompassing an ever-increasing number of different access networks and end-user terminals that will enable the introduction of and provide access to numerous feature-rich end-user services. It is essential that end users be able to roam from one access(More)
In this paper we present a framework for testing software systems that is based on the Common Object Request Broker Architecture (CORBA*) component model (CCM) standard. An important aspect of CCM-based systems is that they must be verifiable and testable at the abstract level of their design, regardless of the language chosen to implement the component.(More)
The management of heterogeneous and hybrid networks has been always a challenge for network operators. Different frameworks and architectural approaches have been proposed and investigated in the literature. The purpose of this paper is to present the evaluation results of an integrated network management solution for the provisioning and maintenance of IP(More)

In today's network, several transport technologies have to be managed to work in close conjunction. Until recently, service providers needed separate, single-vendor solutions or interfaces to manage these different technology areas. This letter proposes an integrated transport network management solution of domain-specific and inter-domain network(More)
