An ICT-oriented Management Solution for NGNs

NGN architecture reused several standards from the IP world, as exemplified by the Session Initiation Protocol SIP, which is ubiquitous in the majority of these network components. However, the NGN management architecture simply presented a very generic management model that follows TMN. Several management technologies are proposed, such as Web services, CORBA and SNMP, to implement management solutions. Network and systems management standardizing bodies currently promote newer technologies that aim to solve known shortcomings to these. This paper proposes a management solution for NGNs based on recent IP world technologies. The presented solution was implemented in the form of a middleware to manage NGN elements. This middleware was used in the management of an element belonging to the IP Multimedia Subsystem platform, namely the Policy and Charging Rules Function

Role-based access control for xml enabled management gateways

Abstract. While security is often supported in standard management frameworks, it has been insufficiently approached in most deployment and research initiatives. In this paper we address the provisioning of a security "continuum" for management frameworks based on XML/SNMP gateways. We provide an in depth security extension of such a gateway using the Role Based Access Control paradigm and show how to integrate our approach within a broader XML-based management framework

An Adaptive Load-balancing Approach to XML-based Network Management using JPVM

SNMP is the most widely used network management protocol. Since SNMP is based on a centralized approach, it is confronted with scalability and efficiency problems when the network expands. XML-based network management is a new paradigm developed to overcome these limitations. In this paper, we propose a framework for adaptive load-balancing using JPVM for XML-based network management. The goal is to increase the efficiency of processing the management data, and decrease the communication time by distributing the management load across multiple XML/SNMP gateways. The load distribution among multiple gateways is adapted to achieve better results

Static Weighted Load-balancing for XML-based Network Management using JPVM

SNMP-based network management is simple but lacks scalability and efficiency of processing the management data as the number of agents increases. XML-based network management is a new paradigm developed to overcome these limitations. One of the main challenges is how to distribute the management tasks to achieve efficiency and scalability. In this paper, we propose a framework using JPVM to distribute the management tasks among multiple gateways. We compare the performance of three approaches, namely the static weighted load balancing approach, the equal work non-weighted load balancing approach, and the single gateway approach. The first approach provides better communication time between the XML-based manager and the SNMP agents. It takes advantage of the XML, DOM, and Java servlets
