Intelligent Integrated Management for Telecommunication Networks

As the size of communication networks keeps on growing, faster connections, cooperating technologies and the divergence of equipment and data communications, the management of the resulting networks gets additional important and time-critical. More advanced tools are needed to support this activity. In this article we describe the design and implementation of a management platform using Artificial Intelligent reasoning technique. For this goal we make use of an expert system. This study focuses on an intelligent framework and a language for formalizing knowledge management descriptions and combining them with existing OSI management model. We propose a new paradigm where the intelligent network management is integrated into the conceptual repository of management information called Managed Information Base (MIB). This paper outlines the development of an expert system prototype based in our propose GDMO+ standard and describes the most important facets, advantages and drawbacks that were found after prototyping our proposal

SIT automation tool: failure use case automation and diagnosis

Study of systems to manage the performance and quality of service of wireless data networks. Work with optimization techniques and project management to solve complex networks issues.The scope of this thesis is the SIT (System Integration Testing) process which is the testing procedure executed in customer test environment before the software goes on production environment. The main objective for this thesis is no other than improving the current process step by step taking into account the automation, efficiency, missing checks and much more. This project is a kind of Industrial process to create a powerful testing tool which can allow the company to deliver quality adaptor products efficiently, do better in less time helping to reduce costs, as Adaptors are the most demanded product of MYCOM OSI portfolio. Take into account that business is not only generated when an Adaptor is delivered for first time but also when Vendors provide with new releases and new functionalities and operators needs to order an upgrade of the Adaptor to be able to monitor the new functionalities deployed on their network.El campo de aplicación en el que está centrado esta tesis es el SIT (System Integration Testing), proceso de testeo ejecutado en un servidor de testeo del cliente antes de desplegar el software el medio de producción. El objetivo principal de esta tesis no es otro que mejorar el proceso actual paso a paso teniendo en cuenta la automatización, eficiencia, la falta de verificaciones, entre otros. Este proyecto es una especie de proceso industrial para crear una aplicación potente de testeo que pueda permitir a la compañía entregar adaptadores de calidad con eficiencia, que hagan más en menos tiempo ayudando así a reducir costes. Los adaptadores son el producto más demandado del porfolio de MYCOM OSI. Hay que tener en cuenta que el negocio no se genera solamente cuando se entrega por primera vez el adaptador al cliente, sino que cuando los proveedores lanzan nuevas versiones con nuevas funcionalidades y los operadores necesitan encargar una mejora del adaptador para poder monitorizar las nuevas funcionalidades desplegadas en su red.El camp d'aplicació en que es basa aquesta tesi és el SIT (System Integration Testing), procés de testeig executat en un servidor de testeig del client abans de desplegar el software al mitjà de producció.

The battle between standards: TCP/IP vs OSI victory through path dependency or by quality?

Between the end of the 1970s and 1994 a fierce competition existed between two possible standards, TCP/IP and OSI, to solve the problem of interoperability of computer networks. Around 1994 it became evident that TCP/IP and not OSI had become the dominant standard. We specifically deal with the question whether the current dominance of the TCP/IP standard is the result of third degree path dependency or of choices based on assessments of it being technical-economically superior to the OSI standard and protocols

Deep Space Network information system architecture study

The purpose of this article is to describe an architecture for the Deep Space Network (DSN) information system in the years 2000-2010 and to provide guidelines for its evolution during the 1990s. The study scope is defined to be from the front-end areas at the antennas to the end users (spacecraft teams, principal investigators, archival storage systems, and non-NASA partners). The architectural vision provides guidance for major DSN implementation efforts during the next decade. A strong motivation for the study is an expected dramatic improvement in information-systems technologies, such as the following: computer processing, automation technology (including knowledge-based systems), networking and data transport, software and hardware engineering, and human-interface technology. The proposed Ground Information System has the following major features: unified architecture from the front-end area to the end user; open-systems standards to achieve interoperability; DSN production of level 0 data; delivery of level 0 data from the Deep Space Communications Complex, if desired; dedicated telemetry processors for each receiver; security against unauthorized access and errors; and highly automated monitor and control

A Structured Hardware/Software Architecture for Embedded Sensor Nodes

Owing to the limited requirement for sensor processing in early networked sensor nodes, embedded software was generally built around the communication stack. Modern sensor nodes have evolved to contain significant on-board functionality in addition to communications, including sensor processing, energy management, actuation and locationing. The embedded software for this functionality, however, is often implemented in the application layer of the communications stack, resulting in an unstructured, top-heavy and complex stack. In this paper, we propose an embedded system architecture to formally specify multiple interfaces on a sensor node. This architecture differs from existing solutions by providing a sensor node with multiple stacks (each stack implements a separate node function), all linked by a shared application layer. This establishes a structured platform for the formal design, specification and implementation of modern sensor and wireless sensor nodes. We describe a practical prototype of an intelligent sensing, energy-aware, sensor node that has been developed using this architecture, implementing stacks for communications, sensing and energy management. The structure and operation of the intelligent sensing and energy management stacks are described in detail. The proposed architecture promotes structured and modular design, allowing for efficient code reuse and being suitable for future generations of sensor nodes featuring interchangeable components

Multimedia Teleservices Modelled with the OSI Application Layer Structure

This paper looks into the communications capabilities that are required by distributed multimedia applications to achieve relation preserving information exchange. These capabilities are derived by analyzing the notion of information exchange and are embodied in communications functionalities. To emphasize the importance of the users' view, a top-down approach is applied. The (revised) OSI Application Layer Structure (OSI-ALS) is used to model the communications functionalities and to develop an architecture for composition of multimedia services with these functionalities. This work may therefore be considered an exercise to evaluate the suitability of OSI-ALS for composition of multimedia teleservices

Performance study of voice over frame relay : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Information Engineering, Massey University, Albany, New Zealand

Frame Relay (FR) represents an important paradigm shift in modern telecommunication. This technology is beginning to evolve from data only application to broad spectrum of multimedia users and potential to provide end users with cost effective transport of voice traffic for intra office communication. In this project the recent development in voice communication over Frame relay is investigated. Simulations were carried out using OPNET, a powerful simulation software. Following the simulation model, a practical design of the LAN-to-LAN connectivity experiment was also done in the Net Lab. From the results of the simulation, Performance measures such as delay, jitter, and throughput are reported. It is evident from the results that real-time voice or video across a frame relay network can provide acceptable performance
