Past Projects

ARROWS (arrowsPoster.pdf)

Duration: 2001-2003
Partners: University Catalunha, Telefonica I+D, University Limerick, CSELT

This project aims to provide advanced Radio Resource Management (RRM) and Quality of Service (QoS) management solutions for the support of integrated voice and data services within the context of Universal Terrestrial Radio Access (UTRA). Both Time Division Duplex (TDD) and Frequency Division Multiplex (FDD) modes are considered. The project includes packet access, assymetrical traffic anf high bitrate (2Mbit/s) services for multimedia IP based aplications.

"LAB IP" (labipPoster.pdf) (labipPresentation.ppt)

This is a project internal to INESC Porto aimed to establish a live and evolving IP infrastructure that can be used by our researchers during the development and testing of their works. This infrastructure, that is based on Linux based PCs, is oriented towards the support of QoS, Mobility and Management aspects at the IP Access and Core networks. Integration with UMTS networks is also being addressed. Currently the Lab IP supports:

ATM, 802.3 and 802.11 interfaces.
an MPLS domain established over and ATM network;
traffic generators and detectors that are DiffServ capable;
mobile IP (v4);
VoIP experiement using a gateway for ISDN;

"UMTS Access Network Routing"

This project, directly contracted by Siemens, is aimed to propose and prove the feasability of a router for the UMTS access network.

"WINMAN - WDM and IP Network Management" (winmanPoster.pdf)

Duration: 2000 - 2002.
Partners: Lucent Tech. Nederland, Telefonica, Portugal Telecom, OTE Consulting, NTUA, University College of London, Universitat Politecnica de Catalunya, Rafael, Israel Aircraft Industries, Ellemedia Technologies, INESC Porto.

This project aims to develop a management system that can handle heterogeneous networks, in particular those which are related with IP and WDM.

"STAT" (statPoster.pdf)

Duration: 2000-2001
Partners: CDFTEL

This project aims to develop a test system (protocol analyser) and test suites for the tradicional TCP/IP stack.

"Schlumberger - Testing consultancy "

Duration: 1999 - 2000

This project consisted in providing consultancy to Schlumberger in three tecnhical areas: 1) ETSI V5 conformance tests; 2) access network elements production testing; 3) VoIP testing.

"NEC FA-1201 - V5 Digital Loop Carrier Transmission Equipment"

Duration: 1994 - 1999.
Partners: NEC Japan, NEC Brazil, INESC.

Descriçao

Trabalho de investigação que consiste na validação e teste de um sistema de telecomunicações para a rede pública de acesso. Esta rede, localizada entre as centrais de comutação digital e os equipamentos terminal, é usada para distribuição e gestão das facilidades de telecomunicações oferecidas pelas operadores aos seus assinantes. O sistema sob validação é um protótipo da NEC, o foi desenvolvido conjuntamente pela NEC do Japão, NEC do Brasil e INESC.

Validação

A validação deste protótipo consistiu em:

verificar a sua compatibilidade com as normas internacionais, através de testes de conformidade;
modelizar o desempenho e as falhas do sistema;
validar os modelos através da aplicação de testes ao protótipo ;
construir o equipamento necessário à boa execução dos testes.

Ferramentas Desenvolvolvida

Para execução dos testes foi desenvolvido o seguinte equipamento:

um emulador de central digital com 16 interfaces G.703 de 2Mbit/s e sinaliza,cao V5;
uma bateria de 600 equipamentos terminal (telefones analógicos e ISDN - acesso básico);
um compilador de testes que gera automáticamente testes de carga a partir das especificações funcionais das interfaces e dos objectivos de teste.
