João Pires - Instituto de Telecomunicações / IST

Present and future of optical transport networks (download)

Abstract:

This talk will give an overview of the concepts and technologies that are behind today optical transport networks, and will discuss some evolution trends capable of keeping pace with the bandwidth needed for evolving applications.

Bio:

João J. O. Pires received the Ph.D. degree in Electrical and Computer Engineering from the Technical University of Lisbon in 1993. He is currently an Assistant Professor at Instituto Superior Técnico, where he has lectured on telecommunication networks and optical communication systems. From 1991 to 2000 he worked on a number of European-funded projects, including RACE and ACTS projects. He is the author or co-author of about 100 papers in international journals and conference proceedings. At present his research interests are mainly in the area of optical transport networks and optical broadband access networks.

Luís Coelho - CISCO

A Path for IP and Optical Integration (download)

Abstract:

If we take a look on the current Service Provider networks it will be very likely to find the IP and Optical layers working without any knowledge of each other. This fact leads to operational inefficiencies on the network which always mean extra cost to the Service Provider. This presentation proposes a path to a future converged transport network, where the IP and DWDM integration will be the foundation of a more efficient network, providing the Service Providers with more resources to overcome their day-to-day capacity challenges.

Bio:

Luís Coelho is currently working as Customer Solutions Architect for Service Provider Sales in Cisco Portugal. Since 1999 in Cisco, as a Systems Engineer Luís has also large experience with Public Sector, SMB, Enterprise and Finance customers. Cisco Certified Internetwork Expert in Routing and Switching and Service Provider technologies. Luís Graduated in Electrical Engineering and Computer Science and has a Post Graduation in Business Administration.

Raul Caldeira - ERICSSON

Software Defined Network - Evolution of Networks and its fiber impacts (download)

Abstract:

One of the bigger transformations advocated by the Telecom industry is the convergence with the IT and the scenario of virtualization. The Cloud-age is arriving to Networks and with it technical challenges and new network architectures must be defined to allow it. Ericsson will share its experiences on the definition of Software Defined Networks and its plans to build new architecture in the different layers, with it, covering aspects of Data transport optimization and Optical transmission impacts.

Bio:

Currently Customer Solutions Manager at Ericsson Portugal with the area of IP, Optical and Broadband Access, has more than 10 years' experience working on Optical Transport solutions. With a degree in Electric and Electronic Engineering from the Instituto Superior Tecnico, he worked in Siemens and Huawei Technologies, before joining is current position in Ericsson.

Gil Bento - ALCATEL-LUCENT

Optical transport networks evolution to OTN/DWDM (download)

Abstract:

Optical transport networks have been migrating from SDH technology to Wavelength Division Multiplexing (WDM) architectures over the past decade. Deploying WDM systems has allowed carriers to tap enormous capacity by carrying multiple wavelengths over a single fiber. As this transition to WDM architectures occurred, it became painfully obvious that early WDM implementations lacked many SDH key features required to properly operate and maintain these optical networks.

In 1998 the ITU-T standardized the OTN, a new optical transport standard that includes the benefits of SDH (such as resiliency and manageability) but with improvements for transporting high-rate data payloads. OTN was specifically designed to be multi-service transport container for any type of service from IP to SDH, and this is one of the technology's strongest value propositions.

Bio:

Gil Bento, engineer at Alcatel-lucent Portugal, have a Master Degree in Optoelectronics from the University of Paris Sud in France. He works in Alcatel-Lucent since 1999, first in France at the R&D branch for Submarine Transmission and then joined the subsidiary of Alcatel in Portugal in 2000. He was in charge of the design of the first terrestrial DWDM Link in Portugal between Lisbon and Porto in 2000 and also of the first 100G DWDM transmission in 2010. He's currently responsible for the design and support of Alcatel-Lucent Transmission solutions over optical fiber for Portugal.

José Palma - PORTUGAL TELECOM

Next Generation Optical Networks to support mobility, convergence and Cloud services (download)

Abstract:

The traffic growing in access networks, first with ADSL and then with FTTH, has been putting an increasing pressure in the core of network providers, in particular on the transport network. The introduction of 100 Gbps interfaces, is more than a need, it is seen as a solution that optimizes costs and responds to this data growth, and, nowadays, is a reality in the core and transport networks of several providers.

The next generation optical networks, using DWDM technology with ROADMs, with a GMPLS/ASON control plane, and promoting a closer proximity between the optical layer and the IP layer, stand as the only efficient solution in the transport network to respond to the data tsunami, giving support to mobility services, convergence services and Cloud services.

Bio:

José Palma is a senior networking engineer for Portugal Telecom, where he leads the Transport Networks Architecture and Strategy Unit. In his role he provides definition of architectures and strategic orientations for transport networks.

José Palma has accumulated more than 20 years engineering and telecommunications experience. He started his career in 1991 as Transmission Network Engineer for TLP- Telefones de Lisboa e Porto, SA. In 1994 José Palma integrated the unit responsible for the introduction of ATM technology in TLP. From 1995 to 1996 he served as PT's Operational Board Representative in the European ATM projects, MoU ATM and JAMES. In 1996 he was named Portugal Telecom ATM Network Operations Manager. In 2000 he joined PT Engineering Unit as Data Networks Manager. Since then he has been an active participant in the introduction of the new technologies in PT's Network, IP, ATM, ADSL, WIFI, Ethernet, MPLS, IPTV, and others.

José Palma holds a Degree in Systems and Computers Engineering from the Instituto Superior Técnico University (Lisbon).
