Plataforma Avançada Integrada de Serveis



PAIS project develops and deploys an optical testbed facility that will available to the Catalan ICT sector to validate next-generation optical equipment and services.

One of the PAIS project objectives is the design and implementation of an optical multiplexing node based on ROADM technology (and Reconfigurable Optical Add Drop Multiplexer) with carrier-class specifications. The transport network is deployed in Barcelona Metropolitan Area, with nodes at i2CAT (Campus Nord), the Municipal Institute of Informatics (IMI, [email protected]) and Orange Catalunya (Pedrosa-L'Hospitalet de Llobregat ).

Another key activity of the project is to validate a FTTH (Fiber-to-the-Home) platform. This validation is done in BAMPLA group laboratory in Castelldefels and in Bufalvent industrial park, near Manresa, which is connected to the testbed. This network extension tests and validate FTTH services aligned with the requirements of the Future Internet.

This project is cofounded by European Regional Development Fund, in the framework of Programa Operatiu Objectiu 2 de Competitivitat Regional i Ocupació de Catalunya ERDF 2007-2013.



The PAIS project extends the hardware and software functionalities of the reconfigurable optical nodes developed during the DREAMS project (2007 CIDEM Profit 2007/2008), adding the following features:

  • QoS measurement of the optical transport signal with extraction of digital signal performance monitoring (GbE, SDH or UTO).
  • OTU-1 (2.5 Gbps) and OTU-2 (10 Gbps) signal encapsulation before backbone input.
  • Aggregation-disaggregation of GbE channels in the electrical domain (using GFP, VCAT techniques) and OTU-2 signal encapsulation resulting from the aggregation.
  • Adding the new functionalities to the NMS system (Network Management System).
  • Extension of current LCT (Local Craft Terminal) system functionality to a local console.
  • Provide 1+1 redundancy to SNMP monitoring modules of the racks.
  • Provide 10G transponders / muxponders with embedded tuning capabilities to provision any DWDM 100GHz grid C-band wavelength.
  • Extension of the interface between the optical hardware node and the optical connections handler to report changes of resources and optical connections.
  • Definition of methods and procedures specifying how and when to add, disseminate, and use this information. Improvement of OSPF-TE routing Protocol.
  • Design of distributed routing algorithms for provisioning and / or protection, considering physical layer parameters across the network.
  • Factorization and modularization of the implementation of the OSPF-TE routing protocol to incorporate a simple and non-disruptive new routing algorithm.
  • Development of a tool for planning and re-optimization of high-capacity DWDM optical transport networks with dynamic traffic, optical switching, and insertion-extraction of optical carriers.
  • Improving the stability of the management and operation tool, integrating new hardware and software capabilities developed under the project.
  • Development of a FTTH GPON solution for industrial areas maximizing the quality of service for traditional services (POTS, data, etc..) and the bandwidth to allow the provision of advanced telecommunications services.

One of the main objectives of PAIS is to provide a connectivity service to a next-generation optical network facility, with high transmission capabilities to validate new technologies and network devices. To fulfil these objectives and the deployment of infrastructure, a software tool that allows configuring the whole platform have been implemented.

The implementation of the PAIS project enables companies to access to specific validation resources on demand without having to invest in the deployment of a testing facility to validate their developments in real operating conditions.
