PL-LAB provides an access to distributed laboratory, spread around Poland and interconnecting major academia institutions and offering variety of equipment with different functionalities at a large scale. The major focus of experiments performed so far in PL-LAB was on how to enable Parallel Internet paradigms in future networks. The clean-slate approach has been proposed and validated in the testing infrastructure. The equipment available in PL-LAB creates opportunities for such experiments, allowing an implementation of low-level network functions in network processors and net-fpga boards.
PL-LAB is a distributed laboratory for Future Internet built of eight laboratories interconnected over the Polish NREN – PIONIER. The laboratories are geographically dispersed, and associated with leading Polish research and academic centers (Warsaw University of Technology, Poznan Supercomputing and Networking Center, National Institute of Telecommunications, Gdansk University of Technology, Poznan University of Technology, Wrocław University of Technology, The Institute of Theoretical and Applied Informatics and AGH University of Science and Technology).
The hardware available in PL-LAB is categorized and listed in the following table.

The variety of deployed hardware creates opportunities to perform experiments on subjects like Content Aware Networks, IPv6 practical deployment, 4K 3D video streaming, or introducing Parallel Internets concept based on infrastructure virtualization. The combination of network, applications, protocols and unique hardware gives high potential for solving Future Internet problems and allows validation of solutions and architectures which are expected to fulfill current and arising demands for connectivity services at the global level. Distribution of the equipment in the testbed is shown on Figure 1.
The primary objective of PL-LAB is to create point-to-point and multipoint-to-multipoint topologies with dedicated capacity between particular laboratory equipment located in different laboratories. Such connections constituting a PL-LAB User Laboratory, are isolated from both non-PL-LAB traffic, and other simultaneously running PL-LAB experiments. The usage of the Polish NREN high capacity network infrastructure – PIONIER, as the backbone network, guarantees high bandwidth and a scalable environment which can merge eight laboratories into one distributed environment. The independence from Internet infrastructure gives an advanced traffic policy management, flow controls and reliability for inter-laboratory connections.
PL-LAB management system, named PL-LAB Access System, supports researchers performing experiments in PL-LAB network. Its functionalities comprise handling different user requirements and experiment requests, automatic configuration and access to experiments, scheduling mechanism, monitoring facility, maintenance of infrastructure and users virtualized laboratories (experiment environment).
PL-LAB Access System is currently being enhanced in order to fully integrate PL-LAB facility with the Fed4FIRE federation.
FUTURE INTERNET ENGINEERING PROJECT
The PL-LAB facility was built within the Future Internet Engineering (FIE) project with the goal to deliver an infrastructure platform for developing and validating innovative systems designed within the FIE project. The FIE System uses virtualized network infrastructure that allows to set up a number of, so called Parallel Internets, essentially differing in solutions for the data and control planes. The Parallel Internets are: (1) IPv6 QoS that basically explores DiffServ and NGN architectures and uses TCP/IP, (2) Content Aware Network specially designed for efficient content delivery, and (3) Data Streams Switching for handling constant rate traffic with strong QoS requirements. More information on FIE concepts are available on PSNC website: http://www.man.poznan.pl.
