The Centre Tecnològic de Telecomunicacions
de Catalunya is at the forefront of intelligent
all-optical network research and has recently
chosen Polatis DirectLight for use in its
ADRENALINE Test Bed.
The ADRENALINE acronym is derived from a
description of the system i.e. an
All-optical
Dynamic REliable
Network
hAndLINg
IP/Ethernet Gigabit traffic with
QoS (Figure 1). This test bed is an intelligent
all optical network consisting of (up to) 14
Optical Connection Controller (OCC) nodes,
enabling experiments for disparate topologies. It
employs DWDM technology for large transport
capacity, along with a distributed Generalized
Multi-Protocol Label Switching (GMPLS) based
control plane to provide both dynamic and
real-time provisioning of end-to-end optical
connections between clients and services. A
distributed management plane, which combines the
standard Simple Network Management Protocol (SNMP)
with the user-friendly eXtensible Markup
Language(XML), is also deployed.
Figure 1: Architecture of the
ADRENALINE test bed.
The enormous flexibility of ADRENALINE
makes it suitable for many applications, some of
which include field trials for metropolitan
optical networks, design and evaluation of latest
state-of-the-art techniques in optical networking
and evaluation of the performance of different
types of traffic.
The addition of a Polatis 32x32 optical
switch tray is part of a project to add a 4th node
to the system. ‘This additional node will greatly
enhance our capabilities and enables full mesh
network applications’ stated Iván Martínez, CTTC’s
research engineer with responsibility for running
ADRENALINE. Martínez added ‘The automatic
protection and dark fiber switching feature
incorporated into the Polatis unit will also
enable rapid network reconfiguration in response
to simulated line failures.’
Utilizing patented DirectLight™ technology,
Polatis switches are ideally suited for use in
Mesh networking as well as other advanced
architectures. The optional power monitoring
and physical layer protection switching
capabilities of the matrix allow optimal
utilization of the automated control layer, while
the dark fiber switching capabilities of the
switch provide immediate, full-time availability
of alternate network configurations for rapid,
automated traffic rerouting and restoration.
Featuring world-class optical performance and full
transparency, the Polatis switch accommodates
virtually any transmission protocol or line rate,
enabling enhanced capabilities to intelligent
automated networks.
The CTTC team can offer support to
organizations that, for example, are deploying
dark fiber and need to conduct field trials with
the latest technology or simply aiming to apply
advanced networking techniques and would like to
test them in a real scenario, e-mail: raul.munoz@cttc.es
