• Path Computation Element (PCE) server

The ADRENALINE PCE Server is a network appliance that implements a Path Computation Element. It combines, in a single system, a Path Computation Engine and a standard PCEP protocol interface to access Path Computation Services. The system is composed of a main PCE multi-threaded asynchronous process, running as a PCEP/TCP server in order to accept and process path computation requests from Path Computation Clients (PCC). When required, the PCE will also act as a Path Computation Element communication Protocol (PCEP) /TCP client to request path computations to other PCEs in other domains. The application runs on top of a Debian™ GNU/Linux operating system. It supports most current IETF PCE WG standards and has succesfully been deployed in single and multi-domain scenarios.

• Applications for testbed operation

ADNETCONF (ADRENALINE Network Configurator) and ADNETGEN (ADRENALINE Network Generator) are advanced and adapted software applications and tools to allow the rapid operation and maintenance of the testbed, including common tasks such as the configuration and parameterization of the network topology, the generation of client requests modelling the behaviour of network customers, or the monitoring, data-mining and statistical processing of obtained results allowing researchers to obtain numerical performance data and to perform experimental research and quantitative comparative analysis

• Reconfigurable Optical Add Drop Multiplexers (ROADM)

The ROADMs of the ADRENALINE testbed are performed by a two-stage unit. The add/drop stage (first stage) filters the drop channels out of the DWDM signal and adds new channels into the ring. The distribution stage (second stage) assigns the added and dropped signals to the tributary interface cards of the client equipment. The add/drop stage has been designed and developed by the CTTC, and is based on a two array of nine 2x2 reconfigurable optical switches in combination with a single 18x18 Arrayed Waveguide Grating (AWG). This equipment also incorporates a controller card reachable via Ethernet to allow the configuration of the two 2x2 arrays.

• All-Optical Wavelength Converter

The All-Optical Wavelength Converter (AOWC) is a 1U, 19” rack-mount equipment designed and developed at CTTC laboratories, which is controlled electrically but works in the optical domain with two possible operation modes: on one hand it can perform a 2R regeneration (Re-amplification and Re-shaping) on the optical input signal and, on the other hand, it can perform the same 2R regeneration with a wavelength (DWDM channel) conversion of the optical input signal, all in a transparent manner, that is to say without conversions between the optical domain and the electric one.

Key Features:

- 2R optical signal regeneration (Re-amplification & Re-shaping).

- CD and PMD mitigation.

- All-optical wavelength conversion across the entire C-band, with 50GHz channel spacing.

- Bit-rate, bit-shape and protocol transparency up to 12.5Gb/s.

- Ethernet interface for global control and management by a remote process.

- RS-232 serial DB9 interface for monitoring and configuration of the internal regenerator module by an external PC.

- 1U, standard 19" rack-mount equipment.

- Directly pluggable to standard 220V/50Hz line voltage with switch and fused protection.

- Flexibility for overriding the internal optical bandpass filter and for the connection with an external one.

- Flexibility to re-program the internal Universal Network Controller module for the integration within different DWDM Optical Networks.
