D4.2 - Testbed description and implementation update

Executive Summary:

This deliverable presents the work performed by STRAUSS project during its second year (Y2) in terms of implementation, integration and demonstration activities. STRAUSS project has focused on having realistic results, which are validated with prototypes not only for data plane, but also for and control plane solutions defined in the project. This document provides a both a description of the testbeds which are considered in the STRAUSS project and it also provides and update of the plans and preliminary results of the experimental activities done in the project during Y2.
The experiments described in this document provide a set of tests to tackle the different activities which are carried out jointly by European and Japanese partners in WP4. There have been four main join activities:

  • OPS/OCS integrated network testbed. The OPS/OCS integrated network testbed will be located in Japan and Europe and it will provide an integrated solution from an overall system perspective. The testbed in Japan will focus on OPS, while the EU partners will focus on Elastic Optical Network (EON) to adopt the flexi-grid. With the advance of OPS and OCS technologies, an end-to-end Ethernet service provisioning and orchestration across multiple domains with heterogeneous transport and control plane technologies will be demonstrated for variable application scenarios.
  • SDN network architecture orchestration. The SDN architecture will use a hierarchical approach based on the ABNO architecture, which has been proposed as a multi-technology and multi-domain network orchestration solution. The ABNO controller is the main component of the architecture and is responsible for controlling the workflows for both OF-controlled OPS and EON domains, which are run by KDDI and University of Bristol, respectively, an OF domain from ADVA in Telefonica premises and the GMPLS EON domain in CTTC.
  • Transport virtualization visor. The proposed Virtualization Visor (VV) system architecture provides a mechanism for virtualizing transport nodes and links. The partitioning of the resources is performed by the VC, and to this end, the proposed system architecture incorporates a generic network abstraction mechanism for the different transport infrastructure resources (e.g., OPS, EON). Three virtualization domains are expected: (1) KDDI with an OF-controlled OPS domain, (2) CTTC with a GMPLS-controlled EON domain and (3) UNIVBRIS with an OF-controlled EON domain.
  • SDN-enabled S-BVT based on multicarrier technology. This activity focuses on the integration of a sliceable transceiver (S-BVT) composed of multiple sub-transceivers based on multicarrier modulation technologies within the ADRENALINE testbed by CTTC, HHI, University of Bristol, Fujitsu and Osaka University. The main idea is to demonstrate an SDN-enabled generation of multiple flows to be routed and switched on the ADRENALINE network. The programmable S-BVTx and S-BVRx are SDN controlled by means of SDN agents enabling rate/distance adaptive transmission and advanced functionalities for optimal spectral usage. Furthermore, unique granularity, flexibility and grid adaptation is provided by using two multicarrier technologies, which are the DMT and the OFDM. The multiple slices are generated by the adaptive transceivers provided by EU-Japan STRAUSS Partners. According to the required/supported rate/distance adaptive transmission, data flows are selectively filtered and switched to be suitably routed over the network, which is controlled by an Active Stateful PCE.
