20 Outline of this presentation Specific technology/innovation developed at UPC and currently commercialized by Talaia Networks Main features Value proposition towards end-customers Market/business opportunity Specific technology/tool that UPC contributed to develop in DICONET project Main features Value proposition towards end-customers Joining both technologies 09/05/2014 Value proposition Potential end-customers Market/business opportunity International Open Workshop on Optical Communications Systems and Networks 25

21 NPOT: Network Planning and Operation Tool Main features NPOT integrates in a common platform cross-layer algorithms (it was the key innovation of DICONET) In operation mode, NPOT provides online IA-RWA and the Failure Localization modules. NPOT can be also used in off-line mode for planning The NPOT core is the QoT estimator*. The various components of the tool consult the QoT estimator to make physical layer aware decisions For the RWA process, whether online or offline, NPOT uses the QoT estimator either as a quality metric during the routing and wavelength assignment process or after the routing and wavelength assignment has taken place, to evaluate and validate the computed solution * QoT estimator utilizes updated global network information stored in two external databases, namely the Physical Parameters Database (PPD) and the Traffic Engineering Database (TED) 09/05/2014 International Open Workshop on Optical Communications, Systems and Networks 26

22 NPOT: Network Planning and Operation Tool Value proposition towards the network operators NPOT NPOT provides dynamic and impairment-aware networking operation that maximizes the utilization of the existing WDM infrastructure NPOT is applicable to both the planning and operational phases of a core optical network (either transparent or translucent) with features not limited to the control and management planes, but also take advantage of the optical layer in an integrated cross-layer manner NPOT provides resource optimization, dynamicity and resilience provisioning, which outline a network that offers cost effectiveness NPOT effectively utilizes today s (WDM networks) technologies to optimize the network, and paves the way for a smooth migration to the next generation core networks driven by technological evolution... 09/05/2014 International Open Workshop on Optical Communications, Systems and Networks 27

25 Joining both technologies Value proposition In this evolutionary context, we propose to increase the knowledge of the network behavior, introducing the Multilayer Traffic/Signal Monitoring concept Based on integrating of both Talaia-TM and NPOT in a single device To be designed as an appliance embedded in the network routers and switches The exploitation of this concept can lead to an efficient planning, operation and troubleshooting of the network 09/05/2014 International Open Workshop on Optical Communications, Systems and Networks 30

26 Integrating both Talaia TM and NPOT In the operation mode, potential topics to be addressed are: Automatic triggering of connection demands (setup/teardown demands) based on the traffic prediction Fast Connections/Optical Path rerouting, and Bandwidth reallocation, including enhanced traffic grooming mechanisms Increase the degree of dynamicity with higher bit rates, mixed transmission characteristics, and flexigrid network components Network resources optimization: Traffic Engineering Accurate QoS provisioning: Application discrimination, SLA accomplishment Reduction of the energy consumption: Adaptation to the fully powered systems to the load 09/05/2014 International Open Workshop on Optical Communications, Systems and Networks 31
