Telefónica and Huawei have successfully completed laboratory tests on Huawei's T-SDN (Transport Software-Defined Network) solution and have now moved onto the network development stage.
The solution is a controller which
improves the planning, management, monitoring and diagnosis of
Telefónica España’s photonic mesh.
The controller enables all communication on the photonic mesh,
to be sent using optics transporting large volumes of data by
Commenting on the announcement, María Antonia Crespo,
director of IP connectivity and transport at Telefónica
España, said: "We were interested in seeing how T-SDN
technology can help Telefónica in many different areas.
Firstly, we’d like to improve the performance of
the WDM control plane, helping to reduce restoration times. We
also hope that it will enable Telefónica to manage its
resources more efficiently and improve its network diagnoses.
Finally, it will be very useful for us if we can move towards
the automation of the network, as this is one of the key goals
in Telefónica’s strategy for the coming
Telefónica began deploying its photonic mesh network
in 2009, covering more than 200 locations in Spain, using
flexible ROADM (Reconfigurable Optical Add/Drop Multiplexer)
technology and an advanced network control plane. With this
improved flexibility and came challenges with the Operation and
Maintenance (O&M) which led Telefónica to test
Huawei T-SDN solution. Huawei’s centralised
controller can be used as the 'network’s
brain’ to gather real-time information and to use
online incident simulations to compile reliable information on
In addition, the centralised T-SDN algorithm can be used to
optimize the spectrum and improve the reliability and
performance of the new WDM (Wavelength Division Multiplexing)
networks. Huawei has also said that it is developing a new
platform called NCE (Network Cloud Engine) which wil integrate
the online WDM planning tool, the control plane and the network
"Huawei continues to lead the global deployment and use
cases of T-SDN. This solution has been implemented in more than
ten networks for customers in different countries and has
supported diverse business scenarios, including finance,
governments, leased company lines, the media industry and data
center interconnect (DCI). This solution has been highly
praised by customers. Huawei will continue its close
cooperation with Telefónica to reinforce its transport
network and to provide the best service experience in Spain,"
added Richard Jin, president of transmission at Huawei.
Earlier this month, Philippines operator PLDT selected Huawei
to help improve its wireless service delivery across all its
brands. PLDT said that the move is part of its "massive
capital expenditure programme" and will see Huawei help
overhaul PLDT’s fixed and wireless networks
infrastructure and its information technology systems.
