Telefonica and Huawei Team Up for Testing


January 19, 2018

Spain-based Telefónica and China-based Huawai announced the successful completion of lab tests on the T-SDN (Transport Software-Defined Network) solution. The testing goal was to prove the controller could include enhancements for planning, management, monitoring, and diagnosis of Telefónica’s photonic mesh.

“We were interested in seeing how T-SDN technology can help Telefónica in many different areas,” said Director of IP Connectivity and Transport at Telefónica España María Antonia Crespo. It has been working on photonic mesh for almost a decade, across 200 locales in Spain. That was when Huawei joined in to see what the advantages of a T-SDN solution would be.

“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 years,” added Crespo.

The T-SDN solution collects data in real-time, identifying any internal network issues and establishing interferences in advance. This assists photonic mesh as the perfect route is essential to carry significant data amounts. Additional improvements via the T-SDN are spectrum enhancement and increased reliability and performance of the Wavelength Division Multiplexing (WDM) networks.

In 2017, Telefónica worked on T-SDN testing alongside NEC/Netcracker, Infinera, and Juniper in the Optical Internetworking Forum (OIF)/Open Networking Foundation (ONF) Transport API project.

This is also not Huawei’s first time in this market, as President of Transmission at Huawei, Richard Jin note, “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.”

Day 2, Cisco Live!

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.
