MADRID -- Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the successful completion of a joint test on Software-defined Networking (SDN)-based IP and Optical synergy with Telefonica, one of the world’s leading integrated operator in the telecommunication sector operating in 24 countries.

Based on commercially available Huawei Routers and Optical Transport Network (OTN) and Reconfigurable Optical Add-drop Multiplexer (ROADM) optical transport platforms, Telefonica and Huawei jointly completed a series of tests on SDN based IP and Optical synergy, including multi-layer restoration, multi-domain Label Switched Path (LSP) creation, online network survivability analysis, and so on. The new elastic SDN-based IP and Optical network architecture uses centralized controller, Generalized Multiprotocol Label Switching (GMPLS) User-Network Interface (UNI), IP/MPLS, PCEP (Path Computation Element Protocol) and other key technologies to realize centralized control of the multi-layer multi-domain network, achieving E2E fast service provisioning, multi-layer restoration for improved service availability and CAPEX savings, and online network surveillance for preventive maintenance.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
