Huawei has announced the successful completion of a joint test on Software defined Networking (SDN) based IP and Optical synergy with Telefonica.
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, and online network survivability analysis.
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.
Mr. Zha Jun, President of Huawei's Fixed Network Business Unit, said: "The evolution from traditional networks to SDN networks will open up network capabilities, support rapid technology innovation, improve network performance, as well as reduce operation and maintenance costs based on virtualization, automation, and intelligentization."
