Huawei and Telefonica have successfully completed a joint field trial for a Software-defined Networking (SDN)-based IP and Optical Synergy with Telefonica Peru subsidiary - a key milestone to commercializing the SDN-based IP and Optical Synergy solution.
The field trial network was set up using mesh topology, leveraging Huawei OSN8800 as ROADM, OSN9800 as packer-aware OTN switches, NE40E as service routers and NE5000E as core routers to form a fully Internet Protocol/Multiprotocol Label Switching/Optical Transport Network/ Reconfigurable Optical Add Drop Multiplexer (IP/MPLS/OTN/ROADM) multilayer network. The controller and orchestrator are based on Huawei’s commercially available Smart Network Controller (SNC) and NetMatrix.
According to Huawei, the field trial concluded all test cases related to the network automatic provisioning, multi-layer service provisioning, multi-layer network restoration, path diversity and shared risk link group avoidance. The company added that it will continue to engage Telefonica in promoting SDN-based IP and Optical Synergy solution standardization and commercial deployments.
