China Unicom has successfully deployed a Transport-software-defined networking (T-SDN) project on the Hangzhou metro transport network to provide bandwidth on demand (BoD) leased lines for government and enterprises. The deployment in partnership with Huawei is part of the operator's Cloud-oriented Ubiquitous-Broadband Elastic Network (CUBE-Net 2.0) strategy.

The T-SDN BoD enables group customers to handle leased-line services online using a self-service terminal, such as a tablet, and monitor leased-line performance anytime and anywhere, including SLA and delay. In this way, Huawei said the T-SDN achieves on-demand bandwidth subscription and rapid service deployment, greatly improving customer experience. In terms of hardware, Huawei provided its MS-OTN bearer solution that implements unified cross-connect and grooming for multiple services to construct metro transport networks.

Hu Hui, general manager of the subsidiary's network construction department
Huawei’s T-SDN BoD solution meets China Unicom's strategic requirements for future transport networks and satisfies the actual requirements of group customer leased line services at the Zhejiang subsidiary. We will continue to work with Huawei in the T-SDN field to proactively promote the commercial use of T-SDN.

Zha Jun, president of Huawei’s Fixed Network BU
Huawei uses T-SDN to simplify network architecture and build flattened and automated agile networks and continuously provides the optimal T-SDN solution for carriers, helping carrier network transformation.
