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.
