According to the agreement, Nokia Siemens Networks will carry out a large-scale Carrier Ethernet switch deployment in China's south-western province of Yunnan. The deployment has started at the end of July and the network is planned to start operations in September.

"With the fast adoption and development of Internet applications in Yunnan we need to optimize the network with advanced ERP technology and bring rich broadband services such as IPTV and VOD to end users," said Li Hua, Chairman and General Manager of Yunnan CTC. "Nokia Siemens Networks' Ethernet solution, which has been widely adopted globally, will help us to fulfill this demand."

Zhang Zhiqiang, Head of Nokia Siemens Networks Greater China Region, said: "We are very proud to be selected by Yunnan CTC as its major C arrier Ethernet solution supplier. With the deployment of Nokia Siemens Networks' innovative Carrier Ethernet solution in the province of Yunnan, we will be able to help the operator build high capacity and reliable networks. Plus, the switches will pave the way for an evolution towards broadband-based multi-service IP networks and IP convergence."

The new Carrier Ethernet switches will significantly increase the operational readiness of the network. The platform features Ethernet Ring Protection (ERP), which ensures a recovery time of less than 50 milliseconds. Comprehensive mechanisms ensure Quality of Service and allow demanding applications like IPTV. To ease administration, the switches support a comprehensive VLAN scheme, including Service-VLAN. This technology aggregates applications in order to group users with identical service demands, instead of doing it on a more inefficient per user basis. The support of IEEE 802.1ad Ethernet packets, also known as QinQ, will allow the carrier improve its traffic engineering to ensure that bandwidth is utilized in an ideal way.
