Nokia Siemens Networks wins major carrier ethernet contract in China

Nokia Siemens Networks has signed a contract with Yunnan CTC, a branch of China Telecom in the country’s south-west province, for the supply and implementation of carrier ethernet switches.

Yunnan Telecommunications Co., Ltd. has over 5 mln fixed line telephone users and 1 mln data Internet users.

The SURPASS hiD 6650 carrier grade ethernet switches will enable Yunnan CTC to enhance and optimize its existing network in terms of traffic engineering, quality of service, administration, resilience, security and scalability. This will let the carrier offer a multitude of residential and business services – ranging from telephony to video on demand and virtual private networks (VPNs) – over one network.

The deployment 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.

Zhang Zhiqiang, Head of Nokia Siemens Networks Greater China Region, said 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 to improve its traffic engineering to ensure that bandwidth is utilized in an ideal way.
