Huawei and Shaanxi Telecom, a subsidiary of China Telecom, announced the successful commercial deployment of the world’s first five terabits per second (Tb/s) cluster router system on the operator’s metropolitan area network in Xi’an.

Huawei’s NE5000E multi-chassis cluster systems with 2.56Tb/s capacity have been serving Shaanxi Telecom since 2006, where their reliability and performance were put to the test by the largely-populated network. With the traffic of 3G services and multi-media applications continuing to grow rapidly, Shaanxi Telecom has successfully upgraded the capacity of its existing Huawei cluster router of 2.56Tb/s to 5Tb/s (4 cluster line-card chassis each with 1.28Tb/s capacity and 2 cluster central chassis configuration) without service interruption and hardware replacements.

Huawei, a long-term strategic partner of Shaanxi Telecom, has been leveraging its experience in IP technologies to provide the operator with stable and reliable field services. The successful deployment of the 5Tb/s cluster router system will enable Shaanxi Telecom to address customer demand for high bandwidths, and will also provide a solid foundation for future network evolution.

“We are honored to work with Shaanxi Telecom to deploy the world’s first commercial 5Tb/s cluster router system,” said Zha Jun, Vice President of Network, Huawei. “This again demonstrates our leadership in IP technology, following our launch of the industry’s first 10Tb/s cluster router solution in 2008. We will continue to help operators worldwide to build flexible, scalable, and sustainable networks through our customized solutions.”
