Shanghai Telecom has replaced numerous routers powering its “super” point of presence “POP,” or high-speed core IP network, with the Cisco CRS-1. Shanghai Telecom is the first telecom operator in China to adopt the Cisco CRS-1 Multichassis System, which can be scaled up to 72 line-card shelves, totaling 1,152 slots, providing room for system expansion to satisfy the company’s needs for the next 10 to 15 years.

As China’s largest Internet service network, ChinaNet currently offers services countrywide with more than 18 million broadband subscribers and a total capacity of 4,000 Gbps, accounting for more than half of China’s bandwidth for Internet services. Cisco CRS-1 transited the previous multi-router structure of ChinaNet’s core network nodes in eight cities: Beijing, Shanghai, Guangzhou, Tianjin, Xi’an, Chengdu, Wuhan and Nanjing. After integration, ChinaNet significantly enhanced the network capacity and improved management efficiency, enabling China Telecom to strengthen broadband business as well as laying foundation for the development of next-generation Internet applications.
