China Unicom has replaced devices of Cisco Systems, Inc. in one of the country’s most important backbone networks, citing security reasons, the 21st Century Business Herald reported.
The replacement project targets “China169” backbone network’s Cisco router in Wuxi, Jiangsu. Analysts indicated that the product vulnerability and back door problems are the main worries of China Unicom.
The move came after a congressional report branded Huawei Technologies Co. Ltd and ZTE Corp security threats in the United States. China domestic operators began to intensify network security since then, the report said.
As the world’s largest maker of networking equipment, Cisco takes high market share in China. It accounts over 70 percent share of China telecom’s 163 backbone network and over 80 percent share of China Unicom’s 169 backbone network.
163 and 169 backbone networks are the most important backbone networks of China, delivering over 80 percent data of the country’s Internet.
Cisco has ended a longstanding sales partnership with ZTE Corp. early this month.
