Cisco Faces a Dangerous New Rival: AT&T
@Cisco (NASDAQ: CSCO), the largest manufacturer of network switches in the world, usually considers @Huawei, @Hewlett-Packard Enterprise, @Arista Networks, and @Juniper Networks to be its main competitors. Cisco controlled over half of the global ethernet switching market last year, according to IDC. However, a recent report from The Information indicates that @AT&T (NYSE: T), one of Cisco’s major customers, is developing its own network switches. That move would reduce AT&T’s costs and give it more flexibility and customization options across its networks. But it also could hurt Cisco by shattering a main pillar of its business model.
