Techopedia Explains Core Router

By the 1980s, Cisco was the largest core router vendor. In early 2001, Internet services quickly expanded, but providers were unable to offer new solutions because of the high cost of network infrastructure and devices. Core routers were purchased at high costs by some companies; other companies simply left the information technology (IT) market. Eventually, Cisco offered core routers in bulk at reduced costs.
