Cisco IOS is the key differentiator that separates Cisco's internetworking solutions from other alternatives in the industry. Its value-added intelligence supports users and applications throughout the entire enterprise and provides security and data integrity for the internetwork. The IOS cost-effectively manages resources by controlling and unifying complex, distributed network intelligence. Also, it functions as a flexible vehicle that can add new services, features, and applications to the internetwork.
In the applications support arena, the Cisco IOS provides interoperability with more standards-based physical and logical protocol interfaces than any other internetwork supplier in the industry. From twisted pair to optical fiber, LAN to campus to WAN media, UNIX to Novell NetWare to IBM SNA, no other internetwork architecture can match the wide-ranging protocol support of the IOS.
