Enterprise Networks Today: The enterprise of today and tomorrow has requirements that span all four
internetworking sectors: workgroup, IBM internetworking, core, and remote access.
The IOS: Cisco's Advantage
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.
IOS Interfaces: Cisco's IOS supports the industry's largest set of formal and de facto standard
interfaces.
