Cisco IOS Software Release 12.0 has added over 38 new enterprise and service-provider features compared to the last major release. It has been designed to enhance the capabilities of enterprise customers in five major application areas: customer care, workforce optimization, supply-chain management, e-learning, and Web foundation (workflow, publishing, data access, and community). Security, settlement services, and billing applications are just a sample of the many service-provider-oriented features introduced in Cisco IOS Software Release 12.0.
By providing a variety of security, switching, QoS, and routing features, Release 12.0 addresses the needs of both the service provider and the enterprise customer. Because the Cisco IOS Firewall Feature Set detects and protects against denial-of-service intrusions, enterprises can guarantee their e-commerce customers a reliable, secure environment. Cisco IOS Software Release 12.0 also provides a vast array of QoS capabilities such as committed access rate, Border Gateway Protocol 4 (BGP4) precedence propagation, and IP Precedence marking, enabling Internet service providers (ISPs) to provide inter-ISP service-level agreements (SLAs) and enterprise virtual private networks (VPNs) with differentiated services.
