ARCH v Summary Cisco AVVID is an enterprise-wide, standards-based network architecture that provides a roadmap for combining business and technology strategies into a cohesive model. While specific devices or applications may promise performance, effective performance is achieved only by considering and optimizing each component. Only a cohesive, integrated, and optimized network can ensure the best network performance. A network must be able to scale from where it is today to where it might be in the future. The design, IP address management, features, and WAN link speeds must all be able to provide connectivity and additions without massive redesign of the network.

The Cisco AVVID network infrastructure component includes clients and servers, network platforms, and intelligent network services. Cisco AVVID network infrastructure supports the key intelligent network services, which comprise numerous networking technologies and topologies, with a corresponding large number of possible designs and architectures. The Cisco AVVID framework provides a foundation for applications and solutions. Cisco provides some solutions, while third-party companies provide solutions through the Cisco AVVID Partner Program.
