AVVID Characteristics
Cisco AVVID Network Infrastructure is the network foundation that is essential for rapid and seamless deployment of emerging technologies and new Internet business solutions into the retail environment.

As with any architecture, Cisco AVVID relies upon a strong and stable foundation. This foundation is built upon the multiprotocol routers and multilayer LAN switches that are used as building blocks for enterprise networks.

While best-of-breed solutions may promise high performance for a specific device or application, performance is limited by the network's weakest link. Only a cohesive, integrated, and optimized network can ensure the best network performance. Cisco AVVID Network Infrastructure is not only tailored to the characteristics of the enterprise, but it is also thoroughly lab tested and documented to provide benefits that include:

- Speed – Defined architectural framework and consistent services allow rapid deployment of new applications and enable an enterprise to quickly address change without re-engineering the network
- Reliability – A consistent architectural approach combined with a tested and verified network design increases network dependability.
- Flexibility – Architecture based on Cisco AVVID Network Infrastructure allows easy transition to changing business requirements.
- Interoperability – All equipment and software is configured for the ideal fit that will allow seamless operation. Multiple solutions work together based on a common architectural approach.
- Simplification – Products are strategically deployed in alignment with the architectural framework, resulting in streamlined processes
- Reduced cost – Predefined and proven architecture minimizes the resources and time required to implement network strategies measurements, and Resource Reservation Protocol (RSVP) signaling for admission control and reservation of resources.
- Security – Ensures the security of the network through authentication, encryption, and failover. State-of-the-art security features include stateful, application-based filtering (context-based access control), defense against network attacks, per-user authentication and authorization, and real-time alerts.
- High Availability – Optimizes design and tools to ensure end-to-end availability for services, clients, and session. Tools include reliable, fault-tolerant network devices to automatically identify and overcome failures and resilient network technologies such as Hot Standby Router Protocol (HSRP) to bring resilience to the critical junction between hosts and backbone links, and Simple Server Redundancy Protocol (SSRP) that communicates between router and ATM switch groups to detect device failures and initiate automatic.
