What Is AVVID?
AVVID is the Cisco Architecture for Voice, Video, and Integrated Data. AVVID is an open architecture that is used by Cisco partners to develop various solutions. Every Cisco partner solution is rigorously tested for interoperability with Cisco products. AVVID is designed for large enterprise networks requiring an infrastructure that can support emerging applications such as IP telephone, content delivery, and storage. This network of networks concept allows the use of a single network infrastructure to support the concurrent operation of multiple solutions. The Cisco Enterprise Solutions Engineering team creates design guides for use when planning enterprise network infrastructure using Cisco products, software, and features.

These solutions provide the following benefits:
Network performance
Measured by the following three metrics rather than just throughput:
— Application response time This metric measures how well an application responds to changes on a network and how well it responds to network congestion and changes its link speed.
— Device performance This metric measures the limitations in performance of individual network devices such as switches or routers. A poorly performing device can become a bottleneck to the network, so it is important that devices are not overtaxed. Device performance measures errors, drops, and CPU usage as well as packet-per-second throughput.
— Protocol performance This metric measures the ability of devices to operate dynamically by verifying that devices and the network can handle the use of routing protocols and the Spanning-Tree Protocol (STP).
