This section looks at the design concept of the Cisco AVVID. Cisco AVVID is the only enterprise-wide, standards-based network architecture that provides the foundation for today's converged networks. Cisco AVVID provides the roadmap for combining your business and technology strategies into one cohesive model and encompasses the following:
Converged client devices
Hardware and software
Directory services
Call processing
Telephony and data applications
Network management
Service and support
Cisco AVVID provides the baseline infrastructure that enables enterprises to design networks that scale to meet Internet business demands while delivering the e-business infrastructure and intelligent network services that are essential for rapid deployment of emerging technologies and new Internet business.
Cisco AVVID consists of several building blocks, including
Network infrastructure
Service control
Communication services
Cisco AVVID Network Infrastructure provides an enterprise foundation that combines IP connectivity with security, high availability, and QoS. Table 12-4 shows the network infrastructure components defined within Cisco AVVID.
Component | Description |
|---|---|
Clients | Network clients include Cisco IP Phones, wireless devices, PCs, and laptops. These standards-based devices can be interconnected and functionality can be added through intelligent network services. |
Network platforms | The network platforms comprise routers, gateways and switches, servers, firewalls, and other devices. This layer of the architecture provides the basis for a complete networking solution. |
Intelligent network services | The intelligent network services are platforms, network services, appliances, and management that allow business rules and policies to be reflected in network performance. |
The Service Control interface joins the Internet technologies to the Internet business solutions. This software element performs network fine-tuning and optimization, and its functionality is provided through the following:
VPN/security control
Perimeter control
Call control
QoS/policy control
Video media control
Content distribution control
Wireless access control
Directory control
The convergence of media types is enabling richer interactions and greater personalization of applications and services, including
Unified communications
Intelligent contact management
Collaboration
