WLANs are part of Cisco’s Architecture for Voice, Video, and Integrated Data
(AVVID). An overview of AVVID is shown in Figure
. As the primary
enterprise-wide, standards-based integrated network architecture in the
industry, AVVID provides the roadmap for combining business and technology
strategies into one cohesive model.
The intelligent network
infrastructure of AVVID includes a variety of clients, network platforms, and
network services, as Figure
shows.
Another important component is service control, which enables the technologies
to help provide the solutions. Figure
lists Cisco
optimized service controls.
Combining the network infrastructure and services with current and emerging
applications, AVVID accelerates the integration of technology strategy with
business vision. Cisco AVVID is the enabler of Internet business solutions for
customers through the network infrastructure and key partnerships with
developers and integrators.
A network architecture is a roadmap and
guide for ongoing network planning, design, and implementation. It provides a
coherent framework that unifies disparate solutions onto a single foundation.
Cisco AVVID provides the following:
-
Speed – Speed in deployment of applications is facilitated by
totally integrated and tested products. Speed, in terms of bandwidth, is
available in scalable increments, from modest to Gigabit transmission rates.
-
Reliability – Network uptime is increase by fully integrated and
tested hardware and software, as well as by fault-tolerant features.
-
Interoperability – Standards-based APIs allow open-integration with
third party developers, providing customers with choice and flexibility.
Interoperatbility testing guarantees that multiple solutions work together.
-
Pace of change – Customers have the ability to adapt quickly, in a
competitive and changing business environment. This is because new technologies
are continually being integrated into the end-to-end AVVID solution.
-
Cost reduction – Resource and time requirements are minimized, which
helps reduce implementation costs.
-
Mobility – Rewiring and reconfiguration are minimized. Users are
always connected and can roam freely, thereby increasing their productivity
levels.
Once a network architecture has been developed, an organization will
have a framework in place. The framework will allow for more informed decision
making, including especially appropriate investments in network technologies,
products, and services. A sample AVVID topology, including WLAN access, is
shown in Figure
