Scenario: Prefilling content of corporate NetCache appliances

About this scenario

The managers of XYZ Corporation want to provide training videos to their employees in offices across the United States. They want employees to be able to view these videos at any time (video on-demand).

Organization's requirements

The organization's requirements are as follows:

Reduce the amount of traffic on the corporate LAN and WAN
Provide good quality video quickly
Serve training material specific to a particular site from the NetCache appliance at that site
Different corporate sites have different training needs and, therefore, require different video tapes.
Provide all employees in the United States the same corporate information, for example, videos to keep employees informed about the corporation and videos about employee benefits

Deployment illustrated

The following illustration shows content pushed out to different sites of XYZ Corporation.

As the previous illustration shows, the content manager used Network Appliance ContentDirector to push the site-specific streaming media to the three company sites. Additionally, the content manager pushed the same video about corporate news to each site. The content manager pushes the content to the caches as batch jobs at times when the WAN is not busy, for example, at 2:00 a.m.

The requirement to reduce bandwidth use is achieved because employee requests for videos appropriate for their sites can be satisfied from the local NetCache appliance instead of from a remote appliance.

Data can reach the employees more quickly because it is close to the users. Additionally, as the distance the streaming media data needs to travel lessens, the possibilities of network problems that would affect the streaming media are likely to be fewer.

This scenario showed three U.S. sites of a company. If the sites were in different countries, you could push language-specific videos to each site.
