Summary


In this chapter, you learned about integrating content networking devices into your network; the following topics were presented:

  • The benefits of employing the CN intelligent network solution.

  • The following components that are used in CN:

    - Content engine Caches, or stores, selected content from origin servers and sends it upon request to users. When not used with a content router, a content engine can be deployed in a network in three ways: transparent caching, nontransparent caching, and reverse proxy caching.

    - Content router Directs users' requests for content to the closest content engine. A content router can operate in either direct mode or WCCP mode.

    - Content distribution and management device Responsible for distributing content to the content engines and for ensuring that the material is kept up to date.

    - Content switch Load-balances requests to servers, content engines, or firewalls.

  • The three types of content: on-demand, live, and pre-positioned.

  • Example CN design scenarios.
