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.
