Chapter 1 Introducing the Cisco Wide Area Application Engine
Software Functional Description
ACNS Software Description
With ACNS software installed, the WAE appliance functions as a Content
Distribution Manager, Content Engine, or Content Router. The Content
Distribution Manager provides a graphical user interface to manage registered
Content Engines and Content Routers. The ACNS solution addresses the need to
distribute and receive high-bandwidth, media-rich content across the Internet or
an intranet without performance losses or content-delivery delays.
ACNS software offers the following content-based services:
• Content caching and hosting
• Proxy services
• Content replication
• Video streaming
In Content Engine mode, the WAE operates either as a component of an ACNS
network or as a standalone content-caching device and is generally positioned on
the WAN edge between your enterprise network and the Internet.
Note The WAE-611 supports device-mode configuration and can be configured with
ACNS 5.x software to operate as a Content Engine, a Content Router, a Content
Distribution Manager, or an IP/TV Program Manager. The WAE-511 operates as
a Content Engine only.
To deploy Cisco Content Engines with Cisco ACNS software within your existing
network, your network must support Cisco IOS software and the Web Cache
Communication Protocol (WCCP). WCCP transparently redirects HTTP requests
to a Content Engine, and the Content Engine responds to those requests.
WAFS Software Description
With WAFS software installed, the WAE appliance functions as a File Engine.
The File Engine is an Internet file delivery device that provides the following
file-based services:
• Segment-level file and metadata caching
• Protocol-specific latency reduction
