Appendix 4 - NetEqualizer Caching Option (NCO)

We have developed an embedded caching capability used to cache frequently used, static
content, primarily YouTube videos. The NetEqualizer Caching Option (NCO) runs directly on
the NetEqualizer 3000 and 4000 series. When NCO is activated, a squid proxy server and

web cache daemon are loaded, along with proprietary NetEqualizer Caching configuration
and integration software and a new internal solid-state drive (SSD).

The NetEqualizer Caching Option is integrated with Equalizing, providing a comprehensive
bandwidth management strategy. Traffic can be accessed from cache or accessed from the
Internet and equalized, as needed.

NCO caches all port 80 traffic file sizes from 2MB to

40MB, including YouTube videos

. Any type of static content that is frequently accessed will

benefit from caching.

To get a good overview of this feature, read our

Caching Executive Whitepaper

. To deepen

your knowledge and better understand the technical details, please read our

Caching

Technical Whitepaper

.

There is a one-time initial activation and set-up charge for the NetEqualizer Caching Option.

The caching software itself is covered under NSS; to get future releases, you will need to be
current on your

NSS

.

Caching Set-up

The NetEqualizer Caching Option (NCO) set-up is customized to work in each customer's
environment. Therefore, we do not include set-up steps here. Rather, to work with our
Support Team to get NCO installed in your environment, contact

[email protected]

or call 303.997.1300 x102.
