Virtual appliance - Relationship to WAN optimization
Software-based WAN optimization
virtual appliances are an excellent
alternative to single-purpose
hardware appliances, and enable high
performance, agile and cost-effective
WANs which can act as solid
foundations for those enterprises and
managed service providers
considering virtualization and cloud
computing.

WAN optimization

'WAN optimization' is a collection of
techniques for increasing datatransfer efficiencies across wide-area
networks. In 2008, the WAN
optimization market was estimated to
be $1 billion, and it will grow to $4.4
billion by 2014 according to Gartner, a
technology research firm.

WAN optimization

WAN optimization has been the subject
of extensive academic research almost
since the advent of the WAN. In the early
2000s, research in both the private and
public sectors turned to improving the
end-to-end throughput of TCP, and the
target of the first proprietary
software|proprietary WAN optimization
solutions was the Branch WAN. In recent
years, however, the rapid growth of
digital data, and the concomitant needs
to store and protect it, has presented a
need for DC2DC WAN optimization.

WAN optimization
Component techniques of Branch
WAN Optimization include
deduplication, Wide area file
services|WAFS, CIFS proxy, HTTPS
Proxy, media multicasting, web
caching, and bandwidth management.
Requirements for DC2DC WAN
Optimization also center around
deduplication and TCP acceleration,
however these must occur in the
context of multi-gigabit data transfer
rates.

improve bandwidth consumption and
perceived latency between dedicated

enterprises, WAN optimizers are
deployed near both sending and

Application delivery network

In the branch office portion of an ADN

Application delivery network - Data compression and caching
A separate class of devices known as
WAN Optimization Controllers (WOC)
provide this functionality, but the
technology has been slowly added to the
ADN portfolio over the past few years as
this class of device continues to become
more application aware, providing
additional features for specific applications
such as CIFS|CIFS and SMB.
