Overview of Accelerator
Technology
Network accelerators provide a
combination of functions to help improve the performance of applications over a
network. These functions help to mitigate many of the performance-limiting
factors in enterprise networks today such as those discussed in previous
chapters: bandwidth disparity, congestion, packet loss, and latency, among other
things.
For many applications, the
level of acceleration provided when accessing applications and data over a WAN
where accelerators are deployed is similar to that found when accessing the same
applications and data over a LAN. Thus,
accelerators not only help to improve the performance of user access to data and
applications that are already centralized and accessed over a WAN but also
provide performance levels necessary to enable the centralization of resources
that are commonly deployed in a distributed fashion.
With accelerator
technology, IT organizations are able to more confidently deploy centralized
applications and infrastructure while also enabling the consolidation of a
broader array of services into fewer locations to better meet data protection,
compliance, cost, and management requirements without compromising the levels of
performance that users require to be productive. Accelerators accomplish this
monumental task by employing functionality in two key areas, WAN optimization
and application acceleration, each of which will be explained in great detail in
the upcoming chapters.
