Optimize Data Transfer Efficiency with WAN Optimization Controllers
WAN Optimization Controllers are appliances that optimize data-transfer efficiencies across a wide area network (WAN). It is a collection of techniques that optimize bandwidth to improve the end user’s experience. WAN optimization controllers use a combination of techniques such as compression, latency optimization, forward error correction, caching / proxy, deduplication, traffic shaping, application acceleration, network acceleration equalizing, protocol spoofing, connection limits, simple rate limits to accelerate applications and reduce the cost of delivering applications over wide area networks.
Normally enterprise users experience great performance when using applications and services over a LAN. However, they face problems when accessing remotely the same applications and services over the WAN. Accessing applications across a WAN introduces network congestion, latency, and packet loss that can dramatically slow remote end user response time. Many IT organizations increase their spending by adding more network bandwidth to address these issues, only to find that poor application response time over the WAN has not changed. Moreover, with the addition of Virtualization, many enterprises are consolidating servers into corporate data centers. However, the consolidation of applications out of the branches and into the data center puts even more strain on the corporate WAN. In some cases, this degrades end user response time even further. That is where WAN or network optimization appliances come useful. The following are some of the benefits of using the best of breed WAN optimization controllers.
* Reduces remote application response times by up to 95%
* Reduces network bandwidth utilization by up to 95%
* Purpose-built to reduce the impact of network congestion, latency and packet loss which combine to dramatically slow end-user response times
* Application-specific WAN optimization blueprints and specific protocol optimization eliminates redundant, chatty protocol traffic
* Stream-based differencing avoids transmission of content already in the local data store, while compression techniques reduce the amount of data on the wire
* Window resizing, persistent connections and small packet aggregation dramatically improve overall TCP performance
* Supports 50% more accelerated connections as compared to alternative appliances
* Virtual appliances use minimal system resources, can reside with other applications and scale linearly with the addition of CPU cores, memory and disks
* Enables easier management of virtual and physical deployment, transparent addressing, statistical performance dashboard and auto discovery
* Provides centralized provisioning and management through integration with Virtualization management systems
Thus by deploying WAN optimization controllers, enterprises can ensure a premium application experience for all users and achieve rapid ROI by lowering overall bandwidth costs.
