Reaping The Benefits Of WAN Optimization Controllers

Though ensuring acceptable and standard application delivery has always been a crucial aspect, historically it was never a top priority for IT enterprises. It underwent a change many years back when the IT organizations started to focus in a dedicated manner on application delivery on a huge part of responding to the performance challenges related to supporting applications that were in turn delay sensitive and supporting huge file transfers between branch offices and headquarters. A major medium through which IT enterprises were responding to these performance challenges was by implementing WAN optimization controllers.

 

In most cases, WAN optimization controllers were deployed as a “stand-alone” hardware-based device. Owing to the mass adoption of Virtualization, IT enterprises today are witnessing a new kind of application delivery challenges. For instance, successful desktop Virtualization is a crucial factor that will compel IT enterprises to support a significant increase in delay sensitive WAN traffic. In order to aid this situation service providers specializing in RDP remote access have introduced WAN optimization controllers with multiple features, that helps in:

 

* Minimizing the remote application response times by up to 95%

* Minimizing the network bandwidth utilization by up to 95%

* Is purpose-built to bring down the impact of network congestion, latency and packet loss that combines to significantly slow end-user response times

* The Application-specific WAN optimization blueprints and specific protocol optimization helps in reducing redundant, chatty protocol traffic

* Stream-based differencing averts transmission of content already in the local data store and the compression techniques minimizes the amount of data on the wire

* Is available in hardware and virtual appliance form factors, that helps to achieve ROI within a less time frame

* Supports 50% more speeded up connections

* The virtual appliances make use of minimal system resource, can stay with other applications and scale linearly with the addition of CPU cores, memory and disks

* Helps in easier management of virtual and physical deployment, transparent addressing, statistical performance dashboard and auto discovery

* Offers centralized provisioning and management by incorporating with Virtualization management systems

 

Furthermore, advanced WAN optimization controllers make use of a combination of application acceleration, packet compression, network acceleration, protocol optimization and caching to speed up the applications and minimize the expense of delivering applications across wide area networks.

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.
