Wan Acceleration

Discover how NetOut can help you gain bandwidth, reduce costs and consolidate servers by utilizing wan application acceleration devices.

Increase Bandwidth

Enterprise businesses of all kinds struggle to balance the competing demands of cost containment and increased network traffic. Since WAN costs typically account for IT's highest expenditure after headcount, most enterprises do not have the luxury of simply adding more WAN capacity to their networks. What accounts for the rise in bandwidth demands?

Web-enabled applications. These architectures typically increase bandwidth tenfold compared to client-server architectures performing the same transaction.
Broader proliferation of applications. In the past, fewer workers within a business accessed any given application, while today many more employees across many more sites need access to the same application.
Global integration. While businesses used to tolerate a delay in receiving information from far-flung locations, most enterprises today demand that even the most remote sites be tightly integrated into the business processes.
Richer content. E-mail and other communications used to be text only, but today's workers think nothing of attaching 5 MB PowerPoint files and extensive Excel spreadsheets to their messages.
Increased interaction with voice and video. While networks used to serve up data-only files, more businesses now use their WAN links to carry critical voice and video communications.

The Solution

NetOut is focused on helping your company to optimize the WAN to improve application performance - increasing the available bandwidth across a link is part of that solution. By utilizing Juniper Networks application acceleration devices and techniques NetOut can enable greater throughput over the WAN. Juniper Networks Molecular Sequence Reduction (MSR) technique, stores patterns in memory and, when it sees a repeated pattern, sends a simple flag across the WAN rather than the full data pattern, reducing WAN traffic by 50 to 80 percent.

The Juniper Networks appliance supports a second reduction technique, Network Sequence Caching, which augments MSR compression with hard-disk-based pattern storage. The Sequence Caching technique stores longer data patterns and stores them for a longer period of time. This approach allows the appliance to eliminate redundancies even when a file has been modified or when it was last seen weeks previously. The Sequence Caching technique provides compression results as high as 80 percent to 98 percent.

With wan acceleration IT can cost-effectively increase the available bandwidth on their existing WAN links.

Reduce Costs

Despite the improving business climate in most enterprises, IT is still pressed to produce economic efficiencies and cost savings. This requirement-in direct conflict with IT's mandate to provide greater services to a growing user population-means IT has to make better use of existing resources rather than increase them.

Enterprise IT organizations continue to find innovative and creative approaches to cost reduction. To save money, these businesses can:

Avoid or delay WAN upgrades. With WAN costs being the second-highest IT expense after staffing, WAN optimization can have a significant payback, often with an ROI of less than nine months.
Improve application response times. By improving people's access to critical data and shortening the time needed to perform key tasks, IT can improve the business' core productivity and contribute to the bottom line.
Centralize or consolidate remote servers. The operational and capital costs associated with managing remote servers is very high, so reducing the requirement for those remote platforms can save significant funds.
Improve troubleshooting ability. The quicker IT can solve a problem, the more time the team has for advanced planning and other value-added tasks.

Consolidate Servers

Poor application performance across the WAN has driven the deployment of remote servers to provide e-mail and other critical file services in remote offices. While users enjoy the improved application response times that local servers provide, these remote servers create a range of IT problems. Chief among the issues are:

Regulatory compliance. More enterprises have determined that centralizing key data, such as e-mail records, is essential to adhering to regulatory demands.
Backup of key data. Relying on non-IT staff in branch offices to perform critical backup functions, such as nightly tape backups, has proven unreliable.
Patch and other software updates. Maintaining current software revisions and patch updates on a range of disparate remote servers is cumbersome, costly, and time-consuming.
Troubleshooting. Diagnosing and solving problems on remote devices takes more time and slows system recovery.

Server consolidation has its obvious benefits, and the move toward it is clearly underway, but IT organizations embarking on such a project must ensure that remote users will retain key application functionality. The fundamental WAN characteristics that slow application performance over WAN links haven't changed, so IT must address those limitations to ensure acceptable application performance when remote users access centralized servers. The Juniper Networks application acceleration platforms help maintain application performance as users in remote offices access file and other servers in centralized locations.
