Make Sure You Get the Right Fit

tools garage silver peakHave you ever gone into your garage to build or repair something, but were unable to find the tools to do the job. I’ve experienced this more often than I care to remember. But, when I’m able to quickly find the tools I need, it’s not only very satisfying, it makes the project easier to do, and the final result comes out better.

When it comes to improving the performance of WANs and the Internet, it’s just as important to have the right WAN optimizer that fits the needs of your particular applications, allotted bandwidth and traffic volumes.

Just as different tools are necessary for the many different projects around the house – from the kitchen to the bathroom; enterprises too, have many such projects, including multiple sites, networks, applications and diverse remote users. While WAN optimizers are not a one-size-fits-all solution, virtual WAN optimizers can often fit the bill, as they can be implemented on-demand to appropriately fit each unique situation. These WAN optimization solutions can be quickly deployed, and easily migrated, or removed as needed.

To some extent, you can get a one-size-fits-all WAN optimization solution using a network-based WAN optimizer. For example, rather than only accelerating a few applications, network-based WAN optimizers support all traffic types, giving you complete control and visibility into all applications running over your network. This is super important, because every application has the potential to adversely affect your network.

To overcome the adverse effects of network bottlenecks, WAN optimizers can use various optimization technologies, including quality of service (QoS)/traffic shaping, deduplication, and real-time error correction.

QoS and traffic shaping help avoid the negative effects of network congestion by applying priority rules to give certain applications higher priority than others, and to ensure specific traffic is allocated over the appropriate network resources.

Deduplication inspects all traffic, storing the information as a local instance in the WANop appliance. By storing information locally, rather than sending it across the WAN, application performance and WAN utilization is significantly improved.

Data center-class WAN optimizers provide real-time techniques to address packet delivery issues common to shared WAN technologies, such as MPLS and IP VPN. For example, techniques such as Forward Error Correction (FEC) and Packet Order Correction (POC) overcome dropped and out-of-order packets by rebuilding packets in real-time instead of requiring retransmissions over the WAN. This helps to substantially reduce network congestion.

Whatever the size of the enterprise, with the right WAN optimizer, you can get the right fit!
