“Tunnel Vision” is a medical condition involving a loss of one’s peripheral vision, but most also know the term as a description of a certain mentality: the tendency to focus on a narrow or limited point of view or perspective.
Most, if not all, organizations have many applications going over WANs. They may even have hundreds of very important applications running over public and shared networks to support their customers, subscribers, partners, and employees. Yet many organizations fall short when it comes to making sure their networks are able to keep ALL of their applications running fast and reliably — instead of seeing the ‘big picture’, these organizations seek to accelerate their application delivery by using networking solutions that only support a handful of applications.
The fact is, many of today’s applications are the cause of network underperformance. Application delivery can become corrupted because of lost and out-of-order packets. These same applications can also add undue congestion and latency with excessive transmission turns and unnecessary, repetitive data going over the network.
WAN optimizers are designed to accelerate network traffic and allow organizations to get more complete utilization of their bandwidth. But many of them don’t solve congestion, latency, and packet loss for all IP traffic — by their design, application-based WAN optimizers support a limited set of applications. However, network-based WAN optimizers handle bandwidth, latency, and packet loss in real-time at the network layer to support virtually all applications, regardless of transport protocol. This means TCP applications, applications running over UDP, and proprietary or encapsulated protocols, all run faster and more reliably.
Applications such as voice and video typically run over UDP, and VDI applications can run over multiple protocols, such as TCP, PCoIP and UDP. Because several protocols run over the same network, many organizations struggle with the increased use of diverse traffic types. This is why it’s important to accelerate all traffic, regardless of the protocol.
Don’t let your network suffer from “tunnel vision” – choose a WAN optimizer that supports the network layer to take care of the big picture.
