WAN optimization technology has been around for some time now, but in an environment where users are demanding more and more heavy bandwidth applications, many companies are finding that their network creaking under the weight. There is a puzzle facing the company - to increase bandwidth availability or to invest in making more efficient use of network bandwidth. In essence, this is a simple trade-off between doing nothing and are struggling with the problem by adding more bandwidth, or into some form of acceleration and network optimization.
In the first case, the option to maintain the status quo and come up with what you have is a very expensive solution. Doing nothing in this case is still incurred heavy opportunity cost in terms of lost production and the inability to seize business opportunities, because workers can not answer them promptly. Option is to upgrade the bandwidth availability, but as we all know it is expensive . Increasing the bandwidth allocation without addressing how the current source is used is also costly in terms of opportunity cost and operational option is to consider WAN. Problem with WAN optimization is that the decision is often perceived as "a new project," and that the incurring incremental costs.
That said, WAN optimization has some very powerful financial and business arguments up. The first argument is that the WAN optimization has a very short payback period. This is typical of the period of repayment in the last 9 months, after which the company is saving costs in the future. WAN optimization is also relatively short project from start to implementation. Although there are devices that can be used to accelerate network traffic and provide effective load balancing, most of the implementation involves looking at existing traffic. Much of the traffic on the network is duplicated or redundant, for example CIF protocols are very "chatty", but a lot of back and forth movement of data is not necessary, but it is taking up bandwidth.By with emphasis on the gossipy networks and redundant protocol, a large part traffic can be eliminated from the network example of making better use of existing resources in the patch.
Consider a remote office with 100 users, Microsoft releases security patches to be downloaded to all machines. A typical scenario is for users to report top and get a message directing them to download a patch from a central server this results in 100 downloads over the WAN a. Update method is that a user download the patch, and then have it stored locally. Subsequent patch download, then they are made from local storage, not including the placing of traffic on the network
It is also typical for a large portion of the existing bandwidth to be released after WAN optimization is carried out. This eliminates the need for further purchase of bandwidth, but it also opens the door for the implementation of the deployment of bandwidth hungry to drive business productivity and further cost savings, such as VoIP solutions.
