Do you WANt to optimize?

A few best practices to keep in mind throughout the selection and implementation process are:

-- Determine what type of files and data make up the majority of your traffic: User Datagram Protocol files such as VoIP, Trivial File Transfer Protocol (TFTP), and Internet Protocol Television (IPTV) do not tend to benefit from WAN optimization, but TCP and Common Internet File System -- e-mail and file transfers -- benefit greatly and tend to be the most common files.

-- Test current network utilization and capabilities: Determine how long it takes for a remote office to download a file from the central office, as well as if the backup window between data centers is too extensive. Decide if increasing bandwidth to enhance performance and decrease latency is necessary.

-- Ensure vendors are aware of network goals and needs: This will help them to provide relevant and effective input and offer implementation support.

-- Implement the WAN optimization solution in stages: Take a phased approach to limit the risk to the network, and allow for test and reassurance measures throughout the process. A phased approach will also help identify additional applications that may benefit from optimization.

-- Develop security policies: If not already in place, develop security policies that clearly outline the access and use of data and disposal processes for sensitive information.

WAN optimization is a burgeoning technology that can help a wide range of organizations improve the efficiency of their networks, boosting performance and reducing costs. It can also assist companies that seek to enhance their sustainability efforts by consolidating servers and data centers and reducing power consumption and energy bills. WAN optimization is a worthwhile investment yielding recognizable benefits any CIO can appreciate.
