Determine Bandwidth Capability and speed of data transfer
Posted on 2012-09-04
I am trying to find the best way to calculate how long it will take to transfer email data from one server to another. I use an program to convert/transfer the data. This program is run on a workstation. It logs into the source program, it grabs an email message, it works on it via the workstations TEMP directory, and then it places the message into the target application.
When calculating how long a transfer (migration) will take, I usually suggest setting up a source account with 1Gb of Data, and then time the transfer. Once the transfer is made, we can see how long it takes to migrate 1Gb of messages. Then, we can calculate how long it will take to migrate an entire server's worth of email messages.
Often, the limiting factor is the speed of the network or the WAN link.
What is a good way to determine how long it will take to move/transfer data from one computer to the next based upon the network connection and/or the WAN link? This is where I am unsure of what to do. For example, many times people are using a cable connection, a DSL link, a T-1, or something else. I don't know how to calculate those network connections.
Please assist me in getting a grasp on how the network connection and the WAN links would affect data migration, and how to determine the transfer rate given the different connection speeds and using the IP Protocol on a Windows computer.
