Some reviewers have asked about the use of “MB/s” as a measure of transfer speed. In the Guccifer 2.0 NGP/VAN Metadata Analysis report. “MB/s” refers to Mega Bytes per second where “Mega” is one million (1,000,000). Some reviewers have confused this notation with “Mb/s”, or mega bits per second often quoted by ISP’s. Those two measures of transfer can be confused with each other, and there are articles on the Internet that discuss this topic, for example here and here.
This handy calculator will let us do all sorts of what if comparisons and that particular “calculator” link will convert 22.6 MB/s (the estimated transfer rate cited in the report) into the following chart.
As you can see it is at about the 80% level of a 1 Gb/s local area network (LAN), which is typical of many wired enterprise/SOHO wired networks, but as far as “carriers” go, you’re up there in the stratosphere. OC stands for “Optical Carrier”, as in “optical link”, fast but expensive. For the gory details, see this Wikipedia article on Optical Carrier transmission rates.
Let’s talk transmission overhead. Going from MB/s to Mb/s when we’re referring to network transfer rates should also account for communication overhead. Basically, when you send stuff around on network, you need to break it up into packets and each packet has a header, maybe a trailer, and all that is overhead. From the Wikipedia link, you’ll see this statement for OC-3: “OC-3 is a network line with transmission data rate of up to 155.52 Mbit/s (payload: 148.608…Read More
