![]() ![]() IP Header is usually 20 Bytes (160 Bits) long.Īssuming that this customer uses 100 Byte payload, each IP Packet will now be 120 Bytes long.And that 1MB message will have to be broken down into 10,000 payload pieces. This is where the information likethe source IP Address, the destination IP Address and additional information about thepayload is included. EachIP Packet also contains an IP Header. Some have smaller size, so the message will take moreIP Packets to transmit while others may have larger size which needs fewer IP Packets. The size of these packets is usuallydetermined by your Local Area Network. The device that sends this email will break down the message into smaller pieces and packagethem into what are called IP Packets. ![]() The channel needs to not only transmit thepayload but also some addressing details like where it is coming from and where it isdestined to. But it will actually takelonger as the total information that needs to be transmitted is more than 1MB. You have Ethernet8.0 Mbps service and need to transmit an email which is exactly 1MB in size You mayexpect it will take exactly 1 second to transmit that message. Throughput is the maximum amount of communication or messaging that can betransmitted through a communication channel during an elementary unit of time, usually,in a second.ĭepending on the type of channel, the addressing mechanism used in that channel,the type of messages are being transmitted and how secure the transmission needs tobe-along with physical attributes like temperature, humidity and signal-to-noiseratios-actual measured throughput will vary. As files todownload become increasingly larger, the highest data transfer rate is most desirable. Transfer rate is speed at which data can be transmitted between devices.Mbps is theindustry-standard used by ISPs. One megabit per second equals 1 million bits per second. Mbps transfer rate = megabits per second transfer rate. There are 8 bits in a byte,so we would divide kbps by 8 to get KB/sec transfer rate. Kbps transfer rate = kilobit per second transfer rate. If achieving optimal upload speed is a concern, consider DedicatedInternet Access. Upload speed is even more important if you are operating aserver at your location. This is important for applications like VoIP, on-line gaming andother interactive programs. Upload is the measure of how fast content is delivered from your computer or localarea network to others on the Internet.įor businesses or power-users, download and upload speed should match or atleast be very close. Please readthe definitions and examples below to learn more about these factors.ĭownload is a measure of how fast your connection delivers content to your computeror local area network. Throughput problems in yourlocal area network, IP or access overhead, and network design all play a role. There are many factors that impact your speed test results. What is “Throughput” and what factors affect my results? Try rebooting your modem or router and then running the test again.Try using a wiredEthernet connection instead. When using a wireless connection, there may be wireless interference.Be sure to stop any downloads or programs that may be using your connection whilerunning the test.But before you do, be sure to read this site's Comment Policy.

While I’m not recommending Speakeasy - I know nothing about it - I do recommend this test. (It’s not in my area, but then again, there’s only one non-dialup option available for my home and you’ve seen the results.) I can just about pin the speed needle with my DSL connection at the office.) At the end of the test, Speakeasy plays a little advertisement and offers access to a search feature where you can see if their service is available in your area. (Now you can see why I don’t want to move my office back home. Here’s an example of what my terrible home Internet connection looks like with the upload test in progress. The Speed Test displays your results graphically using a speedometer-like meter. To take the speed test, choose the server nearest you. Take the Speakeasy Speed Test and test your connection speed! By measuring the download and upload rate from the following locations you are able to accurately judge your current line throughput or internet connection speed. You can check it for yourself.Īlthough there are many bandwidth testers on the Web - your ISP probably provides one - I use one called Speakeasy Speed Test: When you set up your Internet connection with an ISP, you don’t need to believe what they tell you about bandwidth speeds. ![]()
