File Size Download Calculator

How long will will my file transfer take?

Use our download calculator to estimate file download or transfer speeds. We offer this tool to assist in determining which connection speed meets your needs. Actual transfer speeds will be slower than these times due to latency. If the results of your file transfer are in the hours, you may want to consider looking at T1 line providers available in your city.

Measuring the maximum data throughput rate of a communications link is a typical method of performing a measurement of the download / upload rate to transfer a 'large' file and measure the time taken to do so. The throughput is then calculated by dividing the file size by the time to get the throughput in megabits, kilobits, gigabits, terabits or bits per second. Another factor which effects file transfer speeds is latency.

In fact, there are many overheads in transmission that mean the calculated 'effective' throughput does not reflect the true situation. Normally throughput and latency are opposed goals. To improve latency you typically want to increase how much the computer checks to see if you are trying to interact. This checking overhead slows you down. However there is one very common exception to this rule. Network protocols and programs tend to synchronize both ends regularly. If these synchronizations are slow, then throughput can suffer.

Other Factors

Throughput in IT terms, this is the speed at which a computer or network processes data end to end. It therefore is a good measure of absolute performance, and we frequently will see internet connections rated in terms of how many bits they pass per second (bit/s). However it is a very bad measurement of perceived performance, which is mostly based on how quickly it responds to you. Responsiveness has far less to do with throughput than latency.

Latency is a measure of amount of time between the start of an action and its completion, whereas throughput is the total number of such actions in a given amount of time.

T1 Access to the Web Written by - Garry Wolfe, Staff Writer

T1 access is a digital transmission service that can be used for carrying voice and/or data. A T1 connection is sometimes referred to as a "dedicated service" as the service is delivered to and from the customer premise from the CO (Central Office) without combining it with other traffic. A T1 connection is established by providing a "loop" or wire from the users premises to the CO where the service provider has equipment. Part of the cost of a T1, DS1, T3, DS3 is the "loop charge" or the monthly rental fee for the wire that is rented from the local phone company. Once the connection reaches the CO it can access the carriers network and reach any destination. 

T-1 provides high speed, point-to-point digital transmission line (up to 1.544 Mbps). This can be used as a single high-speed data channel or it can be split into 24 channels and allocated to either voice or data applications. It is widely deployed and readily available in most regions and although the service is not diminished by distance from the CO, the price is sensitive to distance. This is due to the rental of the loop from the LEC (Local Exchange Carrier). T1 is currently the most common way that large companies connect their LAN to the rest of the world. 

Are you ready for T1 service? You may be ready if you have critical services that need a reliable connection to the internet. If you run ASP services, host e-mail servers or web servers, have over 20 people accessing the internet or use video on demand you should consider T1 access. While more expensive that DSL, T1 access is made to support the above applications. Also remember that when you begin shopping for T1 service you should partner with someone who will act as your agent and represent your best interests. Consider using a broker or agent to help you with your search and cut through some of the industry lingo to help you get exactly what you need.
