Differences between symmetrical and asymmetrical connections

conexiones simétricas

Symmetrical connections are those which have the capacity to upload and download information at the same speed. In addition to send and receive data at the same time. All that without the signal decreasing its quality. This is possible thanks to the optical fiber, since its way of functioning facilitates the circulation of information in both directions.
Many times we find that the offer is about asymmetric connection at higher speed or symmetric at lower. The disadvantage of the first one is that the uploading speed is usually far too slower than the downloading one.

At the beginning, connections were asymmetric. That is to say, the downloading speed used to be much faster (up to 90%) than the uploading speed. And, although, these types of connections still exist, symmetrical ones are imposed due to market demands.

The birth of symmetrical connections is due to the need of the users. A priori, Internet users used it mainly to download information. Therefore, the connections that were initially offered, gave priority to the download speed versus the upload speed.

Symmetrical connections facilitate the “cloud computing”

When the optical fiber appeared, the simultaneity of sending and receiving information was facilitated. The “cloud computing” raises that the information won’t be physically with the user. With this way of working, all the data is in the cloud, so the internet user should download and upload information constantly.
This procedure is, increasingly, being implemented in academic and work environments. Sooner than later physical supports will give way to the storage of information in the cloud.
Although asymmetrical connections are still offered (and they are still very useful), we can’t turn our back on the trend. In the not-too-distant future, symmetric connections will be implemented for all users, and we will be there.
