Asynchronous and Synchronous Connectivity

Internet connections have to send information in two directions – sending requests from clients up the internet and then downloading the response. Many internet connections such as ADSL and satellite are asynchronous, which means their upload and download speeds are different. For example a standard ADSL connection may have a download speed of 18Mbps but the upload speed will only be around 0.75Mbps. For events in most cases it is important to have synchronous connections, where the upload and download speeds are the same, because these days there is just as much requirement for uploading as there is for downloading. Often if an asynchronous connection is used the upload speed will rapidly become a bottleneck impacting performance for everyone.
