asymmetrical network analysis definition

uses fiber cables that run from the telephone exchange to roadside cabinets, which then connect to standard phone lines at business premises via copper cables to deliver broadband.uses a combination of fiber and copper cables.Other examples of asymmetrical circuits include the following: It is asymmetric because it uses most of the channel to transmit to the user (downstream) and only a small part to receive from the user (upstream). ADSL technology transmits digital information at a high bandwidth on existing phone lines. What is an example of asymmetrical communications?Īsymmetric Digital Subscriber Line ( ADSL) is an example of asymmetric communications. How a company uses the internet, its size and use case, among other factors, determine whether asymmetric or symmetric communication is best for an organization. In these situations, asymmetrical communications improve internet performance for end users. So, a symmetric connection would be inefficient and a waste of limited telecommunications ( telecom) resources. Similarly, when users are just browsing the web, they're downloading more information than they're uploading.

In this environment, it would not make sense to install the sophisticated hardware necessary for a broadband satellite uplink. However, upstream data might be limited to low speeds, since it consists mainly of new content requests by the subscriber, which contain fewer bytes compared to downstream data. In many web browsing applications, this may consist of relatively large graphics, sound, multimedia and HyperText Markup Language files. In this case, the downstream data might flow at extremely high speeds. In this type of asymmetric communications, the hardware is simple, consisting of the following: Consider an internet connection, in which downstream data from an internet server to the subscriber flows over a broadband satellite downlink, while upstream data (user to server) is sent over a twisted pair telephone line.
