Questions tagged [multiplexing]

In telecommunications and computer networks, multiplexing (also known as muxing) is a method by which multiple analogue message signals or digital data streams are combined into one signal over a shared medium.

In telecommunications and computer networks, multiplexing (also known as muxing) is a method by which multiple analogue message signals or digital data streams are combined into one signal over a shared medium.

The aim is to share an expensive resource. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications.

In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910.

Why does app using HTTP/2 only establish one TCP connection?

I understand that HTTP/2 multiplexing solves head-of-line blocking problem in HTTP/1.1. However, head-of-line block still exists in TCP protocol. Even if requests are sent at the same time in application layer, the messages still need to be sent one…
