Multiplexing and Demultiplexing
Explore how the transport layer handles multiplexing and demultiplexing to deliver network packets to the right applications. Understand how port numbers enable multiple processes to communicate concurrently and how data streams are managed efficiently.
What are Multiplexing & Demultiplexing? #
End-systems typically run a variety of applications at the same time. For example, at any given time a browser, a music streaming service, and an email agent could be running.
So how does the end-system know which process to deliver packets to? Well, that’s where the transport layer’s demultiplexing comes in.
