Network Transport Layer: Functions & Protocols Explained
Transport Layer Functions
The primary function of the transport layer is to facilitate reliable communication between communicating endpoints. This involves tracking errors and managing flow control (typically between the source and destination) to prevent data loss.
Beyond these core functions, the transport layer can multiplex multiple application-level connections into a single network connection. This reduces costs, for instance, when a service provider charges based on connection time and count.
