Compared to TCP, UDP is a simpler message-based connectionless protocol. Connectionless protocols do not set up a dedicated end-to-end connection. Instead, communication is achieved by transmitting information in one direction from the source to the destination without verifying the readiness or state of the receiver. However, one primary benefit of UDP over TCP is the application to the Voice over Internet Protocol (VoIP), where latency and jitter are the primary concerns. It is assumed in VoIP UDP that the end users...
