UDP generates less overhead than other transport protocols and is highly desirable for real-time broadcasting of multimedia such as audio, video, and network gaming data. However, due to its lack of guaranteed delivery and sequencing, it creates additional work for developers, and thus the pros and cons of its use must be considered on a case-by-case basis.
Java supports UDP in the form of the DatagramSocket and DatagramPacket classes. In order to send or receive packets, an application must bind to a local port using DatagramSocket. The application creates a DatagramPacket with a sufficient buffer ...
