Question

We have said that an application may choose UDP for a transport protocol because UDP offers finer application control (than TCP) of what data is sent in a segment and when.

a. Why does an application have more control of what data is sent in a segment?

b. Why does an application have more control on when the segment is sent?

Answer 1

UDP has more control as compare to TCP in terms of data and time.

a. In terms of data, an application has more control in UDP as compare to TCP, in terms of confidentiality and security of Data. As UDP use the process of encapsulation to secure the information, this will cause that UDP will know that what data is sent.

b. UDP has the ability to control the flow of data and traffic congestion control, while TCP has no congestion control which causes extra delays in application. Due to this reason UDP has better control over time to send the data.

We can say that, UDP has better control than TCP.
