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

a)

In TCP protocols:

  • If the send the segment application then data is not assigned directly.
  • Then data store in buffer then decide to connect the segement.
  • So,the application does not have more control to sent data in  the TCP protocol.

For UDP protocols:

  • If the send the segment application then data is assigned directly
  • Then the data in the segment is then sent.
  • So, the application has more control to sent data in the UDP protocol.

b)

  • In TCP protocol cannot expect the time between sent data and arrived data. So, an application does not have more control on when the segment is sent in TCP.
  • n TCP protocol can expect the time between sent data and arrived data. So, an application have more control on when the segment is sent in TCP.
