- Properties
of TCP
communication:
- Reliable:
- Data sent using a TCP socket is received once and in the transmission order
- Stream oriented
- Data
transmitted using
TCP can be
received in
different chunk sizes
that transmitted !!!
Graphically:

- Note for CS450 students:
- A TCP socket behaves
exactly the same
as a UNIX pipe/
Except that:
- You use one (= same)
descriptor for
reading/writing !!!
I.e.:
- A TCP socket is bi-directional
- You use one (= same)
descriptor for
reading/writing !!!
- A TCP socket behaves
exactly the same
as a UNIX pipe/
- Comment:
- TCP sockets are
the most commonly used
communication end point
in network programs
because:
- Retransmissions
(to provide reliablity)
is handled by
the TCP protocol itself.
(So the programmer can focus on programming the application itself....)
- Retransmissions
(to provide reliablity)
is handled by
the TCP protocol itself.
- Virtually every network program is written using TCP sockets
(UDP sockets are only used by network research projects that experiment with new network transmission algorithms)
