3 Memahami Port Protokol TCP dan UDP menggunakan port untuk mengumpulkan data dari komputer jaringan. server P o r t TCP Client app app app app port port port port TCP or UDP Packet Data port# data

4 Memahami Port Port sebuah terminal virtual yang digambarkan dengan sebuah Nilai (integer) sebagai tempat keluar masuk data Beberapa port telah direkomendasikan sebagai sebuah services antara lain : ftp /tcp telnet 23/tcp smtp 25/tcp login 513/tcp User level process/services generally use port number value >= 1024

5 Sockets Sockets provide an interface for programming networks at the transport layer. Network communication using Sockets is very much similar to performing file I/O In fact, socket handle is treated like file handle. The streams used in file I/O operation are also applicable to socket-based I/O Socket-based communication is programming language independent. That means, a socket program written in Java language can also communicate to a program written in Java or non-Java socket program.

6 Socket Communication A server (program) runs on a specific computer and has a socket that is bound to a specific port. The server waits and listens to the socket for a client to make a connection request. server Connection request port Client

7 Socket Communication If everything goes well, the server accepts the connection. Upon acceptance, the server gets a new socket bounds to a different port. It needs a new socket (consequently a different port number) so that it can continue to listen to the original socket for connection requests while serving the connected client. server port port Client port Connection

8 Implementasi PHP Sockets
Server ServerSocket(8000) Output/write stream Client Input/read stream Socket(“ ”, 8000) It can be host_name like “informatika.itp.ac.id”

9 Contoh Implementasi PHP dalam Pemograman Sockets
Buatlah file : - stream_server.php - stream_client.php - formsockclient.php Buka browser, lalu aktifkan stream_server.php, buka browser lain aktifkan formsockclient.php

10 Tugas Kelompok Buatlah program Chatting LAN / program Chatting berbasis pemograman jaringan Buatkan laporan hardcopy atas tugas ini. Masing-masing kelompok akan dilakukan pengujian atas tugas nya.
