Socket


In communications between network required a interface between program connective application of communications some protocol ( program applications interface, API). In this case API represent interface which look to all programmer. In consequence, used API types very depend on system language and operation of programming used. API to be studied to work for network in system operate for UNIX by using language of programming C. In fact for the scope of this is there are more than one API type, but to be included here is Barkeley Socket Interface. To the transfer of having the character of connection-oriented process that happened is : first time server put into effect, then followed by client which later; then will conduct connection to server. As for its illustration shall be as follows :

















Socket Address

System Call related to networking at BSD always addressing its, it to a structure of address of socket ( address socket). structure defined in file. header .


System Call Socket

Some elementary call system which used to conduct programming network :

a. socket system call

b. bind system call

c. connect system call

d. listen system call

e. accept system call


Definition Protocol

Server run at port 1500 and listen at port 1500, later then client run for connection to port 1500. After connection formed by client deliver and address place port of listen – its to server. Later then after server accept the information the of client hence server make connection to client pursuant to information port and address of listen client. After connection formed by hence server deliver ack to client and from side of client accept ack delivered by server.

Hereinafter side of client ask and user name of password. After and user name of password, hence client deliver request to server to conduct file upload. Later then server pass in client to the transfer of file. After client accepting the permission hence client the transfer of file to server. Later then after is altogether sent, hence client deliver ack that transfer of file which is the conducting of have.
