jbkim | 0:2513c6696bdc | 19 | * @brief WIZnet socket APIs are based on Berkeley socket APIs, thus it has much similar name and interface. |
jbkim | 0:2513c6696bdc | 20 | * But there is a little bit of difference. |
jbkim | 0:2513c6696bdc | 21 | * @details |
jbkim | 0:2513c6696bdc | 22 | * <b> Comparison between WIZnet and Berkeley SOCKET APIs </b> |

jbkim | 0:2513c6696bdc | 35 | * </table> |
jbkim | 0:2513c6696bdc | 36 | * There are @b bind() and @b accept() functions in @b Berkeley SOCKET API but, |
jbkim | 0:2513c6696bdc | 37 | * not in @b WIZnet SOCKET API. Because socket() of WIZnet is not only creating a SOCKET but also binding a local port number, |
jbkim | 0:2513c6696bdc | 38 | * and listen() of WIZnet is not only listening to connection request from client but also accepting the connection request. \n |
jbkim | 0:2513c6696bdc | 39 | * When you program "TCP SERVER" with Berkeley SOCKET API, you can use only one listen port. |
jbkim | 0:2513c6696bdc | 40 | * When the listen SOCKET accepts a connection request from a client, it keeps listening. |
jbkim | 0:2513c6696bdc | 41 | * After accepting the connection request, a new SOCKET is created and the new SOCKET is used in communication with the client. \n |
jbkim | 0:2513c6696bdc | 42 | * Following figure shows network flow diagram by Berkeley SOCKET API. |
jbkim | 0:2513c6696bdc | 43 | * @image html Berkeley_SOCKET.jpg "<Berkeley SOCKET API>" |
jbkim | 0:2513c6696bdc | 44 | * But, When you program "TCP SERVER" with WIZnet SOCKET API, you can use as many as 8 listen SOCKET with same port number. \n |
jbkim | 0:2513c6696bdc | 45 | * Because there's no accept() in WIZnet SOCKET APIs, when the listen SOCKET accepts a connection request from a client, |
jbkim | 0:2513c6696bdc | 46 | * it is changed in order to communicate with the client. |
jbkim | 0:2513c6696bdc | 47 | * And the changed SOCKET is not listening any more and is dedicated for communicating with the client. \n |
jbkim | 0:2513c6696bdc | 48 | * If there're many listen SOCKET with same listen port number and a client requests a connection, |
jbkim | 0:2513c6696bdc | 49 | * the SOCKET which has the smallest SOCKET number accepts the request and is changed as communication SOCKET. \n |
jbkim | 0:2513c6696bdc | 50 | * Following figure shows network flow diagram by WIZnet SOCKET API. |
