| 4 | |||
| 5 | * Make a program which will listen for multicast message. |
||
| 6 | 5 | Greg Burri | * It must be work between sub-networks (vlan). |
| 7 | 2 | Greg Burri | * It should be also able to send. User can type a message and all other peers will print it when it is sent. |
| 8 | 1 | Greg Burri | * Test it with some computers. |

| 10 | 3 | Greg Burri | h2. Qt and UDP multicast |
| 11 | |||
| 12 | There is no support to UDP multicast in QT4.5 according this bug issue : http://www.qtsoftware.com/developer/task-tracker/index_html?method=entry&id=57952. |
||
| 13 | An alternative is to use a broadcast address with _QHostAddress::Broadcast_. It will only work with IPv4. |
||
| 14 | |||
| 15 | It's possible to use UDP multicast only with the low-level API. This solution is OS dependent and will not be accepted. |
||
| 16 | |||
| 17 | For the moment the broadcast alternative will be used. |
