<html><div style='background-color:'><DIV class=RTE>A Quick Description</DIV> <DIV class=RTE>--------------------------</DIV> <DIV class=RTE>The new version of Node, 0.31, which is hopefully going to be released within this week, features many new characteristics many of which are using a new protocol developed by Node Team, called NDC. </DIV> <DIV class=RTE>The NDC protocol allows two Node clients to connect to each other over TCP/IP and exchange some special messages called Packs. This can be very useful sometimes, as it allows the program to send data that is not usually sent over IRC and wihout the need of a server.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Establishing a Connection</DIV> <DIV class=RTE>----------------------------------</DIV> <DIV class=RTE>An NDC connection is automatically established between two users who are having a private conversation and both are using Node. This is done over CTCP with two different messages, the first one(NDC*) sent by the client who wants to start a connection and the other(NDC), sent as reply, which includes the IP of the client which sends it. After these two packs are exchanged a direct connection is established between the two clients.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Features</DIV> <DIV class=RTE>------------</DIV> <DIV class=RTE>The current features are not many, but we are planning to make them more. For version 0.31, we will include the typing message feature and the avatars feature. The first feature, typing message, allows users to see if the person is typing a message. The second one, avatars, allows each user to choose a display picture which other users will be able to see later.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Details</DIV> <DIV class=RTE>---------</DIV> <DIV class=RTE>For details about the exact data and packs exchanged after a TCP connection is established, please refer to NDC specification, available at <A href="http://node.sourceforge.net/?view=ndc-specification&head=doc/dev">http://node.sourceforge.net/?view=ndc-specification&head=doc/dev</A>.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>Our Plans</DIV> <DIV class=RTE>-------------</DIV> <DIV class=RTE>For future versions, we are planning to include more features based on NDC. We have in mind audio and video conversations. If you have any other ideas please fell free to post suggestions or comments.</DIV> <DIV class=RTE> </DIV> <DIV class=RTE>(dionyziz)</DIV></div><br clear=all><hr>Add photos to your e-mail with <a href="http://g.msn.com/8HMBEN/2746??PS=">MSN 8.</a> Get 2 months FREE*.</html> |
