Hello folk!
I'm a student and I'm doing a research on the NAT traversal problem in order to achieve a direct p2p communication.
After
the study of the relative RFC and Drafts, I've come to a solution for
my project, and now I'd like to use the pj_libraries for NAT traversal.
I've studied yet the version 0.8 of pjstun_client (in order to perform
NAT detection), but now I've to go further and try to traverse the NAT.
I
wished to use UDP Hole Punching, and ICE seems to work even better
because realize a UDP hole punch with the exchange of both local and
mapped address: is all right or I'm wrong?
My probem is that I don't know how to start using ICE after performing the detection.
Moreover,
thanks to the changes made in the APIs version 0.9, I need to modify
the first part of the code... and a lot of attributes are lost (like
PJ_STUN_ATTR_REMOTE_ADDR, PJ_STUN_SET_ACTIVE_DESTINATION_REQUEST,
PJ_STUN_ATTR_REQ_PORT_PROPS..).
Would you please clarify me those aspects?
Could anyone explain me how to proceed?
I think that:
I've to start with the pj_ice_strans_create(), and then call the pj_ice_strans_init_ice() and finally pj_ice_strans_start_ice().
Is that all right?
And what about the pj_ice_strans_cfg_default() and pj_ice_strans_send_to()?
Shall I've to call the pj_ice_strans_cfg_default() from within the pj_ice_strans_init_ice()?
I hope anyone would clarify me the libraries...
