Hi all, I am doing crossing layer handoff between SIP application layer and MAC layer.
The SIP module is for wired link, implemented as SIPUT/Agent． but the MAC layer module is for wireless link, implemented as MAC/Agent. Now both their packets are sent to Agent. My question is： How did the Agent know which packet should be given to SIPUT/Agent, and which packet should be given to MAC/Agent?? Any clue is really appreciated! Thank you in advance. -- Best Regards! Vivid Zhang ******************************************** ** Enjoy your time! ** Enjoy your life! ** Email: [EMAIL PROTECTED] ** Tel:+86-10-6228-4442
