At first I had wanted to have unused bits in the message formats in order to allow for students to do extensions on the protocol. Also, adding the unused space at the end of some fields and not others would cause trouble for anyone trying to send a structure directly. After discussing with the professor, we have decided that any unused space between fields (ie. padding after fields) is too confusing. Consider all message formats with every field back-to-back -- no padding between. (And no space for extensions). This means messages have the following size: Interest, Group update request, Withdraw of interest = 41 bytes. Group update reply = 37 bytes + additional fields Segment update request = 35 bytes Segment request = 37 bytes Segment reply = 39 bytes + segment For more details, please see http://vir.isi.edu/csci551/index.php/ProjectA3#Tracker-to- Peer_Communication The class peers now understand/talk only these message formats. Please let us know if you have any questions. I apologize for the confusion, gen
