Rex, First of all thanks for prompt reply. Second of all let me ask you this to clearify further. How would a MAC layer look into the MAC header if it is the one to put the MAC header onto the packet coming from upper layer (Network layer)? I am talking about the packet that a node sends out to other node. I am not talking about MAC layer's function after it "receives" the packet from other node. Please let me know how a MAC header is created by a node. It has to some how look at the IP header of the frame coming from above layer in order to append the MAC layer header (e.g. Destination MAC address) to the packet. Therefore I asked about the ARP process in MANETS as well because if a node doesnt know about the MAC address of the destination node how would it proceed. Thanks alot Fariha >===== Original Message From Rex Buddenberg <budden@nps.navy.mil> ===== >On Mon, 2006-04-24 at 12:33 -0500, fxbaloch wrote: >> Ali, >> >> Can you help me with these queries.
