RE: [Tipc-discussion] 64-bit processor node id

[Kevin K. He <he...@ya...>]

 
 It seems that we can't squeeze MAC address in the 12-bit node id.
 Then what will happen if two processor use the same node id ? Will
 TIPC automatically detect the collision and even automatically resolve 
 the collision by assigning unique node id to each other ? Does this
 sound a bad idea to implement if it's not there yet ?
