Dear Networkers,
   As you may know, many applications need multicast communications and
broadcast communications. However, todays hypercube computer, N-cube/10,
for example, does not have such functions. You have to effect this by 
sending a separate message to every other nodes. This, in fact, includes
too many duplicated transmissons, since some nodes have to forward this
same information many times. 
   I know some people have done some research in this area, such as 
the Yale University, but I wonder why these algorithms are not implemented
in the commercial products now, although such algorithms were ready several
years ago. Can anyone out there give an answer to this? Does it make sense
if we try to implement these algorithms now?
