Hello all, Assume I have the following connection scheme, n0-----n1------n2 all the links is duplex links. if I have attached two agents on n0 and n2, and create a simplex connect from Agent_n0---> Agent_n2, then I called Connector::send(p,0) method to send pkt downstream one hop. My question is, (1) Is the downstream one hop refered to n1 or n2? Kind of confused, any clarification is appreciated. Tks, shuqian
