a node connects to a switch and switch in turn connects to all other nodes. hence in effect when a node transmits it is the only one transmitting on that wire and hence gets the full bandwidth in its transmit wire (eg in 10BaseT). (csma/cd not applicable here,....right ? because it is the only node transmitting on it transmit wire connecting to the switch)
But what if two or more nodes are trying to send packets (rather frames) to one particular node. say two frames from two different nodes, destined for node A arrive in the switch and now how does the switch send the frame (frames), or which frame would it send to node A ? and what happens to the other frame ? is it discarded by the switch or is it quequed in the memory and is sent next. how does it work ? csma/cd would apply here and bandwidth would have to be shared in such a case ??? __________________________________________________ Do You Yahoo!?
