Some questions about LAN
Hi, all!!
I have some questions about LAN in ns.
1. Maybe the link in ns LAN is half-duplex, is it OK?
2. And I made LAN. There are 8 node and two of them are source node.
I attached tcp and ftp at each source node and I scheduled that
collision occured.
Source nodes transmit packet and sink node transmit ack and nack.
But I can't observe when collision occured,
when node retransmitted packets, when node transmitted ack and
nack..
How can I observe them?
3. This is very very important for me...
I must make star LAN, 10BaseT... Does ns support it? Or should I
program it?
