hi, I was wondering whether LL (link layer) implemented in current version includes timer mechanism.
I plan to have two node connected to LAN and have them send data with acknowledgment mode of LL. I could not find a hint in the latest ns-manual whether a retransmission request is abandoned once there is not reply in some predefined time? Example: host1 <==========================> host2 (sender) ethernet (receiver) Once host2 detects a missing frame, it requests host1 to resend the concerning frame. However it would not wait forever for retransmission of this frame. After a timer is expired, this frame is marked as missing. This is how standard (RFC) says. I do not know whether something like is enabled in current version of ns2? Your thoughts are much appreciated. Regards, -- Luqman
