推 kchiu:restart timer吧220.136.220.131 04/22
推 kchiu:因為base已經+1了...所以timer要重設220.136.220.131 04/22
near bottom of page 15 (title: GBN: sender extended FSM)
rdt_rcv(rcvpkt) &&
notcorrupt(rcvpkt)
-----------------------------
base = getacknum(rcvpkt)+1
If (base == nextseqnum)
stop_timer
else
start_timer
^^^^^^^^^^^
start_timer means "keep timer running" or "restart timer"?
