Question: Consider the problem of implementing timers. Selective Repeat does not resend all packets on timeout, so it must timeout packets individually. However, in an implementation

Consider the problem of implementing timers. Selective Repeat does not resend all packets on timeout, so it must timeout packets individually. However, in an implementation we are likely to only have one hardware timer. How might we solve this problem? What would happen if we re-start the timer every time a packet is sent? What would happen if we re-start the timer when the oldest packet is ACKed?
