Q$3$ Fair Queueing Scheduler

$6$ Points

Consider a router with a $1$ Mbps egress link and fair queueing enabled. Three TCP connections are

transmitting over this link: A$,$ B$,$ and C$.$ At time $t=0,$ the queue is empty.

At time $t=1ms,$ a $250$B packet $($Packet $1)$ arrives for flow $A.$

At time $t=2ms,$ a $1000$B packet $($Packet $2)$ arrives for flow B$.$

At time $t=2ms,$ a $500$B packet $($Packet $3)$ arrives for flow $C.$

At time $t=3ms,$ a $250$B packet $($Packet $4)$ arrives for flow A$.$

At time $t=10ms,$ a $1000$B packet $($Packet $5)$ arrives for flow $C.$

At time $t=12ms,$ a $250$B packet $($Packet $6)$ arrives for flow B$.$

In what order are the packets transmitted? Enter the packets IDs, in order, separated by commas

and spaces. For example, answer $"1,2,3,4,5,6"$
