Two users, one using Ielnet and one sending files with FIP, both send their traffic out wa router R$.$ The outbound link from R is slow enough that both users keep packets in R$\text{'}$s qu Discuss the relative peformance $($i$.$e$.$ how many Telnet packets are sent per FIP packet$)$ seen by the Telnet user if R$\text{'}$s quecung policy for these two flows is

$($a$)$ Round robin service

$($b$)$ fair queuing.

$($c$)$ Modified fair queuing, where we count the cost only of data byes and not IP or TCP headers

Consider outbound traffic only. Assume Ielnet packets have $1$ byte of data, FTP packets have $512$ byes of data, and all packets have $40$ bytes of headers.
