[ns] Queue in Bytes

[Adnan Huremovic]

Hello,
Do you know what is the size of queue when specified in packets?  For example, if I put

$ns duplex-link $n4 $n5 2Mb 20ms DropTail

$ns queue-limit $n4 $n5 48



and have in the same time connections with different packet sizes (1000 i 1040 Bytes). What is the size of my queue in bytes? 



Thanks, Adnan
