[ns] A problem about the length of a queue

[Teerawat Issariyakul]

Well, what you can do is to write a function, say lengthb()) in class
PacketQueue (there is a variable pq_ of class Queue). In this function,
determine the number of bytes of each packet from head_ to tail_ of a
PacketQueue object and returns the total number of bytes.

I posted how to determine the packet size at

For more information about Packets, see Chapter 8 in the following book
from Springer:

T. Issaraiyakul and E. Hossain, "Introduction to Network Simulator
NS2", Springer 2008.

hi everyone!

In NS2, the length of a queue is always caculated as the number of
packets in it.But we know that the size of a packet always differs from
another's. In my opinion, in practice the length of a queue should be
measured by the size, rather than the number, of all packets in it.
In my simulation, i need to simulate the length of the Q as the total
size in it,how can i achieve this?
thanks in advance!
