Group,
Quick question that is plaguing me on this scenario I have
done and I am not sure I understand how Serialization occurs on an
interface when it is done on a per VC basis. Serialization is stating
the amount of time it takes the interface to queue the packet and send
it out I believe. So with multiple classes applied on the interface is
each queue serviced independently or are they all the same.
For example you are asked to minimize the serialization of
VOIP traffic going from Router4 to Router5 and your CIR is 768000. To
minimize this I would set my Bc = 7680 and fragment any packets going
out that are greater than 960 bytes since 7680 bits = 960 bytes. There
is a second VC that goes from Router3 to ROUTER5 but with the second VC
they don't specify that the Bc should be set to a minimum. In the
solutions guide for this question it shows the Bc being set to 48384 but
wouldn't it also need to be set to 7680 and fragment anything above 960
to meet the requirements of TASK 1 or is each queue serviced
independently and I am not understand the term serialization delay?
Please help this is bugging me that I can't answer this question to
myself?
