If we have a link with 128 Kbps speed, for a particular class we shape it
to CIR=64 Kbps, Tc= 125 msec -- Bc= 64000x125/1000= 8000 bit = 1000 byte.
Given that, at the Bust period for this class:
1- What will happen to a Packet from this class with 1500 byte length ??
the Bc is only 1000 byte !!!. this packet requires more 500 bytes bits over the Bc !
2- What will happen to the third Packet of three consequent packets from
that class with 400 byte per each packet. The summation of the first two
packets is 800 bytes still can be transmitted within the Bc (1000 byte), but the third packets requires 200 bytes over the Bc !
In those cases, Packets will be queued or transmitted, or fragmented ?
Thanks in advance
