A packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1,500 bytes and the link rate is 2 Mbps. What is the queuing delay for the packet? More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?
Question 7
Consider the Go-back-N protocol with a sequence number
space {0,1,2,3} and a window size N=3, and suppose that
the sender wants to send 7 packets in total (excluding
retransmissions), where the first packet sent will get
sequence number 0.
Assume that the 2-nd packet sent by the sender as well as
the first ACK with a sequence number of 2 are both lost. All
other messages arrive within 1 unit of time, and the sender
uses a timeout value of 4 time units before initiating a
retransmission. You can assume that the sender sends all
packets as soon as possible and we neglect the
transmission delay.
• List all sequence numbers in the exact order in which
they arrive at the receiver. (Note that this includes
sequence numbers of packets sent in retransmission.)
• What are the values of the send_base and
the rcv_base variables after the sender has received the
ack for its final packet?
Let's imagine, for the sake of illustration, that a packet is now
being sent from one site to another along a predetermined route.
The following is a list of the components that make up the delay:
Which of these delays is an ongoing problem, and which of them
is sporadic in nature?
