What is the Transport Layer and what does it do?
(Please explain flow control, error management, and segmentation
and reassembly in the Transport Layer)
what is transport layer? what are the typical attacks in
transport layer? what are the controls that are employed in the
layer to minimize the attack or vulnerability that leads to the
attack? cite references
*2- Describe the role of the communication layer, the
network-wide state-management layer, and the network-control
application layer in the SDN controller.
*3- Name the four different types of ICMP messages including
type and code. What two types of ICMP messages are received at the
sending host executing the Traceroute program?
*4- Why are different inter-AS and intra-AS protocols used in
the internet? Explain your answer.
A. The 802.11 LLC unacknowledged connectionless service provides
no flow control or error control.
TRUE or FALSE
B. An 802.11 extended service set (ESS) consists of two or more
BSS’ interconnected by a distribution system (DS).
TRUE or FALSE
C. The 802.11 "integration service" performs address translation
during a logical connection between the WLAN and external 802.x
LANs.
TRUE or FALSE
a. Critically analyse the role of flow and error control in a
computer network. In your explanation appropriate figures and
examples are expected.
b. Calculate the CRC for the X binary data shown as shown below,
when the divisor is 1101.
(A)2 = (200 + X)10 X = 1001100
c. Consider a scenario where a frame would be sent after
appending the checksum to the original data. How would you prove
that the frame received is error free?
b) UDP does not
provide end to end flow control, but TCP does. Explain how this is
achieved using sequence numbers. Give an example where a packetized
message sent using UDP is received incorrectly, but when using TCP
it is received correctly under same circumstances without channel
errors.
In the context of management control, what is the issue of
myopia and how does it arise? How might one attempt to resolve this
myopia problem?
