Datagram network provides network-layer connectionless service,
while virtual-circuit network provides network-layer connection
service. Describe the forwarding tables for each service.
1) Two key network layer functions are
forwarding and routing.
What are forwarding and routing?
How does a router work ?
2) 1. Distinguish between the process
of routing a packet from the source to the destination and the
process of forwarding a packet at each router.
2. List four types of delays in a packet-switch network.
1) The two functions of the network layer are __________ and
_____________
a) addressing, forwarding
b) addressing, routing
c) error detection, routing
d) addressing, error correction
2) When manually configuring the TCP/IP network addressing
information on a computer, which of the following pieces of
information is NOT needed?
a) The IP address of at least one DHCP server
b) The IP address of at least one DNS server
c) The subnet mask
*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
Explain "In a virtual network, service is described in a data
structure, and exists entirely in a software abstraction
layer, reproducing the service on any physical resource
running the virtualization software.
The configuration attributes of the service can be found
in software with API interfaces, thereby unlocking the
full potential of networking devices."
Jacob and Margot are meeting again to discuss Jacob’s report on
the current state of NewSky Services’ collaborative and networking
practices, and his preliminary suggestions for action. Margot:
‘Firstly, thanks for all your hard work on this report, Jacob! I’ve
taken it to our overseeing committee, who are very impressed with
your suggestions.’ Jacob: ‘Great. I think we have a lot of room to
expand our services and become more efficient through increased
networking and participation. Where would you like...
