The service model of a network layer "defines the characteristics of end-to-end
transit of packets between sending and receiving hosts," according to us. What is
the network layer of the Internet's service model? What guarantees does the
Internet's service model make about datagram delivery from host to host?
Consider the figure below. The IP and MAC addresses are shown for nodes A, B, C and D, as well as for the router's interfaces.
Consider an IP datagram being sent from node D to node A. Give the source and destination Ethernet addresses, as well as the source and destination addresses of the IP datagram encapsulated within the Ethernet frame at points (5), (4), (2), and (1) in the figure above.
1.
Datagram subnets route each packet as a separate unit, independent of all others.
Virtual-circuit subnets do not have to do this, since each data packet follows a
predetermined route. Does this observation mean that virtual-circuit subnets do not
need the capability to route isolated packets from an arbitrary source to an arbitrary
destination? Explain your answer.

- One approach that might be used in a mobile network architecture that would allow a datagram sent by the correspondent to reach a destination mobile device is to allow mobile users to maintain their IP addresses as they moved among foreign networks. The foreign network would advertise a highly specific route to the mobile user and use the existing routing infrastructure to propagate this information throughout the network. Scalability is a concern in this approach. Suppose as the mobile user moves from one network to another, the old foreign network withdraws its route as the new foreign network advertises the specific route to the mobile user. Take into consideration how routing information propagates in a distance-vector algorithm or inter-AS routing protocols like BGP. Also think about interdomain routing among networks that span the globe. Are datagrams routed immediately to the new foreign network as soon as the foreign network begins advertising its route?

- An entry in the switching table of a virtual-circuit network is normally created during the setup phase and deleted during the teardown phase. In other words, the entries in this type of network reflect the current connections, the activity in the network. In contrast, the entries in a routing table of a datagram network do not depend on the current connections; they show the configuration of the network and how any packet should be routed to a final destination. The entries may remain the same even if there is no activity in the network. The routing tables, however, are updated if there are changes in the network. Can you explain the reason for these two different characteristics? Can we say that a virtual-circuit is a connection oriented network and a datagram network is a connectionless network because of the above characteristics?arrow_forwardTell me about the distinction between Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).

(ii) Identify the byte order used to represent these addresses within the segment header. (iii) If a port number contained in the segment header is passed to the Application layer, identify the function used to convert it to the correct byte order within the application.arrow_forwardConsider each layer of the TCP/IP protocol stack and order them from most important to least. Can one or more of these layers be combined or separated? Would the kind of information being sent affect how you order, and if so, why or why not? Why did you decide to place your order that way? To assist you, use the following scale: The most important component is represented by 1, while the least important factor is represented by 5.arrow_forward
