A frame containing http request is sent from Computer (A) [in whichever subnet it is now, make sure to show it in your figure], to the access point it is associated with. Draw the address fields (1, 2, and 3) of the frame travelling from Computer A to AP and the source and destination addresses of the frame travelling from AP to R1. The MAC addresses of AP1, AP2, and AP3 are M1, M2, and M3 respectively, and the Router R1’s MAC address connected to this Switch/AP is MRA. IP address values are already given, and the port addresses could also be used as given. The Router’s MAC address facing WAN side is MRW.
Discuss the invocation semantics that can be achieved when the request-reply protocol is implemented over a TCP/IP connection, which guarantees that data is delivered in the order sent, without loss or duplication. {Note: Take into account all of the conditions causing a connection to be broken}
2. The following illustration shows a transmission from Host A to Host B using Network Address Translation (NAT). Host A is located inside a Local Area Network (LAN) with an IP address of 192.168.1.2. The LAN is connected to the Wide Area Network (WAN), i.e. the Internet, through a router R1 that conducts NAT. R1 has two interfaces with an internal LAN IP address (192.168.1.1) and and external WAN IP address (127.45.10.35). Host B is located outside the LAN and is a well-known server, e.g., Google's server. Host B has an IP address of 130.160.23.45. Port numbers for the application components running at both hosts are provided in the figure. For a single message M1 being sent from Host A to Host B, please fill in the blanks in the illustration below with the source IP address and Port number at Host A and at the Router R1. Any information not provided may be assumed, however, please state your assumption clearly. Host A Local Area Network (LAN) IP: 192.168.1.2 Port: 5252 Source IP…
Problem 3 Consider the problem of deciding whether to implement a virtual- circuit or a datagram network. Assume a network protocol that allows the system to operate as either a virtual circuit network or a datagram network. That is, its packet header format is specified such that it incorporates both a VCI (Virtual Circuit Identifier) and an arbitrary source/destination addresses. When operating as a virtual circuit, it requires a 4-byte header. When operating as a datagram network, it requires a 40-byte header. Assume that there are 4 hops from source to destination, and that a set up or tear down request packet is 80 bytes (including the header). The total message length is 4096 bytes, the data rate is 9600 bps on all links and the packet size is 256 bytes (including the header). i) If we operate in the datagram mode, how long does it take for the first packet to reach the destination? If we operate in virtual-circuit mode, how long does it take for the first packet to reach the…

3. 15. 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?
