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}
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…

6.7-1. To which protocol do these fields belong? We learned way back in Chapter 1 that "a protocol defines the format and the order of messages exchanged between two or more communicating entities ..." and throughout the course, we saw many, many different messages being used throughout the protocol stack, each with different fields. In this question, for a given field name in a protocol message (i.e., in an application-layer message, transport-layer segment, network-layer datagram, or link-layer frame), use the pulldown menu to match the field name with the protocol (or pair of protocols) where this field name is used. Each protocol name (or pair of protocol names) in the pull-down menu should be matched to exactly one field description.
