Next, a column that describes thefunction of the layer. Then a column that lists the Protocol Data Units (such as Datagrams, Frames, etc) that correspondto each layer in the OSI model. Continue this process for the major hardware or software applications that function ineach layer (not all layers have corresponding applications).The last column should be the TCP/IP model aligned to the appropriate layers of the OSI seven-layer model. This shouldresult in a document that looks something like the chart tab (with the blank spaces filled in!)

Provide an example of a protocol at each of the TCP/IP model layers, for example that you have used in the above. Also give an example of overhead added in each of these protocols, e.g. a field in the protocol header. If possible, provide information on the maximum size of each packet, and the size of the header, of each of these example protocols.
TCP / IP uses the client-server communication model, in which a user or computer (a client) receives a service (such as sending a web page) from another computer (a server) on the network. In short, the TCP / IP protocol suite is classified as stateless, which means that each client request is considered new because it has nothing to do with previous requests. Being stateless, network routes are released so that they can be used continuously. Answer the following questions briefly. How does resource reservation work in the TCP / IP model? Which TCP / IP layer is responsible to reserve resources across a network using the TCP / IP model? What protocol assigns an IP address to the client connected to the Internet? Checksum is used by various protocols on the Internet, but not at the one of TCP / IP Explain.
In transport layer protocols, acknowledgements are one of the techniques available (such as the RDT 2.0 protocol that we covered before). Is it possible for an acknowledgement to be contaminated in some way? So, what is the process in place to deal with this situation?
While developing a reliable transport protocol, early versions of the protocol discussed in class used a NAK message, sent by the receiver to the sender to indicate a packet was not correctly received. This kind of message, however, is not found in further protocols, like GBN, SR or even TCP. Why not? In other words, why don't these protocols provide a way to signal to the sender that the received message was received with an error
Here, we'll contrast "connectionless" and "connection-based" protocols to see what makes them unique.
Can the process of a protocol's transition between OSI layers be described?
Please give a short outline of the pros and cons of connectionless protocols as a possible solution for connection-based protocols.
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.
Provide a succinct outline of the pros and cons of using connectionless protocols as an alternative to connection-based protocols as an alternative to connection-based protocols.
For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.
Layered protocols have two most convincing reasons why they should be implemented. What you're stating has to be backed up by an example.
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.
