- Most IP datagram reassembly algorithms have a timer to avoid having a lost fragment tie up reassembly buffers forever. Suppose that a datagram is fragmented into four fragments. The first three fragments arrive, but the last one is delayed. Eventually, the timer goes off and the three fragments in the receiver's memory are discarded. A little later, the last fragment stumbles in. What should be done with it?In TCP/IP communication, a session needs to be established before communication and terminated after the communication. With the aid of diagrams critically explain TCP session establishment and termination processes in communicationTunneling procedure? Which three tunneling protocols exist?
- Explain the significance of "handshaking" protocols at the "Session Layer".It is important to keep in mind how a sequence of packets are sent from one host to another along an established route. Please give a list of the delay components that make up the total end-to-end delay of a single packet. To what extent are any or all of the delays predetermined?It is possible for a series of packets to be sent from one host to another over the same route. Please break down the time it takes for a single package to go from beginning to conclusion. Is it expected that one of the delays would last a certain period of time and the other delay's length will be more variable?
- Think about sending an email or other kind of message over the same route from one host to another at a certain time frame. Below you'll find a breakdown of the delay's many components. Is one of these lags a constant or does it change over time?Design a key establishment protocol that will allow a Mutually Agreed Session key (Kabc) to be established between three entities A, B and C. This key can then be used to secure a chat between the three entities. I want you to develop your own design based on the conditions below. Note: The session key should NOT be known to the Chat Server (S) and the Chat Server (S) can only forward the encrypted messages to A, B and C and S cannot read the messages,i.e. End to end encryption/privacy is to be used between the chat parties A, B and C. The secure chat between entities A, B and C must use the Chat Server (S) and session key Kabc as below: i.e. A, B and C Do NOT communicate directly and must exchange messages through the Server S. The following conditions apply to your protocol design. 1. A, B and C Never communicate directly. Each entity (A, B, C and S) have a Public Key Certificate, ie. CA<<A>>, CA<<B>>, CA<<C>> and CA<<S>>.…It is theoretically feasible for two hosts to communicate with one another by sending packets back and forth over the same connection. Please enumerate all of the components that are responsible for the overall amount of time required to process a single packet, starting to end. Is it to be anticipated that one of the delays will continue for a certain amount of time, while the duration of the other delay will be more unpredictable?
- Let's imagine, for the sake of illustration, that a packet is now being sent from one site to another along a predetermined route. The following is a list of the components that make up the delay: Which of these delays is an ongoing problem, and which of them is sporadic in nature?The tunneling process entails what steps, exactly? Can you name the three protocols used for tunneling?Design a security protocol that will allow a Mutually Agreed Session key (Kabc) to be established between three entities A, B and C. This key can then be used to secure a chat between the three entities. I want you to develop your own design based on the conditions below. Note: The session key should NOT be known to the Chat Server (S) and the Chat Server (S) can only forward the encrypted messages to A, B and C and S cannot read the messages. The secure chat between entities A, B and C must use the Chat Server (S) and session key Kabc as below: i.e. A, B and C Do NOT communicate directly. The following conditions apply to your protocol design. 1. A, B and C Never communicate directly. 2. Each entity (A, B, C and S) have a Public Key Certificate, ie. CA<>, CA<>, CA<> and CA<>. 3. The Chat Server, S, has access to all Entity Certificates that use its service and can provide these Certificate to its service users if requested to do so. 4. Challenge – Response…
