IP is a connectionless protocol, whereas TCP is connection-oriented. How can these two protocols live in the same stack the best manner possible?
A router interconnects a subnet, where all the interfaces of the subnets must have the prefix 164.132.62/24. suppose that the Subnet is required to support up to 60 interfaces, provide a network address that satisfies the above.
Consider the datagrams of each layer in the TCP/IP model, e.g., Frame at the Link Layer, Packet at the Internet Layer. Explain the functioning of the following protocols based on their datagram header fields only. Note: You do not need to describe the header field but based on the header field, explain how the protocol works, e.g., Acknowledgement field in a TCP Header is responsible for providing reliable data transfer and in case of data loss or ACK not received, segment is re-sent. You do not need to consider every field of the headers but wherever there are more than 4 fields, then based on 5 fields, describe its functioning, if less than or equal to 4 fields then consider all the fields.

The UDP protocol is a messaging protocol. Token-based protocols like TCP are known as byte-oriented protocols. Which protocol, UDP or TCP, should an application employ to safeguard the message's boundaries?
SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. You have defined the packet filter rule set shown in the table below. These rules permit and/or deny inbound and outbound traffic between the user agent and the mail server. Describe the purpose of each packet filter rule in the table. Rule Direction Source Address Destination Address Protocol Destination Port Action A2 In External Internal TCP 25 Permit B2 Out Internal External TCP > 1023 Permit C2 Out Internal External TCP 25 Permit D2 In External Internal TCP > 1023 Permit E2 Either Any Any Any Any Deny
Host A and B are directly connected with a 100 Mbps link. There is one TCP connection between the two hosts, and Host A is sending to Host B an enormous file over this connection. Host A can send its application data into its TCP socket at a rate as high as 120 Mbps but Host B can read out of its TCP receive buffer at a maximum rate of 50 Mbps. Describe the effect of TCP flow control.
QUESTION 13 Fill the blank With the TCP server, there is a welcoming socket, and each time a client initiates a connection to the server, a new socket is created. Thus, to support n simultaneous connections, the server would need sockets. O n-1 On O n+1 01
TCP is a connection-oriented protocol. This means that... O a. both of the endpoints communicating over TCP keep information about the state of the connection. O b. a TCP sender can start sending data to the receiver before the three-way handshake takes place. O c. there is a direct physical connection between the two endpoints of a TCP session. O d. both endpoints of a TCP session have to connect to a third party before data can be sent or received.
A protocol stack used by many applications is to use TCP at the transport layer and IP at the network layer. The ICMP protocol is also used to report on problems encountered by IP. A) The IP protocol provides a service referred to as "best effort". Describe the services of IP and potentially ICMP protocol, with respect to flow control( ensuring the sender does not overwhelm the receiver). B) Describe the services TCP provides with respect to flow control and explain the mechanisms it uses to overcome the deficiencies of IP.
Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes
List the three auxiliary protocols at the network layer of the TCP/IP suite that are designed to help the IPv4 protocol. When an IP datagram is travelling between networks, can the value of the TTL field in the IP datagram be any of the following? Explain your answer. 23 0 1 301 Which field(s) in the datagram are responsible for gluing together all fragments belonging to the original datagram?
