Exercises: Thought Questions 2-1, 2-2, and 2-3.

2-1. How do you think TCP would handle the problem if an acknowledgment were lost, so that the sender retransmitted the unacknowledged TCP segment, therefore causing the receiving transport process to receive the same segment twice?

2-2. a) Compute the minimum number of TCP segments required to open a connection, send an HTTP request and response message, and close the connection. Justify this number by creating a table showing each message and its sequence number. b) Repeat the question, this time if the HTTP response message is damaged during transmission.

2-3. Compute the minimum number of TCP segments required to open a connection, send an HTTP request and response message, and close the connection if the HTTP response message must be fragmented across ten packets. Justify this number by creating a table showing each message and its sequence number.

Paper For Above instruction

The following paper addresses the outlined questions through a comprehensive analysis rooted in fundamental principles of computer science, networking, and data communication protocols. The initial section offers definitions and explanations related to integers and binary conversions, followed by a detailed discussion of TCP (Transmission Control Protocol) behavior with respect to acknowledgment loss, as well as calculations pertaining to TCP segment counts during HTTP communication, including cases of message damage and fragmentation. The aim is to demonstrate an understanding of digital data representations, network protocols, and their operational mechanisms, with references to standard texts and current scholarly research.

Understanding integers and binary conversions

An integer is a whole number that can be positive, negative, or zero, without fractional or decimal components. Integers are fundamental in digital systems and computer programming, serving as basic units for counting, indexing, and error detection, among other functions (Kane & Engelhardt, 2021). When asked whether specific numbers are integers—for example, 4,307 or 45.7—the answer hinges on their composition. Since 4,307 contains no fractional or decimal part, it is an integer. Conversely, 45.7 has a fractional component, so it is not an integer.

Binary conversion involves translating decimal numbers into base-2 numeral systems, which computers use internally. For example, converting decimal 6 to binary involves successive division by 2, recording remainders: 6 divided by 2 is 3 with a remainder of 0; 3 divided by 2 is 1 with a remainder of 1; 1 divided by 2 is 0 with a remainder of 1. Reading remainders from bottom to top yields binary 110 (Peterson, 2012). Similarly, converting other decimal numbers—such as 15, 62, 128, and 255—follows this process, with tools like Excel simplifying the process for larger numbers.

Binary to decimal conversions and the significance of bits

Binary numbers can be converted to decimal by summing powers of 2 for each '1' in the binary digit, starting from the rightmost bit (least significant bit). For example, binary 100 (which is 4 in decimal) has a '1' in the 2^2 position; adding this up gives 4. Binary 1111 translates to decimal 15, while 10110 converts to decimal 22, and 100100 to 36. These conversions are pivotal in digital communications and data encoding.

Network protocol behavior and TCP acknowledgment handling

The Transmission Control Protocol (TCP) employs acknowledgment mechanisms to ensure reliable data transfer. When an acknowledgment (ACK) is lost, TCP's retransmission timer triggers the sender to resend the unacknowledged segment (Stevens, 2011). If the retransmission results in the recipient receiving the same segment twice, TCP's sequence numbering and acknowledgment processes are designed to handle this gracefully. The receiver discards duplicate segments if they have already been processed, thus maintaining data integrity. This process ensures robustness against acknowledgment losses, preventing data corruption or inconsistency in communication.

Calculating the number of TCP segments for HTTP transactions

The minimum number of TCP segments required to establish a connection, transmit data, and terminate depends on the TCP three-way handshake, data packets, and connection teardown procedures. For a typical HTTP request-response cycle with no damage, four segments are needed: SYN, SYN-ACK, ACK (for connection establishment), the data packet containing the HTTP request, the server's response, and finally, TCP connection termination segments (Kurose & Ross, 2017). When the HTTP response is damaged, an additional retransmission occurs, increasing the segment count. If the response is fragmented across multiple packets—as in the case with ten packets—the total count must include all individual data segments plus connection management segments.

Table 1: Minimum TCP segments for standard HTTP cycle

When the response is damaged, retransmission of segment 5 occurs, increasing total segments to 7. If the response is fragmented into ten packets, each fragment counts as an individual segment, thus requiring at least ten data segments plus initial handshake and teardown, totaling approximately 13-14 segments.

Conclusion

Understanding how data representations translate into digital communication protocols is crucial for comprehending network reliability and efficiency. Binary conversions underpin data encoding, while TCP's acknowledgment and retransmission mechanisms ensure reliable transfer despite network impairments. Accurate calculation of segment counts enhances comprehension of network traffic flow, particularly in HTTP transactions involving multiple segments or fragmentation. This knowledge forms the backbone of effective network design and troubleshooting, supported by current academic research and standards from the Internet Engineering Task Force (IETF).
