Computer Networks: A Systems Approach is a comprehensive exploration of modern network design, emphasizing a systems perspective that integrates established technologies like TCP/IP, microservices, and distributed computing. The book begins by laying a solid foundation with discussions on modular design, scalability, and the essential mechanics of direct link networks, including encoding, framing, and error detection. It then delves into advanced concepts such as packet switching and internetworking, which collectively ensure efficient, reliable, and dynamic data transmission across diverse systems. Finally, with chapters on end-to-end protocols, congestion control, data transformation, and network security, the book highlights the interplay between robust engineering practices and real-world applications, offering readers a thorough understanding of the challenges and solutions in modern digital communication.

Problem 1
Use anonymous FTP to connect to ftp.isi.edu (directory in-notes), and retrieve the RFC index. Also retrieve the protocol specifications for TCP, IP, and UDP.

Problem 2
A sender on a TCP connection that receives a 0 advertised window periodically probes the receiver to discover when the window becomes nonzero. Why would the receiver need an extra timer if it were responsible for reporting that its advertised window had become nonzero (i.e., if the sender did not probe)?

Problem 3
An organization has a class C network $200.1 .1$ and wants to form subnets for four departments, with hosts as follows: A 72 hosts B 35 hosts C 20 hosts D 18 hosts There are 145 hosts in all. (a) Give a possible arrangement of subnet masks to make this possible. (b) Suggest what the organization might do if department D grows to 34 hosts.
Problem 4
Suppose the round-trip propagation delay for Ethernet is $46.4 \mu \mathrm{s}$. This yields a minimum packet size of 512 bits ( 464 bits corresponding to propagation delay $+$ 48 bits of jam signal). (a) What happens to the minimum packet size if the delay time is held constant, and the signalling rate rises to $100 \mathrm{Mbps}$ ? (b) What are the drawbacks to so large a minimum packet size? (c) If compatibility were not an issue, how might the specifications be written so as to permit a smaller minimum packet size?
