This document explores the challenges of implementing peer-to-peer (P2P) networks in campus-sized environments. It highlights the limitations of P2P networks in terms of access, performance, and security, particularly as the number of computers in the network increases. The document also emphasizes the need for a clear distinction between client-server and server-based networking in campus settings, where centralized administration and controlled user access are crucial. The document further delves into the structure of data link frames in TCP/IP connections, providing a detailed breakdown of the frame components, including the preamble, start of frame delimiter, and destination MAC address. Finally, the document demonstrates how to determine the size of a ping request frame using Wireshark, analyzing the contributions of the Ethernet header, IP header, ICMP header, and ICMP payload to the overall frame size.
