CCN Activity Session for Section 6.1 – Protecting Wireless Data Today’s activities are on the topic of protecting wireless data exchanges. Activity A simple keyword-based cipher uses the phrase “computer networking” as its key, and finishes alphabetically. Assume you have received the ciphertext VNHUIUJJ, what is the associated plaintext message? To answer, first construct the

CCN Activity Session for Section 4-1 – MANETs Today’s activities are on the topic of Mobile Ad-hoc Networks (MANETs). Discussion Why do reactive routing protocols have greater advantages in ad-hoc networks than in other classes of network? What properties of reactive protocols make them more suited to this environment? Proactive routing protocols periodically distribute routing

Digital Design Synchronous and Asynchronous Finite State Machine Implementation Pre-Assignment Preparation Why? So that students can implement a sophisticated synchronous and asynchronous finite state machines on a programmable logic device. In addition, students will teach themselves yet another language, this time a hardware definition language called Verilog. Finally, it will become apparent that the simplistic

LM CCN Section 2.1: Link State and Distance Vector Routing Computer and Communication Networks Link State and Distance Vector Routing John Easton 1 Learning Objectives ! Understand the basics of (interior) routing – How do we identify possible routes? – How do we determine cost? – How do we deal with failures? 2 What is
CCN Activity Session for Section 2.1 (Including Solutions) – Routing Within an Autonomous System As you’ve heard in the lectures, connectionless packet switched networks must be able to pass datagrams from the source to the destination host by a series of hops between network elements such as switches. Local networks are often structurally volatile, so
