Visual Route and Virtual Network Computing Exercises for Computer Network Courses


Knowledge of networking concepts (network usage) has become crucial in today’s world where all of us use different types of networks in our day-to-day life. But in a field like networking, real understanding can be achieved only by hands-on exercises. In this article, six lab exercises on Visual Route and Virtual Network Computing software suites are discussed, and how they could be further enhanced by teaming them with firewall hardware/packet sniffers, or with firewall software such as Zone Alarm. This work can be expanded with discussions of other networking concepts and technologies that will enhance one’s networking experience.


Visual Route is an easy to use graphical user interface that integrates various tools such as traceroute, ping, and whois (the most common commands taught in a networking course) to check Internet connectivity, and displays the actual route of connections and IP address locations on a global map (Exercise 2, Exercise 3). Visual Route presents a general analysis of the specific traceroute in terms of the following: • The total number of hops encountered • The average response time of each hop • The time it takes for a DNS lookup • The TTL value of packets received • The exact place where a problem occurred • The type of Web Server running at the destination site • The general idea of throughput achieved • A graphical representation of the entire path taken to reach the destination server • A route table which displays detailed information about each hop such as the node names, their location, and the major network backbone in use at these nodes. Clicking on any node names gives the whois information associated with that node which provides an instant contact for reporting a problem. It also has the ability to track emails. Incorporating a firewall will help to solve the security issue and make Visual Route better. Because of the packet filtering provided by firewalls, it is possible for the user to allow or deny transferring data from a specific IP address. A packet sniffer or a network analyzer could be integrated with Visual Route to enhance its functionality. This analyzer would read and capture the packets that pass through a network segment (Exercise 4). By using information from the captured packets, a packet sniffer can identify erroneous packets, and can use the data to determine the bottlenecks in the network and show the overall network performance.
