Introduction An introduction to the software and organization of the Internet Lab.

Virtual Lab Equipment GNS3 network simulation software is used to create network topologies. The software uses virtual Ethernet hubs and switches and Cisco 2611 routers Routers are labeled: Router1, Router2, Router3, Router4….. Routers run Cisco IOS 12.0 version. Hubs and Ethernet switches are all embedded in GNS3. The labs also use Wireshark Traffic Capture and Analyzer software (and for Macs X11 is also required) The labs use VirtualBox and Virtual PCs to simulate hosts. PCs are labeled as: PC1, PC2, PC3, PC4…..

Labs Lab 1 – Introduction to the Internet Lab Overview of the Internet Lab Software. Lab 2 – Single Segment IP Networks Configuring a network interface for IP networking; address resolution with ARP; security problems of common Internet applications. Traffic capture Lab 3 – Static routing IP forwarding and routing between IP networks; setup a Linux PC and a Cisco router as an IP router; manual configuration of routing tables. Lab 4 – Dynamic Routing Protocols Routing protocols RIP, OSPF and BGP; count-to-infinity problem in RIP; hierarchical routing in OSPF; setup of autonomous systems in BGP. Lab 5 – Transport Protocols: UDP and TCP Data transmissions with TCP and UDP; TCP connection management; TCP flow control; retransmissions in TCP; TCP congestion control.

Labs Lab 6 – LAN switching LAN switching in Ethernet networks; forwarding of Ethernet frames between LAN switches/bridges; spanning tree protocol for loop free routing between interconnected LANs. Lab 7 - NAT and DHCP Setup of a private network; dynamic assignment of IP addresses with DHCP. Lab 8 – Domain Name System Domain name resolution with DNS; name server hierarchy; setup of a DNS root server.

Structure of the Labs Each lab has two phases: a lab exercise, and a lab analysis. Lab Exercises Students follow the steps for each lab exercise that are performed on the GNS3 software. All lab exercises can be completed without supervision. The time to complete a lab session should be three hours on average, but may vary. Complete the laboratory activities to the extent that you can. The activities during the lab session are not graded. Lab Analysis At the end of most lab exercises are a series of questions. It is recommended that you answer the questions using the data you collected whilst running the exercises. The lab quizzes will be based on the information you have learnt in your lab sessions including the exercises and corresponding analysis. The quizzes will be very similar in structure to the exercises you are required to do for each Lab.
