The lab is physically located within CAISR and it hosts five student desks and equipment space. A scheme of the current lab topology is shown in the figure (however, this main topology is constantly shifting as we try different experiments). Computing facilities include 1 Sun Ultra 60 (running Solaris 8), 8 Compaq and Dell workstations (from 400Mhz to 2Ghz, running Linux and Windows 2000), and one HP laser printer. The workstations support several programming languages (e.g., Java, C, C++, VisualStudio.net) and software (e.g., LEDA, Cplex, ns-2, LaTeX, Words). Additionally, we can remotely access and use the Beowulf Linux cluster hosted within the Ohio Supercomputing Center. We are currently using this cluster for network simulations. The interconnectivity within the lab is provided by a Gigabit Ethernet, composed of a 3Com and a Netgear switch (includes 802.1p support) and Gigabit cards on the workstations, as well as a FastEthernet switch connecting some of the older machines. One of the FreeBSD workstations acts as a bridge and runs a wide area emulator (dummynet), which allows us to transparently introduce wide-area delays between distributed applications running on other lab machines. As for wireless connectivity, the lab has an 802.11b wireless access point connected to the switch, a Pentium laptop, an iPaq 3850 PocketPC with an expansion pack, and the two corresponding wireless 802.11b card. A firewall router acts as the gateway between the lab and the rest of the Internet. The firewall blocks certain types of packets (e.g., multicast) within the lab. Thus, we are compliant with the policies set by the campus-wide system administrators, while we can pursue flexible experimentations within the lab.
