New Darwin Testbed Configuration

(This picture generated by Visio.)

Here is the picture of the darwin testbed in postscript format.
Here is a picture of the Remulac testbed in gif format.
Here is the picture of the Remulac testbed in ps format.

Routers in the picture are the wexford-x boxes, endpoints are ellipses. IP addresses in the endpoint ellipses denote the testbed IP address (not the cs ip address) and start with 192.168. Links that are black are 100mbps. Red links are ATM (155mbps). Green links are 10mbps.

Shown above is the part of the testbed primarily used by the people working with the Darwin project. The part of the testbed primarily used by people working on the Remulac project can be accessed via the links above. The two parts of the testbed are connected via a full-duplex 100mbps link between keywest and suez. Unfortunately, the combined testbed of 7 routers is a little too big and complex to show in one diagram.

The endpoint machines connected to the testbed have two network interfaces. One is a 10mb/sec interface that connects the machine to the CS network. The other is the 100mb/sec interface that connects it to the testbed. The 100mb/sec interface can only be reached from inside the testbed (ie. from another testbed machine). All testbed ip addresses start with 192.168, so that piece of the ip address is not listed in the table below. Here are the names (see picture to see which endpoints are currently connected):

There may be other endpoints connected in the picture that are not listed here. These belong to other groups and are not available for general use.

All the links automatically come up as 100mb after reboot, but they can be reconfigured for 10mb.

The routers in the Darwin portion of the testbed are running FreeBSD 4.3. The routers in the Remulac portion of the testbed are CISCO 7206's. FreeBSD kernel sources are in /afs/cs/project/cmcl-darwin.

To reset the FreeBSD routers (clean up classes, etc.) run /afs/cs.cmu.edu/project/cmcl-darwin/eugeneng/demo/reset. The program reset_script cleans up all de interfaces on the router.
