Abstract :
Network topology is an important choice for the test system designer. There are several to choose from and each has its benefits. A comparison of topologies is made based on the benefits and drawbacks for various usage situations. Some of the topologies of interest are: placing the instrumentation and the controller on the corporate intranet; using switching hubs for traffic isolation; using a second LAN connection in the test system controller as a private network for the instrumentation; placing a router between the intranet and the test system controller; widely distributing test assets. Test asset visibility to the rest of the network has both security and test integrity implications. Trading off the benefits of ready access and observation (which promotes collaboration) against system visibility needs to be carefully examined. Several use cases are presented for examination: simply connected user; semi automated test; fully automated test; remote collaboration for system problem solving.
