Lan Topologies for Test

LAN is a very flexible architecture used for computing and with the introduction of LXI will be used for test systems. This paper will show typical LAN topologies for test systems pointing out the pros and cons of different configurations. The topology selected may have an impact on the performance of the test system. The paper wiII also delve into the need for LAN security and give practical advice on setting up test networks that protect the system from intruders. It will pay particular attention to LXI class B (using IEEE 1588) networks with practical advice on the position of instruments in the network and the use of boundary clocks for accurate timing.
