A private network generally involves a direct connection between the
computer and the instrument, or to multiple instruments using switches
or routers. Access to the instrument is limited to users on the private
network, as opposed to users on a site network that could locate and
access the instrument from any location.
Private networks can reduce the possibility of tests being disrupted by
unplanned or unauthorized access. Code generation for test systems on
a private network is often simplified, as provisions against
unauthorized users may not be required.
Test systems where large amounts of data are transferred usually have
faster throughput on a private network. On a site network, heavy and
unpredictable LAN traffic affects each instrument (node) on the
network. The impact on a test system is that repeatability is difficult to
achieve as latencies are difficult to account for.
Private networks are fundamentally more reliable than site networks
as they host fewer users and are less complex than site networks.
Private networks are isolated from conditions that could bring down
(crash) a site network.
Every instrument (node) on a LAN (private or site) has an IP (Internet
Protocol) address. Due to the expanding use of the internet, the number
of site network IP addresses available is limited. By using a router with
Dynamic Host Configuration Protocol (DHCP) capability on a private
network, the router can assign an IP address to each instrument thus
creating a sub-network (subnet) that does not consume site IP
addresses.
