Site LAN Considerations

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.
For applications requiring access by many users or by users at
distributed sites, a site LAN network is required. In addition to
supporting multiple users, site LANs often offer the advantage of being
maintained by IT departments. When using a site LAN, consult your IT
department regarding LAN configuration and security issues.
