4.3 AI-PROXY Function
The AI-SRVR offers a function called
“AI-PROXY”. This function allows an ARCNET
node in one LAN to communicate with an ARCNET node in another LAN through an
Ethernet backbone link that can be either wired or wireless. A communication path
between two ARCNET networks requires two AI-SRVR units, each serving in one
ARCNET LAN as a proxy for a remote node in the other LAN.
Each AI-SRVR-1 can act as proxy for only one node as shown in Figure 8 . In the LAN
on the left, the AI-SRVR-1 will be present as Node ID 2. On the right, the AI-SRVR-1
will represent a Node ID value of 1.
Figure 8 — Each AI-SRVR-1 Can Represent One Node
Each AI-SRVR-8 contains eight ARCNET controllers. Therefore, an AI-SRVR-8 can
represent up to eight nodes as shown in Figure 9. The LAN on the left has sixteen
nodes including nodes 9
–16 contained (by proxy) within the AI-SRVR-8. The LAN on
the right also has sixteen nodes — eight individual pieces of equipment and nodes 1–8
represented by the AI-SRVR-8. Multiple AI-SRVR-8 devices can be used when more
than eight ARCNET nodes in an ARCNET LAN need representation.
