The AI-SRVR-1 and the AI-SRVR-8 can be used together

— for example, to add a

remote ARCNET node to an eight-node ARCNET system as shown in Figure 10.

The AI-PROXY concept requires each local proxy represent a node in the remote
network by assuming the Node ID of the remote device being represented. The local
proxy also has a Connections table for these two parameters of each remote proxy:

Node ID being represented by the remote proxy

IP Address of the remote proxy

Thus, each Connections table entry associates the local Source ID with the IP Address
through which it is represented in the remote network.

Because a proxy could communicate with many other proxies (up to 255), its
Connections table could be large. No matter how many proxies are involved, each
local proxy must invariably represent a remote node whose ID is not present in the
local network
where the local proxy resides.
