Forwarding Expand-over-ATM Packets to Other
Expand Line-Handler Processes
Forwarding Expand-over-ATM Packets to Other Expand Line-
Handler Processes
Packets received by an Expand-over-ATM line-handler process can be forwarded to
another type of Expand line-handler process, either on the same processor or on a
different processor. Packet forwarding is performed via the message system; this
allows servers without Expand-over-ATM line-handler processes to access an ATM
network. Figure 17-18 illustrates the flow of packets between two applications, one of
which is running an Expand-over-ATM line-handler process and one of which is not. In
the figure, Expand-over-ATM line-handler processes are running on nodes 1 and 2.
