3.2 Multiple Client Architecture
The RS8234 provides multiple independent control and status communication
paths. Each communication path, or flow, consists of a control queue and a status
queue for both segmentation and reassembly. The host assigns each of these
independent flows to system clients, or peers. As throughput requirements
escalate, the host system can add processing power in the form of additional
peers. This degree of freedom creates a scalable host environment. The RS8234
provides an ATM server for up to 32 clients.
client/server relationship.
As shown in
host can also assign control and status queues to system software tasks, or logical
clients. Since the queues offer individually distinct communication paths, each
logical client interfaces to the RS8234 independently. Due to its server
architecture, the RS8234 supplies the synchronization between asynchronous
tasks requiring ATM services.
