IXP1200 Network Processor Family ATM
Figure 4 shows how data stream PDUs can be created in the Workbench for ATM, Ethernet, IP, and other protocol data streams. These data streams can then be assigned to feed different ports. To test how the example design performs IP routing, different destination IP addresses can be chosen in the PDU.
Figure 4. Developer’s Workbench - ATM Data Stream Dialog Box
Figure 5 shows the IX Bus Device Status window. This window gives a continually updated snapshot of IX Bus activity. It can be used to gain an overall picture of what data is being transferred over the IX Bus "on-the-fly", and the data or wire transmission rate. The Data Streaming feature and the IX Bus Device Status window are both documented in the IXP1200 Development Tools User’s Guide.
In the simulation environment, the IP and ATM VC table management software that normally run on the StrongARM core are emulated with a combination of Transactor (simulator) foreign models and interpreted Transactor scripts.
