IXP1200 Network Processor Family ATM OC-3/12/Ethernet IP Router Example Design
12 Application Note
Modified on: 3/20/02,
Figure 4 shows how data stream PDUs can be created in the W o rkbench 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 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.
