t, protocol services, memory management, GxH (with X as a wild character here) frame handler formatting, traffic-engineering (TE) management, physical transport services, exceptions, and SO After simulations, code can be executed and debugged on physical hardware by using IBM's Reference Platform. This is a 5U rack-mountable chassis with integrated power, cooling, and back- plane assemblies. It contains a Packet Routing Switch Fabric blade (target) option. Up to four blades can be stacked with external DASL cabling. A PCI card implements a CP processor with a PowerPC 750. An optional 4GS3 carrier card provides an NP4GS3 with its own embedded PowerPC 405. It offers 22 sockets with the choice of a 2-port GBIC Gigabit card, a 20-port 10/100 TX card, or a 1- port OC-48c POS card. Performance It is important to mention that the IBM PowerNP NP4GS3 was the first network processor to pass all the required tests in the OC-48c configuration for the new LinleyBench 2002 benchmark. 1 In addi- tion, the NP4GS3 was the first chip in the industry objectively verified to operate at 10 Gbps while running the new IPv4 forwarding industry standard benchmark2 established by the Network Processing Forum (NPF) and certified by The Tolly Group. 1. The details about this benchmark can be found at the Linley Group's web site at http://www.linleygroup.com/benchmark/ linleybench.html. 2. More specifically, regarding the OC-48c configuration of the LinleyBench 2002, the NP4GS3 passed all required IPv4, DiffServ-with-30K-routes and DiffServ-with-100K-routes tests. The NP4GS3 passed all the IPv4 forwarding tests by forwarding all the frames at all the frame sizes with zero frame loss in an environment that included the generation of Internet-like traffic, which was sent to the NP4GS3-based system and then successfully routed the entire data stream to its next destination without errors.
