 also available for the development of systems based on Agere's network-processing solution. We conclude the discussion of Agere's network-processor technology by referring you to Chapter 14, "Switch Fabrics," where we cover switch fabric technologies and where Agere's 40 Gbps switch fabric chipset is covered in more detail as a leading-vendor technology case study. 2.

AGERE PAYLOADPLUS FAMILY OF NETWORK PROCESSORS AGERE PAYLOAD PLUSTM FAMILY OF NETWORK PROCESSORS SUMMARY In this chapter, we reviewed Agere's network-processor family known as PayloadPlus as well as the company's latest 10 Gbps chipset and the most recently announced APP550 network processor, which is a highly integrated OC-48 realm solution and the latest entry into the family. We discussed the unusual partition of packet processing and switching tasks that the original Agere approach dictated and identified its interesting characteristics. We reviewed the programming model for the Agere NPU platform, which is based mainly on the company's FPL programming language. FPL allows tremen- dously shorter and efficient code writing compared to traditional C language coding, thereby mini- mizing development time. We will expand on these issues in Chapter 16 where we review systems considerations and trade-offs. Agere's 40 Gbps switch fabric chipset is discussed in Chapter 14 as a case study.
