The alternatives that immediately come to Mind are: - Xilinx Virtex II Pro with Linux (Linux port posted 2 months ago and on ftp.mind.be) - Intel IXP425 with Linux (Linux port expected Jan 2003) I believe both those chips where targeted specifically to build high-end, modern one-chip routing solutions. They have high speed connections on them. What is the bandwidth and number of interfaces you are targeting ? > In this process, we need to freeze the target CPU.

XScale (ARM derived) is also a new performant platform that is available at high frequencies in certain chips (80200 e.g.). Typical operation frequencies of PowerPC405 and XScale in both chips are 300 MHz I believe. Please note that the use of the FPGA created some very spectacular possibities, such as the idea to build-in a wirespeed firewall in the FPGA logic, where you could reprogram the rules through a reconfiguration of the FPGA filters (this is not a SW firewall, but it is still reprogrammable).
