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 the telecom sector PowerPC is the standard (the optimized power consumption
of the ARM family is less relevant in switches; and PowerPC is high-performant).
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).
