Re: OT - Dynamic Routing on a Firewall?

The quantumflow processors in the new asr are cabilble of doing firewall functions (and a lot more) in hardware. The ASR will fuction as a firewall with 4.5gbps of throughput. This chip reminds me of the early days of IBM and the power pc chip. It was basically a mainframe on a chip. It started in the pc and AS400 lines and eventually expanded to run everything.

This chip will probably do the same in cisco. It will be the basis of the switch processor engine from the ISR all the way up to the CSR.

Kinda hard to virtualize an ASIC-driven operation....

AFAIK, no. Not for the Netscreen firewalls.

Cisco made ASA for pure firewalling,IPS and content security technologies
with Multiple vulnerabilities. : )

Can We do Virtualization for Juniper`s Firewall ? : ) ;)

Thanks
