Firewall load balacing switches

["sami seclist" <sg.seclists () gmail com>]

Hello list,

I'm looking for a solution that can balance the network load on two
different firewalls.

It appears that cisco 6500 switch with csm module can do this but it's
pretty expensive.
Do you know of other manufacturers that can provide load balancing
switches and that can support 500000 concurrent sessions ?

thanks
