AFAIK, Allot boxes do have an option to decide whether or not to drop
traffic above a certain definable number of connections, which is not
really an attack recognition but its as close as it gets in their box.
Anyway, as you say, they don't react automatically, you need to set it
first :(

this kind of boxes. More specifically I am looking at some 
Large-ISP 
or Carrier-Grade solutions with at least the following 
specifications:

= 1Gbps traffic capacity
500k simultaneous connections
Layer 7 stateful packet inspection (via protocol signatures and/or 
protocol analysis) Traffic prioritization, shaping, QoS and 
bandwidth 
provisioning based on custom defined policies (vlan id, ip ranges, 
tos, time of day, etc) possibility to easily update and 
deploy new or 
modified protocol definitions without affecting availability.

Add here: "automatic rate-limiter adaptation" / "attack 
pattern recognition".

Do we still have solutions on the table?  I'd be interested 
what kind of solutions are available in Gbit/s-grade which do 
not need you to configure certain kind of rate-limiters a 
priori, but can automatically react to most kinds of attacks, 
even simple ones (e.g., TCP SYN floods).
