Hi,

I am considering some bandwidth management solutions and would like to
know if some of you people have had some real world experiences with
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.

In the past days I've been analyzing solutions from Allot and P-Cube,
and some of them would seem to be fine, but I would like to know if you
have had experiences with these or other products that might fit for the
job. I would greatly appreciate all the advices, recommendations or
suggestions that you may want to share about this.

Thanks in advance.

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).
