We recently conducted a bake-off between several traffic shaping vendors
in hopes of upgrading from our current PacketShaper solution.
Unfortunately, for Packeteer, they have not been as responsive to new
feature requests as much as we would have liked. Nor have they been able
to address traffic shaping in a multi-gigabit environment. The recent
BlueCoat acquisition tells me that the PacketShaper product development
has already pretty much peaked.
So if you are happy with what you like *currently* about how the
PacketShaper works, then that would be a good choice (Don't know about
NetEq). But I would not expect a whole lot of future improvements in the
traffic shaping technology from BlueCoat (I hope I am wrong -- we still
use several PacketShapers).
The "fine tuning" with the PacketShaper has only been an issue for us
whenever students find some new application (particularly games!) and
Packeteer does not have a corresponding classification.
We also looked at Cisco's Service Control Engine (really complex to
implement -- but probably works well in an all-Cisco shop), Procera's
PacketLogic (very impressive, a suitable PacketShaper replacement for us),
and Anagran's FlowRouter (the cheapest of the bunch, but no Deep Packet
