re: Procket Gets Unstealthy I am really curious about this so called VLSI microprocessor. It is said that it is different from the OLD generation of network processors. Does this indicate that it is a new generation of NPU?

At least it proves that the NPU approach works :-)

The new generation of NPU will replace more and more ASICs in the core and edge routers.

____________________________________________
The company has also taken an innovative approach to developing hardware. Instead of burning the routing functionality and features into ASICs, the company has leveraged Very Large Scale Integration (VLSI) microprocessor technology to build high-speed packet processors. Unlike the older generation of network processors, VLSI microprocessors are highly integrated, allowing for packet processing speeds up to 40 Gbit/s on 40-byte packets.

re: Procket Gets Unstealthy First, congratulations. I hope I get to play with one of these boxes sometime.

For in service upgrades, what we're making available today is the ability to install a replacement module for one of IS-IS, BGP, OSPF or PIM and then restart that particular process. Today this would be typically used to phase in patches. Yes, this would cause a service interruption, but all other processes would still be alive.

Tony, so you do not offer hitless upgrade for these boxes? Is it possible to use graceful restart to do a complete hitless upgrade, or is that not possible?

About Caspian, their box sounds a lot like Vivace, with their emphasis on flows and QoS.

Highlights of Procket Network's PRO/Silicon technology include:

-- Industry's first 40Gbps network processor
-- Fully programmable network processor - enabling new feature additions
via simple software upgrades, avoiding costly hardware upgrades common
today
-- Industry's first Terabit Switch Engine used in the highest performance,
service-optimized, switch fabric available today
-- Enables systems that scale up as well as down - one chipset supports
high-performance platforms that range from 80Gbps to 960Gbps.

re: Procket Gets Unstealthy The real joke.

If you went to Caspian's site a week ago, you would have been able to pull down an 11 page PDF on the Apiero Switch. That was the first name, now we have the Apiero Router, nice try Caspian. No customers. feels rather desperate.

Great article on Procket Maggie, go get Caspian, it fraud.

re: Procket Gets Unstealthy I'm a firm believer that the routing infrastructure is in dire need of zero downtime upgrades, whether this alone is enough of a differentiator for Procket remains to be seen. I frankly hope so. In the not-too-distant future we'll be looking at the core with the same reliablity expectations as the class5 switch. We've reached that maturation point.
------------------

Based on tony's comments, it doesn't sound
like a zero-downtime upgrade. They could
do it through graceful restart, but some
people (at least in cisco's case) have found
out by now that claims don't sometimes mean
much. (i.e. if you give me graceful restart
and it comes with so many different restrictions
that I can never use it, you've wasted my
time and given me nothing.)

There are multiple companies working on what
I would consider more of a true hitless upgrade
with stateful redundancy. Of course its a
difficult problem and none of the people working
on it have proved that they can do it in anything
beyond a "toy" network.

re: Procket Gets Unstealthy A story on Caspian will be up on the site soon.

re: Procket Gets Unstealthy Then VLSI is marketing smoke since it is simply an in-house NPU.

Procket needs to search NPU conference proceedings to verify whether their VLIS is an industry's first 40Gbps NPU. I remeber that Clear Speed Inc. has a OC-768 NPU in 2002.

It looks like NPU has a bad reputaion in the networking industry. People adopted the technology but do not want to endorse its name :(

re: Procket Gets Unstealthy As far as I understand, the carriers won't qualify
hardware vendors that use Gate D or BSD, or
any other routing code that is "off-the-shelf".
This isn't some unique Procket feature, this is a
requirement set forth by the customers. Any
equipment vendor worth his weight needs to do the
same thing if they want to sell product.
-----------------

No. The real requirement is that the vendor
has stable routing code that works. And that
they have staff in-house to support their
routing code.

Carriers are going to ask where the code
came from. And how the vendor answers usually
is what determines if someone will take a chance
or not. Regardless of the source, you are going
to have to show that your code works. And
no commerical package is good enough to take
without major changes.

re: Procket Gets Unstealthy Really??? I thought barring Procket, everybody does/did it!
