Juniper Updates Core Routers

Juniper Networks Inc. (NYSE: JNPR) is announcing its latest core router today, the T4000. It's an upgrade from the T1600 that can be achieved within the same chassis, just as the T640 could be upgraded to the T1600 (pictured below).

The T4000 is due to ship in the second half of 2011, and will ultimately have multi-chassis capacity, just like the T1600 and T640, though that capability is not being officially announced just yet.

Why this matters
Carriers claim they're desperate to start deploying 100Gbit/s Ethernet ports, and the T4000 gives Juniper a core-network blueprint for transporting all those big Ethernet feeds. (See Verizon Does 100GigE in Europe and EENY 2010: Carrier Wants Cheap 100GigE Now Please.)

The T4000 also lets Juniper continue to claim a leg up on Cisco Systems Inc. (Nasdaq: CSCO) in the ongoing core-router wars. For example, its capacity of 240 Gbit/s per slot (slightly less than what Juniper had announced in February) outdoes Cisco's CRS-3, which has only 140 Gbit/s per slot. Undoubtedly, Alcatel-Lucent (NYSE: ALU) and Brocade Communications Systems Inc. (Nasdaq: BRCD) will still claim they can best Juniper in different ways -- Brocade, for instance, recently claimed 960 Gbit/s per slot on its MLXe -- but Juniper's main talking point remains its comparisons against Cisco. (See Juniper Upgrades the Core, Cisco Boosts the Core With CRS-3, and 100G Watch: Brocade Goes Big.)

For more
Between core-router advancements and 100Gbit/s interest, it's been a busy year. Here's some more reading on the subjects.

Internet2 will be using the T4000 at SC10 as well, but that's part of a backbone demo that involves something like 19 vendors, Ceuppens says.

In any case, I'd go as far as to say that 10...0G is not what will make or break the Future of Internet (or maybe, at most, break it..)

That's I guess what we'll get from having academia 'experiment' new Internet models via Internet2 etc with vendor-sponsored (ie plain commercial) products.

Status Quo ROCKS (pun semi-intentional)!

Sorry, that's the T1600 that's being used in the Internet2 100G demo.  My mistake.

re: Juniper Updates Core Routers

Regarding Next-Gen / Future Internet project like Internet2 using these current commercial generation of IP gear.. Could someone explain what is the connection between plain higher capacity routers (with only incremental feature developments, most of them being reactive to problems with previous products) and Future of Internet?

And where may be the justification of using the resources of Internet2 etc on these less-than-tranformative technology platforms?

Or isn't there any form of actual, concrete innovation happening in the Internet infra space?

This is a most impressive and very important feature:


"existing T640 and T1600 core routers to be upgraded to T4000 without service disruption or changing customer-facing interfaces"

re: Juniper Updates Core Routers

No innovation?  The T4000 is nearly 100x faster than Juniper's original M40 core router released in 1998.


Speeds and feeds may be boring, but its sort of insulting to claim there is no innovation in this product.

Not that far fetched if you plan on this right from the outset. For example, upgrading from QPSK to 8PSK to 16-QAM is a viable technique. Same number of wires, same symbol rate (hence same analog bandwidth requirement from those same wires, which can be 5 years old), but passing a lot more bits per second.

sounds too good to be true technically, lol

re: Juniper Updates Core Routers

Sure, that kind of stuff is important in practice for network ops.

But still, regarding using these commercial routers for Internet2 etc. Future Internet efforts--is there any *industrial* activity going on to transform the Internet to what its major current/future applications would demand from the network, eg per



?? ?  ?   ?

re: Juniper Updates Core Routers

I think "With the Lights Out" has an intersesting point.  For the past decade, there's been an obsession with keeping one's feet on the ground -- the startups and especially the large companies have stressed the ability to upgrade the network without changing out any infrastructure. 

They want to stay pragmatic, since the bad aftertaste of the Internet bubble is still lingering.

So, to answer WtLO's question directly: No.  As far as I know, there aren't any commercial efforts taking the kind of leap you're talking about -- at least, none that are publicly disclosed to the point where a company would be willing to let Internet2 talk to the world about it

I that a problem? Should the router vendors be looking further into the future (they probably are, but -- should they be getting more aggressive about it?)
