Cisco Makes Metro Move

Cisco Systems Inc. (Nasdaq: CSCO) upped the ante in the metro network market this week with the announcement of the 7600 Optical Switch Router (OSR), a product that will compete with switch-routers from Extreme Networks Inc. (Nasdaq: EXTR), Foundry Networks Inc. (Nasdaq: FDRY), and Riverstone Networks, as well as edge routers from Juniper Networks Inc. (Nasdaq: JNPR) (see Cisco Announces New Router).

Big news? Yes and no. On the one hand there is nothing really new about the 7600 OSR. It's actually a combination of the switching fabric of Cisco's existing Catalyst 6500, mixed in with the Layer 3 IOS routing software from its olde worlde 7500 router. The resulting hybrid is garnished with some new and faster ATM, packet over Sonet (POS), and gigabit Ethernet interfaces at speeds ranging from OC3 (155 Mbit/s) to OC48 (2.5 Gbit/s).

“It's basically a Catalyst 6500 enterprise L3 switch that's been re-purposed to be used in the metro service provider space, like many of the other Layer 3 boxes” says Dave Passmore, research director for the Burton Group.

Cisco acknowledges that the 7600 OSR combines technology from these two product lines, but it emphasizes that it has added new features specifically for the carrier market.

“The OSR is really an extension of our routing products and allows customers to migrate to optical speeds,” says Chris McGugan, senior manager of marketing for Cisco’s Internet systems business unit. “It also provides very rich, high touch optical services that providers need.”

Some analysts like Deb Mielke, principal at Treillage Network Strategies Inc. see the new 7600 OSR as a way to fill in the gap between Cisco’s large GSR 12000 routers in the core, and the older and slower 7500 routers -- which are usually deployed in service provider points of presence (POPs). With a 256-Gbit/s switching fabric and a 30 million packet per second (pps) forwarding engine, Mielke sees the architecture working well to fill this need.

But others read the introduction of the 7600 OSR as a sign.

“Cisco seems to have finally acknowledged that the 7500 router has become obsolete for service provider networks,” says Passmore.

The new 7600 OSR can be used for basic metro aggregation, using the cheaper, high-density Catalyst 6500 interfaces, or it can be used in place of the 7500 for edge routing in a POP -- performing more advanced billing, traffic shaping, quality of service, and accounting. Cisco says that even with all these fancy features turned on, the 7600 OSR can still route at wire speed due to its Parallel Express Forwarding processors.

One advantage of the 7600 OSR’s familiar architecture is that the new chassis accepts line cards from both the Catalyst 6500 product family as well as the 7500 router. This will help users retain value in existing equipment.

“Cisco has done a great job at leveraging components from both the 6509 and the 7500 for the new box,” says Chris Kozup, research analyst with Meta Group Inc.. “If you look at the past [Catalyst 8540 and 5500] there has been little investment protection for customers wanting to move to the next-generation box.”

But there are some downsides. For one, the device doesn’t offer multiprotocol label switching (MPLS) in the first release. While many pundits point out that MPLS is still in its early stages of adoption, competitor Riverstone has already announced support for this feature in its metro products (see Riverstone Scores a Coup).

Another feature missing is support for resilient packet ring (RPR)-like protocols -- including Cisco’s own Dynamic Packet Transport (DPT) -- that will provide protection on ring-based topologies. Even though RPR hasn’t been standardized yet, the GSR 12000 and the 7500 platform both support DPT.

“ I believe the reason Cisco hasn't included MPLS or DPT in this release is due to the fact that they wanted to get this box to market so as to not lose customers,” says Kozup. “The Catalyst 6509 wasn't able to compete on the same level with competitive products from Extreme, Riverstone, and Foundry.”

re: Cisco Makes Metro Move "Will be" "will be" I think the deficiencies are explicit. Unless you consider non-existant or non-compliant features posing as current features OK. But then you'd be working for Cisco, wouldn't you?

re: Cisco Makes Metro Move I have to apologize for SmartBoy... he is upset because his stock options are worthless... try building a real product next time..

re: Cisco Makes Metro Move To my dear colleagues at Cisco:
If you haven't put it together already, we should be advertising on this site.
The "accuracy" of LightReading's coverage will improve enormously, and our record of 5 for 5 negative articles should turn in the other direction.
Stan 12/4/2012 | 8:51:09 PM
re: Cisco Makes Metro Move I hate to admit it, but I agree with this message to Cisco. Though I don't think advertisers are the only ones who receive preferencial coverage. It is also companies backed by LIGHTSPEED (do the research folks)

Steve Saunders will write an occasiional postive article about a non-LS company to cover his tracks, but Lightreading is a joke, and anyone who reads it should know most every article is based on heresay, innuendo, gossip, rumors...and, yes, VESTED INTERESTS.

LIGHTREADING IS A BUSINESS NOT A MAGAZINE.

Sorry Stevie baby. Truth hurts I bet.

I also reccomend that all LIghtreading
advertisers pull out now and back a new publication. Any journalist with a fair amount of credibility should be drooling at the opportunity to launch a new optical networking web magazine.

re: Cisco Makes Metro Move If you wanted all of that wouldn't you just call Village Networks?

"Just because you plug fiber into the box doesn't make it an OPTICAL SWITCH. POS and GigE and ATM on glass are wicked old shit, get with the program and do some hard shit like switching IP to Lambda's or DWDM switching, etc."
ExNortel 12/4/2012 | 8:51:07 PM
re: Cisco Makes Metro Move So, what's so optical about it? No DWDM, no Lambda switching, nothing intelligent...just more packet interfaces, and probably half line rate at that, again.

Optical Switch Router = POS interfaces...yawn.

<sarcasm on="">

</sarcasm>

When will you guys learn...yawn yawn yawn....more of the same.

Even Nortel is working on more complex stuff than this....like OPC (-O-nly a -P-aper -C-oncept) which is packet to lambda directly.

Not sure if we'll see it though before Roth loses his job and all the law suits come to an end (5 years or so) for all that nasty stock stuff over the last few weeks. EEEGADDDSS!

"Optical Switch Router = POS interfaces...yawn."

I thought, OSR meant Optical "Services" Router...

never...

snicker.....

Yeah when Nortel or anybody for that matter figures out how to map an IP address to a photon for transport over lamdas, I'd be impressed. What does Nortel call this address a PAC(Photon Access Control) address?....

I'm pretty sure Nortel is a lot closer than Cisco is to making this happen considering their extensive and impressive track record with IP...

re: Cisco Makes Metro Move Hi SteveS:

You are joking about advertising, right? I do not think we should be advertising.

This Lightreading group may be in alot of hot water soon. I hold one of the equipment vendor rotating seats on the Carrier Relations Committee, and I found out after one of our sessions recently that at least a few service providers have sent several complaints to the FCC about Lightreading. Some agency within the FCC is looking into the complaints. If they decide to move on the complaints, it is not going to be fun to be Lightreading, or a Lightreading investor or advertiser.

We have helped build so much of the internet. Let's stick to our business, and ignore all of the lies that these guys write. Let these guys whither on the vine.

You are correct.
It is not an optical switch.
