In the lucrative land of data networking, Cisco Systems, with double-digit annual growth and revenue surpassing $8 billion in 1998, reigns as the undisputed king. But there's mounting evidence that all may not be well in the upper reaches of the kingdom. Unprecedented challenges from upstarts in the router market, coupled with an uncharacteristic move by Cisco to pull the plug on a next-generation switch, suggest that the crown may indeed be resting a little uneasily on the sweet spot of Cisco's product line - high-end data networking equipment for the core of the public network.
While no one is suggesting Cisco's empire faces significant or immediate peril, analysts say that the sun could be setting on the company's days of dominance in the high-end routing and switching arena.
"I do not expect Cisco to go out of business tomorrow," says Joe Skorupa, an analyst at Ryan Hankin Kent, which tracks the network equipment market. "However, the company is under pressure that it hasn't experienced in a long time."
Most of the pressure on the router front is coming from a gaggle of start-ups on the verge of shipping products that will move packets of data based on Internet Protocol (IP) at rates far exceeding the abilities of Cisco's most powerful router. Even an expected upgrade to Cisco's 2-year-old GSR 12000, which quadruples the performance of its predecessor, falls many times short of the proposed speed and capacity of products in the works from Avici Systems, NetCore Systems, Pluris and Nexabit Networks, acquired late last month by network equipment kingpin Lucent Technologies.
And while this quartet of next-generation wannabes poses only a potential threat to Cisco's high-end networking crown, a more immediate challenge is being waged by Juniper Networks, which has been shipping gear competitive with the GSR 12000 and taking business away from Cisco since September 1998 and which turned in a wildly successful initial public offering (IPO) in late June.
"Juniper is taking a lot more market share than Cisco expected," Skorupa says, adding that Juniper's M40 Backbone Router is deployed in the core of several major carriers, including Cable & Wireless and UUnet Technologies, one of the world's largest Internet service providers. "The word from several service providers is that Juniper's product is easier to install and operate."
Frontal assaults
Part of Cisco's dilemma is its push to dominate the entire networking landscape. Cisco has spent much of the past few years broadening its product portfolio to do battle with established telecom equipment suppliers Lucent and Nortel Networks. As a result of those efforts, Cisco is now diversified enough to survive a minor turf invasion at the high-end of the data networking market. But industry observers say that maintaining control of the core of the public network is crucial to Cisco's long-term goals.
"This is the core of what Cisco calls the New World network," says David Passmore, president of market research firm NetReference. "This space is strategic to Cisco. It is not willing to give it up."
Besides the strategic setback, Cisco could miss a big financial payoff if its rivals loosen its grip on the core of carrier networks. Although it is currently valued at only about $170 million, the core switching and routing market could swell to more than $5.5 billion by 2003, according to Ryan Hankin Kent.
The sizable surge in revenue is based on the tightly intertwined relationship between sales of backbone routers and the runaway growth of the Internet, which is doubling in size every six months, according to even the most conservative estimates. As traffic expands across the backbone, service providers must constantly replace equipment deployed at the core with bigger and faster gear.
While this situation is good news for equipment makers, service providers are looking for relief from frequent and costly forklift upgrades. Even if they are able to redeploy high-end routers and switches at the network edge, service providers are forced to replace network gear long before it can collect dust - or a return on investment. To break this perpetual upgrade cycle, carriers are looking for high-end gear that can accommodate growth spurts beyond 18 months to two years, Skorupa says.
Designed from the ground up for deployment in carrier networks, routers from Avici, NetCore, Nexabit and Pluris are fortified with expandable switching fabrics that enable service providers to increase bandwidth capacity simply by adding another module to the existing router. The Pluris Terabit Network Router, for example, can expand from a capacity of 90 gigabits per second to more than 180 terabits per second, says Sam Halabi, vice president of marketing at Pluris.
In contrast, Cisco's GSR 12000 is a stand-alone device that has a maximum switching capacity of 60 Gbps. And with the 2-year-old product able to provide only 11 OC-48 (2.5-Gbps) connections, the accelerated growth of data traffic has already relegated the GSR 12000 to the role of an edge device, Cisco's rivals say.
That's a categorization that Tony Bates, director of marketing for the optical internetworking business at Cisco, firmly rejects. "Just because the Internet is doubling every six months doesn't mean you need a new box with a higher magnitude of performance every six months," he says. "This is not about building terabit boxes. This is about building terabit networks."
According to Bates, the key to accommodating Internet growth is to deliver technology that lets service providers distribute capacity across the network. Leveraging Cisco's Internetwork Operating System as a mechanism for harnessing the collective capacity of Cisco's routers, service providers can build terabit-scale networks with gigabit-size building blocks, Bates says. "The thing is the scope of those networks," he adds.
Although Bates says Cisco will continue to expand the capabilities of its core router, it will do so at a pace that meets the demands of its customer base. In his estimation, the GSR product line will continue to fit the bill for the foreseeable future.
But Cisco's competitors see things differently. Endorsing the formula of constructing terabit networks with terabit-size boxes, Nortel has a 20 percent stake in Avici, although a reseller agreement between the two was terminated late last month to give Avici some freedom to pursue a possible IPO.
Lucent made its move into the terabit market in late June, with its announced purchase of Nexabit. Even the European players think there might be some substance to this terabit router thing. Siemens purchased Argon Networks, a high-end router start-up, in March to be part of its new Unisphere Solutions operation.
Cisco's vulnerabilities aren't limited to the terabit router market. In the Asynchronous Transfer Mode space, which is expected to be another source of equipment for builders of next-generation networks, Cisco has shown some signs of sputtering. Suffering a major public relations setback earlier this year, Cisco pulled the plug on its high-end ATM product, the core switch it unveiled amid much fanfare a year earlier. Several industry observers blame the misstep on Cisco's internal development team. "It's no secret that the integration of StrataCom has been a miserable failure," says a network architect of a major carrier who asked not to be identified, referring to Cisco's $4 billion purchase of the ATM and frame relay equipment maker in 1996.
The setback could further erode Cisco's market share in the ATM backbone arena. According to market figures from Dataquest, Cisco saw its share of the ATM backbone market decline slightly last year, as Ascend Communications - now part of Lucent - jumped to the front of the pack.
What's going on Market watchers are floating a few theories as possible explanations for Cisco's apparent problems at the high end of the router and switch market.
The one that holds the least stock with industry experts is that Cisco is a victim of its own success. Similar to Microsoft and other companies with double-digit growth rates, Cisco has suffered its share of brain drain.
Software engineer Tony Li, who played a critical role in the development of Cisco's routing technology, was perhaps the most respected technical mind to depart for greener pastures. While at Cisco, Li earned the loyalty of several service providers with his extensive knowledge of complex routing algorithms and his ability to quickly solve problems that cropped up in Cisco's gear. Li left Cisco for Juniper a few years ago, where he contributed significantly to Juniper's well-regarded routing software. He recently left Juniper to pursue new interests.
A second theory about Cisco's apparent vulnerability is that the recent and sudden diversity of Cisco's product line could be pulling attention away from the company's core competency.
"They are waging battles on multiple fronts," Ryan Hankin Kent's Skorupa says. "Cisco is simultaneously engaged in battles where it is the biggest competitor - the IP core router market - and in markets where it is not the leader."
Skorupa is referring to Cisco's epic struggle to compete in the full-service business with telecommunications equipment giants Lucent and Nortel and European powerhouses, such as Alcatel, Ericsson and Siemens. By trying to make up ground in the voice, telephony, cable modem, Digital Subscriber Line modem and call-center markets simultaneously, Cisco could be falling a step or two behind in the router segment.
But then again, Cisco is Cisco, a Silicon Valley bully famous for locking corporate customers into proprietary strangleholds. A point of tremendous frustration for rivals - many of which no longer exist - it was not uncommon for Cisco-based customers in the enterprise market to purchase Cisco hardware that was 10 times the cost and six months behind competitive products.
But customer loyalty will not stretch as far in the highly competitive and technically sophisticated service provider market, Cisco's newest set of rivals say. "The carrier space is definitely different," says Pete Chadwick, vice president of marketing at Avici. "It remains to be seen if Cisco understands the carrier market when its strength comes from the enterprise."
Several analysts believe that Cisco is not concerned with pushing the envelope beyond its current high-end products because of the impending collision between electronic equipment, such as routers and switches, and optical networking gear.
Cisco is already well-protected should the core of the public network go all optical, says Tom Nolle, president of research firm Cimi. The company recently took a stake in Monterey Networks, which makes optical equipment designed to switch wavelengths of data across long-haul networks.
In the end, however, Cisco's best defense against losing the high end of the router market is its deep pockets and willingness to dig into them from time to time. "Cisco always reserves the right to buy someone," consultant Passmore says. "They can always whip out the old checkbook."
