Cisco compacts Catalyst switches

New C-series line targeted at wiring-constrained environments
Cisco this week is rolling out two lines of Catalyst Ethernet switches in compact form factors intended for deployment in workgroups closer to users vs. wiring closets.

The Catalyst 3560-C and 2960-C Compact Series (C-Series) switches are designed to extend connectivity to IT deployments outside of the wiring closet -- customer check-outs, kiosks, warehouses, conference rooms, classrooms, hotel rooms, cruise ship cabins, gaming floors and other space- and wiring-constrained networking environments.Cisco says this market is about $1 billion and is being underserved by low-end, commodity switches. The C-series are “enterprise-class,” and carry all the features of the higher-end Catalyst 3560 and 2960 switches, but in a compact form factor, says Rob Soderbery, senior vice president and general manager, Ethernet Switching Technology Group at Cisco.
So the C-series will compete with both low-end commodity switches and enterprise-class compact switches from Cisco’s traditional competitors in the enterprise and SMB switch market – HP, Adtran, Netgear, D-Link, etc.

The switches are comprised of five models. They sport eight to 12 Fast Ethernet and Gigabit Ethernet ports, and two Gigabit Ethernet uplinks. They also include hardware acceleration for IPv6, IP multicast and access control lists.

The switches feature what Cisco calls Power over Ethernet (PoE) pass-through, a capability that allows the products to draw 30 watts/port of power from PoE switches deeper in the network – like in the wiring closets -- and not require dedicated power outlets or power supplies. The switches are also designed to reduce cabling costs by eliminating the need for individual cable drops from the wiring closet to far-flung network endpoints.

The switches can be deployed up to 100 meters away from the wiring closet, Cisco says. They are fanless, and can be placed on or mounted underneath desktops and countertops or on a wall.
For security, the switches support Cisco’s TrustSec technology, which determines, through policies, the role of users and devices in the network before granting access to resources. The C-Series switches are also PCI compliant, Cisco says, for regulatory compliance of payment transactions.

The switches encrypt all packets between the switch and the end device, and malicious users can be blocked from eavesdropping on the conversation between two endpoints, Cisco says. The switches also come with an optional security lock and cable guard to prevent theft of the switch and unauthorized access to the cables.
The C-Series switches also feature tools for simplified configuration and management, and QoS implementation for IP telephony and video. The switches can be remotely managed along with the switches in the wiring closet, Cisco says.

They also support Cisco’s EnergyWise software for monitoring and managing energy consumption of the devices connected to the switch. EnergyWise turns off or powers down devices when they are not needed.
"This is a long, overdue and good move by Cisco," says Andre Kindness of Forrester Research. "The retail and education markets that have always had a need a for smaller, more efficient, and quieter switches which has been traditionally filled by D-Link, HP and 3Com" before HP’s acquisition of them.

Kindness says Cisco is responding to trends in retail, education and enterprise in general where users are moving to more a distributed workforce with smaller campuses and more branch/remote locations. This means there will be shift in edges switches from large 24 and 48 port ones to compact and fanless ones, Kindness says.

Businesses are also setting themselves up in more locations but with smaller footprints to connect with more customers, Kindness says. An example of this is banks that have carved out locations within grocery stores instead of leasing large buildings on the corner of major streets.

The strengths of Cisco's C-Series line are simplicity, security and deployment flexibility, Kindness says. The downsides may be price and feature overkill for some markets.
"They are packing all the features into each physical form factor instead of offering different firmware levels for each form," Kindness says. "For example, the education market doesn’t really need the security rich feature set as the retail industry."

The switches may also overlap with Cisco's 500 series switches for the SMB market, Kindness says. Cisco may need to do a better job articulating the differences between these and other offerings, he says.

Pricing for the C-series ranges from $745 to $1,995. They will be available in March.

Cisco unveils next Internet core router

Says its CRS-3 has three times the capacity of its current version
Cisco Systems today introduced its next-generation Internet core router, the CRS-3, with about three times the capacity of its current platform.

"The Internet will scale faster than any of us anticipate," Cisco Chairman and CEO John Chambers said during a webcast announcing the product.

At full scale, the CRS-3 has a capacity of 322Tbit/sec., roughly three times that of the CRS-1, which was introduced in 2004. It also has more than 12 times the capacity of its nearest competitor, Chambers said.

The CRS-3 will help the Internet evolve from a messaging to an entertainment and media platform, with video emerging as the "killer app," Chambers said.

Using a CRS-3, every person in China, which has a population just over 1.3 billion, could participate in a video phone call at the same time. It could transmit the whole printed contents of the Library of Congress in one second and every movie ever made in four minutes, according to Cisco.

"This is the heart and brains of the next-generation Internet," said Suraj Shetty, vice president of worldwide service provider marketing.

Also on the webcast, AT&T announced it has been using the CRS-3 to test 100Gbit/sec. data links in tests on a commercial fiber route in Florida and Louisiana. The router will be available in the third quarter this year.

Cisco touts new core router's 100G Ethernet, energy efficiency

Cisco's new CRS-3 core router, which the company has boasted will "forever change the Internet," will come with 100Gbps Ethernet interfaces and 322Tbps multichassis interconnect capability.

The router also will support software to help make data center and cloud computing resources more available to users, and will use 60% less power than its predecessor, the CRS-1, said Mike Capuano, Cisco's director of service provider marketing, in an interview following Tuesday's announcement.

Cisco expects to ship the 120G per slot system, which has three times the capacity of the CRS-1, in the third quarter.

100G Ethernet cheat sheet

Some wonder whether such capacity claims are all that meaningful, however, in that Cisco never really delivered on it 92Tbps promises with the CRS-1. The largest CRS-1 multichassis deployment connects eight CRS-1s into a 10Tbps system, Capuano acknowledges.

So will any carrier really need a 322Tbps system any time soon?

"We're continuing to increase the size of our multichassis deployments at a pace where we're meeting customer demand," Capuano said. "We don't want to get ahead of them; we have to time it so that we're delivering the right set of capabilities as time progresses. It's all designed in from the beginning."

Capuano also said all CRS-1 modules are forward compatible with the new router.

The CRS-3 delivers the industry's most energy efficient core router, according to Capuano. It consumes 2.75 watts/gigabit, almost half that of rival Juniper's 4.4 watts/gigabit on the T1600, he said.

The single port 100G Ethernet interface for the CRS-3 supports "singleflow" 100G transmissions through Cisco's QuantumFlow Array chipset. It transmits a single 100G flow while other 100G Ethernet interfaces take two 50G forwarding engines and multiplex traffic across them, Capuano said.

"That makes it much harder to do a multichassis design," he said.

For delivery of data center and cloud services, the CRS-3 supports Cisco software called Data Center Services System. The software detects changes in traffic patterns of workloads between data centers and locates the best path to access compute and storage resources, or content. It works with another attribute of the Data Center Services System software called Cloud VPNs to set up a secure MPLS connection between data centers to balance workloads.

"That's a big part of this next generation Internet -- the emergence of cloud," Capuano said. "It requires scale, savings and service intelligence."

Cisco quits WiMax radio business

The company will stop making base stations to concentrate on back-end IP infrastructure by Stephen Lawson

Cisco Systems will stop developing and making WiMax base stations to concentrate on the IP (Internet Protocol) networks that sit behind them.

Cisco acquired Navini Networks, which made WiMax RAN (radio access network) equipment, in 2007. The dominant IP networking company said at the time that it saw a powerful opportunity to bring broadband Internet access to developing countries through WiMax.

However, despite hitting the market first, WiMax has taken a back seat to LTE (Long-Term Evolution) as a 4G (fourth-generation) mobile technology. LTE is backed by the industry body behind GSM (Global System for Mobile Communications) and is on the road maps of most major carriers that have chosen a 4G system. In the U.S., Verizon Wireless plans to launch LTE commercially this year and AT&T will follow next year.

Cisco can serve both markets with products it acquired through its purchase last year of Starent Networks, which made gateways between radio networks and a carrier's core IP infrastructure. Both WiMax and LTE are based on IP packet networks. In order to concentrate on this business, the company will get out of making the actual radios that deliver WiMax signals to subscribers' devices.

"Cisco's mobile strategy has always been to provide a radio-agnostic approach that focuses on the packet core and IP network, where the company can add differentiated value. After a recent review of our WiMax business, we announced a decision to discontinue designing and building new WiMax base stations and modems, and we also announced a support plan for transitioning existing customers," Cisco spokesman Jim Brady said Friday.

The Navini products haven't played a big role in high-profile WiMax networks. Cisco is a supplier to the world's largest WiMax network project, Clearwire's national U.S. buildout, but only with IP equipment, not radios.

Analysts called the Starent acquisition a move away from WiMax toward the larger LTE market. Unlike WiMax, which had its roots in the wireless LAN world, with strong backing by Intel, LTE is dominated by the giants of cellular equipment, such as Ericsson and Alcatel-Lucent. Cisco has said it does not intend to compete with those types of vendors.

Analysts were not surprised by Cisco's announcement.

"Cisco pulling out at this moment looks like good business," said analyst Laurence Swasey of Visant Strategies. He believes LTE will dominate the 4G world and may even be adopted by current WiMax carriers eventually.

Cisco did the WiMax industry a big favor by buying Navini, Swasey said. "It was a stamp of approval at a time when the market was very fragmented as to what 3.5G and 4G would be to the masses," he said. Today, several major vendors, including Huawei, Samsung and Motorola, are supplying RAN equipment for commercial networks. Cisco's decision to get out of the business will have far less impact than its choosing to get in, Swasey said.
