Huawei uses CloudEngine switches to make enterprise network mark
Huawei has made an aggressive move in the enterprise data center space with the introduction of the CloudEngine series of switches. The company touts the CloudEngine switches as possessing the largest single-frame switching capacity -- up to 48 Tbits.The CloudEngine series offers high-density switching of 100 Gigabit Ethernet (100GbE), 40GbE, 10GbE and GbE interfaces to support virtualization as well as computing, storage, and network convergence. The CloudEngine series includes the CE12800 core switches as well as CE6800 and CE5800 top of rack switches.Huawei asserts the following features should ensure the CloudEngine switches make an impact: A non-blocking CLOS fabric architecture and large distributed buffers efficiently process traffic bursts. An improved power and cooling system that includes a front-to-rear ventilation channel design improves heat issipation. The Cluster Switch System (CSS) feature enables virtualization of multiple switches into one logical switch. The Virtual System (VS) feature enables virtualization of one switch into multiple independent logical devices. Support of virtual machines by enabling network administrators to build large-scale Layer 2 networks with over 500 nodes based on TRILL – the Transparent Interconnection of Lots of Links standard from the Internet Engineering Task Force (IETF). This feature supports fast migration and flexible service deployment, Huawei says. Meanwhile, with the use of the nCenter network management system, the CloudEngine series can achieve more than 10X the virtual parallel processing capability of the industry average, Huawei claims. Fibre Channel over Ethernet (FCoE) support, as well as the ability to combine Priority Flow Control (PFC) with Enhanced Transmission Selection (ETS) to ensure non-blocking transmission.

Verizon unveils new optical network strategy
Verizon (NYSE, NASDAQ: VZ) has confirmed its intension to deploy 100-Gbps in its metro networks, as well as strengthen its network control plane, as part of an announcement covering its upcoming global optical network initiatives.Ihab Tarazi, vice president of global IP and transport planning and technology for Verizon, told attendees at the OSA Executive Forum this past March that he expected to begin rolling out 100-Gbps technology in the metro next year (see “Verizon looking at 100G in the metro next year”). Tarazi said that Verizon would use dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection, rather than the 4x28-Gbps technology several vendors have suggested would be a lower-cost approach (see, for example, this video interview with Christoph Glingener of ADVA Optical Networking). Tarazi said he was interested in having a common approach to 100 Gbps in the metro and long haul portions of Verizon’s network.Meanwhile, the control plane upgrade will come in the form of the Optical Transport Network (OTN) capabilities in the Ciena 5430 Reconfigurable Switching System Verizon is deploying in its network. (In fact, both initiatives are good news for Ciena, which is also Verizon’s primary supplier of 100-Gbps technology.) Verizon says the OTN functionality will enable it to extend its mesh architecture initiatives.

Cisco strikes cautious note for fourth quarter
Cisco (NASDAQ: CSCO) reported record revenues in its fiscal third quarter, which ended April 28. However, company management indicated that macroeconomic conditions, particularly in Europe, continue to hamper its progress.Cisco accrued net sales of $11.6 billion and GAAP net income of $2.2 billion ($0.40 per share). Both figures exceeded consensus financial analyst predictions. The revenue number represented an increase of 7% year on year.John Chambers, Cisco’s chairman and CEO, took the opportunity on a conference call with analysts to tout the performance as a sign that the shift in strategy he launched last year (see “Cisco: Layoffs are coming”) is working.“We believe our vision and strategy are working. Our value proposition and mindshare with our customers are very strong,” Chambers said. “One example would be our traction and relative performance with our service provider customers, which represents about a third of our total business and where we believe we have taken wallet share almost across the board. We remain number one or number two in almost every product market where we play. At the same time, we have maintained or gained share year-over-year in the majority of product categories across service provider, commercial, and enterprise in the most recent quarter for which the market share data is available. Additionally, we are often named the top IP vendor by our very important channel partners.”While the optical portion of Cisco’s activities saw the finalization of the Lightwire acquisition during the quarter, overall the segment had a rough three months. Revenues for the optical product line decreased sequentially, offsetting gains from other elements of Cisco’s NGN Routing segment to leave that business sequentially flat.Looking forward, Cisco sees a few sources of headwinds. One is Europe, where product orders were flat during the quarter, despite gains in Russia and emerging markets in the region. “We have seen the issues of southern Europe expand. Central and Northern Europe have their own set of challenges,” Chambers said.“As you have seen in our enterprise order growth and the trends over time, we are seeing a hesitant spending environment,” Chambers added later, although he immediately said this customer space had not presented the company with any new challenges, nor had the space experienced a downturn. “We are seeing longer sales cycles, more signoff, and smaller deal size,” he clarified. “Again, but is all focused in terms of a more cautious environment and uncertainty from a CEO perspective.”
