I’m not a car person and I don’t worry too much about what’s under the hood. That means that I’m just a car user, I only want to turn the ignition key and drive. In the Data Center world, the server team is typically a user of the network. Server guys don’t want to know how the network is implemented. They just want their VLANs to extend to the whole network so that they can connect their devices with no constraint, without having to worry about high availability, risk containment, link provisioning… network stuff. That’s precisely what FabricPath is designed to offer them: a network that looks like a single switch, the simplest networking entity. This “Fabric” offers efficient any-to-any connectivity with high bandwidth and low latency, all without having to understand how it works.
Of course, this user perspective is an abstraction. The following Figure 2 represents an example of the physical topology of the network, a Clos fabric, typical in Data Center environments. Note that this could just as well be a ring, a star, or even a network distributed across two sites. FabricPath turns an arbitrary topology into a Fabric and does not lock you into a particular model.

What do you get when you combine 5000+ gamers, a 100GE uplink to the Internet, a lot of espresso machines, and no parents to tell them to shut down the noise or go to bed early? A whole lot of fun!
The Gathering (“TG”), is Norway’s largest computer party and kicked off today for its 20th time since 1992. It’s grown so large now that it is held at one of the venues used for the 1994 Winter Olympics. TG continues to attract growing interest to the gaming, computer, and entertainment event, both nationally and internationally and is organized by the non-profit organization KANDU (Kreativ Aktiv Norsk DataUngdom/Creative Active Norwegian Computer Youth). This year it’s powered at record speed by a Cisco CRS-3 router connected to The Gathering’s Internet provider, Altibox at 100 Gbps, along with technical support provided by several of Cisco Norway’s engineers, Merete Asak and Bjornar Forthun.
This isn’t the first time the CRS has played a key role in a Scandinavian gaming conference. The Swedes used our 40G technology in 2007 at their Dreamhack event as we discussed (and video here), but now this has raised the performance bar.
Although they probably won’t be playing Cisco’s award winning myPlanNet game, they’ll still enjoy others such as StarCraft, Quake, and Heroes of Newerth. Participants also participate in creative competitions in programming, graphics, and music.

Last week at the ODVA Annual Conference–as part of ODVA’s announcement of a new energy initiative and white paper–Cisco’s Bryce Barnes roused a packed-house audience representing ODVA’s ~200 industrial and automation suppliers with a compelling speech on the immediate need for Optimization of Energy Usage (OEU™) in the Production domain. Energy consumption statistics for the industrial sector are staggering, most estimates suggesting half of the world’s total delivered energy, and that amount is projected to increase by 40% over the next 25 years. For Manufacturers, energy typically constitutes the first or second highest portion of product variable costs, and most manufacturing companies now report as part of their governance a sustainability strategy that is core to their overall business strategy. Furthermore, volatility of energy markets–closely linked to the stability of governments, international relations and policies–raises the risk profile for continuity of supply, production and satisfaction of customers. Optimizing energy consumption, minimizing energy costs and mitigating energy risks are clearly top of mind business imperatives for the Manufacturing CEO.
Mark Wylie discusses the importance of energy optimization to sustainable manufacturing operations. Check out Mark’s December blog on factory energy management.

Growth in enterprise and consumer services, including cloud computing, video and collaboration services, are some of the key customer trends that underpin many service providers’ decision to further invest in Carrier Ethernet technology. And Tata Communications is no exception.
On Tuesday, Tata Communications, a global service provider and a leader in the Ethernet market, announced that it has selected the Cisco® ASR 9000 Series Aggregation Services Routers to support its new global Next Generation Ethernet Network; and is using the Cisco ASR 9000 to deploy the first global 802.1ah Provider Backbone Bridging (PBB) network.
In plain English, this means that Tata Communications’ customers will benefit by having a larger variety of services delivered with greater scalability, reliability, efficiency.
All existing and new services will be delivered with geographic specificity to minimize latency over a highly efficient network. Migrating to 802.1ah PBB will give Tata Communications a network that can deliver multipoint services more efficiently, while at the same time being able to handle a higher volume of services.
This should be exciting news for Tata’s customers specifically as well as the industry in general. The Cisco Visual Networking Index (VNI) Forecast for 2009-2014, projects that global Internet traffic will increase more than fourfold to 767 exabytes, or more than three quarters of a Zettabyte, by 2014. This amount is 100 exabytes higher than the projected level in 2013, or in other words an increase equivalent to 10 times all the traffic that traversed Internet Protocol Next-Generation Network (IP NGN) in 2008.

Even if you’re a recent member of the SP360 blog audience, you likely know that our flagship edge router – the ASR 9000 – is on my list of favorite things (it makes a great gift idea for the Holidays, btw…), and we’re pleased to report that it is on the lists of many of our largest service provider customers, too. The ASR 9000 has no question made a strong degree traction in the market place in the 18 months since it became generally available and in fact is clearly hitting its stride with a 40% QoQ increase in its customer base last quarter. This traction is not just because of its unmatched capacity in the edge, or its unique capabilities in supporting the services and applications of the Next Generation of the Internet, but also because of its high degree of resiliency and quality – prompting many customers I speak to, to continue to rave about it.
In addition to all this traction, contributing to some nice market share gains for Cisco – an increase in 2.7% in edge share in CYQ3 alone per ACG Research – we’re just as pleased with what the ASR9000 can do to support our service provider customers. To that end, we’re honored to announce the addition of Tata Communications to the list of prominent, reference customers.
