Evolving Provider L2VPN Services with E-VPN

A team of us at Cisco has been working, together with industry colleagues, on defining and standardizing a new Layer 2 VPN solution known as Ethernet Virtual Private Network or E-VPN. In this post, I will discuss the key requirements that helped shape this solution, and attempt to shed some light on the drivers for the technology and how it enables the evolution of Service Provider L2VPN offerings.

How Coherent Is Your Network? Ours Go To 11.

This is Fiber Tap?  Light Reading.com had an interesting article recently on the potential impact of coherent optical technology on submarine cable capacity, which in many cases was built for the old “10 Gbps Information Super Highway”.  Today, the Internet is much more than that, with mobile, video, and cloud services dominating growth.  The key point is that new technology is enabling existing systems to be easily upgraded from 10 Gbps to 40 Gbps and 100 Gbps simply by replacing the DWDM equipment, without the cost to deploy new cable and other costly fiber infrastructure. As a result, companies which specialize in undersea cable deployments face economic challenges because of the lack of needed new projects. Why buy new when you can supercharge existing assets, especially in this economy?

We’ve seen this trend to Read More »

Breaking Barriers with SIP Trunking – Cisco Emerges as Market Leader in New Infonetics Market Share 2012 Report

The way that enterprises connect to the outside world is changing. The transition to voice over IP (VoIP) that began with enterprise networks a decade ago, is now in full force in service provider networks. In a report issued on Monday, Infonetics Research reported that Cisco, the global market leader for unified communications and collaboration, is now the new market leader in global enterprise session border control (SBC) solutions for the first half of 2012, providing secure IP connectivity from the enterprise edge to the service provider session initiation protocol (SIP) trunking service.

Why is this so important? Service providers are now offering SIP trunking services instead of legacy dial tone (also known as time-division-multiplexing or TDM) to connect to enterprises of all sizes, including small businesses. In fact, according to their 2012 VoIP and UC Services Report, Infonetics forecasts SIP trunks to grow over 66 percent in 2012 alone.  Customers are quickly embracing the new technology, which offers substantial cost savings and the promise of extending real-time rich-media collaboration applications beyond the enterprise to customers, partners and suppliers.

To begin realizing the benefits of SIP trunking, businesses need to deploy a session border controller in order to efficiently and securely connect to service providers while preserving voice quality and features. Session border controllers connect IP networks and provide session control, security, demarcation for better troubleshooting and interworking to help overcome differences in the deployment of the SIP standard (such as CODEC or signaling).

Cisco reinvents the collaboration edge

Cisco’s session border controller, called, Cisco Unified Border Element (CUBE) is a software license add-on to the widely deployed Cisco Integrated Services Routers (ISRs) and Aggregation Services Routers (ASRs). CUBE provides significant benefits over competitors’ stand-alone session border controller offerings.  For example, CUBE enables customers to transition more smoothly to SIP trunking while reducing costs and operational complexity, often requiring no new hardware to be purchased or deployed. As a result, CUBE has been adopted by over 5,000 customers in 160 countries.

In their report, Infonetics credited Cisco’s differentiated model for delivering SIP trunking service, stating: “This is a natural extension of Cisco’s dominant market position in the router market—the majority of organizations have Cisco routers already installed and deployed at the important network border points.”

Other benefits of CUBE include: Read More »

Updated Global Cloud Index: Revised Forecast Shows Clear Signs of Continued Data Center Virtualization

Today, Cisco released its first update to the Cisco Global Cloud Index (GCI), covering the 2011 to 2016 forecast period. This annual report is our ongoing effort to predict the growth of global and regional data center and cloud-based IP traffic as well as analysis of the trends associated with data center virtualization and cloud computing. Here are just a few of the key projections in this year’s report:

Global data center traffic

  • Global data center IP traffic will increase nearly four-fold over the next 5 years (reaching 6.6 zettabytes by the end of 2016). Overall, data center IP traffic will grow at a compound annual growth rate (CAGR) of 31 percent from 2011 to 2016.

Data center virtualization and cloud computing transition

  • By 2016, nearly two-thirds of all data center workloads will be processed in the cloud (as opposed to less virtualized traditional IT servers). In 2011, 30 percent of workloads were processed in the cloud, with 70 percent being handled in a traditional data center.

Global cloud traffic

  • Global cloud IP traffic will increase six-fold over the next 5 years (reaching 4.3 zettabytes by the end of 2016). Overall, cloud IP traffic will grow at a 44% CAGR from 2011 -- 2016.
  • Global cloud IP traffic will account for nearly two-thirds of total data center traffic by 2016.

And this year, we’ve added more forecast granularity—projecting cloud traffic (and other metrics) for all six global regions: Read More »

All (Optical) Roads Lead to Monza: Join us for Fall PONC 2012

As we look forward to holding our Fall Packet Optical Networking Conference (PONC) in Monza Italy (November 14 and 15, 2012), our thoughts go back to the Spring event earlier this year.  Over 150 customers from more than 50 companies attended the PONC in Richardson Texas – a 50% increase over 2011, and we’re expecting another terrific turnout in Italy. The theme in Richardson was Convergence, referring to the elimination of layers (whether those are IP or optical layers), the elimination of interconnects between those layers, and simplifying operations. Our attendees therefore had an early view – a peek “behind the curtain” if you will -- on the concepts and technologies that were key components of the recent Cisco Elastic Core solution announcement which featured our new nLight technology.

Since our customers consistently ask us for Read More »
