A Healthy Potential

Virtacore, a leading cloud services provider, aims to help clients shift to the cloud. But the company was aware that in order to help others, it first needed to help itself—which meant updating its own infrastructure to provide the best IT-as-a-Service (ITaaS)  to customers.

By leveraging innovative technology from Cisco, like the Cisco Unified Computing System (UCS), based on Intel® Xeon® processors, Cisco Nexus Switches, and Cisco Catalyst Switches, Virtacore is now able to better leverage its internal IT to perform faster, more reliably, and on a larger scale. And, in turn, the company gained the ability to provide more cost effective, higher-standard services externally.

Reducing deployment from six weeks to just a few hours, providing a single-pane-of-glass management, and ensuring improved performance are a few of the benefits that have confirmed the worth of implementing new technology and rebuilding the IT environment.

Read the full article and learn just what Virtacore did to unleash their IT potential – and how they can continue to do so in the future.

Satellite Communications Come to the Mobile Internet Services

The mobile satellite communications market is experiencing strong growth globally with mobile workers, cargo, and remote applications driving the industry. This diverse market consists of handsets, modems, ships, human passengers, and machine-to-machine (M2M) modules that bring satellite services to a diverse range of applications, further driving rapid traffic growth and bandwidth demand from machines and humans alike.

As a result of this, however, Satellite Communications (SATCOM) service providers are straining to keep up with this tremendous demand and growth. They are challenged to seamlessly integrate with terrestrial networks, and as if this is not enough, much like the similar challenges faced my terrestrial mobile operators, they also need a solid plan for how they will address the data traffic explosion coming onto their networks in the next three to five years.

Simplifying Multi-Provider WAN Designs

This week, at Cisco Live Orlando, we are introducing a brand new EIGRP feature called Over-the-Top (OTP). EIGRP OTP is focused on simplifying the deployment of branch networks utilizing an EIGRP end-to-end solution over public and private networks. This simplicity is further enhanced with EIGRP use of Over-the-Top (OTP) to support multiple service provider IP networks.

Connecting sites over a WAN cloud can be complex, especially when supporting thousands of branch locations, multiple service providers, and feature requirements like encryption. Aside from the configuration challenges, operationally, customers need to filter routes while avoiding routing loops during redistribution, which makes it harder to troubleshoot the network.

The EIGRP Over-the-Top (OTP) solution simplifies multi-provider IP WAN network designs. It simplifies the interface with the WAN providers and facilitates an end-to-end EIGRP network, which is easier to troubleshoot.

How simple is EIGRP OTP to deploy? Read More »

Hitchhiker’s Guide for Service Providers at Cisco Live Orlando

Amrit Hanspal Formal photoWritten by Amrit Hanspal, Sr. Product Manager, Service Provider Segment Lead, Network OS Tech Group

Cisco Live at Orlando in 2013 offers a host of opportunities if you are a service provider or a large enterprise that offers services to internal groups. Watch out for the following five key areas and the respective speaking sessions when it comes to software capabilities of the Routing & Switching platforms—(1) IPv6, (2) SDN, (3) Core IP & Optical, (4) Ethernet Access & Aggregation and (5) IP Routing.


June 2012 officially marked the IPv6 Internet with the World IPv6 Launch led by the Internet Society. Within the first six months, IPv6 traffic broke the 1% threshold and established the fact that IPv6 had moved from an experiment to mainstream phase with US traffic approaching close to 3%. Join us for a discussion on where IPv6 is headed (Session ID: PSOSPG-1330) — new opportunities for IPv6 with Internet of Everything. We will be delighted to share our experiences deploying IPv6 (Session ID: PNLCRS-2303) as our IPv6 gurus highlight deployment best practices and real-world challenges. For those of you in Networking, we got you covered with the Troubleshooting IPv6 session (Session ID: BRKRST-2304).

E-VPN and PBB-EVPN Take Data Center Interconnect to the Next Level

Tina-lamBy Tina Lam, Product Manager

MPLS based Layer 2 VPN has been around for over 10 years since the inception of IETF Pseuduowire Edge to Edge (PWE3) Working Group. Many drafts and standards have been added, since then, to address different applications and to improve scale and convergence in different topologies. L2VPN as a whole is widely deployed in both service providers and enterprises, from Ethernet services, to fixed and mobile convergence, to enterprise campus layer-2 transport.

Recently, one emerging driver that has been picking up a lot of momentum is to use L2VPN for Data Center Interconnect (DCI). Data centers are often situated in different locations, to be geo-redundant for the purpose of workload mobility and business continuity. At the same time the physical location of the data center has to be transparent to users and to applications. Hence the need for layer-2 connectivity between sites. While Ethernet over MPLS (EoMPLS) and Virtual Private LAN Service (VPLS) have been used for this purpose, DCI presents new requirements and challenges not fully addressed today.  To keep the data center always on, and to utilize all the resources and links as efficiently as possible, data centers need all-active redundancy and load balancing. The technology should be as simple as possible to provision and manage Read More »
