SDN (Software Defined Networking) and NFV (Network Functions Virtualization) technologies are expected to help Service Providers gain new efficiencies and previously unimagined speed and agility in cloud services delivery so they can seize new business opportunities and achieve continued growth. Specifically, SDN in the data center helps you abstract services and applications from the complexities of the underlying network, making services operations drastically simpler. However, this abstraction layer, referred to as the SDN overlay, must meet very specific requirements to support today’s dynamic cloud environments.
I’d like to briefly discuss a recently released product, the Cisco Virtual Topology System (VTS), a high performance SDN overlay system designed to meet these requirements.
VTS is an important component of Cisco’s services management and orchestration software portfolio, aligned with Cisco’s Open Network Architecture and the Cisco Evolved Services Platform, a flexible and agile SP cloud service delivery platform. There are a number of capabilities of VTS Read More »

This post is about the onePK software architecture, and how it allows us to consistently expose network operating system (NOS) features to a wide variety of programming environments for IOS, IOS-XE, IOS-XR and NXOS.
For an overview of onePK in general, and some more context, see my October 2012 post and my slides in Slideshare.
The main elements of the onePK software architecture are illustrated Read More »

Cisco in the Hot Seat Addressing Alcatel-Lucent’s Core Network Offering
Service provider core networking has been a very difficult market segment for technology providers to penetrate based on its importance to global service providers and because it requires costly, ongoing innovation and investment to meet ever-changing customer requirements. While many vendors have attempted to enter this market – Avici and Caspian Networks come to mind – most have failed. In fact, Alcatel introduced a product in this space in the 2000s with the 7770. It was unsuccessful and ultimately discontinued.
While Cisco continues to be No. 1 in the core, we are not sitting on our hands by any means. In fact, our innovation engine is in high gear, and we are confident that we’ve got the right strategy to lead our customers into the next decade and beyond. Our architectural approach was designed to enable the best delivery of video and mobility by leveraging the network intersection points of the cloud, network, and client.

Public Service Announcement: Call Before You Dig (or “10 Most Bizarre and Annoying Causes of Fiber Cuts”)
At Cisco, we strive to provide the utmost in reliability and are particularly pleased with the market leading reliability we have with our IOS XR operating system on our ASR 9000 system and CRS routers. Whether it’s video, mobility, broadband or voice, reliability is key for a good experience. However, while we, at Cisco enable the experience, providers are the ones who deliver it – and in doing so, there are huge number of network heroes and heroines to make it happen. When it comes to fiber optic cable, someone somewhere actually has to go out and dig the trenches or hang the fibers, regardless of weather, critters, or angry land owners. This week on Lightreading.com, we saw an article worth sharing from our friends over at Level 3 Communications, “The 10 Most Bizarre and Annoying Causes of Fiber Cuts.” Read More »

With NAB in full swing this week, everyone is talking about delivering video services. Makes it a good time to discuss how Copenhagen (Denmark) based service provider Nianet has combined an extensive fiber deployment (100K+ km ) with a new investment in their IP network to offer video conferencing as a cloud service to business customers. For the small and medium sized business owner, you get big business productivity. Lease video conferencing on demand!
Nianet, which offers high-speed fiber communications throughout Denmark also distributes content from its sister company Waoo. They are now seeing the impact of companies increasingly producing their own video content, and therefore demanding faster and more symmetrical high speed data connections. The combination of fiber and high performance routers results in much faster speeds on both up and downstream.
“Businesses have really taken video communication as an alternative to physical meetings, and the technology is now spreading also from dedicated telepresence rooms for desktops and mobile devices. This places greater demands on both up and downstream, and Nianet has chosen to expand its backbone with twelve Cisco ASR 9000 routers to meet the increasing traffic and quality needs.
We also offer video conferencing as a cloud service to companies that want to begin with HD video communications. It therefore becomes easier to implement a full videoconferencing setup since we provide the server space, management software and plenty of bandwidth,” says Rasmus Helmich, CEO of Nianet.
