Much has been made of the emergence of Software Defined Networking and the programmable network. At its core, SDN involves opening up network interfaces in order to make the network programmable and allow for the development of applications. While some of those applications interact directly with the data plane, determining how individual packets are treated, many applications actually involve what can fundamentally be described as management functionality – automation of workflows, reaction to events, closing of control loops. A popular example concerns orchestration, in which resources are allocated and state modified so that collectively a service is provided – in many ways resembling a reincarnation of service provisioning in a new context and under a new name.
Of course, management applications and management interfaces have been around for a long time, so what is really new and different this time? Is SDN simply an exciting new label for a tired old concept? Does SDN obviate the need for traditional management? At the core of these questions are the concepts of programmability and manageability. Read More »

For those of you familiar with the movie “This is Spinal Tap” the volume on SDN has been turned up to 11 for some time. However, too much of the sound is around the technology and not on the benefits to network operators. In fact, Cisco views SDN technology and our Open Network Environment (ONE) as an opportunity for service providers to monetize and optimize their existing assets. In other words – leverage existing investments as much as possible and build SDN and programmatic Cisco ONE capabilities on top of them. Read More »

For those who are on the learning curve on various aspects of network programmability, open networking and SDN (like we are), I’d like to invite you to the third in a series of educational webicasts on these topics. Brought under the umbrella of the Cisco Open Network Environment, this particular webcast focuses on “An introduction to onePK”, and will be broadcast on April 9th, 2013 at 9 AM PST. You can register here.
The Cisco Open Network Environment is all about bringing the network closer to applications. One way of doing that is by exposing network devices to applications through a rich set of APIs, that can help tap into the intelligence inherent in the hardware and ASICs as well as in the network operating systems. This is what onePK is all about – it’s a single platform kit that will span all of Cisco’s network infrastructure portfolio across Enterprise and Service Provider, exposing them to applications in a homogenous way, allowing app developers to tap into the power of the open network.
Cisco announced its Open Network Environment or Cisco ONE strategy on June 2012 and has been in execution mode since then. onePK happens to be a key proofpoint of this cross-architectural strategy.
Join me on this webcast, as I host Ayman Sayed, SVP of Cisco’s Network Operating Systems Group as the lead Cisco expert on this topic. We will also be joined by two of the development partners that are working on onePK trials including Brendon Whateley, Principal Solution Architect at Starview Inc., and Kamil Knotek, Chielf of R&D at Pramacomm Prague spol s.r.o, as well as some new demos.
If you missed the last webcast on “An Introduction to OpenFlow” with David Ward, CTO, Cisco Engineering and Chief Architect, we had a turnout from 84 countries and over 120+ questions answered by our question managers in a one-hour period. You can watch a reply of the webcast here.

A few months back we announced how Hrvatski Telekom, Croatia’s largest telecommunications company, is using a Cisco’s end-to-end solution for its advanced TeraStream cloud-enabled Internet Protocol (IP) architecture. Operated by Deutsche Telekom subsidiary Hrvatski Telekom (T-HT), it’s initially providing broadband services to residential users in the Zagreb area of Croatia.

Segment routing (SR) is a concept that’s been working its way through the IETF standards process but is finally becoming ready for real world deployment. It’s a network technology that provides enhanced packet forwarding behavior while minimizing the need for maintaining awareness of mass volumes of network state. SR satisfies essential requirements for application-enabled routing in software defined networks, including the ability to provide strict network performance guarantees, efficient use of network resources and very high scalability for application-based transactions. Segment Routing relies on a small number of extensions to IS-IS and OSPF and can operate with an MPLS or an IPv6 data plane and integrates with the rich multi-service capabilities of MPLS such as L3VPN, VPWS, VPLS, E-VPN, etc.
