Project Illustrates How Software Defined Network (SDN) and Network Functions Virtualization (NFV) Work in Concert to Enhance How Networks are Designed, Operated, and Monetized
Last week, I blogged about some joint research with Cox Communications related to our Evolved Services Platform (ESP) and NFV efforts. Another collaborative took place at the Society of Cable Telecommunications Engineers (SCTE) at their Cable-Tec Expo 14 event in Denver.
Loukas Paraschis, a Technology Solutions Architect at Cisco, co-wrote a paper (entitled SDN and NFV in Business Services) with Mazen Khaddam, Principal Lead Network Architect at Cox Atlanta.
The paper provides a comprehensive summary of Cisco’s SDN, NFV, and open source vision with the Cisco Evolved Services Platform (ESP). It specifically validates the service provider’s need for solutions that provide desired business outcomes for applications running across multiple domains (such as WAN and data center), and provides detailed use cases for the WAN Automation Engine (WAE).

The Fall ’14 Cisco Packet Optical Networking Conference (PONC) is quickly approaching – October 28-30 in Baveno & Vimercate, Italy. Don’t miss this opportunity to participate in this highly compelling and informative event (To learn more visit the Cisco PONC Series webpage).
If you are a PONC veteran, then you appreciate the value of this event – an opportunity to network with industry peers, hear directly from carriers leading the convergence evolution, see the latest technology innovations, and to have your voice heard.
If this will be your first PONC, then let me prepare you for this compelling event.
Cisco conducts this three day event twice a year –in the spring in San Jose California, and in the fall near its facilities in Vimercate, Italy. Read More »

Cisco estimates over 50 billion new devices will be connected to the Internet by 2020. To support the Internet of Everything, service providers must undergo an infrastructure transformation. The network needs to become more open, programmable, automated, adaptive, and agile. To guide this transformation, the Cisco open network strategy for service providers is depicted as three interwoven layers: the Evolved Programmable Network (physical and virtual network Infrastructure), the Evolved Services Platform (for orchestration of resources) and Applications and Services layer to enable virtualized services such as Cloud VPN and Security. With these three layers working together, providers can begin to realize the benefits of an open network that is readily open to new devices, open for quickly enabling new services, and open to endless possibilities.
Last week, Cisco announced two Read More »

This is part 2 of the “Your Business Powered By Cisco Customer Solutions Architecture (CSA)” blog series.
The following figure shows a simplified view of the Cisco CSA. It has five horizontal layers: Physical Infrastructure layer, Virtualized Infrastructure layer, Services layer, Service Management and Automation layer, and App/portal layer. Supporting each layer from top-to-bottom, there are three vertical layers: ITSM/ITIL services layer services enablement, Security layer for providing security across each of the horizontal layers, and Cisco Intellectual and domain management layer for providing Cisco best practices at each of the horizontal layers.
This CSA is a logically layered architecture (LLA), with each layer providing a distinct function. The model is designed in a hierarchical fashion with devices and facilities at the bottom, customer interactions at the top, and various required functionalities in the middle layers. The key to this model is the abstraction of each layer into software-defined components with standardized interfaces. Similar to other LLA models such as ITU-T TMN (Telecommunications Management Network), each horizontal layer supports the layer above in performing its business functions.
CSA Layered Approach
The interaction between various layers is through abstraction, orchestration, and API’s. The customers’ requests are processed from the top layer where orchestration fulfills the various components and provisions into the infrastructure using the API’s between the layers. Similarly, the Read More »

Network functions virtualization (NFV) and Software Defined Networking (SDN) will get a lot of interest this year at BBWF 2014 Broadband World Forum 2014 as carriers seek to make networks more agile and efficient. In talking to both service providers and large enterprises, it’s clear that we are already in another major transition in the networking industry.
I’ve spoken with many talented individuals about what NFV and SDN means to their networks. Some of these visions are very broad and long ranging and some are more narrowly focused on delivering or optimizing a single service very quickly. It’s clear that NFV has already been deployed in many different service applications while SDN has been noticeably slower to develop a focused following. Even in the case of Virtualized Network Functions (VNFs), there is an interesting combination of features focused on services delivery and features focused on infrastructure innovation. In this case “services” are typically the services that carriers sell to their end customers such as a Virtual Private Network (VPN) and “infrastructure” is the virtualization of the typical network functions such as a virtualized route reflector on an x86 based server instead of running the route reflector application in an existing (physical) router.
