Decreasing New Services Time-to-Market with SDN and NFV

What are the easiest ways to add new services to an existing subscription? For subscribers of the service-orchestrated operator, the future looks bright. In fact, the future appears to be in the subscriber’s control.

One fundamental benefit of the operator network, facing the subscriber becoming more programmatically controlled through Software Defined Networking (SDN), is the introduction of ‘anything as a service’ (XaaS) concepts. Continue Reading

Virtualizing the Gateway – How CSPs are revolutionizing the network edge

In the Great SDN Expectations blog, the first in a series discussing the technologies of the future service network, we introduced the basic constructs of what Software Defined Networks mean to the platforms at the heart of the Communication Service Provider (CSP) network today. SDN itself represents a deconstructed view of current switching and routing architectures providing the abstractions of control from dataplane. With this newfound control, the industry is leveraging multiple virtualization strategies to build out public, private, and hybrid cloud architectures, delivering multiple new application services to the market.   Continue Reading

Great SDN Expectations

For many in the Cable industry, the Software Defined Network (SDN) continues to evade a precise definition, only to be further complicated when understanding its relationship to Network Function Virtualization (NFV). In this series of blog posts on SDN and NFV, we will explore both of these key topics in terms of their relationship to one another and the new products they enable. Continue Reading

5 reasons why you should adopt NFV for your CPEs

Communication service providers around the world are about to embark on an epic journey. A journey which has the potential to be a major game changer for hardware and software vendors alike. The simple concept of decoupling software from hardware, referred to as network functions virtualization (NFV), promises to improve an operator’s ability to differentiate themselves from the competition by moving network functions from dedicated appliances to generic commercial off-the-shelf (COTS) servers. This ability provides a wealth of benefits including service agility, cost reduction, and improved subscriber insight, all with vendor freedom on a future-proofed platform. Continue Reading

vCPE: The Turbo Button for Your Legacy Gateways

In my last blog, we explored the advantages of virtualizing network and gateway functions to reduce CAPEX and OPEX using virtual customer premises equipment (vCPE). But this raised a new question: Should service providers virtualize the entire network and gateway, or is it better to adopt a hybrid approach? Additionally, how long should you wait to transition to a virtual approach? Continue Reading

Is Network Virtualization Right for You?

Network Function Virtualization (NFV) is gaining momentum throughout the cable industry, but the long-term implications of this trend are yet to be seen. Though modern physical infrastructure equivalents are currently the most efficient way of provisioning and optimizing singular services, these hardware-based environments lack opportunities for service providers to customize their networks and address the dynamic and fluctuating bandwidth requirements brought on by booming multimedia services like OTT and P2P content.
